Image B shows a gradient of unique colors, spanning the whole range of inert gas pressures. The list of choices is based on the available gases defined in the Equipment Tab. Only a subset of the dive data is exported: (int) unique dive ID, should be used to fetch the dive profile, (int) dive rating which ranges from 0 to 5, (string) complete information of all used cylinders, (string) information about a specific cylinder, (string) complete information of all used weight systems, (string) information about a specific weight system, (string) the summed weight of all used weight systems, (string) the salinity of the water for the dive, (string) the type of the water for the dive. For instance, most dive computers report alarms relating to high partial pressures of oxygen, to rapid ascents or the exceeding of no-deco limits (NDL). OSTC Tools downloads dive data from the dive computer and stores it as a binary file with file extension .dive . If you have an onboard controller, try that first. These buttons only appear once you have downloaded from different dive computers. Image B, however, groups the dives in 5m depth intervals within which the temperature for each dive is indicated (the red marks are explained below). The number of liters of back gas required for a safe ascent (2130 liters in the example above). There is continuous effort within the _Subsurface development team to add new dive computer models to those that can be downloaded from and to represent cylinder pressures correctly. One can select whether the search phrase (e.g. See the section on Renumbering the dives for instructions on this topic. Additional controllers will appear as hci1, etc. Other categorical variables include Buddy, Visibility, Rating and Suit type. A dialog box opens, showing the current Model, ID and Nickname of the dive computers used for upload. In some cases this could just be a count such as "No. Alternatively, the ffmpeg video encoder can be used to create a new video file with the dive data encoded in the video stream. The following actions are possible for managing the collection of dive sites: At the top right of the dive site management panel is a text box (see image above). The most important attribute of a CSV file is the field separator, the character used to separate fields within a single line. A very low GFLow value brings on decompression stops early during the dive. Save the set by clicking the button "Save set". when a positive setpoint is specified) but this is calculated for bail out ascents. This is a single-step process, more information about which can be found here. Lets say we wish to show dives for which the water temperature was 18 C or higher. 2.Ensure Subsurface sees the Bluetooth adapter on the host computer. Subsurface remembers the position of the dividers, so the next time Subsurface starts it uses the positions of the dividers from the last time the program was used. This brings up a dialog box (see image A below). Set the UTC time zone in the appropriate text field shown in the image below. With the dive log opened in Excel, select the round Windows button at the top left, then Save As. The Info on the top left, giving more detailed information on the dive selected in the Dive List, including some statistics for the selected dive or for all highlighted dive(s). Depending on the start time of the planned dive, the planner takes into account the gas loading during the completed dive and plans accordingly. The field separator is frequently a comma, a colon, a SPACE character or a TAB character. By reducing the values of GFHigh and GFLow to values below 100, one can build more safety into a dive. The profile can also include the dive computer reported ceiling (more precisely, the deepest deco stop that the dive computer calculated for each particular moment in time) as a red overlay on the dive profile. For more information external to this manual see: Since the colors of the heat map are not affected by the gradient factor(s), the heat map is also applicable when using the VPM-B decompression model. Record the times at which the switch from one cylinder to another was done: This is information tracked by some dive computers (provided the diver indicated these changes to the dive computer by pressing specific buttons). Specify the gas composition (e.g. This photograph of the dive computer appears in the bottom panel of the Shift times dialog. This is the default setting in Subsurface. Then add a second Location constraint, select "with substring" from the combobox and type "2 mile Reef") in the location text box (see image below). This panel controls many options for recording information in the log and for displaying the log. Renumber a few selected dives in the dive list by selecting only the dives that need renumbering. Templates are accessed using the print dialog (see image B 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 and select the Earlier radio button. If IrDA communication is required for an operating system that does not support it, an easy solution is to run Subsurface in a virtual machine (VM) that contains support for IrDA. Right-click on the dive profile to generate a dive profile context menu. Graph A indicates the start of a dive with the diver at the surface. The Dive Map on the bottom right, showing the users dive sites on a world map and centered on the site of the last dive selected in the Dive List. Clearly it is possible to construct highly refined filters. This enables a user to establish a previously-used dive computer connection by simply selecting one of the connection buttons. The measurement unit is the % of inert gas pressure above ambient pressure, relative to the Bhlmann M-value gradient (bottom of red area in A). Select "Tuesday" from the list. This means dive tables overestimate the nitrogen load incurred during previous dives. Included information of a dive is: dive number, date, time, buddy, duration, depth, temperature and atmospheric pressure: in short, most of the information that recreational divers enter into handwritten log books. c) Gas management: With open-circuit dives this is a primary consideration. The calculation takes the oxygen drop across the mouthpiece of the rebreather into account. The CSS selectors in the following table should be added. In order to refine our filter we may wish to show only dives on a Tuesday. Audience: Recreational Scuba Divers, Free Divers, Tec Divers, Professional Divers. The trip title in the Dive List panel should now reflect the edited information. Data should then be imported into www.divelogs.de. In the section dealing with dives using more than one dive computer we discussed the way in which multiple profiles for a single dive can be viewed using the left-arrow and right-arrow keyboard keys. The dive log is kept as a Microsoft SQL Compact Edition database with a. If you do not wish to apply the new preferences, select Cancel. The default it is DC1, i.e. This is done by editing the dive notes or the equipment for any one of the selected dives. Country/State/City or City/State/Country. To solve these problems, launch Subsurface with a --user= command-line option. 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). You may start typing in the box to specify a different weighting mechanism that will be saved by Subsurface. Subsurface can directly import these files when using the universal import dialog. This updates the coordinates in the Dive site management panel and moves the flag on the map to the locality corresponding to the coordinates. The time values (hour and minutes) can also be edited directly by clicking on each of them in the text box and by over-typing the information displayed. Has my SAC rate decreased over the years? See APPENDIX E for information on how to write or modify a template. For instance Dropbox offers a free application that allows files on the Dropbox servers to be seen as a local folder on a desktop computer. Within the list of dives, select the dives you would like to import later: To select certain dives: hold ctrl and click the dive, To select all dives: Select the first dive, hold down shift and select the last dive, With the dives marked, use the program menu File Export. Drag the waypoints to represent the depth and duration of the dive. Subsurface asks for a file location and file name for the saved information. Bailout: Bailout events during a CCR dive can be recorded in a Subsurface divelog. 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). Linking a dive to a dive site is performed from within the Notes tab showing the information for that dive (see the section on Locations). The script has some options mostly useful for development purposes. Generally this is close to the real air temperature. This defaults to the first gas mixture specified in the Equipment tab, which was air in the case of the profile above. The top blue row of the data table contains the column headings found in the CSV data file. The safety of a dive plan depends heavily on the way in which the planner is used. For example, 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 " # ", depicted in the image below. Select the file that needs to be imported. In the case of trimix, it is the pressures of nitrogen and helium combined. The case during CCR training is more complex if the instructor prefers a low setpoint such as 0.7 to be maintained during bailout. They are: Available Gases, Rates, Planning, Gas Options and Notes. Double-click on the appropriate dive site name with associated coordinates and that site will be associated with the dive being entered. Position the red marker by dragging it on the map, zooming in on the appropriate part of the map and placing the marker at an appropriate position (image B below). Subsurface attempts to synchronize them so that the exact times of media can be used to position media on the dive profile. Checking this option creates a lot of additional computation, to such a degree that the planner is slower than otherwise. Profile: Show only the Dive Profile of the selected dive. Subsurface keeps a local copy of the data and the cloud facility remains fully functional even if used while disconnected to the Internet. Select Import Import Log Files from the main menu. The result is shown in the panel in the image below. Below is the same dive plan as above, but with a safety stop and reduced gradient factors for a larger safety margin. That is the pressure value of inert gases at which bubble formation is expected to be severe, resulting in a significant risk of decompression sickness. Hovering the mouse over the red bookmark, the appropriate text is shown at the bottom of the information box (see D below). the type of water dived in and its salinity. Some other formats not accessible through the Import dialog are also supported, as explained below. Display the tissue heat-map. The exact amount of dive profiles that can be stored on the device depends on sample interval and duration of the dives. The planner calculates the total volume of gas used during the dive and issues a warning if you exceeds the total amount of gas available. If you import the dive profiles from these different dive computers into Subsurface, the profiles can be viewed independently. Click on the horizontal bar called Select image of dive computer showing time. Weight systems can be deleted using the dust bin icon on the left hand. This will require that you enter the same email address that you used during cloud registration. Sometimes this is unintended. How to UNDO information that has been typed. Editing dive site information from within the Notes tab is discussed in the section on Locations where each of the fields in the dive site edit panel is explained. Buddy or Rating, a binning value is not relevant and cannot be selected. Select the button "Use GPS file" to the right of the Coordinates text box (see image A above). In this range on-gassing of inert gas takes place because the inert gas pressure in the tissue compartment is lower than in the surrounding environment. Selecting the Print button in the planner allows printing of the Dive Plan Details for wet notes. Select the appropriate dives by dragging your mouse across the scattergraph (see image above) and restrict the data by activating the "Restrict to selection" button. However, in this case, do not stop using your Galileo or other IrDA-dependent dive computer. SAC, cylinder pressure, decompression ceilings, gas partial pressures and interpolated depths. This represents the increment for each bar along the horizontal axis. depth. Traditionally, gas consumption and SAC should be: consumption = tank size x (start pressure - end pressure). This is done either by using the scroll wheel / scroll gesture of the mouse or trackpad. However, the user additionally needs to load a driver for the IrDA interface with the dive computer. In order to obtain the local time for the GPS track, it is necessary to know the time zone of the dive site. You might also wish to compare different categories of dives. Subsurface can import dive logs from a range of other dive log software. Initially, the GFHigh and GFLow values in the Tech setup preferences panel of Subsurface is used. This is obvious from the top bar of the Subsurface window indicating that only some of all the dives are shown. Bluetooth is becoming a more common way of communication between dive computers and Subsurface. If this does not work, select the Clear button, then scan again for Bluetooth devices using the Scan button. However, they use advanced technology to maintain a breathable oxygen concentration: a) remove carbon dioxide from the exhaled gas. Choose the position in the video where Subsurface should try to extract the thumbnail. The functions of these buttons are described below. The Date and Time fields reflect the date and time of the dive. A line containing this new constraint is added to the filter panel with a dropdown list of days that are selectable. 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. ~/src), Run " $ ./subsurface/scripts/smtk2ssrf-build.sh ", if every thing has gone fine, you will now have an executable named smtk2ssrf in ~/src/subsurface/smtk-import/build. The Cloud Preferences dialog now has a new PIN text box, not visible previously. Show equivalent OC with pSCR pO2: The pO2 in the pSCR loop is usually lower than the pO2 of the fresh gas from the cylinder. These balloons can be moved using a drag-and-drop action. (4): Import coordinates from GPS equipment. More information about a trip can be added by selecting its trip title bar from the Dive List. Subsurface ends up ignoring surface time for many things (average depth, divetime, SAC, etc). The information entered in the Notes tab and the Equipment tab can be saved by using the two buttons on the top right hand of the Notes tab. Repetitive dives can easily be planned if the dates and start times of the repetitive dive set are specified appropriately in the top left-hand Start Time field. The list of sites can be ordered by clicking on any of the three headings. For each of these graphs, specify a threshold value. Dive Table and Cylinder: decreasing the font size allows one to see more information on a screen. But few dives are done at a constant depth corresponding to the maximum depth (i.e. This option writes the image of the dive profile(s) in a .png graphics format to the folder specified in the File save dialog. In addition to depth, it also shows the ascent and descent rates compared to the recommended speed of going up or down in the water column. A divers introduction to statistical graphs. Open logbook - Open the file manager to select a dive logbook to open. Record the cylinder changes on the dive profile: 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 Dive Profile panel and indicating the cylinder to which the change was made. c) For simple counts data, the top combobox of the Data variable needs to be set to "none". The colors are highly customizable: the Edit buttons in the Colors tab allows choosing arbitrary colors for different components of the dive log printout. The default folder is the one in which the Subsurface dive log is kept. It allows calculation of inert gas load during a dive by using the Bhlmann ZH-L16 algorithm with the addition of gradient factors as implemented by Erik Baker, or using the VPM-B model. Tags: Tags that describe the type of dive done can be entered here (separated by commas). A line containing this new constraint is added to the filter panel. This should complete the setup of video thumbnails and they should now appear on the dive profile and in the Media tab. Media can be viewed either from the dive profile or from the Media tab in the Notes Panel. not powered. Show unused cylinders: Checking this checkbox allows showing all cylinders entered for a dive in the Cylinder Table of the Equipment tab, even if one or more cylinders were actually not used. Deco ceiling: The deco ceiling calculated by Subsurface is not very accurate because the precise pressure of nitrogen in the loop can usually not be determined from the dive log imported from the CCR equipment. helium and oxygen content). Use that software to download the dive data into a known directory. Refer to Appendix C for more information. If this hand-entered dive was not in the sea but at altitude away from the sea, you may wish to edit the altitude setting in the Information tab because dives at altitude need special calculations. The decompression algorithm does not switch deco-gases automatically while in CCR mode (i.e. Subsurface can group dives into trips. Not all dive computers record this information and make it available for download; for example none of the Suunto dive computers make these data available to divelog software. Bar-charts can be rotated by 90 degrees by selecting the appropriate chart type in the Chart combobox. The atmospheric pressure can also be entered as an altitude in meters, assuming a sea-level atmospheric pressure of 1.013 bar. Information for any additional cylinders can be added by using the + button at the top right hand. This pressure has a relative value in the graph and does not indicate absolute pressure. A value of 50 bar is often used. At the top right hand is a green design panel on which the profile of the dive can be manipulated directly by dragging and clicking as explained below. The graph that has been requested (top right). Mares Dive Organizer is a Windows application. The data-numberofdives data attribute is added to the body tag to set the rendering mode. The currently used gradient factors (e.g. The position of the Information Box is saved and used again during subsequent dive analyses. This data must be used as CSS values to provide a dynamically editable template. For instance there may be information at 30-second intervals, indicating depth, water temperature, and cylinder pressure at that moment in time. Within this pop-up, there is one field called Export Path. The most important information in a simple dive logbook usually includes dive type, date, time, duration, depth, the names of your dive buddy and the divemaster or dive guide, and some remarks about the dive. Algorithm for calculating ceiling. In some cases one may want to edit the water type of a dive derived from a dive log. The pSCR metabolic rate is your rate of oxygen metabolism in liters/min (commonly between 0.5 and 2.5). To select a cylinder, the Type box should be clicked. Once it has been selected, click the Submit query button. The Dive List panel now shows only the titles for the trips. Renumber - Renumber the dives listed in the Dive List panel. The profile above indicates the dive computer-generated deco ceiling in red. c) By default the Chart combobox shows "Categorical/data points". Subsurface can directly import the database generated by the proprietary SeacSync application. Decompression is always calculated using the setpoint of the last manually entered segment. To obtain the latter, use the "Edit dive in planner" option from the Log menu. To create thumbnails for videos, do two things: Install FFmpeg on the computer that runs Subsurface. The HTML export contains a search option to search the dive log. Profile - View only the Dive Profile panel. A text box appears at the bottom right-hand of the window (see image below). DiveShare is also a dive log repository on the Internet focusing on recreational dives. For more information about Gradient factors, see the section on Gradient Factor Preference settings. Select "week day" from the list of constraints. With pSCR equipment, a very small amount of breathing gas is released every time the diver inhales. In some cases the dive profile does not fill the whole area of the. Creating a .CSV is straightforward, although the procedure is somewhat different according to which spreadsheet program is used. Bluetooth communication is often more reliable if all Bluetooth devices seen by the Subsurface computer are removed and pairing with the Bluetooth dive computer is performed from afresh. This indicates a Bluetooth controller with MAC address 01:23:45:67:89:AB, connected as hci0. For instance, typing the word "weights" into the search text box, searches throughout the user manual. Deleting a constraint: A constraint can be removed from the filter by clicking the appropriate dustbin icon on the left of the filter panel. For instance, when counts of number of dives are extracted for years, this could be in increments of a year, a quarter (3 month period) or a month. Aquapress Southend-on-Sea, UK. If there are several ports listed, use the one saying "Outgoing" instead of "Incoming". Make sure your GPS device shows the same local time as your dive computer. As in the planner, a setpoint value of zero shows the diver is breathing from an open circuit system while any non-zero value shows the use of a closed circuit rebreather (CCR). Additional waypoints can be created by double-clicking the existing dive profile. Editing this field will modify the He% according to the depth set. and thats true for an ideal gas, and its what you get taught in dive theory. Isobaric counterdiffusion information: For gas switches during the ascent in hypoxic open-circuit trimix dives information about isobaric counterdiffusion (icd) is given near the bottom of the Dive plan details, based on the rule-of-fifths (i.e. the minimum gas is typically given as: Within parentheses, the SAC factor and Problem solving time specified. Graph E indicates the situation after remaining at 4.5 meters for 10 minutes. Table: This prints a summary table of all dives selected (see below). Within the Dive List there is no way to change a saved dive plan. This is done by selecting from the Main Menu: File Find moved images. This is a critical step where most users go wrong. This appendix provides some information about approaches to export dive log data from foreign dive log software. Default cylinder: From the dropdown list, select the default cylinder to be used in the Equipment tab of the Notes panel. Bot. The dives are now exported to the file Divelog.SDE. Ubuntu 12.04 through to 15.04), there is probably not a bluetoothctl, but a script called bluez-simple-agent or just simple-agent. Check these two boxes. Bluetooth is most likely already enabled. In the case of the image above, the last six dives are checked and will be transferred to the Dive List. Important: After downloading with the above checkboxes checked, no dives are added to the Dive List but two files are created in the folder selected above: These files should be send to the Subsurface mail list: subsurface@subsurface-divelog.org with a request for the files to be analyzed. As root, type: usermod -a -G dialout johnB (Ubuntu users: sudo usermod -a -G dialout johnB) This makes johnB a member of the dialout group. METHOD 1: After downloading dives from a dive computer, the dive profiles of each is shown in the Dive profile tab, as well as a few items of information in the Notes tab (e.g. Select a smaller area of the map. The drop down list should contain all connected COM devices. Above 100% (red to white in B) the M-value gradient is exceeded and the probability of decompression sickness increases markedly. Welcome as a user of Subsurface, an advanced dive logging program with extensive infrastructure to describe, organize, interpret and print scuba and free dives. Alternatively, if you wished to compare the mean depth of your dives using different suit types, then "Suit type" would be selected as the variable for the bottom horizontal axis. To install the software, consult the Downloads page on the Subsurface web site. Gradient factors add conservatism to nitrogen and helium exposure during a dive, in a similar way that many dive computers have a conservatism setting. The procedure below is virtually identical for hand-entered dives and for dives downloaded from a dive computer. Bhlmann: Set the gradient factors (GFLow and GFHigh) for calculating the deco ceiling following the ZH-L16 algorithm. Type: id johnB This lists all the groups that johnB belongs to and verifies that the appropriate group membership has been created. In this profile the green pO2 graph diverges from the setpoint value and reflects the pO2 in the OC diluent gas (in this case air). This expands the selected trip, revealing individual dives during the trip. For pairing with the dive computer choose Control Panel Bluetooth Devices Add Wireless Device. Similarly, the highest dark green bar in A is as high as the yellow part of B. Under Template select a template to be used as the page layout. Edit this new site by selecting its edit icon and provide a name, coordinates and, if preferred, a description. The colors represent three ranges of tissue inert gas pressure: The bottom range in B (marked On-gassing) includes colors from light blue to black, representing tissue gas pressures below the equilibrium pressure of inert gas (bottom horizontal line in A). However, no oxygen setpoints are specified for pSCR dives. The setpoint data can be overlaid on the oxygen sensor data by activating both of the above check boxes. When relevant, the Information box contains information such as: ICD He:-13% N+3%>2.6%. It is essentially a three step process. This involves setting up the communications port (or mount point) of the computer with Subsurface that communicates with the dive computer. This is the variable that you are primarily interested in. If the external drive with the media is re-connected, the media can be seen in the normal way. 3.Ensure the Bluetooth-enabled dive computer is Bluetooth-discoverable and in PC upload mode. For instance, typing "Sodwana" into the Locality text box brings up all the dives for which the dive location was given as Sodwana. If, in the Chart combobox, one selects "Barchart/stacked vertical", a graph similar to image A below is generated. This lets Subsurface email security information regarding cloud storage to you, and to set up cloud storage appropriately. If only a few standard configurations are used (e.g. 2 of 2"). Note that this dive lasted over two hours. Click on the Edit heading in the main menu and an option appears to undo the change in time (image c). When finished, select the OK button on the bottom right of the dialog. The OSTC dives are shown in the Dive List panel. 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). All the selected dives now contain the data initially selected in the original source dive log. This tab shows the number of dives selected, the total amount of dive time in these dives, as well as the minimum, maximum and mean for the dive duration, water temperature and surface air consumption (SAC). The air consumption graph displays the tank pressure and its change during the dive. However, on-gassing of slower tissues continues during the deep stops, which leads to greater oversaturation gradient in slower tissues at the end of the dive. This can be determined by opening the file with a text editor. If a trip includes, for example, ten dives, you can split this trip into two trips (trip 1: top four dives; trip 2: bottom six dives) by selecting and right-clicking the top four dives. Edit the Nickname field for the appropriate dive computer.
