Section 7: Display - Setting Up SEASAVE Displays Copy Options Tab The copy options tab defines the plot type and size for copying to the clipboard (as a Windows metafile, JPG, or bitmap). The Copy Options tab looks like this: SEASAVE automatically uses selected format (metafile, JPG, or bitmap) when copying plot to clipboard. SEASAVE prompts you to select format (metafile, JPG, or bitmap) when copying plot to clipboard.
Section 7: Display - Setting Up SEASAVE Displays Viewing SEASAVE Plots Shown below is an example plot: Toolbar – Click appropriate button to scroll, zoom, undo, print, copy to clipboard, or save. Right click in plot to make changes/selections: • Modify – change plot setup; Plot Display dialog box appears. • Export Display Settings (.dsa file) – export setup to .dsa file; Save As dialog box appears. • Print, Copy, Save as – See description below.
Section 7: Display - Setting Up SEASAVE Displays Status Display The Status display provides the following information: • If SEASAVE is acquiring real-time data or playing archived data. • If SEASAVE is storing real-time data to a file; output data file name. • Instrument configuration (.con) file name. In the Display menu, select Status.
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Note: To start acquisition without a mouse: With the cursor in the main SEASAVE window, press the Alt key to show the keyboard shortcuts (underlines) on menus. Press the appropriate letter (for example, R for Real-Time Data menu) and use the arrow and Enter keys to navigate.
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Starting and Stopping Real-Time Data Acquisition 1. In the Real-Time Data menu, select Start. The Start Real-Time Data Acquisition dialog box appears: • Store data on disk to store raw (frequencies, A/D counts, and/or voltages) real-time data. • Delay storing data to disk until Start Archiving command is sent to control when data begins to be written to file.
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition 2. Note: Outputs and displays can be reconfigured without interrupting data acquisition. For example: • If you start a cast and realize that you forgot to set up serial data output, you can select Configure Outputs and make and save the desired changes, without interrupting data acquisition. Once the changes are saved, serial data will output to the desired COM port.
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Firing Bottles Note: The .bl file has the same path and file name as the data file. For example, if the data file is c:\test1.hex, the .bl file is c:\test1.bl. Water sampler bottles can be fired by command from SEASAVE. SEASAVE automatically writes bottle sequence number, bottle position, date, time, and beginning and ending scan numbers to a bottle log (.
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Marking Scans Note: The .mrk file has the same path and file name as the data file. For example, if the data file is c:\test1.hex, the .mrk file is c:\test1.mrk. Mark Scan allows you to copy the most recent scan of data to a mark (.mrk) file as desired. The .
Section 8: Real-Time Data and Real-Time Control - Real-Time Data Acquisition Turning Pump On / Off SEASAVE allows you to manually turn a SBE 9plus’ pump on and off during data acquisition, for a custom version of the 9plus. This may be useful if your system is integrated with an acoustic instrument, to provide a quiet period during its data acquisition.
Section 9: Archived Data - Displaying Archived Data Section 9: Archived Data - Displaying Archived Data Note: To display data without a mouse: With the cursor in the main SEASAVE window, press the Alt key to show the keyboard shortcuts (underlines) on menus. Press the appropriate letter (for example, A for Archived Data menu) and use the arrow and Enter keys to navigate. SEASAVE can be used to display and plot archived data: 1. In the Archived Data menu, select Start.
Section 9: Archived Data - Displaying Archived Data Note: Archived data playback can be very fast if No Wait is selected, if there is no scrolled view display. For an example data file with 392,000 scans, archived data playback took 19 seconds if only a plot display was generated; adding a scrolled display caused playback to take 13 minutes! 2. Click Start to begin processing and displaying data. 3. To pause and restart data display: A. In the Archived Data menu, select Pause.
Section 10: Processing Data Section 10: Processing Data Sea-Bird provides software, SBE Data Processing, for converting the raw .hex data file into engineering units, editing (aligning, filtering, removing bad data, etc.) the data, calculating derived variables, and plotting the processed data. However, sometimes users want to edit the raw .
Section 10: Processing Data 5. In the File menu, select Save (not Save As). If you are running Windows 2000, the following message displays: You are about to save the document in a Text-Only format, which will remove all formatting. Are you sure you want to do this? Ignore the message and click Yes. 6. In the File menu, select Exit.
Appendix I: Command Line Operation Appendix I: Command Line Operation SEASAVE has several command line parameters, for infrequently used options: Parameter Function -autostart= Automatically start SEASAVE and data acquisition, using filename program setup (.psa) file defined by filename. Filename must include path and extension (.psa). SEASAVE uses .con file, setup in Configure Inputs and Configure Outputs, displays, and output file name defined in .psa file.
Appendix II: Configure (.con) File Format Appendix II: Configure (.con) File Format Note: Modify the .con file by selecting Configure Inputs, clicking on the Instrument Configuration tab in the dialog box, and clicking on Modify. Shown below is a line-by-line description of the .con file contents, which can be viewed in a text editor.

Appendix III: Software Problems Appendix III: Software Problems Considerable effort has been made to test and check this software before its release. However, because of the wide range of instruments that Sea-Bird produces (and interfaces with) and the many applications that these instruments are used in, there may be software problems that have not been discovered and corrected. If a problem occurs, please contact us via phone (425-643-9866), e-mail (seabird@seabird.
Appendix IV: Derived Parameter Formulas Appendix IV: Derived Parameter Formulas Note: Algorithms used for calculation of derived parameters in SEASAVE and in SBE Data Processing’s Data Conversion, Derive, and SeacalcW modules are identical, except as noted. For formulas for the calculation of conductivity, temperature, and pressure, see the calibration sheets for your instrument.
Appendix IV: Derived Parameter Formulas density = ρ = ρ (s, t, p) [kg/m3] (density of seawater with salinity s, temperature t, and pressure p, based on the equation of state for seawater (EOS80)) (Note: To calculate gravity for the density algorithm, SEASAVE uses the latitude from a NMEA navigation device, if NMEA is enabled in the .con file. If your system does not have NMEA, enter the desired latitude on the Miscellaneous tab in Configure Inputs.
Appendix IV: Derived Parameter Formulas depth = [m] (Note: To calculate gravity for the depth algorithm, SEASAVE uses the latitude from a NMEA navigation device, if NMEA is enabled in the .con file. If your system does not have NMEA, enter the desired latitude on the Miscellaneous tab in Configure Inputs.
Appendix IV: Derived Parameter Formulas sound velocity = [m/sec] (sound velocity can be calculated as Chen-Millero, DelGrosso, or Wilson) Sound velocity calculation: C Computer Code – // Sound Velocity Chen and Millero double SndVelC(double s, double t, double p0) /* sound velocity Chen and Millero 1977 */ /* JASA,62,1129-1135 */ // s = salinity, t = temperature deg C ITPS-68, p = pressure in decibars { double a, a0, a1, a2, a3; double b, b0, b1; double c, c0, c1, c2, c3; double p, sr, d, sv; p = p0 / 10.
Appendix IV: Derived Parameter Formulas p=p Σ average sound velocity = Δp,p=min di [m/s] p=p Σ Δp,p=min di / vi Average sound velocity is the harmonic mean (average) from the surface to the current CTD depth. The average is calculated on the downcast only. The first window begins when pressure is greater than a minimum specified pressure and salinity is greater than a minimum specified salinity.
Appendix IV: Derived Parameter Formulas potential temperature [IPTS-68] = θ (s, t, p, pr) [° C] (Potential temperature is the temperature an element of seawater would have if raised adiabatically with no change in salinity to reference pressure pr. Sea-Bird software uses a reference pressure of 0 decibars).
Appendix IV: Derived Parameter Formulas Descent rate and acceleration are computed by calculating the derivative of the pressure signal with respect to time (with a user-input window size for calculating the derivative), using a linear regression to determine the slope. Values computed by SEASAVE and SBE Data Processing’s Data Conversion module are somewhat different from values computed by SBE Data Processing’s Derive module.
