|
||
<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em>, an advanced dive logging programme with
|
||
extensive infrastructure to describe, organise, interpret and print scuba
|
||
and free dives. <em>Subsurface</em> offers many advantages above other similar
|
||
software solutions:</p></div>
|
||
<div class="ulist"><ul>
|

<li>
|
||
<p>
|
||
Do you use two different dive computer brands, each with its own proprietary
|
||
software for downloading dive logs? Do you dive with rebreathers as well
|
||
as open circuit? Do you use a Reefnet Sensus time-depth recorder
|
||
in conjunction with a dive computer? <em>Subsurface</em> offers a standard
|
||
interface for downloading dive logs from all these different pieces of
|
||
equipment and to store and analyse the dive logs within a unified system.
|
||
</p>
|
||
</li>
|
||
<li>
|
||
<p>
|
||
Do you use more than one operating system? <em>Subsurface</em> is fully compatible
|
||
with Mac, Linux and Microsoft, allowing you to access your dive log on each
|
||
of your operating systems in a unified way.
|
||
</p>
|
||
</li>
|
||
<li>
|
||
<p>
|
||
Do you use Linux or Mac and your dive computer has only Microsoft-based software
|
||
for downloading dive information (e.g. Mares)? <em>Subsurface</em> provides a way of
|
||
storing and anaysing your dive logs on other operating systems.
|
||
</p>
|
||
</li>
|
||
</ul></div>
|
||
<div class="paragraph"><p><em>Subsurface</em> binaries are available for Windows PCs (Win XP or later), Intel
|
||
based Macs (OS/X) and many Linux distributions. <em>Subsurface</em> can be built for
|
||
many more hardware platforms and software environments where Qt and
|
||
libdivecomputer are available.</p></div>
|

<div class="paragraph"><p>The scope of this document is the use of the <em>Subsurface</em> program. To install

the software, consult the <em>Downloads</em> page on the

<h3 id="S_EnterData">3.1. Entering dive information by hand</h3>
|

<div class="paragraph"><p>This is usually the approach for dives without a dive computer. The basic 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>Dive Notes</strong> and
|
||
<strong>Equipment</strong>), as well as the <strong>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

<div class="paragraph"><p>To import dive information from a dive computer to a computer with

<em>Subsurface</em>,
|
||
it is necessary that the two pieces of equipment communicate with one another.
|
||
This
|
||
involves setting up the communications port (or mount point) of the computer
|
||
with <em>Subsurface</em> that communicates with the dive computer. In order to set up
|
||
this communication, one needs to find the appropriate information to
|
||
instruct
|
||
<em>Subsurface</em> where and how to import the dive information.

<div class="paragraph"><p>Dive computers tend to keep a certain number of dives in their memory, even
|
||
though these dives have already been imported to <em>Subsurface</em>. For that reason
|
||
<em>Subsurface</em> only imports dives that have not been uploaded before. This makes
|
||
the download process faster on most dive computers and also saves battery power
|
||
of the dive computer (at least for those not charging while connected via USB).
|
||
If, for some reason, the user wishes to import ALL dives from the dive computer,
|

even though some may already be in the logbook, then check the the check box labeled

<strong>vendor</strong> drop-down list select the make of the computer, e.g.
|
||
Suunto, Oceanic,
|
||
Uwatec, Mares. On the <strong>Dive Computer</strong> drop-down list, the model name of
|

<li>
|

<p>
|

If all the dives on the dive computer need to be downloaded, check the
|
||
checkbox <em>Force download of all dives</em>. Normally, <em>Subsurface</em> only downloads
|
||
dives after the date-time of the last dive in the <strong>Dive List</strong> panel. If one
|
||
or more of your dives in <em>Subsurface</em> have been accidentally deleted or if there
|
||
are older dives that still need to be downloaded from the dive computer, this
|
||
checkbox needs to be activated. Some dive computers (e.g. Mares Puck) do not provide
|
||
a contents list to <em>Subsurface</em> before the download in order to select only new dives.
|
||
Consequently, for these dive computers, all dives are downloaded
|
||
irrespective of the status of this check box.
|
||
</p>
|
||
</li>
|
||
<li>
|

the dive computer and on the <em>Subsurface</em>
|

<strong>Dive List</strong> panel, the record in the <em>Subsurface</em> divelog will be overwritten

With communication established, one can see how the data are
|
||
retrieved from the dive computer.
|
||
Depending on the make of the dive computer and/or number of recorded dives, this
|
||
could take some time. The user should be patient. The <em>Download</em> dialogue
|
||
shows a
|
||
progress bar at the bottom of the dialogue (for some dive computers the
|
||
progress information could be inaccurate as we cannot determine how much
|
||
downloadable data there is until all data have been downloaded). When the
|
||
download of the dive information is complete, all the imported dives appear
|
||
in the <strong>Dive List</strong>, sorted by date and time. Disconnect and
|
||
switch off the dive
|

computer to conserve its battery power.
|

If a particular dive is selected, the <strong>Dive Profile</strong> panel shows an informative

<div class="paragraph" id="S_ImportingAlienDiveLogs"><p>If a user has been diving for some time, it is possible that several dives were
|
||
logged using other dive log software. This information does not need retyping
|
||
because these divelogs can probably be
|
||
imported onto <em>Subsurface</em>. <em>Subsurface</em> will import divelogs from a range of
|
||
other
|
||
dive 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 and Sensus files are
|
||
preconfigured, but because the import is flexible, users can configure their own
|
||
imports.
|
||
Manually kept log files (e.g. in 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 divecomputers, 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 logbook formats that
|
||
<em>Subsurface</em> currently cannot parse.</p></div>
|

<div class="paragraph"><p>When importing dives, <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 other reasons that would cause the

beginning time of the dives to be significantly different) <em>Subsurface</em>

a large difference between the time in the dive computer and that of the Android device,

resulting in no updates.</p></div>
|

<div class="paragraph"><p>Similar date-times may not always be possible and there may be many reasons for this (e.g. time zones), or

A workaround for this situation to manually edit the date-time of a dive in the <em>Subsurface</em>

precisely, the deepest deco stop that the dive computer calculated for each

particular moment in time) as a red overlay on the dive profile. Ascent 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 bottom times.</p></div>

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 button was initially clicked to bring up the menu. Gas Change events
|

open a further selection of which gas is being switched to, the list based on

the available gases defined in the Equipment Tab. By right-clicking while over
|

|
||
only the top line of the Information Box is visible (see left-hand part of
|
||
figure (<strong>A</strong>) below). The Information Box can be moved around in the <strong>Dive Profile</strong>
|

the dive profile indicated by the mouse cursor (see right-hand part of figure (<strong>B</strong>) above
|

where the Information Box reflects the situation at the position of the cursor
|

[arrow] in that image). Therefore, moving the cursor in the horizontal
|

direction allows the Information Box to show information for any point along the
|
||
dive profile.
|
||
In this mode, the Information Box gives extensive statistics about depth, gas
|
||
and ceiling characteristics of the particular dive. These include: Time period
|

into the dive (indicated by a @), depth, cylinder pressure (P), temperature,
|

ascent/descent rate, surface air consumption (SAC), oxygen partial pressure,
|
||
maximum operating depth, equivalent air depth (EAD), equivalent narcotic depth
|

Gas pressure graphs: <em>Subsurface</em> can display the nitrogen, oxygen and the helium partial pressures during

|

panel. For each of these graphs users can specify a threshold value on the right-hand side of the

<em>draw dive computer reported ceiling red</em>: This checkbox allows exactly what it says.
|
||
Not all dive computers report ceiling values. If the dive computer does report it, it may differ
|
||
from the ceilings calculated by Subsurface. This is because of the different algorithms and gradient factors available for calculating ceilings, as well as the dynamic way that a
|
||
dive computer can calculate ceilings during a dive.
|

</p>
|

</li>
|

<p>

<em>Show non-used cylinders in Equipment Tab</em>: This checkbox allows display of information about non-used cylinders when viewing the <strong>Equipment Tab</strong>. Conversely, if this box is un-checked, and any cylinders entered using the <strong>Equipment Tab</strong> are not used (e.g. there was no gas switch to such a cylinder), then these cylinders are omitted from that list.
|
||
</p>
|
||
</li>
|
||
<li>
|

<p>
|

<em>show average depth</em>: Activating this checkbox causes Subsurface to draw a red line across

|
||
<strong>Misc</strong>: <strong>Gradient Factors:</strong> Here users can set the <em>gradient factors</em> used while diving. GF_Low is
|
||
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 60/90 are considered
|
||
harsh. Checking <strong>GFLow at max depth</strong> box causes GF_Low to be used at the
|
||
deepest depth of a dive. For more information see:

On Linux users need to have the correct kernel

Things are very similar to a normal USB-connected dive computer

The main difference is that one does not enter a

mounted once connected to the dive computer. On Windows this is a drive letter (

dives without running out of memory on the SDA. This will usually only

happen the very first time one downloads dives from the Uemis Zurich.
|

Normally when downloading at the end of a day or even after a dive
|

trip, the capacity is sufficient. If <em>Subsurface</em> displays an error
|
||
that the dive computer ran out of space the solution is straight
|
||
forward. Disconnect the SDA, turn it off and on again, and reconnect

it. You can now retry (or start a new download session) and the

download will continue where it stopped previously. One

<h3 id="_subsurface_appears_to_miscalculate_gas_consumption_and_sac">13.1. 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 liters 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_discrepances_with_the_recorded_samples_from_my_dive_computer_8230">13.2. Some dive profiles have time discrepances 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).
|
||
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>
