Printing in color, done by checking the box with Print in color. This is especially useful when using Bluetooth-equipped dive computers that need to establish a Bluetooth connection each time a download is done. Note that the number in the file name depends on how many USB devices you have connected, and must be adjusted appropriately. Gradient factors add conservatism to nitrogen and helium exposure during a dive, in a similar way that many dive computers have a conservatism setting. If a description for a dive site has previously been entered, this is shown in the panel as well as the number of dives at each site. Atomic Logbook is Windows software by Atomic Aquatics. This loads the existing configuration from the dive computer to Subsurface, showing it in the configuration panel. In this graph it appears that SAC rate has decreased from around 21 l/min to around 14 l/min between 2013 and 2021. Pre-installed templates or a custom written template can be used to choose where the data are fitted into the page. If the display of media is activated (using the toolbox icon to the left of the Dive Profile), the program shows only the thumbnails and the images cannot be viewed at full-screen size. The appropriate settings need to be set in the Media Preferences (FilePreferencesMedia). When using a Shearwater Predator/Petrel/Nerd, select Dive Log Upload Log and wait for the Wait PC message. Entering a new dive location: On the other hand, having dived at a new dive site, a new record needs to be created that could be used for the new and for later dives at this new site. Many divers log their dives using the proprietary software provided by the manufacturers of their dive computers. Does the cable work using other software? Click the appropriate radio button (see images below). Additional controllers will appear as hci1, etc. 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 approach the gradient factor value (i.e. A 1:10 ratio is commonly used. This expands the selected trip, revealing individual dives during the trip. The heat map summarizes, for the duration of the dive, the inert gas tissue pressures for each of the 16 tissue compartments of the Bhlmann model. Many of the new desktop operation systems (e.g. Although its a popular configuration for cave divers, sidemount diving can be done by recreational divers who have completed the appropriate training. The Water type/density field shows the information reported by the dive computer. Then select Edit. The graph below shows the SAC rates as a function of dive depth for the restricted dataset created above. Secondly, recreational dive tables are not designed to build additional safety features into a dive. In this situation, the data reflect the time point along the dive profile shown by the mouse cursor (see right-hand part of figure (B) above where the Information Box reflects the situation at the position of the cursor [arrow] in that image). Subsurface keeps a local copy of the data and the cloud facility remains fully functional even if used while disconnected to the Internet. This brings up a list button that can be used to display a dropdown list of cylinders: The drop-down list can then be used to select the cylinder type that was used for this dive, or just start typing in the box which shows the available options for the entered characters. The most important attribute of a CSV file is the field separator, the character used to separate fields within a single line. 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. The Dive Profile on the top right, showing a graphical dive profile of the selected dive in the Dive List. Data should then be imported into www.divelogs.de. Detailed instructions for registering on the cloud server are provided in the Cloud preference panel (see above image), as well as in the section of this manual dealing with: Keeping a Subsurface dive log in the cloud. If you encounter any problems during the cloud registration process, read the, Open circuit diving is often part of a pSCR dive because, at shallow depths, the pO, It is often necessary to plan for a worst-case bailout event in order to ensure sufficient bailout gas to reach the surface, taking into account decompression. For instance, Gnome3 shows a Bluetooth icon on the right of the toolbar at the top of the screen. By default Subsurface selects the most appropriate graph type, but this is a user-selectable option. The HTML export cannot be changed or edited. An increasing number of dive computers use Bluetooth Low Energy (BTLE) as a means of communication. After the media have been loaded, they appear in two places: the Media tab of the Notes Panel (left part of image below). Question: I cannot download all my dives, only the most recent ones, even though my dive computers manual states that it records history of e.g. This information is usually obtained from your ISP or your network technician. Within Dive Organizer, select Database Backup from the main menu and back up the database to the desk top. 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). Type the name of the new dive site into the text box (image A below). Use that software to download the dive data into a known directory. If it is launched without parameters in a graphical user interface, a simple window opens for choosing the .slg file(s) to import and a destination file to store the Subsurface-formatted data into (see image below). This is about the minimum amount of information required for a coherent dive log. For more information on configuring a CSV import, see Importing data in CSV format. This information is only shown for gas changes relevant with respect to icd. This brings up a dialog box (see image A below). After specifying the weight system, save the data by pressing ENTER on the keyboard or by clicking outside the cell with the cursor. In the resulting file selection menu, select CSV files (towards the bottom right). Divelogs.de supports a few additional logbook formats that Subsurface currently cannot handle. Because all statistical results in Subsurface are shown as graphs, formulating an appropriate specification requires four steps: This dive has photographs or videos taken during the dive, typically using an underwater camera. Remember for some dive computers progress information could be inaccurate since Subsurface doesnt know how much downloadable data there are until the download is complete. Animations: Some actions in showing the dive profile are performed using animations. Markers are placed against the depth profile line, with the time of the event determined by the mouse cursor when the right mouse button was clicked to bring up the menu. Ubuntu 12.04 through to 15.04), there is probably not a bluetoothctl, but a script called bluez-simple-agent or just simple-agent. A way to solve this problem is to create a virtual machine on your desktop with a guest operating system that still does support IrDA. Cylinder pressure data are not logged by the APD equipment but can be manually entered in the Equipment Tab. The blue bar disappears (image B above) and the globe icon on the right-hand of the location name text box turns blue. In order to upload to Divelogs.de, you need a user-ID as well as a password for Divelogs.de. The dive site information of all dives is managed as a separate entity independent of the dive information. The Subsurface window is usually divided into four panels with a Main Menu (File Edit Import Log View Help) at the top of the window (for Windows and Linux) or the top of the screen (for Mac and Ubuntu Unity). The blue row of balloons immediately above these contains the names understood by Subsurface. Open cloud storage - Open the dive log previously saved in Cloud storage. Some divers like to record the sea conditions during a dive. Install a scaled down version of the guest operating system to minimize its demands on the host system. This step should only be needed once for initial setup. One way to achieve this is to use bluetoothctl: After the devices are paired, press the Save button of the dialog. Generally this is close to the real air temperature. For instance, the axis values for depth and time change from dive to 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. Specifying the gas composition: The gas composition used is indicated along the line segments of the dive profile. If there are multiple controllers running, its easiest to turn off the unused controller(s). The checkbox marked Download into new trip ensures that, after upload, the downloaded dives are grouped together as a new trip(s) in the Dive List. Add a size and start pressure for that cylinder (image below). For more information see: Subsurface provides a geo-lookup service (that is, given the coordinates of a dive site) derived from a click on the Dive Map panel at the bottom right of the Subsurface window, or from a GPS instrument or from the Subsurface-Mobile app). In the Divelist, all dives with associated media have an icon indicating whether the media were taken during the dive, just before/after the dive or both during and before/after the dive. In addition, the Tech setup Preferences panel allows one to activate a checkbox labelled Show equivalent OC pO2 with pSCR pO2. Right-click on the dive profile to generate a dive profile context menu. Each line contains the information for a single instant in time during the dive, 30 seconds after that of the previous instant. Graph E indicates the situation after remaining at 4.5 meters for 10 minutes. Profile: Show only the Dive Profile of the selected dive. For more information about Gradient factors, see the section on Gradient Factor Preference settings. This can be determined by opening the file with a text editor. If the water type of a dive differs from that of the dive computer setting during the dive, a warning is shown to alert you. This procedure is called the "minimum gas" or "rock bottom" consideration and it is used by various (but not all) technical diving organizations. The Cloud Preferences dialog now has a new PIN text box, not visible previously. To see thumbnails that represent individual videos, Subsurface uses an external program called FFmpeg. For pSCR dive profiles the dive ceiling is adjusted for this oxygen drop, and often requires longer decompression periods. As a last step in refining our filter we may wish to add another constraint specifying visibility of at least three stars. Depth, Mean Depth, Buddy, Notes, Weight and Tags). The figure below explains in greater detail how the heat map can be interpreted. Right-click on the red flag. Subsurface also calculates ceilings independently, shown as a green overlay on the dive profile. Graph D shows the pressures after ascent to a depth of 4.5 meters. Local default file: When checked, Subsurface automatically loads a dive log from the local hard disk. c) By default the Chart combobox shows "Categorical/data points". See the text below for a detailed explanation. Normally the Information Box is located to the top left of the Dive Profile panel. If you click the + button on the top right of the weights dialog, the table looks like this: By clicking on the Type field, a drop-down list becomes accessible through a down-arrow: This can be used to select the type of weight system used during the dive. Below is a dive profile for a CCR dive with bailout at 57 minutes. Commonly used values are 1.4 bar for the bottom part of the dive and 1.6 bar for any decompression stages. Check any warning and error messages in the console or in the graphical window: some may be relevant as support for Galileo family of dive computers is still a work in progress. The Apply changes button should be selected after all the profile segments for a dive has been entered. But in cases where that doesnt work, some googling to find the correct driver for a specific download cable may be necessary. The context menu is used in many functions described below. The ability to rapidly create subsets of data for display (using the restriction tool) creates a powerful mechanism to do rapid but detailed analysis of a dive log. Both methods are described here. This is a single-step process, more information about which can be found here. Recreational mode is intended for what most divers would call "recreational", "sports"or "nontechnical" dives, remaining within no-deco limits (NDL). The Equipment tab allows entering information about the type of cylinder and gas used, as well as the weights used for the dive. With this information, importing the data into Subsurface is straightforward. To plan a dive, the appropriate settings need to be defined. If one wishes, one can expand the dive information by using the Equipment tab to record information about the equipment used: cylinders and their start and end pressures, dive suit used and weight system used. Since dive suit and Rating are categories, a scattergraph is not appropriate. Here is an example of information for a dive with two types of weights: integrated as well as a weight belt: Allow divers to enter information about the environment with respect to a specific dive. Show mean depth: If this box is checked, the Dive Profile panel contains a grey line that shows the mean depth of the dive, up to any time instant during the dive. Except for Shearwater CCR dive computers, CCR dive data are currently obtained from the proprietary software provided when purchasing CCR dive equipment. This export option is primarily intended to be accessible to external software for further processing of the Profile Panel information. On the Dive Computer drop-down list, the model name of the dive computer must be selected, e.g. The Filter text box to list similar languages. Define the amount of gas the cylinder must have at the end of the bottom section of the dive just before ascent. In addition, start and end pressures for both oxygen and diluent cylinders are shown in the Equipment Tab. If this site is then deleted, the location(s) of dives that used this site would need to be created. Note that the thumbnail on the dive profile has a small dustbin icon in the bottom right hand corner (see image above). This closes the Bluetooth dialog. CSV files can be used in many contexts for importing data into a Subsurface dive log. Subsurface offers an unique graphical interface for doing planning. Available gases: In the Available gases table, enter the cylinder information for the diluent cylinder and for any bail-out cylinders. Specific instructions for downloading dives using Bluetooth are given in the section above, Download of dive logs from the MkVI is performed using a custom communications adapter and the, The dive logs of an APD Inspiration or similar CCR dive computer are downloaded using a communications adapter and. By default this is a nonspecific placeholder thumbnail. Knowing a few basic things about the content of the CSV file helps with a smooth import of the dives into Subsurface. Editing this field will modify the He% according to the depth set. The descent rate is also specified. The VLC video player automatically finds this file upon playing the video and overlays the dive data. A warning icon is shown if the water type reported by the dive computer currently displayed is different from the value that is typed here. To plan a dive using a closed circuit rebreather, select the CCR option in the dropdown list, circled in blue in the image below. This allows you to create a custom dive plan, suited to yourself as well as the dive conditions. See APPENDIX D: Exporting a spreadsheet to CSV format for information that may be helpful for importing spreadsheet-based data into Subsurface. This brings up the possibility to Undo or Redo an action. This information is given near the bottom of the Dive plan details, following the calculation of bottom gas used during the dive if it exactly follows the plan. the inert gas pressure in the tissue compartment equals that of the water in which the diver is. The operating system of the desktop computer needs the appropriate drivers in order to communicate with the dive computer, the way the dive computer prefers (e.g. Renumber a few selected dives in the dive list by selecting only the dives that need renumbering. For instance, by typing cav, the tags cave and cavern are shown to choose from. This map is not editable. However, BTLE is not a standardized protocol, consequently adaptations need to be made for communicating with each different dive computer model. The reporting of events is therefore a function of the dive computer used. For instance, filtering lets you list the dives during a particular year at a specific dive site, or otherwise the cave dives with a particular buddy. An appropriate icon is shown on the depth profile (see image below). Image D is a compilation of similar color mappings of 16 tissue compartments during a 10-minute period of a dive, the colors representing the inert gas loading of a tissue compartment at a point in time during the dive. Open the Regional and Language Options dialog box. Because, after moving media, large numbers of files may need to be deleted and re-imported from the new disk, Subsurface can locate the media based on their filename and path. 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. Under current Linux, the kernel already provides for communication using the IrDA protocol. The data-numberofdives data attribute is added to the body tag to set the rendering mode. On a Mac users sometimes have to manually hunt for the correct driver. The position of the Information Box is saved and used again during subsequent dive analyses. Divers used to spreadsheets may prefer a pie chart for these data, achieved by selecting "Categorical/piechart" from the Chart combobox. The above process can be made user-friendly by creating a link/shortcut with a desktop icon that executes the above command-line instruction. It is possible to simultaneously provide counts for two variables. In the above example of a bar graph, select the bars for the two years of interest by clicking on them and activate the "Restrict to selection" button towards the bottom left of the Statistics panel. This tab sets common variables used for decompression calculations pertaining to technical diving. This is easily done in Subsurface. Bailout: Bailout events during a CCR dive can be recorded in a Subsurface divelog. Hidden events can be restored to view by selecting Unhide all events from the context menu. Is my SAC rate related to diving with different dive suits? This represents the increment for each bar along the horizontal axis. Clicking the "Done" button in the edit panel returns you to the dive sites management panel.
