-record of information within <em>Subsurface</em> is a dive. The most important
-information in a simple dive logbook usually includes dive type, date, time,
-duration, depth, the names of your dive buddy and of the dive master or dive
-guide, and some remarks about the dive. <em>Subsurface</em> can store much more
-information than this for each dive. In order to add a dive to a dive log,
-select <em>Log → Add Dive</em> from the Main Menu. The program then shows three
-panels to enter information for a dive: two tabs in the <strong>Info</strong> panel
-(<strong>Notes</strong> and <strong>Equipment</strong>), as well as the <strong>Dive Profile</strong> panel that displays
-a graphical profile of each dive. These panels are respectively marked
-<span class="red">A</span>, <span class="red">B</span> and <span class="red">C</span> in the figure below. Each of these tabs will

-<em>Equipment</em> and <em>Profile</em> tabs should be completed before saving the
-information. By selecting the <em>Apply changes</em> button, a local copy of the
-information for this specific dive is saved in memory. When one closes
-Subsurface, the program will ask again, this time whether the complete dive
-log should be saved on disk or not.</p></div>

-<h4 id="S_CreateProfile">5.1.1. Creating a Dive Profile</h4>
-<div class="paragraph"><p>The <strong>Dive Profile</strong> (a graphical representation of the depth of the dive as a
-function of time) is indicated in the panel on the top right hand of the
-<em>Subsurface</em> window. When a dive is manually added to a logbook,
-<em>Subsurface</em> presents a default dive profile that needs to be modified to
-best represent the dive being described:</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="images/DiveProfile1_f20.jpg" alt="FIGURE: Initial dive profile" />

-</div>
-<div class="paragraph"><p><em>Modifying the dive profile</em>: When the cursor is moved around the dive
-profile, its position is indicated by two right-angled red lines as shown
-below.  The time and depth represented by the cursor are indicated at the
-top of the black information box (@ and D). The units (metric/imperial) on
-the axes are determined by the <strong>Preference</strong> settings. The dive profile
-itself comprises several line segments demarcated by waypoints (white dots
-on the profile, as shown above). The default dive depth is 15 m.  If the
-dive depth was 20 m then the user needs to drag the appropriate waypoints
-downwards to represent 20 m. To add a waypoint, double-click on any line
-segment. To move an additional waypoint, drag it.  To remove this waypoint,
-right-click on it and choose "Remove this point" from the context menu. Drag
-the waypoints to represent an accurate time duration for the dive. Below is
-a dive profile for a dive to 20 m for 30 min, followed by a 5 minute safety
-stop at 5 m.</p></div>

-indicated along the line segments of the dive profile. This defaults to the
-first gas mixture specified in the <strong>Equipment</strong> tab, which was air in the
-case of the profile above. The gas mixtures of segments of the dive profile
-can be edited. This is done by right-clicking on the particular waypoint and
-selecting the appropriate gas from the context menu. Changing the gas for a
-waypoint affects the gas shown in the segment <em>to the left</em> of that
-waypoint. Note that only the gases defined in the <strong>Equipment</strong> tab appear in

+record of information within <em>Subsurface</em> is a dive. The most important
+information in a simple dive logbook usually includes dive type, date, time,
+duration, depth, the names of your dive buddy and of the dive master or dive
+guide, and some remarks about the dive. <em>Subsurface</em> can store much more
+information than this for each dive. In order to add a dive to a dive log,
+select <em>Log → Add Dive</em> from the Main Menu. The program then shows three
+panels to enter information for a dive: two tabs in the <strong>Info</strong> panel
+(<strong>Notes</strong> and <strong>Equipment</strong>), as well as the <strong>Dive Profile</strong> panel that displays
+a graphical profile of each dive. These panels are respectively marked
+<span class="red">A</span>, <span class="red">B</span> and <span class="red">C</span> in the figure below. Each of these tabs will

+profile, its position is indicated by two right-angled red lines as shown
+below.  The time and depth represented by the cursor are indicated at the
+top of the black information box (@ and D). The units (metric/imperial) on
+the axes are determined by the <strong>Preference</strong> settings. The dive profile
+itself comprises several line segments demarcated by waypoints (white dots
+on the profile, as shown above). The default dive depth is 15 m.  If the
+dive depth was 20 m then the user needs to drag the appropriate waypoints
+downwards to represent 20 m. To add a waypoint, double-click on any line
+segment. To move an additional waypoint, drag it.  To remove this waypoint,
+right-click on it and choose "Remove this point" from the context menu. Drag
+the waypoints to represent an accurate time duration for the dive. Below is

+can be edited. This is done by right-clicking on the particular waypoint and

-<h4 id="S_DeviceNames">5.2.3. Changing the name of a dive computer</h4>
-<div class="paragraph"><p>It may be necessary to distinguish between different dive computers used to
-upload dive logs to <em>Subsurface</em>. For instance if one’s partner’s dive
-computer is the same make and model as one’s own and dive logs are uploaded
-from both dive computers to the same <em>Subsurface</em> computer, then one would
-perhaps like to call one dc "Alice’s Suunto D4" and the other one "Bob’s
-Suunto D4". Alternatively, consider a technical diver dives with two or more
-dive computers of the same model, the logs of both (or all) being uploaded.
-In this case it might be prudent to call one of them "Suunto D4 (1)" and
-another one "Suunto D4 (2)". This is easily done in <em>Subsurface</em>.  On the
-<strong>Main Menu</strong>, select <em>Log → Edit device names</em>. A dialog opens, indicating
-the current Model, ID and Nickname of the dive computers used for
-upload. Edit the Nickname field for the appropriate dive computer. After
-saving the Nickname, the dive logs show the nickname for that particular

-<div class="paragraph"><p>In some cases, one has to provide the date and time of the dive, e.g. when
-entering a dive by hand or when a dive computer does not provide the date
-and time of the dive.  (Usually the date and time of the dive, gas mixture
-and water temperature are shown as obtained from the dive computer)  If the
-contents of the <strong>Notes tab</strong> is changed or edited in any way, the message in

-<div class="paragraph"><p><strong>Air/water temperatures</strong>: Air and water temperatures during the dive are shown
-in text boxes to the right of the Start time. Many dive computers supply water
-temperature information and this box may therefore contain information.
-If air temperature is not provided by the dive computer, the first temperature reading
-might be used for the air temperature. Generally this is close enough to the real air temperature as
-the change in the temperature sensor reading is quite slow to follow the changes in the environment.

-items of information in the <strong>Notes</strong> tab (e.g. water temperature) and in the
-<strong>Equipment</strong> tab (e.g. gas pressures and gas composition). However the other
-fields remain empty.  It may be useful to simultaneously edit some of the
-fields in the <strong>Notes</strong> and <strong>Equipment</strong> tabs.  For instance, it is possible
-that a diver performed several dives during a single day, using identical
-equipment while diving at the same dive site or with the same dive master
-and/or buddy or tags. Instead of completing the information for each of
-these dives separately, one can select all the dives for that day in the
-<strong>Dive List</strong> and insert the same information in the <strong>Notes</strong> and <strong>Equipment</strong>
-fields that need identical information. This is achieved by editing the dive
-notes or the equipment for any one of the selected dives.</p></div>
-<div class="paragraph"><p>The simultaneous editing only works with fields that do not already contain
-information.  This means that, if some fields have been edited for a
-particular dive among the selected dives, these are not changed while
-editing the dives simultaneously. Technically, the rule for editing several
-dives simultaneously is: if the data field being edited contains <em>exactly
-the same information</em> for all the dives that have been selected, the new,
-edited information is substituted for all the selected dives, otherwise only
-the edited dive is changed, even though several dives have been selected in
-the <strong>Dive List</strong>. This greatly speeds up the completion of the dive log after
-several similar dives.</p></div>
-<div class="paragraph" id="S_CopyComponents"><p><em>METHOD 2</em>:There is a different way of achieving the same goal. Select a

-be imported by <em>Subsurface</em>.  Currently, <em>Subsurface</em> supports importing CSV
-log files from several sources.  APD LogViewer, XP5, Sensus and Seabear
-files are preconfigured, but because the import is flexible, users can
-configure their own imports.  Manually kept log files (e.g. a spreadsheet)
-can also be imported by configuring the CSV import.  <em>Subsurface</em> can also
-import UDDF and UDCF files used by some divelog software and some dive
-computers, like the Heinrichs & Weikamp DR5. Finally, for some divelog
-software like Mares Dive Organiser it is currently suggested to import the
-logbooks first into a webservice like <em>divelogs.de</em> and then import them
-from there with <em>Subsurface</em>, as divelogs.de supports a few additional

-   dive duration, names of buddy and dive master and perhaps some information
-   about cylinder pressures before and after the dive, as well as a comment or

-   text, following the order of the column headings.
-</p>
-</li>
-<li>
-<p>
-<em>CSV dive profile</em>: This dive log format includes much more information
-   about a single dive. For instance there may be information at 30-second
-   intervals, indicating depth, water temperature at that depth, and cylinder
-   pressure at that moment in time. Each line contains the information for a
-   single instant in time during the dive, 30 seconds after that of the
-   previous instant. Many lines are required to complete the depth profile
-   information for a single dive. This is a common export format used by
-   closed-circuit rebreather (CCR) dive equipment and many software packages
-   that handle dive computer data and/or dive logs.
-</p>
-</li>
-</ol></div>
-<div class="paragraph"><p>Before being able to import the <em>CSV</em> data to <em>Subsurface</em> <strong>one needs to
-know a few things about the data being imported</strong>:</p></div>
-<div class="olist loweralpha"><ol class="loweralpha">
-<li>
-<p>
-Which character separates the different columns within a single line of
-   data? This field separator should be either a comma (,) a semicolon (;) or a
-   TAB character.  This can be determined by opening the file with a text
-   editor. If it is comma-delimited or semicolon-delimited, the comma or
-   semicolon characters between the values are clearly visible. If these are
-   not evident and the numbers are aligned in columns, the file is probably
-   TAB-delimited (i.e. it uses a TAB as a field separator).
-</p>
-</li>
-<li>
-<p>
-Which data columns need to be imported into <em>Subsurface</em>? Is it a <em>CSV dive
-   details</em> file or a <em>CSV dive profile</em> file? Open the file using a text
-   editor and note the titles of the columns to be imported and their column
-   positions.
-</p>
-</li>
-<li>
-<p>
-Is the numeric information (e.g. dive depth) in metric or in imperial unis?
-</p>
-</li>
-</ol></div>
-<div class="paragraph"><p>Armed with this information, importing the data into <em>Subsurface</em> is
-straightforward. Select <em>Import → Import Log Files</em> from the main menu. In
-the resulting file selection menu, select <em>CSV files</em> (towards the bottom
-right). This shows all .CSV files in the selected directory. Select the file
-that needs to be imported. A configuration panel appears as depicted below:</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="images/csv_import1_f20.jpg" alt="FIGURE: CSV download dialogue 1" />

-</div>
-<div class="paragraph"><p>Notice that, at the top left, there is a dropdown list containing
-pre-configured settings for some of the more common dive computers and
-software packages encountered by divers. If the <em>CSV</em> file being imported
-originated from any of these pre-configured items, then select it. Otherwise
-use the <em>Manual Import</em> option. The configuration panel also has dropdown
-lists for the specification of the appropriate field separator (Tab, comma
-or semicolon), the date format used in the <em>CSV</em> file, the time units
-(seconds, minutes or minutes:seconds), as well as the unit system (metric or
-imperial). Selecting the appropriate options among these is critical for the
-successful import of the data.</p></div>
-<div class="paragraph"><p>The last remaining task is to ensure that all the data columns have the
-appropriate column headings. The top blue row of the data table contains the
-column headings found in the <em>CSV</em> data file. The blue row of balloons
-immediately above these contains the names understood by <em>Subsurface</em>. These
-balloons can be moved using a drag-and-drop action. For instance,
-<em>Subsurface</em> expects the column heading for Dive number (" # ") to be "Dive
-# ". If the column heading that <em>Subsurface</em> expects is not in the blue row,
-then drag the appropriate balloon from the upper area and drop it in the
-appropriate blue cell at the top of the table. To indicate the correct
-column for "Dive #", drag the ballooned item labeled "Dive # " and drop it
-in the blue cell immediately above the white cell containing " # ". This is

-<img src="images/LoadImage2_f20.jpg" alt="FIGURE: Load images option" />
-</div>
-</div>
-<div class="paragraph"><p>This brings up the time synchronisation dialog, shown below. The critical
-problem is that the time synchronisation is not perfect between the dive
-computer used during a dive, and the camera used during that same
-dive. These two devices often differ by several minutes. If <em>Subsurface</em> can
-achieve synchronisation, then the exact times of photographs can be used to
-position photographs on the dive profile.</p></div>
-<div class="paragraph"><p><em>Subsurface</em> achieves this synchronisation in three ways:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Pro-actively</strong>: Before the dive, ensure synchronisation of the dive computer time settings with
-  the time settings of the camera by changing the date-time settings on one or both of these devices.
-</p>
-</li>
-<li>
-<p>
-<strong>Manually</strong>: If the user wrote down the exact camera time at the start of a dive, the
-  difference in time between the two devices can be determined. Actually, as long as the device
-  settings for time has not been changed in either device, one could write down the times of
-  both devices after the dive or even at the end of the day. One can then manually set the time
-  difference in the <em>Time shift</em> dialog. Towards the top of the dialog is a time setting tool
-  immediately under the heading <em>Shift times of image(s) by</em>, evident in figure <strong>A</strong> below.
-  If the camera time is 7 minutes later than that of the dive computer, set the time setting
-  tool to a value of 00:07.  Select either the <em>earlier</em> or <em>later</em> radio button.
-  In the above example, the <em>earlier</em> option is appropriate, since the photos need to be shifted
-  7 minutes earlier (camera is 7 minutes ahead of dive computer). Ignore any "AM" or "PM" suffix
-  in that tool. Click the <em>OK</em> button and synchronisation is achieved.
-</p>

-</div>
-</div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>By photograph</strong>: There is a very slick way of achieving synchronisation. If one takes a
-  photograph of the face of the dive computer showing the time, then <em>Subsurface</em> can obtain
-  the exact time the photograph was taken, using the metadata that the camera stores within
-  each photo. In order to do this, use the bottom half of the <em>Time shift</em> dialog. If one uses
-  the bottom part, the top part of the dialog is ignored. Click on
-  the horizontal bar entitled "<em>Select image of divecomputer showing time</em>. This brings up
-  a file browser with which one can select the photograph of the dive computer time. Select the
-  photograph using the file browser and click on <em>OK</em>. This photograph of the dive computer
-  appears in the bottom panel of the <em>Shift times</em> dialog. Now <em>Subsurface</em> knows exactly
-  when the photograph has been taken. Now set the date-time dialog to the left of the photo
-  so that this tool reflects the date and time of the dive computer in the photo. When the
-  date-time tool has been set, <em>Subsurface</em> knows exactly what the time difference between
-  camera and dive computer is, and synchronisation is achieved.
-  Image <strong>B</strong> above shows a photograph of the face of the dive computer and with the date-time tool set to the
-  date-time.

-the photos can be directly accessed by <em>Subsurface</em>. This facilitates the
-interaction between <em>Subsurface</em> and an external repository of photos. When
-associating a dive profile with photos from an external drive, the normal
-procedure of selection and synchronisation (see text above) is used.
-However, after the external drive has been disconnected, <em>Subsurface</em> cannot
-access these photos any more.  If the display of photos is activated (using
-the toolbox to the left of the <em>Dive Profile</em>), the program only shows a
-small white dot where each photo should be on the dive profile.  In addition
-the <em>Photos</em> tab only shows the file names of the photos. This is normal

-<h4 id="S_FindMovedImages">5.5.5. Moving photographs among directories, hard disks or computers</h4>
-<div class="paragraph"><p>After a photograph has been loaded into <em>Subsurface</em> and associated with a specific dive, the directory
- where the photo lies is stored, allowing <em>Subsurface</em> to find the photograph when the dive is
- opened again. If the photo or the whole photo collection is moved to another drive or to a different
- machine, it is unlikely that the directory structure will remain identical to that of the original uploaded
- photo. When this happens, <em>Subsurface</em> looks for the photos at their original location before they were moved,
- cannot find them and therefore cannot display them. Because, after moving photos, large numbers of photos
- may need to be deleted and re-imported from the new location, <em>Subsurface</em> has a mechanism that eases the
- process of updating the directory information for each photo: automatic updates using fingerprints.</p></div>
-<div class="paragraph"><p>When a photo is loaded into <em>Subsurface</em>, a fingerprint for the image is calculated and stored with the
- other reference information for that photo. After moving a photo collection (that has already been loaded
- into <em>Subsurface</em>) to a different directory, disk or computer, <em>Subsurface</em> can  perform the
- following steps:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-look through a particular directory (and all its subdirectories recursively)
-  where photos have been moved

-</li>
-<li>
-<p>
-if there is a match between a calculated fingerprint and the one originally

-</ul></div>
-<div class="paragraph"><p>This is achieved by selecting from the Main Menu: <em>File →      Find moved images</em>. This brings up a window within

-needs more than one gas mixture because of the depth or the decompression
-needs of the dive. For this reason multicylinder dives are often used by

-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Describe the cylinders used during the dive</strong> This is performed in the <strong>Equipment tab</strong> of
-  the <strong>Info</strong> panel, as <a href="#cylinder_definitions">described above</a>. Enter the cylinders one by one,
-  specifying the characteristics of the cylinder and the gas composition within each cylinder.
-</p>
-</li>
-<li>
-<p>
-<strong>Record the times at which switches from one cylinder to another was done:</strong> This is information
-  provided by some dive computers (provided the diver indicated these changes to the dive computer
-  by pressing specific buttons). If the dive computer does not provide the information, the diver has to
-  record these changes using a different method, e.g. writing it on a slate.
-</p>
-</li>
-<li>
-<p>
-<strong>Record the cylinder changes on the dive profile</strong>: If the latter option
-  was followed, the diver needs to indicate the gas change event by right-clicking at the appropriate point
-  in time on the <strong>Dive Profile</strong> panel and indicating the cylinder to which the change was made. After
-  right-clicking, follow the context menu to "Add gas change" and select the appropriate cylinder from

-configuration for cave divers, sidemount diving can be performed by
-recreational divers who have completed the appropriate training. Sidemount
-dive logging involves, exactly as with multicylinder dives, above, three
-steps:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>During the dive, record cylinder switch events</strong>. Since sidemount diving normally involves two
-  cylinders with air or with the same gas mixture, <em>Subsurface</em> distinguishes among these different
-  cylinders. In contrast, many dive computers that allow gas switching only distinguish among different
-  <em>gases</em> used, not among different <em>cylinders</em> used. This means that when sidemount dives are downloaded
-  from these dive computers, the events of switching between cylinders with the same gas are not downloaded. This may mean

-a ceiling for non-decompression dives when the dive computer stayed in
-non-deco mode during the whole dive (represented by the <span class="green">dark green</span>
-section in the profile at the beginning of this section). This is caused by
-the fact that <em>Subsurface’s</em> calculations describe the deco obligation at

-the mouse cursor is over the Dive Profile panel. The menu allows the
-creation of Bookmarks or Gas Change Event markers or manual CCR set-point
-changes other than the ones that might have been imported from a Dive
-Computer. Markers are placed against the depth profile line and with the
-time of the event set by where the mouse cursor was when the right mouse

-a selection of which gas is being switched to, the list of choices being
-based on the available gases defined in the <strong>Equipment</strong> Tab. Set-point
-change events open a dialog allowing to choose the next set-point value. As
-in the planner, a set-point value of zero indicates the diver is breathing
-from an open circuit system while any non-zero value indicates the use of a
-closed circuit rebreather (CCR).  By right-clicking while over an existing

-<em>Subsurface XML</em> format. This is the native format used by <em>Subsurface</em>.
-</p>
-</li>
-<li>
-<p>
-Universal Dive Data Format (<em>UDDF</em>). Refer to <em>http://uddf.org</em> for more
-  information.  UDDF is a generic format that enables communication among many
-  dive computers and computer programs.
-</p>
-</li>
-<li>
-<p>
-<em>Divelogs.de</em>, an Internet-based dive log repository. In order to upload to
-  <em>Divelogs.de</em>, one needs a user-ID as well as a password for
-  <em>Divelogs.de</em>. Log into <em>http://en.divelogs.de</em> and subscribe to this
-  service in order to upload dive log data from <em>Subsurface</em>.
-</p>
-</li>
-<li>
-<p>
-<em>DiveShare</em> is also a dive log repository on the Internet focusing on the
-  recreational dives. In order to upload dives one has to provide a used ID,
-  so registration with <em>http://scubadiveshare.com</em> is required.
-</p>
-</li>
-<li>
-<p>
-<em>CSV dive details</em>, that includes the most critical information of the dive
-  profile. Included information of a dive is: dive number, date, time, buddy,
-  duration, depth, temperature and pressure: in short, most of the information
-  that recreational divers enter into handwritten log books.
-</p>
-</li>
-<li>
-<p>
-<em>CSV dive profile</em>, that includes a large amount of detail for each dive,
-  including the depth profile, temperature and pressure information of each
-  dive.
-</p>
-</li>
-<li>
-<p>
-<em>HTML</em> format, in which the dive(s) are stored in HTML files, readable with
-  an Internet browser. Most modern web browsers are supported, but JavaScript
-  must be enabled. The HTML export cannot be changed or edited.  It contains
-  most of the information recorded in the dive log. However, it does not show
-  the calculated values in the <strong>Dive Profile</strong> panel, e.g. calculated cylinder
-  pressure, gas pressures and MOD. The HTML export contains a search option to
-  search the dive log. HTML export is specified on the second tab of the
-  Export dialog (image <strong>B</strong> above). A typical use of this option is to export
-  all one’s dives to a smartphone or a tablet where it would serve as a very
-  portable record of dives useful for dive companies that wish to verify the
-  dive history of a diver, often doing away with the need to carry one’s
-  original logbook with one when doing dives with dive companies.
-</p>
-</li>

-<h2 id="S_Cloud_access">9. Keeping a <em>Subsurface</em> dive log in the Cloud</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>For each diver, dive log information is highly important. Not only is it a
-record of diving activities for one’s own pleasure, but it is important
-information required for admission to further training courses or
-(sometimes) even diving sites. The security of the dive log is therefore
-critical. In order to have a dive log that is resistant to failure of a home
-computer hard drive, loss or theft of equipment, the Cloud is an obvious
-solution. This also has the added benefit that one can access one’s dive log
-from anywhere in the world without having to carry it with oneself. For this
-reason, facilities such as <em>divelogs.de</em> and <em>Diving Log</em> offer to store
-dive log information on the Internet.</p></div>
-<div class="paragraph"><p><em>Subsurface</em> includes access to a transparently integrated cloud storage
-backend that is available to all Subsurface users. Storing and retrieving a
-dive log from the cloud is no more difficult than accessing the dives on the
-local hard disk.  The only requirement is that one should first register as
-a user on the cloud.  To use <em>Subsurface cloud storage</em> , follow these
-steps:</p></div>
-<div class="sect2">
-<h3 id="_create_a_cloud_storage_account">9.1. Create a cloud storage account</h3>
-<div class="ulist"><ul>
-<li>
-<p>
-Open the <strong>Network Preferences</strong> by selecting <em>File</em> → <em>Preferences</em> → <em>Network</em>.
-</p>
-</li>
-<li>
-<p>
-In the section headed <em>Subsurface cloud storage</em>, enter an email address that
-   <em>Subsurface</em> can use for user registration.
-</p>
-</li>
-<li>
-<p>
-Enter a novel password that <em>Subsurface</em> will use to store the
-  dive log in the cloud.
-</p>
-</li>
-<li>
-<p>
-Click <em>Apply</em> to send the above email address and password to the
-  (remote) cloud server. The server responds by sending a verification PIN to
-  the above email address (This is the <strong>only</strong> occasion that <em>Subsurface</em> uses the
-  email address provided above). The <strong>Network Preferences</strong> dialog now has a new PIN text
-   box, not visible previously.
-</p>
-</li>
-<li>
-<p>
-Enter the PIN in the corresponding text box in the <strong>Network Preferences</strong> dialog
-(this field is only visible while the server is waiting for email
-address confirmation)
-</p>
-</li>
-<li>
-<p>
-Click <em>Apply</em> again. The <em>Subsurface cloud storage</em> account
-will be marked as verified and the <em>Subsurface cloud storage</em> service is initialised for use.
-</p>
-</li>
-</ul></div>
-</div>
-<div class="sect2">
-<h3 id="_using_em_subsurface_cloud_storage_em">9.2. Using <em>Subsurface cloud storage</em></h3>
-<div class="ulist"><ul>
-<li>
-<p>
-Once the cloud storage has been initialised, two new items appear in the
-   <em>File</em> menu of the main menu system: <em>Open cloud storage</em> and <em>Save to cloud storage</em>.
-These options allow the user to load and save data to the <em>Subsurface
-cloud storage</em> server.
-</p>
-</li>
-<li>
-<p>
-In the <em>Defaults Preferences</em> tab, one can select to use the <em>Subsurface cloud
-storage</em> data as one’s default data file by checking the check box marked <em>Cloud storage default file</em>.
- This means that the data from
-the <em>Subsurface cloud storage</em> is loaded when <em>Subsurface</em> starts ans saved there when one closes <em>Subsurface</em>.
-</p>
-</li>
-<li>
-<p>
-<em>Subsurface</em> keeps a local copy of the data and the cloud facility remains fully
-functional even if used while disconnected to the Internet. <em>Subsurface</em> simply synchronises the
-data with the cloud server the next time ithe program is used while the computer is
-connected to the Internet.
-</p>
-</li>
-</ul></div>
-</div>
-<div class="sect2">
-<h3 id="S_Cloud_storage">9.3. Web access to <em>Subsurface cloud storage</em></h3>
-<div class="paragraph"><p>One of the nice side benefits of using <em>Subsurface cloud storage</em> is that
-one can also access one’s dive data from any web browser. Simply open
-<a href="https://cloud.subsurface-divelog.org"><em>https://cloud.subsurface-divelog.org</em></a>,
-log in with the same email and password, and you can see an HTML export of
-the last dive data that was synced to the <em>Subsurface cloud storage</em>. The
-dive information that is shown is only the contents of the recorded dive
-logs, NOT the calculated values shown in the <strong>Profile</strong> panel, including some
-cylinder pressures, deco ceilings and O<sub>2</sub>/He/N<sub>2</sub> partial pressures.</p></div>
-</div>
-<div class="sect2">
-<h3 id="_other_cloud_services">9.4. Other cloud services</h3>
-<div class="paragraph"><p>If one prefers not to use the integrated cloud storage of dive logs (and
-don’t need the web access), it is also simple to store dive logs in the
-cloud using several of the existing facilities on the Internet.  For
-instance <a href="http://www.dropbox.com/"><em>Dropbox</em></a> offers a free application that
-allows files on the Dropbox servers to be seen as a local folder on one’s
-desktop computer.</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="images/Cloud.jpg" alt="FIGURE: Dropbox folder" />
-</div>
-</div>
-<div class="paragraph"><p>The <em>Dropbox</em> program creates a copy of the <em>Dropbox</em> Internet Cloud content
-on one’s desktop computer. When the computer is connected to the Internet,
-the Internet content is automatically updated. Therefore both the <em>Open</em> and
-<em>Save</em> of dive logs are done using the local copy of the dive log in the
-local <em>Dropbox</em> folder, so there’s no need for a direct internet
-connection. If the local copy is modified, e.g. by adding a dive, the remote
-copy in the <em>Dropbox</em> server in the Cloud will be automatically updated
-whenever Internet access is available.</p></div>
-<div class="paragraph"><p>In this way a dive log in one’s <em>Dropbox</em> folder can be accessed seamlessly
-from the Internet and can be accessed from any place with Internet
-access. Currently there are no costs involved for this service. Dropbox
-(Windows, Mac and Linux) can be installed by accessing the
-<a href="http://www.dropbox.com/install"><em>Install Page on the Dropbox website</em></a>
-Alternatively one can use <em>Dropbox</em> as a mechanism to backup one’s dive
-log. To Store a dive log on <em>Dropbox</em>, select <em>File → Save as</em> from the
-<em>Subsurface</em> main menu, navigate to the <em>Dropbox</em> folder and select the
-<em>Save</em> button. To access the dive log in <em>Dropbox</em>, select <em>File → Open
-Logbook</em> from the <em>Subsurface</em> main menu and navigate to the dive log file
-in the <em>Dropbox</em> folder and select the <em>Open</em> button.</p></div>
-<div class="paragraph"><p>Several paid services exist on the Internet (e.g. Google, Amazon) where the
-same process could be used for the Cloud-based storage of dive logs.</p></div>

-   the value of a gradient factor, the more conservative the calculations are with
-   respect to nitrogen loading and the deeper the ascent ceilings are. Gradient

-<h4 id="_recreational_dives">13.2.1. Recreational dives</h4>
-<div class="paragraph"><p>The <em>Subsurface</em> dive planner allows a sophisticated way of planning
-recreational dives, i.e. dives that remain within no-decompression limits.
-The dive planner automatically takes into account the nitrogen load incurred
-in previous dives. But conventional dive tables are also used in a way that
-can take into account previous dives. Why use a dive planner for
-recreational dives? Using recreational dive tables, the maximum depth of a
-dive is taken into acount. However, few dives are undertaken at a constant
-depth corresponding to the maximum depth (i.e. a "square" dive
-profile). This means that dive tables overestimate the nitrogen load
-incurred during previous dives. The <em>Subsurface</em> dive planner calculates
-nitrogen load according to the real dive profiles of all uploaded previous
-dives, in a similar way as dive computers calculate nitrogen load during a
-dive. This mean that the diver gets <em>credit</em> in terms of nitrogen loading
-for not remaining at maximum depth during previous dives, enabling planning
-a longer subsequent dive. For the planner to work it is therefore crucial to
-upload all previous dives onto <em>Subsurface</em> before performing dive planning.</p></div>
-<div class="paragraph"><p>To plan a dive, the appropriate settings need to be defined.</p></div>
-<div class="paragraph"><p>Ensure that the date and time is set to that of the intended dive. This
-allows calculation of the nitrogen load incurred during previous dives.</p></div>
-<div class="ulist"><ul>

-Immediately under the heading <em>Planning</em> are two checkboxes <em>Recreational</em>
-  and <em>Safety Stop</em>.  Check these two boxes.

-Then define the cylinder size, the gas mixture (air or % oxygen) and the
-  starting cylinder pressure in the top left-hand section of the planner under
-  <em>Available gases</em>.
-</p>
-</li>
-<li>
-<p>
-The planner calculates whether the specified cylinder contains enough
-  air/gas to complete the planned dive. In order for this to be realistic,
-  under <em>Gas options</em>, specify an appropriate surface air consumption (SAC)
-  rate for <em>Bottom SAC</em>. Suitable values are between 15 l/min and 30 l/min,
-  with novice divers or difficult dives requiring SAC rates closer to 30l/min.
-</p>
-</li>
-<li>
-<p>
-Define the amount of gas that the cylinder must have at the end of the
-  bottom section of the dive just before ascent. A value of 50 bar is often
-  used.
-</p>
-</li>
-<li>
-<p>
-Define the depth of the dive by dragging the waypoints (white dots) on the
-  dive profile or (even better) defining the appropriate depths using the
-  table under <em>Dive planner points</em> as desribed under the previous heading. If
-  this is a multilevel dive, set the appropriate dive depths to represent the

-<div class="paragraph"><p>The dive profile in the planner indicates the maximum dive time within
-no-deco limits using the Bühlmann ZH-L16 algorithm and the gas and depth
-settings specified as described above. The <em>Subsurface</em> planner allows rapid
-assessment of dive duration as a function of dive depth, given the nitrogen
-load incurred during previous dives. The dive plan includes estimates of the
-amount of air/gas used, depending on the cylinder settings specified under
-<em>Available gases</em>. If the initial cylinder pressure is set to 0, the dive
-duration shown is the true no-deco limit (NDL) without taking into account
-gas used during the dive. If the surface above the dive profile is RED it

-<div class="paragraph"><p>Below is an image of a dive plan for a recreational dive at 30

-<div class="paragraph"><p>Non-recreational dive planning involves exceeding the no-deco limits and/or
-using multiple breathing gases.  Such dives are planned in three stages:</p></div>
-<div class="paragraph"><p><strong>a) Nitrogen management</strong>: This is performed by specifying the rates for descent and ascent,
-as well as the deco model (GFLow, GFHigh or Conservatism level) under the headings <em>Rates</em> and <em>Planning</em>
-to the bottom left of the planning screen. Two deco models are supported the Bühlmann model and the VPM-B
-model. Select one of the two models. When selecting the Bühlmann model, the gradient factors (GF_high and GF_low
-need to be specified. Initially, the GFHigh and GFLow values in the <em>Preferences</em>
-panel of <em>Subsurface</em> is used. If these are changed within the planner (see <em>Gas Options</em> within
-the planner), the new values are
-used without changing the original values in the <em>Preferences</em>. Gradient Factor settings strongly affect the calculated ceilings and their depths.
-A very low GFLow value brings about decompression stops early on during the dive.
- ** For more information about Gradient factors, see the section on <a href="#S_GradientFactors">Gradient Factor Preference settings</a>.</p></div>
-<div class="paragraph"><p>If the VPM-B model is selected, the Conservatism_level needs to be specified
-on a scale of 0 (least conservative) to 4 (most conservative).  This model
-tends to give deco stops at deeper levels than the Bühlmann model and often
-results in slightly shorter dive durations than the Bühlmann model. When
-selecting one of these models, keep in mind that they are NOT exact

-<div class="paragraph"><p><strong>b) Oxygen management</strong>: In the <strong>Gas Options</strong> part of the dive specification, the maximum partial
-pressure for oxygen needs to be specified for the
-bottom part of the dive (<em>bottom po2</em>) as well as for the decompression part of the dive (<em>deco po2</em>).
-The most commonly
-used values are 1.4 bar for the bottom part of the dive and 1.6 bar for any decompression
-stages. Normally, a partial pressure of 1.6 bar is not exceeded. PO2 settings and the depth at which switching to a gas takes place can also be edited in the
-<em>Available Gases</em> dialog. Normally the planner decides on switching to a new gas when, during
-ascent, the partial pressure of the new gas has increased to 1.6 bar.</p></div>
-<div class="paragraph"><p><strong>c) Gas management</strong>: With open-circuit dives this is a primary consideration. One needs to keep within the limits of the amount of gas within the dive
-cylinder(s), allowing for an appropriate margin for a safe return to the surface, possibly
-sharing with a buddy. Under the <em>Gas Options</em> heading, specify the best (but conservative) estimate
-of your surface-equivalent air consumption (SAC, also termed RMV) in
-litres/min (for the time being, only SI units are supported).  Specify the SAC during the
-bottom part of the dive (<em>bottom SAC</em>) as well as during the decompression or safety stops of the
-dive (<em>deco SAC</em>). Values of 15-30 l/min are common. For good gas management, a thumbsuck guess
-is not sufficient and one needs to
-monitor one’s gas consumption on a regular basis, dependent on different dive conditions and/or equipment.
-The planner calculates the total volume of gas used during the dive and issues a warning
-if one exceeds the total amount of gas available. Good practice demands that one does not dive to
-the limit of the gas supply but that an appropriate reserve is kept for unforeseen circumstances.
-For technical diving, this reserve can be up to 66% of the total available gas.</p></div>
-<div class="paragraph"><p>Now (at last) one can start the detailed time-depth planning of the
-dive. <em>Subsurface</em> offers a unique graphical interface for performing this
-part of the planning. The mechanics of doing this is similar to
-hand-entering a dive profile in the dive log part of <em>Subsurface</em>. Upon
-activating the planner, a default dive of depth 15 m for 40 min is offered
-in the bue design surface to the top right hand of the screen. The white
-dots (waypoints) on the profile can be dragged with a mouse. Create more
-waypoints by double-clicking on the profile line and ensuring that the
-profile reflects the intended dive. Drag the waypoints to represent the
-depth and duration of the dive. It is NOT necessary to specify the ascent
-part of the dive since the planner calculates this, based on the settings
-that have been specified.  If any of the management limits (for nitrogen,
-oxygen or gas) is exceeded, the surface above the dive profile changes from
-BLUE to RED.</p></div>
-<div class="paragraph"><p>Each waypoint on the dive profile creates a <em>Dive Planner Point</em> in the
-table on the left of the dive planner panel. Ensure that the <em>Used Gas</em>
-value in each row of that table corresponds to one of the gas mixtures
-specified in the <em>Available Gases</em> table.  Add new waypoints until the main
-features of the dive have been completed, e.g. the bottom time segment and
-deep stops (if these are implemented). Leave the remaining waypoints on the
-ascent to <em>Subsurface</em>. In most cases <em>Subsurface</em> computes additional way
-points in order to fulfil decompression requirements for that dive. A
-waypoint can be moved by selecting that waypoint and by using the arrow
-keys.  The waypoints listed in the <em>Dive Planner Points</em> dialogue can be
-edited by hand in order to obtain a precise presentation of the dive
-plan. In fact, one can create the whole dive profile by editing the <em>Dive
-Planner Points</em> dialog.</p></div>
-<div class="paragraph"><p>Indicate any changes in gas cylinder used by indicating gas changes as
-explained in the section <a href="#S_CreateProfile">hand-creating a dive profile</a>. These changes should reflect the cylinders and gas compositions
-defined in the table with <em>Available Gases</em>.  If two or more gases are used,
-automatic gas switches will be suggested during the ascent to the
-surface. However, these changes can be deleted by right-clicking the gas
-change and by manually creating a gas change by right-clicking on the
-appropriate waypoint.</p></div>
-<div class="paragraph"><p>A non-zero value in the "CC set point" column of the table of dive planner
-points indicates a valid setpoint for oxygen partial pressure and that the
-segment is dived using a closed circuit rebreather (CCR). If the last
-manually entered segment is a CCR segment, the decompression phase is
-computed assuming the diver uses a CCR with the specified set-point. If the
-last segment (however short) is on open circuit (OC, indicated by a zero
-set-point) the decompression is computed in OC mode. The planner only
-considers gas changes in OC mode.</p></div>
-<div class="paragraph"><p>Below is an example of a dive plan to 45m using EAN26, followed by an ascent
-using EAN50 and using the settings as described above.</p></div>

-planner, immediately to the left of the <em>Dive Plan Details</em>. If a <em>Verbatim

-plan is given. If any of the management specifications have been exceeded
-during the planning, a warning message is printed underneath the dive plan
-information.</p></div>
-<div class="paragraph"><p>If the option <em>Display segment duration</em> is checked, then the duration of
-each depth level is indicated in the <em>Dive Plan Details</em>. This duration

-<h3 id="_planning_pscr_dives">13.3. Planning pSCR dives</h3>
-<div class="paragraph"><p>To plan a dive using a passive semi-closed rebreather (pSCR), select <em>pSCR</em> rather than
-<em>Open circuit</em> in the dropdown list.
-The parameters of the pSCR dive can be set by selecting  <em>File →   Preferences →   Graph</em>
-from the main menu, where the gas consumption calculation takes into account the pSCR dump
-ratio (default 10:1) as well as the metabolism rate. The calculation also takes the oxygen drop
-accross the mouthpiece of the rebreather into account. If the
-pO<sub>2</sub> drops below what is considered a save value, a warning appears in the <em>Dive plan
-details</em>. A typical pSCR configuration is with a single cylinder and one or more bail-out
-cylinders. Therefore the setup of the <em>Available gases</em> and the <em>Dive planner points</em> tables
-are very similar to that of a CCR dive plan, described above. However, no oxygen setpoints
-are specified for pSCR dives. Below is a dive plan for a pSCR dive. The dive is comparable
-to that of the CCR dive above, but note the longer ascent duration due to the lower oxygen
-in the loop due to the oxygen drop across the mouthpiece of the pSCR equipment.</p></div>

-<div class="paragraph"><p>To plan a dive using a closed circuit rebreather, select the <em>CCR</em> option in
-the dropdown list, circled in blue in the image below.</p></div>
-<div class="paragraph"><p><strong>Available gases</strong>: In the <em>Available gases</em> table, enter the cylinder information for the
-diluent cylinder and for any bail-out cylinders. Do NOT enter the information for the oxygen
-cylinder since it is implied when the <em>CCR</em> dropdown selection is made.</p></div>
-<div class="paragraph"><p><strong>Entering setpoints</strong>: Specify a default setpoint in the Preferences tab, by selecting <em>File →  Preferences →  Graph</em> from the main menu. All user-entered segments in the <em>Dive planner points</em> table
-use the default setpoint value. Then, different setpoints can be specified for dive segments
-in the <em>Dive planner points</em> table. A zero setpoint
-means the diver bails out to open circuit mode for that segment. The decompression is always calculated
-using the setpoint of the last manually entered segment. So, to plan a bail out ascent for a
-CCR dive, add a one-minute dive segment to the end with a setpoint value of 0. The decompression
-algorithm does not switch deco-gases automatically while in CCR mode (i.e. when a positive setpoint is specified) but, of course, this is calculated for bail out ascents.</p></div>
-<div class="paragraph"><p>The dive profile for a CCR dive may look something like the image below.</p></div>

-<h3 id="S_Replan">13.5. Modifying an existing dive plan</h3>
-<div class="paragraph"><p>Normally, when a dive plan has been saved, it is accessible from the <strong>Dive
-List</strong>, like any other dive log. Within the <strong>Dive List</strong> there is not a way to
-change a saved dive plan.  To perform changes to a dive plan, select it on
-the <strong>Dive List</strong>. Then, in the main menu, select <em>Log → Re-plan dive</em>. This
-will open the selected dive plan within the dive planner, allowing changes
-to be made and saved as usual.</p></div>
-<div class="paragraph"><p>In addition there is the option "Save new". This keeps the original planned
-dive and adds a (possibly modified) copy to the dive list. If that copy is
-saved with the same start time as the original, the two dives are considered
-two versions of the same dive and do not influence other each during
-decompression calculation (see next section).</p></div>
-</div>
-<div class="sect2">
-<h3 id="_planning_for_repetitive_dives">13.6. Planning for repetitive dives</h3>
-<div class="paragraph"><p>Repetitive dives can easily be planned if the dates and start times of the
-repetitive dive set is specified appropriately in the top left-hand <em>Start
-Time</em> field. <em>Subsurface</em> calculates the gas loading figures correctly and
-the effect of the first dive is evaluated on later dives.</p></div>
-<div class="paragraph"><p>If one has just completed a long/deep dive and is planning another dive,
-then highlight, in the <strong>Dive List</strong>, the dive that has just been completed
-and then activate the planner. Depending on the start time of the planned
-dive, the planner takes into account the gas loading incurred during the
-completed dive and allows planning within these limitations.</p></div>
-<div class="paragraph"><p>If only a few standard configurations are used (e.g. in GUE), then a
-template dive can be created conforming to one of the configurations. If one
-now wishes to plan a dive using this configuration, just highlight the
-template dive in the <strong>Dive List</strong> and activate the planner: the planner takes
-into account the configuration in the highlighted dive.</p></div>
-</div>
-<div class="sect2">
-<h3 id="_printing_the_dive_plan">13.7. Printing the dive plan</h3>
-<div class="paragraph"><p>Selecting the <em>Print</em> button in the planner allows printing of the <em>Dive
-Plan Details</em> for wet notes. Alternatively one can cut and paste the <em>Dive
-Plan Details</em> for inclusion in a text file or word processing document.</p></div>
-<div class="paragraph"><p>Dive plans have many characteristics in common with dive logs (dive profile,
-dive notes, etc).  After a dive plan has been saved, the dive details and
-gas calculations are saved in the <strong>Notes</strong> tab. While a dive plan is being
-designed, it can be printed using the <em>Print</em> button in the dive
-planner. This prints the dive details and gas calculations in the <em>Dive Plan
-Details</em> panel of the dive planner. However, after the plan has been saved,
-it is represented in a way very similar to a dive log and the gas
-calculations cannot be accessed in the same way as during the planning
-process. The only way to print the dive plan is to use the <em>File → Print</em>
-facility on the main menu in the same way as for dive logs or by copy and
-paste to a word processor.</p></div>

-<h3 id="S_APPENDIX_F">20.1. Subsurface appears to miscalculate gas consumption and SAC</h3>
-<div class="paragraph" id="SAC_CALCULATION"><p><em>Question</em>: I dived with a 12.2 l tank, starting with 220 bar and ending
-with 100 bar, and I calculate a different SAC compared what <em>Subsurface</em>
-calculates. Is <em>Subsurface</em> miscalculating?</p></div>
-<div class="paragraph"><p><em>Answer</em>: Not really. What happens is that <em>Subsurface</em> actually calculates
-gas consumption differently - and better - than you expect.  In particular,
-it takes the incompressibility of the gas into account.  Traditionally, Gas
-consumption and SAC should be: <code>consumption = tank size x (start pressure -
-end pressure)</code></p></div>
-<div class="paragraph"><p>and that’s true for an ideal gas, and it’s what you get taught in dive
-theory.  But an "ideal gas" doesn’t actually exist, and real gases actually
-don’t compress linearly with pressure. Also, you are missing the fact that
-one atmosphere of pressure isn’t actually one bar.  So the <strong>real</strong>
-calculation is:</p></div>
-<div class="paragraph"><p><code>consumption = (amount_of_air_at_beginning - amount_of_air_at_end)</code></p></div>
-<div class="paragraph"><p>where the amount of air is <strong>not</strong> just "tank size times pressure in bar".
-It’s a combination of: "take compressibility into account" (which is a
-fairly small issue under 220 bar - you’ll see more differences when you do
-high-pressure tanks with 300bar) and "convert bar to atm" (which is the
-majority of your discrepancy).  Remember: one ATM is ~1.013 bar, so without
-the compressibility, your gas use is:</p></div>
-<div class="paragraph"><p><code>12.2*((220-100)/1.013)</code></p></div>
-<div class="paragraph"><p>which is about 1445, not 1464. So there was 19 l too much in your simple
-calculation that ignored the difference between 1 bar and one ATM.  The
-compressibility does show up above 200 bar, and takes that 1445 down about
-eight litres more, so you really did use only about 1437 l of air at surface
-pressure.</p></div>
-<div class="paragraph"><p>So be happy: your SAC really is better than your calculations indicated.  Or
-be sad: your cylinder contains less air than you thought it did.  And as
-mentioned, the "contains less air than you thought it did" really starts
-becoming much more noticeable at high pressure. A 400 bar really does not
-contain twice as much air as a 200 bar one. At lower pressures, air acts
-pretty much like an ideal gas.</p></div>

-<h3 id="_some_dive_profiles_have_time_discrepancies_with_the_recorded_samples_from_my_dive_computer_8230">20.2. Some dive profiles have time discrepancies with the recorded samples from my dive computer…</h3>
-<div class="paragraph"><p><em>Subsurface</em> ends up ignoring surface time for many things (average depth,
-divetime, SAC, etc).  <em>Question</em>: Why do dive durations in my dive computer
-differ from that given by <em>Subsurface</em>?</p></div>
-<div class="paragraph"><p><em>Answer</em>: For example, if you end up doing a weight check (deep enough to
-trigger the "dive started")  but then come back up and wait five minutes for
-your buddies, your dive computer may say that your dive is 50 minutes long -
-because you have fifty minutes worth of samples - but subsurface will say
-it’s 45 minutes - because you were actually diving for 45 minutes.  It’s
-even more noticeable if you do things like divemastering the initial OW
-dives, when you may stay in the water for a long time, but spend most of it
-at the surface. And then you don’t want that to count as some kind of long
-dive”.</p></div>

-<h3 id="_some_dive_profiles_are_missing_from_the_download">20.3. Some dive profiles are missing from the download</h3>
-<div class="paragraph" id="DC_HISTORY"><p><em>Question</em>: I cannot download all my dives, only the most recent ones even
-though my dive computer’s manual states that it records history of e.g. 999
-dives.</p></div>
-<div class="paragraph"><p><em>Answer</em>: Dive history is different than the dive profiles on the log.  The
-history only keeps track of the total number of dives and total amount of
-time spent below surface. The logs, on the other hand, store the dive
-profile, but they have limited amount of memory to do so. The exact amount
-of dive profiles that can be stored on the device depend on sample interval
-and duration of the dives. Once the memory is full the oldest dives get
-overwritten with new dives. Thus we are only able to download the last 13,
-30 or 199 dives.</p></div>
-<div class="paragraph"><p>If you have downloaded your dives to different dive logging software before
-they were overwritten, there is a high chance that Subsurface can import
-these. However, if the logs are only on your dive computer, they cannot be
-salvaged after being over written by new dives.</p></div>

+from both dive computers to the same <em>Subsurface</em> computer, then one would

+Suunto D4". Alternatively, consider a technical diver dives with two or more
+dive computers of the same model, the logs of both (or all) being uploaded.
+In this case it might be prudent to call one of them "Suunto D4 (1)" and

+items of information in the <strong>Notes</strong> tab (e.g. water temperature) and in the
+<strong>Equipment</strong> tab (e.g. gas pressures and gas composition). However the other
+fields remain empty.  It may be useful to simultaneously edit some of the
+fields in the <strong>Notes</strong> and <strong>Equipment</strong> tabs.  For instance, it is possible
+that a diver performed several dives during a single day, using identical
+equipment while diving at the same dive site or with the same dive master
+and/or buddy or tags. Instead of completing the information for each of
+these dives separately, one can select all the dives for that day in the
+<strong>Dive List</strong> and insert the same information in the <strong>Notes</strong> and <strong>Equipment</strong>
+fields that need identical information. This is achieved by editing the dive
+notes or the equipment for any one of the selected dives.</p></div>
+<div class="paragraph"><p>The simultaneous editing only works with fields that do not already contain
+information.  This means that, if some fields have been edited for a
+particular dive among the selected dives, these are not changed while
+editing the dives simultaneously. Technically, the rule for editing several
+dives simultaneously is: if the data field being edited contains <em>exactly
+the same information</em> for all the dives that have been selected, the new,
+edited information is substituted for all the selected dives, otherwise only
+the edited dive is changed, even though several dives have been selected in
+the <strong>Dive List</strong>. This greatly speeds up the completion of the dive log after
+several similar dives.</p></div>
+<div class="paragraph" id="S_CopyComponents"><p><em>METHOD 2</em>:There is a different way of achieving the same goal. Select a
+dive with all the appropriate information typed into the <strong>Notes</strong> and

+components</em>.  A box is presented with a selection of check boxes for most of
+the fields in the <strong>Notes</strong> and <strong>Equipment</strong> tabs.  Select the fields to be
+copied from the currently selected dive, then select <em>OK</em>. Now, in the <strong>Dive

+<div class="paragraph" id="S_ImportingAlienDiveLogs"><p>If a user has been diving for some time, it is possible that several dives

+log software. While some software is supported natively, for others the user
+has to export the logbook(s) to an intermediate format so that they can then
+be imported by <em>Subsurface</em>.  Currently, <em>Subsurface</em> supports importing CSV
+log files from several sources.  APD LogViewer, XP5, Sensus and Seabear
+files are preconfigured, but because the import is flexible, users can
+configure their own imports.  Manually kept log files (e.g. a spreadsheet)
+can also be imported by configuring the CSV import.  <em>Subsurface</em> can also
+import UDDF and UDCF files used by some divelog software and some dive
+computers, like the Heinrichs & Weikamp DR5. Finally, for some divelog
+software like Mares Dive Organiser it is currently suggested to import the
+logbooks first into a webservice like <em>divelogs.de</em> and then import them
+from there with <em>Subsurface</em>, as divelogs.de supports a few additional

+<em>Subsurface</em> tries to detect multiple records for the same dive and merges
+the information as best as it can. If there are no time zone issues (or

+   dive duration, names of buddy and dive master and perhaps some information
+   about cylinder pressures before and after the dive, as well as a comment or

+<em>CSV dive profile</em>: This dive log format includes much more information

+   intervals, indicating depth, water temperature at that depth, and cylinder
+   pressure at that moment in time. Each line contains the information for a
+   single instant in time during the dive, 30 seconds after that of the
+   previous instant. Many lines are required to complete the depth profile

+<div class="paragraph"><p>Before being able to import the <em>CSV</em> data to <em>Subsurface</em> <strong>one needs to
+know a few things about the data being imported</strong>:</p></div>
+<div class="olist loweralpha"><ol class="loweralpha">
+<li>
+<p>
+Which character separates the different columns within a single line of
+   data? This field separator should be either a comma (,) a semicolon (;) or a
+   TAB character.  This can be determined by opening the file with a text
+   editor. If it is comma-delimited or semicolon-delimited, the comma or
+   semicolon characters between the values are clearly visible. If these are
+   not evident and the numbers are aligned in columns, the file is probably
+   TAB-delimited (i.e. it uses a TAB as a field separator).
+</p>
+</li>
+<li>
+<p>
+Which data columns need to be imported into <em>Subsurface</em>? Is it a <em>CSV dive
+   details</em> file or a <em>CSV dive profile</em> file? Open the file using a text
+   editor and note the titles of the columns to be imported and their column
+   positions.
+</p>
+</li>
+<li>
+<p>
+Is the numeric information (e.g. dive depth) in metric or in imperial units?
+</p>
+</li>
+</ol></div>
+<div class="paragraph"><p>Armed with this information, importing the data into <em>Subsurface</em> is
+straightforward. Select <em>Import → Import Log Files</em> from the main menu. In
+the resulting file selection menu, select <em>CSV files</em> (towards the bottom
+right). This shows all .CSV files in the selected directory. Select the file
+that needs to be imported. A configuration panel appears as depicted below:</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="images/csv_import1_f20.jpg" alt="FIGURE: CSV download dialogue 1" />
+</div>
+</div>
+<div class="paragraph"><p>Notice that, at the top left, there is a dropdown list containing
+pre-configured settings for some of the more common dive computers and
+software packages encountered by divers. If the <em>CSV</em> file being imported
+originated from any of these pre-configured items, then select it. Otherwise
+use the <em>Manual Import</em> option. The configuration panel also has dropdown
+lists for the specification of the appropriate field separator (Tab, comma
+or semicolon), the date format used in the <em>CSV</em> file, the time units
+(seconds, minutes or minutes:seconds), as well as the unit system (metric or
+imperial). Selecting the appropriate options among these is critical for the
+successful import of the data.</p></div>
+<div class="paragraph"><p>The last remaining task is to ensure that all the data columns have the
+appropriate column headings. The top blue row of the data table contains the
+column headings found in the <em>CSV</em> data file. The blue row of balloons
+immediately above these contains the names understood by <em>Subsurface</em>. These
+balloons can be moved using a drag-and-drop action. For instance,
+<em>Subsurface</em> expects the column heading for Dive number (" # ") to be "Dive
+# ". If the column heading that <em>Subsurface</em> expects is not in the blue row,
+then drag the appropriate balloon from the upper area and drop it in the
+appropriate blue cell at the top of the table. To indicate the correct
+column for "Dive #", drag the ballooned item labelled "Dive # " and drop it
+in the blue cell immediately above the white cell containing " # ". This is
+depicted in the image below.</p></div>

+of cells correspond to the headings listed in the top part of the

+<td class="content"><em>CSV</em> is an abbreviation for a data file format: <em>Comma-Separated
+Values</em>. It is a file format allowing someone to view or edit the
+information using a text editor such as Notepad (Windows), gedit (Linux) or
+TextWrangler (OS/X). The two main advantages of the <em>CSV</em> format is that the
+data are easily editable as text without any proprietary software and
+ensuring all information is human-readable, not being obscured by any custom
+or proprietary attributes that proprietary software insert into files.
+Because of its simplicity the <em>CSV</em> format is used as an interchange format
+between many software packages, e.g. between spreadsheet, statistical,
+graphics, database and diving software. Within <em>Subsurface</em>, <em>CSV</em> files can
+also be used to import information from other sources such as
+spreadsheet-based dive logs and even from some dive computers.</td>

+<div class="paragraph"><p><em>CSV</em> files can be created or edited with a normal text editor. The most
+important attribute of a <em>CSV</em> file is the <em>field separator</em>, the character
+used to separate fields within a single line. The field separator is
+frequently a comma, a colon, a SPACE character or a TAB character. When
+exporting data from spreadsheet software, the field separator needs to be
+specified in order to create the <em>CSV</em> file. <em>CSV</em> files are normally
+organised into a single line that provides the headers (or <em>field names</em>) of
+the data columns, followed by the data, one record per line. Note that each
+field name may comprise more than one word separated by spaces; for instance
+<em>Dive site</em>, below. Here is an example of dive information for four dives

+<div class="paragraph"><p>This brings up the time synchronisation dialog, shown below. The critical
+problem is that the time synchronisation is not perfect between the dive
+computer used during a dive, and the camera used during that same
+dive. These two devices often differ by several minutes. If <em>Subsurface</em> can
+achieve synchronisation, then the exact times of photographs can be used to
+position photographs on the dive profile.</p></div>
+<div class="paragraph"><p><em>Subsurface</em> achieves this synchronisation in three ways:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+<strong>Pro-actively</strong>: Before the dive, ensure synchronisation of the dive computer time settings with
+  the time settings of the camera by changing the date-time settings on one or both of these devices.
+</p>
+</li>
+<li>
+<p>
+<strong>Manually</strong>: If the user wrote down the exact camera time at the start of a dive, the
+  difference in time between the two devices can be determined. Actually, as long as the device
+  settings for time has not been changed in either device, one could write down the times of
+  both devices after the dive or even at the end of the day. One can then manually set the time
+  difference in the <em>Time shift</em> dialog. Towards the top of the dialog is a time setting tool
+  immediately under the heading <em>Shift times of image(s) by</em>, evident in figure <strong>A</strong> below.
+  If the camera time is 7 minutes later than that of the dive computer, set the time setting
+  tool to a value of 00:07.  Select either the <em>earlier</em> or <em>later</em> radio button.
+  In the above example, the <em>earlier</em> option is appropriate, since the photos need to be shifted
+  7 minutes earlier (camera is 7 minutes ahead of dive computer). Ignore any "AM" or "PM" suffix
+  in that tool. Click the <em>OK</em> button and synchronisation is achieved.

+</div>
+</div>
+<div class="ulist"><ul>
+<li>
+<p>
+<strong>By photograph</strong>: There is a very slick way of achieving synchronisation. If one takes a
+  photograph of the face of the dive computer showing the time, then <em>Subsurface</em> can obtain
+  the exact time the photograph was taken, using the metadata that the camera stores within
+  each photo. In order to do this, use the bottom half of the <em>Time shift</em> dialog. If one uses
+  the bottom part, the top part of the dialog is ignored. Click on
+  the horizontal bar entitled "<em>Select image of dive computer showing time</em>. This brings up
+  a file browser with which one can select the photograph of the dive computer time. Select the
+  photograph using the file browser and click on <em>OK</em>. This photograph of the dive computer
+  appears in the bottom panel of the <em>Shift times</em> dialog. Now <em>Subsurface</em> knows exactly
+  when the photograph has been taken. Now set the date-time dialog to the left of the photo
+  so that this tool reflects the date and time of the dive computer in the photo. When the
+  date-time tool has been set, <em>Subsurface</em> knows exactly what the time difference between
+  camera and dive computer is, and synchronisation is achieved.

+needs more than one gas mixture because of the depth or the decompression
+needs of the dive. For this reason multi-cylinder dives are often used by
+technical divers who dive deep or long. As far as <em>Subsurface</em> is concerned,
+there are only two types of information that need to be provided:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+<strong>Describe the cylinders used during the dive</strong> This is performed in the <strong>Equipment tab</strong> of
+  the <strong>Info</strong> panel, as <a href="#cylinder_definitions">described above</a>. Enter the cylinders one by one,
+  specifying the characteristics of the cylinder and the gas composition within each cylinder.

+<strong>Record the times at which switches from one cylinder to another was done:</strong> This is information
+  provided by some dive computers (provided the diver indicated these changes to the dive computer
+  by pressing specific buttons). If the dive computer does not provide the information, the diver has to
+  record these changes using a different method, e.g. writing it on a slate.
+</p>
+</li>
+<li>
+<p>
+<strong>Record the cylinder changes on the dive profile</strong>: If the latter option
+  was followed, the diver needs to indicate the gas change event by right-clicking at the appropriate point

+configuration for cave divers, sidemount diving can be performed by
+recreational divers who have completed the appropriate training. Sidemount
+dive logging involves, exactly as with multi-cylinder dives, above, three
+steps:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+<strong>During the dive, record cylinder switch events</strong>. Since sidemount diving normally involves two
+  cylinders with air or with the same gas mixture, <em>Subsurface</em> distinguishes among these different
+  cylinders. In contrast, many dive computers that allow gas switching only distinguish among different
+  <em>gases</em> used, not among different <em>cylinders</em> used. This means that when sidemount dives are downloaded
+  from these dive computers, the events of switching between cylinders with the same gas are not downloaded. This may mean
+  that one may have to keep a written log of cylinder switch times using a slate, or (if the dive computer
+  has this facility) marking each cylinder switch with a bookmark that can be retrieved later. Returning
+  from a dive with the times of cylinder changes is the only tricky part of logging sidemount dives.
+</p>
+</li>
+<li>
+<p>
+<strong>Within <em>Subsurface</em> describe the cylinders used during the dive</strong>. The diver needs to provide the
+  specifications of the different cylinders, using the <strong>Equipment</strong> tab of the <strong>Info Panel</strong> (see
+  image below where two 12 litre cylinder were used).
+</p>
+</li>
+<li>
+<p>
+<strong>Indicate cylinder change events on the <em>Subsurface</em> dive profile</strong>. Once the dive log has been imported
+  from a dive computer into <em>Subsurface</em>, the cylinder switch events need to be indicated on the dive profile.
+  Cylinder changes are recorded by right-clicking at the appropriate point on the dive profile and then
+  selecting <em>Add gas change</em>. A list of the appropriate cylinders is shown with the
+  currently used cylinder greyed out. In the image below Tank 1 is greyed out, leaving only Tank 2
+  to be selected. Select the appropriate cylinder. The cylinder change is then indicated on the dive

+ceilings arise when a direct ascent to the surface increases the risk of a
+diver suffering from decompression sickness (DCS) and it is necessary to
+either ascend slower or to perform decompression stop(s) before ascending to
+the surface. Not all dive computers record this information and make it
+available for download; for example all of the Suunto dive computers fail to
+make this very useful data available to divelog software. <em>Subsurface</em> also
+calculates ceilings independently, shown as a green overlay on the dive
+profile.  Because of the differences in algorithms used and amount of data
+available (and other factors taken into consideration at the time of the
+calculation) it is unlikely that ceilings from dive computers and from
+<em>Subsurface</em> are the same, even if the same algorithm and <em>gradient factors</em>
+(see below) are used.  It is also quite common that <em>Subsurface</em> calculates
+a ceiling for non-decompression dives when the dive computer stayed in
+non-deco mode during the whole dive (represented by the <span class="green">dark green</span>
+section in the profile at the beginning of this section). This is caused by
+the fact that <em>Subsurface’s</em> calculations describe the deco obligation at
+each moment during a dive, while dive computers usually take the upcoming
+ascent into account. During the ascent some excess nitrogen (and possibly
+helium) are already breathed off so even though the diver technically
+encountered a ceiling at depth, the dive still does not require an explicit
+deco stop. This feature allows dive computers to offer longer non-stop

+The light green area indicates the total gas, with the top margin of the
+  light green area indicating the total gas pressure inhaled by the diver and
+  measured from the bottom of the graph to the top of the light green
+  area. This pressure has a <em>relative</em> value in the graph and does not
+  indicate absolute pressure.
+</p>
+</li>
+<li>
+<p>
+The horizontal black line underneath the light green margin indicates the
+  equilibrium pressure of the inert gases inhaled by the diver, usually
+  nitrogen. In the case of trimix, it is the pressures of nitrogen and helium
+  combined. In this example, the user is diving with EAN32, so the inert gas
+  pressure is 68% of the distance from the bottom of the graph to the total
+  gas pressure value.
+</p>
+</li>
+<li>

+The dark green area at the bottom of the graph represents the pressures of

+</p>
+</li>
+<li>
+<p>
+Graph <strong>B</strong> indicates the situation after a descent to 30 meters. Few of the

+  pressures being far below the equilibrium gas pressure.
+</p>
+</li>
+<li>
+<p>
+Graph <strong>C</strong> represents the pressures after 30 minutes at 30 m. The fast
+  compartments have attained equilibrium (i.e. they have reached the hight of
+  the black line indicating the equilibrium pressure). The slower compartments
+  (towards the right) have not reached equilibrium and are in the process of
+  slowly increasing in pressure.
+</p>
+</li>
+<li>
+<p>
+Graph <strong>D</strong> shows the pressures after ascent to a depth of 4.5 meters. Since,
+  during ascent, the total inhaled gas pressure has decreased strongly from 4
+  bar to 1.45 bar, the pressures in the different tissue compartments now
+  exceed that of the total gas pressure and approaches the gradient factor
+  value (i.e.  the top black horizontal line). Further ascent will result in

+<li>
+<p>
+Graph <strong>E</strong> indicates the situation after remaining at 4.5 meters for 10
+  minutes. The fast compartments have decreased in pressure. As expected, the

+<h2 id="S_Cloud_access">9. Keeping a <em>Subsurface</em> dive log in the Cloud</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>For each diver, dive log information is highly important. Not only is it a
+record of diving activities for one’s own pleasure, but it is important
+information required for admission to further training courses or
+(sometimes) even diving sites. The security of the dive log is therefore
+critical. In order to have a dive log that is resistant to failure of a home
+computer hard drive, loss or theft of equipment, the Cloud is an obvious
+solution. This also has the added benefit that one can access one’s dive log
+from anywhere in the world without having to carry it with oneself. For this
+reason, facilities such as <em>divelogs.de</em> and <em>Diving Log</em> offer to store
+dive log information on the Internet.</p></div>
+<div class="paragraph"><p><em>Subsurface</em> includes access to a transparently integrated cloud storage
+back end that is available to all Subsurface users. Storing and retrieving a
+dive log from the cloud is no more difficult than accessing the dives on the
+local hard disk.  The only requirement is that one should first register as
+a user on the cloud.  To use <em>Subsurface cloud storage</em> , follow these
+steps:</p></div>
+<div class="sect2">
+<h3 id="_create_a_cloud_storage_account">9.1. Create a cloud storage account</h3>
+<div class="ulist"><ul>
+<li>
+<p>
+Open the <strong>Network Preferences</strong> by selecting <em>File</em> → <em>Preferences</em> → <em>Network</em>.
+</p>
+</li>
+<li>
+<p>
+In the section headed <em>Subsurface cloud storage</em>, enter an email address that
+   <em>Subsurface</em> can use for user registration.
+</p>
+</li>
+<li>
+<p>
+Enter a novel password that <em>Subsurface</em> will use to store the
+  dive log in the cloud.
+</p>
+</li>
+<li>
+<p>
+Click <em>Apply</em> to send the above email address and password to the
+  (remote) cloud server. The server responds by sending a verification PIN to
+  the above email address (This is the <strong>only</strong> occasion that <em>Subsurface</em> uses the
+  email address provided above). The <strong>Network Preferences</strong> dialog now has a new PIN text
+   box, not visible previously.
+</p>
+</li>
+<li>
+<p>
+Enter the PIN in the corresponding text box in the <strong>Network Preferences</strong> dialog
+(this field is only visible while the server is waiting for email
+address confirmation)
+</p>
+</li>
+<li>
+<p>
+Click <em>Apply</em> again. The <em>Subsurface cloud storage</em> account
+will be marked as verified and the <em>Subsurface cloud storage</em> service is initialised for use.

+<div class="sect2">
+<h3 id="_using_em_subsurface_cloud_storage_em">9.2. Using <em>Subsurface cloud storage</em></h3>
+<div class="ulist"><ul>
+<li>
+<p>
+Once the cloud storage has been initialised, two new items appear in the
+   <em>File</em> menu of the main menu system: <em>Open cloud storage</em> and <em>Save to cloud storage</em>.
+These options allow the user to load and save data to the <em>Subsurface
+cloud storage</em> server.
+</p>
+</li>
+<li>
+<p>
+In the <em>Defaults Preferences</em> tab, one can select to use the <em>Subsurface cloud
+storage</em> data as one’s default data file by checking the check box marked <em>Cloud storage default file</em>.
+ This means that the data from
+the <em>Subsurface cloud storage</em> is loaded when <em>Subsurface</em> starts ans saved there when one closes <em>Subsurface</em>.
+</p>
+</li>
+<li>
+<p>
+<em>Subsurface</em> keeps a local copy of the data and the cloud facility remains fully
+functional even if used while disconnected to the Internet. <em>Subsurface</em> simply synchronises the
+data with the cloud server the next time ithe program is used while the computer is
+connected to the Internet.

+<div class="sect2">
+<h3 id="S_Cloud_storage">9.3. Web access to <em>Subsurface cloud storage</em></h3>
+<div class="paragraph"><p>One of the nice side benefits of using <em>Subsurface cloud storage</em> is that
+one can also access one’s dive data from any web browser. Simply open
+<a href="https://cloud.subsurface-divelog.org"><em>https://cloud.subsurface-divelog.org</em></a>,
+log in with the same email and password, and you can see an HTML export of
+the last dive data that was synced to the <em>Subsurface cloud storage</em>. The
+dive information that is shown is only the contents of the recorded dive

+<div class="sect2">
+<h3 id="_other_cloud_services">9.4. Other cloud services</h3>
+<div class="paragraph"><p>If one prefers not to use the integrated cloud storage of dive logs (and
+don’t need the web access), it is also simple to store dive logs in the
+cloud using several of the existing facilities on the Internet.  For
+instance <a href="http://www.dropbox.com/"><em>Dropbox</em></a> offers a free application that
+allows files on the Dropbox servers to be seen as a local folder on one’s
+desktop computer.</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="images/Cloud.jpg" alt="FIGURE: Dropbox folder" />
+</div>
+</div>
+<div class="paragraph"><p>The <em>Dropbox</em> program creates a copy of the <em>Dropbox</em> Internet Cloud content
+on one’s desktop computer. When the computer is connected to the Internet,
+the Internet content is automatically updated. Therefore both the <em>Open</em> and
+<em>Save</em> of dive logs are done using the local copy of the dive log in the
+local <em>Dropbox</em> folder, so there’s no need for a direct internet
+connection. If the local copy is modified, e.g. by adding a dive, the remote
+copy in the <em>Dropbox</em> server in the Cloud will be automatically updated
+whenever Internet access is available.</p></div>
+<div class="paragraph"><p>In this way a dive log in one’s <em>Dropbox</em> folder can be accessed seamlessly
+from the Internet and can be accessed from any place with Internet
+access. Currently there are no costs involved for this service. Dropbox
+(Windows, Mac and Linux) can be installed by accessing the
+<a href="http://www.dropbox.com/install"><em>Install Page on the Dropbox website</em></a>
+Alternatively one can use <em>Dropbox</em> as a mechanism to backup one’s dive
+log. To Store a dive log on <em>Dropbox</em>, select <em>File → Save as</em> from the
+<em>Subsurface</em> main menu, navigate to the <em>Dropbox</em> folder and select the
+<em>Save</em> button. To access the dive log in <em>Dropbox</em>, select <em>File → Open
+Logbook</em> from the <em>Subsurface</em> main menu and navigate to the dive log file
+in the <em>Dropbox</em> folder and select the <em>Open</em> button.</p></div>
+<div class="paragraph"><p>Several paid services exist on the Internet (e.g. Google, Amazon) where the
+same process could be used for the Cloud-based storage of dive logs.</p></div>

+   the gradient factor at depth and GF_High is used just below the surface.
+   At intermediate depths gradient factors between GF_Low and GF_High are used.
+   Gradient factors add conservatism to the nitrogen exposure during a dive, in a
+   similar way that many dive computers have a conservatism setting. The lower
+   the value of a gradient factor, the more conservative the calculations are with
+   respect to nitrogen loading and the deeper the ascent ceilings are. Gradient
+   factors of 20/60 are considered conservative and values of 70/90 are considered
+   harsh. Checking the <strong>GFLow at max depth</strong> box causes GF_Low to be used at the

+<h4 id="_recreational_dives">13.2.1. Recreational dives</h4>
+<div class="paragraph"><p>Recreational mode is what comes closest to planning a dive based on the
+non-decompression limit (NDL).  It computes the maximal time a diver can
+stay at the current depth without incurring any mandatory decompression
+stops and without using more than the existing gas (minus a reserve). The
+planner automatically takes into account the nitrogen load incurred in
+previous dives. But conventional dive tables are also used in a way that can
+take into account previous dives. Why use a dive planner for recreational
+dives? Using recreational dive tables, the maximum depth of a dive is taken
+into account. However, few dives are undertaken at a constant depth
+corresponding to the maximum depth (i.e. a "square" dive profile). This
+means that dive tables overestimate the nitrogen load incurred during
+previous dives. The <em>Subsurface</em> dive planner calculates nitrogen load
+according to the real dive profiles of all uploaded previous dives, in a
+similar way as dive computers calculate nitrogen load during a dive. This
+means that the diver gets <em>credit</em> in terms of nitrogen loading for not
+remaining at maximum depth during previous dives, enabling planning of a
+longer subsequent dive. For the planner to work it is therefore crucial to
+upload all previous dives onto <em>Subsurface</em> before performing dive planning.</p></div>
+<div class="paragraph"><p>To plan a dive, the appropriate settings need to be defined.</p></div>
+<div class="paragraph"><p>Ensure that the date and time is set to that of the intended dive. This
+allows calculation of the nitrogen load incurred during previous dives.</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+Immediately under the heading <em>Planning</em> are two checkboxes <em>Recreational</em>
+  and <em>Safety Stop</em>.  Check these two boxes.
+</p>
+</li>
+<li>
+<p>
+Then define the cylinder size, the gas mixture (air or % oxygen) and the
+  starting cylinder pressure in the top left-hand section of the planner under
+  <em>Available gases</em>.
+</p>
+</li>
+<li>
+<p>
+The planner calculates whether the specified cylinder contains enough
+  air/gas to complete the planned dive. In order for this to be realistic,
+  under <em>Gas options</em>, specify an appropriate surface air consumption (SAC)
+  rate for <em>Bottom SAC</em>. Suitable values are between 15 l/min and 30 l/min,
+  with novice divers or difficult dives requiring SAC rates closer to 30l/min.
+</p>
+</li>
+<li>
+<p>
+Define the amount of gas that the cylinder must have at the end of the
+  bottom section of the dive just before ascent. A value of 50 bar is often
+  used. The reason for this reserve gas is to provide for the possible need
+  need to bring one’s buddy to the surface using gas sharing. How much gas is
+  used in sharing depends on the depth of the ascent. This can be a bit hard
+  to estimate, so most agencies assume a fixed amount of gas, or actually of
+  pressure e.g. 40 or 50 bar or 25% or 33% (rule of thirds). But <em>Subsurface</em>
+  can do better because it knows about the ascent and that is why we add the
+  amount of gas during the ascent (i.e. the "deco gas“).  Subsurface still
+  uses a fixed pressure „reserve“ but that is supposed to be for the
+  additional gas used around the realisation that there is a problem and one’s
+  pulse rate goes up when one starts to buddy breathe. This reserve amount is
+  user configurable.
+</p>
+</li>
+<li>
+<p>
+Define the depth of the dive by dragging the waypoints (white dots) on the
+  dive profile or (even better) defining the appropriate depths using the
+  table under <em>Dive planner points</em> as desribed under the previous heading. If
+  this is a multilevel dive, set the appropriate dive depths to represent the
+  dive plan by adding waypoints to the dive profile or by adding appropriate
+  dive planner points to the <em>Dive Planner Points</em> table. <em>Subsurface</em> will
+  automatically extend the bottom section of the dive to the maximum duration
+  within the no-decompression limits (NDL).
+</p>
+</li>
+<li>
+<p>
+The ascent speed can be changed. The default ascent speeds are those
+  considered safe for recreational divers.
+</p>
+</li>
+</ul></div>
+<div class="paragraph"><p>The dive profile in the planner indicates the maximum dive time within
+no-deco limits using the Bühlmann ZH-L16 algorithm and the gas and depth
+settings specified as described above. The <em>Subsurface</em> planner allows rapid
+assessment of dive duration as a function of dive depth, given the nitrogen
+load incurred during previous dives. The dive plan includes estimates of the
+amount of air/gas used, depending on the cylinder settings specified under
+<em>Available gases</em>. If the initial cylinder pressure is set to 0, the dive
+duration shown is the true no-deco limit (NDL) without taking into account
+gas used during the dive. If the surface above the dive profile is RED it
+means that recreational dive limits are exceeded and either the dive
+duration or the dive depth needs to be reduced.</p></div>
+<div class="paragraph"><p>Below is an image of a dive plan for a recreational dive at 30

+<h4 id="_non_recreational_open_circuit_dives_including_decompression">13.2.2. Non-recreational open circuit dives, including decompression</h4>
+<div class="paragraph"><p>Non-recreational dive planning involves exceeding the no-deco limits and/or
+using multiple breathing gases.  Such dives are planned in three stages:</p></div>
+<div class="paragraph"><p><strong>a) Nitrogen management</strong>: This is performed by specifying the rates for descent and ascent,
+as well as the deco model (GFLow, GFHigh or Conservatism level) under the headings <em>Rates</em> and <em>Planning</em>
+to the bottom left of the planning screen. Two deco models are supported the Bühlmann model and the VPM-B
+model. Select one of the two models. When selecting the Bühlmann model, the gradient factors (GF_high and GF_low
+need to be specified. Initially, the GFHigh and GFLow values in the <em>Preferences</em>
+panel of <em>Subsurface</em> is used. If these are changed within the planner (see <em>Gas Options</em> within
+the planner), the new values are
+used without changing the original values in the <em>Preferences</em>. Gradient Factor settings strongly affect the calculated ceilings and their depths.
+A very low GFLow value brings about decompression stops early on during the dive.
+ ** For more information about Gradient factors, see the section on <a href="#S_GradientFactors">Gradient Factor Preference settings</a>.</p></div>
+<div class="paragraph"><p>If the VPM-B model is selected, the Conservatism_level needs to be specified
+on a scale of 0 (least conservative) to 4 (most conservative).  This model
+tends to give deco stops at deeper levels than the Bühlmann model and often
+results in slightly shorter dive durations than the Bühlmann model. When
+selecting one of these models, keep in mind that they are NOT exact
+physiological models but only mathematical models that appear to work in
+practice.</p></div>

+</ul></div>
+<div class="paragraph"><p>The ascent rate is critical for nitrogen off-gassing at the end of the dive
+and is specified for several depth ranges, utilising the average (or mean)
+depth as a yardstick. The mean depth of the dive plan is indicated by a
+light grey line on the dive profile. Ascent rates at deeper levels are often
+in the range of 8-12 m/min, while ascent rates near the surface are often in
+the range of 4-9 m/min. The descent rate is also specified. If the option
+<em>Drop to first depth</em> is activated, then the descent phase of the planned
+dive will be at the maximal descent rate specified in the <em>Rates</em> section of
+the dive setup.</p></div>
+<div class="paragraph"><p><strong>b) Oxygen management</strong>: In the <strong>Gas Options</strong> part of the dive specification, the maximum partial
+pressure for oxygen needs to be specified for the
+bottom part of the dive (<em>bottom po2</em>) as well as for the decompression part of the dive (<em>deco po2</em>).
+The most commonly
+used values are 1.4 bar for the bottom part of the dive and 1.6 bar for any decompression
+stages. Normally, a partial pressure of 1.6 bar is not exceeded. PO2 settings and the depth at which switching to a gas takes place can also be edited in the
+<em>Available Gases</em> dialog. Normally the planner decides on switching to a new gas when, during
+ascent, the partial pressure of the new gas has increased to 1.6 bar.</p></div>
+<div class="paragraph"><p><strong>c) Gas management</strong>: With open-circuit dives this is a primary consideration. One needs to keep within the limits of the amount of gas within the dive
+cylinder(s), allowing for an appropriate margin for a safe return to the surface, possibly
+sharing with a buddy. Under the <em>Gas Options</em> heading, specify the best (but conservative) estimate
+of your surface-equivalent air consumption (SAC, also termed RMV) in
+litres/min (for the time being, only SI units are supported).  Specify the SAC during the
+bottom part of the dive (<em>bottom SAC</em>) as well as during the decompression or safety stops of the
+dive (<em>deco SAC</em>). Values of 15-30 l/min are common. For good gas management, a thumbsuck guess
+is not sufficient and one needs to
+monitor one’s gas consumption on a regular basis, dependent on different dive conditions and/or equipment.
+The planner calculates the total volume of gas used during the dive and issues a warning
+if one exceeds the total amount of gas available. Good practice demands that one does not dive to
+the limit of the gas supply but that an appropriate reserve is kept for unforeseen circumstances.
+For technical diving, this reserve can be up to 66% of the total available gas.</p></div>
+<div class="paragraph"><p>Now (at last) one can start the detailed time-depth planning of the
+dive. <em>Subsurface</em> offers a unique graphical interface for performing this
+part of the planning. The mechanics of doing this is similar to
+hand-entering a dive profile in the dive log part of <em>Subsurface</em>. Upon
+activating the planner, a default dive of depth 15 m for 40 min is offered
+in the bue design surface to the top right hand of the screen. The white
+dots (waypoints) on the profile can be dragged with a mouse. Create more
+waypoints by double-clicking on the profile line and ensuring that the
+profile reflects the intended dive. Drag the waypoints to represent the
+depth and duration of the dive. It is NOT necessary to specify the ascent
+part of the dive since the planner calculates this, based on the settings
+that have been specified.  If any of the management limits (for nitrogen,
+oxygen or gas) is exceeded, the surface above the dive profile changes from
+BLUE to RED.</p></div>
+<div class="paragraph"><p>Each waypoint on the dive profile creates a <em>Dive Planner Point</em> in the
+table on the left of the dive planner panel. Ensure that the <em>Used Gas</em>
+value in each row of that table corresponds to one of the gas mixtures
+specified in the <em>Available Gases</em> table.  Add new waypoints until the main
+features of the dive have been completed, e.g. the bottom time segment and
+deep stops (if these are implemented). Leave the remaining waypoints on the
+ascent to <em>Subsurface</em>. In most cases <em>Subsurface</em> computes additional way
+points in order to fulfil decompression requirements for that dive. A
+waypoint can be moved by selecting that waypoint and by using the arrow
+keys.  The waypoints listed in the <em>Dive Planner Points</em> dialogue can be
+edited by hand in order to obtain a precise presentation of the dive
+plan. In fact, one can create the whole dive profile by editing the <em>Dive
+Planner Points</em> dialog.</p></div>
+<div class="paragraph"><p>Indicate any changes in gas cylinder used by indicating gas changes as
+explained in the section <a href="#S_CreateProfile">hand-creating a dive profile</a>. These changes should reflect the cylinders and gas compositions
+defined in the table with <em>Available Gases</em>.  If two or more gases are used,
+automatic gas switches will be suggested during the ascent to the
+surface. However, these changes can be deleted by right-clicking the gas
+change and by manually creating a gas change by right-clicking on the
+appropriate waypoint.</p></div>
+<div class="paragraph"><p>A non-zero value in the "CC set point" column of the table of dive planner
+points indicates a valid setpoint for oxygen partial pressure and that the
+segment is dived using a closed circuit rebreather (CCR). If the last
+manually entered segment is a CCR segment, the decompression phase is
+computed assuming the diver uses a CCR with the specified set-point. If the
+last segment (however short) is on open circuit (OC, indicated by a zero
+set-point) the decompression is computed in OC mode. The planner only
+considers gas changes in OC mode.</p></div>

+details</em>. A typical pSCR configuration is with a single cylinder and one or more bail-out
+cylinders. Therefore the setup of the <em>Available gases</em> and the <em>Dive planner points</em> tables
+are very similar to that of a CCR dive plan, described below. However, no oxygen setpoints
+are specified for pSCR dives. Below is a dive plan for a pSCR dive. The dive is comparable
+to that of the CCR dive below, but note the longer ascent duration due to the lower oxygen
+in the loop due to the oxygen drop across the mouthpiece of the pSCR equipment.</p></div>

+<div class="paragraph"><p>To plan a dive using a closed circuit rebreather, select the <em>CCR</em> option in
+the dropdown list, circled in blue in the image below.</p></div>
+<div class="paragraph"><p><strong>Available gases</strong>: In the <em>Available gases</em> table, enter the cylinder information for the
+diluent cylinder and for any bail-out cylinders. Do NOT enter the information for the oxygen
+cylinder since it is implied when the <em>CCR</em> dropdown selection is made.</p></div>
+<div class="paragraph"><p><strong>Entering setpoints</strong>: Specify a default setpoint in the Preferences tab, by selecting <em>File →  Preferences →  Graph</em> from
+the main menu. All user-entered segments in the <em>Dive planner points</em> table
+use the default setpoint value. Then, different setpoints can be specified for dive segments
+in the <em>Dive planner points</em> table. A zero setpoint
+means the diver bails out to open circuit mode for that segment. The decompression is always calculated
+using the setpoint of the last manually entered segment. So, to plan a bail out ascent for a
+CCR dive, add a one-minute dive segment to the end with a setpoint value of 0. The decompression
+algorithm does not switch deco-gases automatically while in CCR mode (i.e. when a positive setpoint is specified) but,
+of course, this is calculated for bail out ascents.</p></div>
+<div class="paragraph"><p>The dive profile for a CCR dive may look something like the image below.</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="images/Planner_CCR1_f20.jpg" alt="FIGURE: Planning a CCR dive: setup" />
+</div>
+</div>
+<div class="paragraph"><p>Note that, in the <em>Dive plan details</em>, the gas consumption for a CCR segment
+is not calculated, so gas consumptions of 0 litres are the norm.</p></div>
+</div>
+<div class="sect2">
+<h3 id="S_Replan">13.5. Modifying an existing dive plan</h3>
+<div class="paragraph"><p>Normally, when a dive plan has been saved, it is accessible from the <strong>Dive
+List</strong>, like any other dive log. Within the <strong>Dive List</strong> there is not a way to
+change a saved dive plan.  To perform changes to a dive plan, select it on
+the <strong>Dive List</strong>. Then, in the main menu, select <em>Log → Re-plan dive</em>. This
+will open the selected dive plan within the dive planner, allowing changes
+to be made and saved as usual.</p></div>
+<div class="paragraph"><p>In addition there is the option "Save new". This keeps the original planned
+dive and adds a (possibly modified) copy to the dive list. If that copy is
+saved with the same start time as the original, the two dives are considered
+two versions of the same dive and do not influence other each during
+decompression calculation (see next section).</p></div>
+</div>
+<div class="sect2">
+<h3 id="_planning_for_repetitive_dives">13.6. Planning for repetitive dives</h3>
+<div class="paragraph"><p>Repetitive dives can easily be planned if the dates and start times of the
+repetitive dive set is specified appropriately in the top left-hand <em>Start
+Time</em> field. <em>Subsurface</em> calculates the gas loading figures correctly and
+the effect of the first dive is evaluated on later dives.</p></div>
+<div class="paragraph"><p>If one has just completed a long/deep dive and is planning another dive,
+then highlight, in the <strong>Dive List</strong>, the dive that has just been completed
+and then activate the planner. Depending on the start time of the planned
+dive, the planner takes into account the gas loading incurred during the
+completed dive and allows planning within these limitations.</p></div>
+<div class="paragraph"><p>If only a few standard configurations are used (e.g. in GUE), then a
+template dive can be created conforming to one of the configurations. If one
+now wishes to plan a dive using this configuration, just highlight the
+template dive in the <strong>Dive List</strong> and activate the planner: the planner takes
+into account the configuration in the highlighted dive.</p></div>
+</div>
+<div class="sect2">
+<h3 id="_printing_the_dive_plan">13.7. Printing the dive plan</h3>
+<div class="paragraph"><p>Selecting the <em>Print</em> button in the planner allows printing of the <em>Dive
+Plan Details</em> for wet notes. Alternatively one can cut and paste the <em>Dive
+Plan Details</em> for inclusion in a text file or word processing document.</p></div>
+<div class="paragraph"><p>Dive plans have many characteristics in common with dive logs (dive profile,
+dive notes, etc).  After a dive plan has been saved, the dive details and
+gas calculations are saved in the <strong>Notes</strong> tab. While a dive plan is being
+designed, it can be printed using the <em>Print</em> button in the dive
+planner. This prints the dive details and gas calculations in the <em>Dive Plan
+Details</em> panel of the dive planner. However, after the plan has been saved,
+it is represented in a way very similar to a dive log and the gas
+calculations cannot be accessed in the same way as during the planning
+process. The only way to print the dive plan is to use the <em>File → Print</em>
+facility on the main menu in the same way as for dive logs or by copy and
+paste to a word processor.</p></div>

+<h3 id="S_APPENDIX_F">20.1. Subsurface appears to miscalculate gas consumption and SAC</h3>
+<div class="paragraph" id="SAC_CALCULATION"><p><em>Question</em>: I dived with a 12.2 l tank, starting with 220 bar and ending
+with 100 bar, and I calculate a different SAC compared what <em>Subsurface</em>
+calculates. Is <em>Subsurface</em> miscalculating?</p></div>
+<div class="paragraph"><p><em>Answer</em>: Not really. What happens is that <em>Subsurface</em> actually calculates
+gas consumption differently - and better - than you expect.  In particular,
+it takes the incompressibility of the gas into account.  Traditionally, Gas
+consumption and SAC should be: <code>consumption = tank size x (start pressure -
+end pressure)</code></p></div>
+<div class="paragraph"><p>and that’s true for an ideal gas, and it’s what you get taught in dive
+theory.  But an "ideal gas" doesn’t actually exist, and real gases actually
+don’t compress linearly with pressure. Also, you are missing the fact that
+one atmosphere of pressure isn’t actually one bar.  So the <strong>real</strong>
+calculation is:</p></div>
+<div class="paragraph"><p><code>consumption = (amount_of_air_at_beginning - amount_of_air_at_end)</code></p></div>
+<div class="paragraph"><p>where the amount of air is <strong>not</strong> just "tank size times pressure in bar".
+It’s a combination of: "take compressibility into account" (which is a
+fairly small issue under 220 bar - you’ll see more differences when you do
+high-pressure tanks with 300bar) and "convert bar to atm" (which is the
+majority of your discrepancy).  Remember: one ATM is ~1.013 bar, so without
+the compressibility, your gas use is:</p></div>
+<div class="paragraph"><p><code>12.2*((220-100)/1.013)</code></p></div>
+<div class="paragraph"><p>which is about 1445, not 1464. So there was 19 l too much in your simple
+calculation that ignored the difference between 1 bar and one ATM.  The
+compressibility does show up above 200 bar, and takes that 1445 down about
+eight litres more, so you really did use only about 1437 l of air at surface
+pressure.</p></div>
+<div class="paragraph"><p>So be happy: your SAC really is better than your calculations indicated.  Or
+be sad: your cylinder contains less air than you thought it did.  And as
+mentioned, the "contains less air than you thought it did" really starts
+becoming much more noticeable at high pressure. A 400 bar really does not
+contain twice as much air as a 200 bar one. At lower pressures, air acts
+pretty much like an ideal gas.</p></div>

+<div class="paragraph"><p><em>Subsurface</em> ends up ignoring surface time for many things (average depth,
+divetime, SAC, etc).  <em>Question</em>: Why do dive durations in my dive computer
+differ from that given by <em>Subsurface</em>?</p></div>
+<div class="paragraph"><p><em>Answer</em>: For example, if you end up doing a weight check (deep enough to
+trigger the "dive started")  but then come back up and wait five minutes for
+your buddies, your dive computer may say that your dive is 50 minutes long -
+because you have fifty minutes worth of samples - but subsurface will say
+it’s 45 minutes - because you were actually diving for 45 minutes.  It’s
+even more noticeable if you do things like divemastering the initial OW
+dives, when you may stay in the water for a long time, but spend most of it
+at the surface. And then you don’t want that to count as some kind of long
+dive”.</p></div>

+though my dive computer’s manual states that it records history of e.g. 999
+dives.</p></div>
+<div class="paragraph"><p><em>Answer</em>: Dive history is different than the dive profiles on the log.  The
+history only keeps track of the total number of dives and total amount of
+time spent below surface. The logs, on the other hand, store the dive
+profile, but they have limited amount of memory to do so. The exact amount
+of dive profiles that can be stored on the device depend on sample interval
+and duration of the dives. Once the memory is full the oldest dives get
+overwritten with new dives. Thus we are only able to download the last 13,
+30 or 199 dives.</p></div>
+<div class="paragraph"><p>If you have downloaded your dives to different dive logging software before
+they were overwritten, there is a high chance that Subsurface can import
