Section 1: Introduction System Requirements Sea-Bird recommends the following minimum system requirements for SEASOFT-Win32: Pentium 90 CPU, 64 Mbyte RAM, Windows 98 or later.
Section 2: Installation and Use Section 2: Installation and Use SEASAVE requires approximately 9 Mbytes of disk space during installation. Ensure there is room on your hard drive before proceeding. Sea-Bird recommends the following minimum system requirements for SEASOFT-Win32: Pentium 90 CPU, 64 Mbyte RAM, Windows 98 or later. Installation 1. Note: Sea-Bird supplies the current version of our software when you purchase an instrument.
Section 2: Installation and Use SEASAVE Use SEASAVE Window Note: SEASAVE can be run from the command line. See Appendix I: Command Line Operation. To start SEASAVE: • Double click on seasave.
Section 2: Installation and Use • Notes: • The algorithms used to calculate derived parameters in SEASAVE are the same as used in SBE Data Processing’s Derive and Data Conversion modules (with the exception of the oxygen calculation). See the SBE Data Processing manual on our website or the SBE Data Processing Help files for details.
Section 2: Installation and Use Getting Started Displaying Archived Data - Sea-Bird Demo Files SEASAVE can be used to display archived raw data in a .hex or .dat file. Sea-Bird provides example files with the software to assist you in learning how to use SEASAVE. These files are automatically installed on your hard drive when you install SEASAVE; the default location is: C:\Program Files\Sea-Bird\SS-WIN32-DEMO The demo files include: • one data file - demo.dat • one instrument configuration file - demo.
Section 2: Installation and Use Acquiring and Displaying Real-Time Data Follow these steps to get started using SEASAVE to acquire and display real-time data: 1. Set up the instrument, and define SEASAVE operating parameters (see Sections 3, 4, and 5: Configure Menu): • Instrument Configuration (.con) File - define what sensors are integrated with the instrument, each sensor’s calibration coefficients, and what other data is integrated with the data stream from the instrument.
Section 2: Installation and Use File Formats File extensions are used by SEASOFT to indicate the file type. Input files for real-time data acquisition: Extension .con .cfg .dsf .dso .dss Description Instrument configuration - number and type of sensors, channel assigned to each sensor, and calibration coefficients. SEASAVE uses this information to interpret the raw data from the instrument. Latest version of .
Section 2: Installation and Use Output files from real-time data acquisition: Extension .bl .dat .hex .hdr .mrk .nav .txt Description Bottle log information - output bottle file, containing bottle firing sequence number and position, date, time, and beginning and ending scan numbers for each bottle closure.

If the SBE 14 is connected directly to an SBE 11plus Deck Unit, Remote Display alarm setup is done by sending commands to the SBE 11plus using SEATERM. The SBE 14 Remote Display can be set up to turn an alarm on when pressure is less than and/or more than a specified amount.
Section 3: Configure Menu, Part I - General System Setup ASCII Output SEASAVE can output ASCII data (converted data in engineering units) to a COM port on your computer or to a shared file on your computer. If outputting ASCII data to a shared file, you can use Word, Notepad, or some other program to open and look at the data while SEASAVE continues to acquire more data.
Section 3: Configure Menu, Part I - General System Setup Header Form Note: A header is automatically included in the data (.dat or .hex) file and in the header (.hdr) file. The header includes software version, sensor serial numbers, instrument configuration, date and time of start of data acquisition, etc. There can be up to two date/time listings in the header. The first, System Upload Time, is always the date and time from the computer.
Section 3: Configure Menu, Part I - General System Setup When you begin data acquisition, (if you chose to store the data on disk) the header form appears for you to fill in. The user-selected prompts (Ship, Cruise, Station, Latitude, and Longitude) appear to the left of the blank fields.

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)) Density calculation: Using the following constants B0 = 8.24493e-1, B1 = -4.0899e-3, B2 = 7.6438e-5, B3 = -8.2467e-7, B4 = 5.3875e-9, C0 = -5.72466e-3, C1 = 1.0227e-4, C2 = -1.6546e-6, D0 = 4.8314e-4, A0 = 999.842594, A1 = 6.793952e-2, A2 = -9.095290e-3, A3 = 1.001685e-4, A4 = -1.120083e-6, A5 = 6.
Appendix IV: Derived Parameter Formulas depth = [m] Depth calculation: C Computer Code – // Depth double Depth(int dtype, double p, double latitude) // dtype = fresh water or salt water, p = pressure in decibars, latitude in degrees { double x, d, gr; if (dtype == FRESH_WATER) /* fresh water */ d = p * 1.019716; else { /* salt water */ x = sin(latitude / 57.29578); x = x * x; gr = 9.780318 * (1.0 + (5.2788e-3 + 2.36e-5 * x) * x) + 1.092e-6 * p; d = (((-1.82e-15 * p + 2.279e-10) * p - 2.2512e-5) * p + 9.
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 = ∆p,p=min di [m/s] p=p Σ ∆p,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. Depth is calculated from pressure based on user-input latitude.
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 computed by SEASAVE and SBE Data Processing’s Data Conversion module are somewhat different from values computed by SBE Data Processing’s Derive module, because the algorithms calculate the derivative of the pressure signal with respect to time, using a linear regression to determine the slope.
