Overview

SEASOFT© consists of modular, menu-driven routines for acquisition, display, processing, and archiving of oceanographic data acquired with Sea-Bird equipment. SEASOFT-Win32 is designed to work with a PC running Win 95/98/NT/2000/XP.

SEASOFT-Win32 is actually several stand-alone programs:

•	SEATERM and SeatermAF terminal programs that send commands to instrument for status, data acquisition setup, data retrieval, and diagnostics

•	SEASAVE program that acquires and displays real-time data, and also displays archived data - THIS PROGRAM

•	SBE Data Processing program that converts, edits, processes, and plots data

•	Plot39 - plotting program for SBE 39 and SBE 48 data.

NOTE

The following SEASOFT-DOS calibration modules are not yet available in SEASOFT-Win32:

•	OXFIT – compute oxygen calibration coefficients

•	OXFITW – compute oxygen calibration coefficients using Winkler titration vales

•	OXSAT – compute oxygen saturation as a function of temperature and salinity

•	PHFIT – compute pH coefficients

The Windows version of SEASAVE includes the functions incorporated in SEASOFT-DOS’ SEACON and SEASAVE programs. SEASAVE:

•	acquires real-time, raw data (frequencies and voltages) and saves the raw data to the computer for later processing

•	displays selected raw and/or converted (engineering units) real-time or archived data in text and plot displays

Additional SEASAVE features include the ability to:

•	send commands to close water sampler bottles

•	save NMEA navigation data with the CTD data

•	save user-input header information with the CTD data, providing information that is useful for identifying the data set

•	output converted (engineering units) data to a computer COM port or file on the computer

•	output data to a remote display

•	set up alarm parameters

•	mark real-time data to note significant events in a cast

Sea-Bird recommends the following minimum system requirements for SEASOFT-Win32: Pentium 90 CPU, 64 Mbyte RAM, Windows 98 or later.

SEASAVE supports the following Sea-Bird instruments:

•	SBE 911plus, 917plus, 911, and 911e CTD system

•	SBE 16plus  and 16 SEACAT C-T Recorder

•	SBE 19plus  and 19 SEACAT Profiler

•	SBE 21 SEACAT Thermosalinograph

•	SBE 25 SEALOGGER CTD

•	SBE 31 Multi-Channel Counter

•	SBE 45 MicroTSG Thermosalinograph

•	SBE 49 FastCAT CTD Sensor

Additionally, SEASAVE supports many other sensors/instruments interfacing with the instruments listed above, including Sea-Bird oxygen, pH, and ORP sensors, SBE 32 Carousel Water Sampler, and assorted equipment from third party manufacturers.


Differences from DOS Version

SEASOFT was previously available in a DOS version (SEASOFT-DOS). Following are the differences between SEASOFT-DOS and SEASOFT-Win32, as they relate to SEASAVE:

1	SEASOFT-Win32 includes several stand-alone programs; you can install any or all of these programs as desired:

•	SEASAVE - Windows-based SEASAVE replaces SEASAVE and SEACON in SEASOFT-DOS.

•	SBE Data Processing - replaces the data processing programs and SEACON in SEASOFT-DOS.

•	Terminal Programs - Windows-based terminal programs SEATERM and SeatermAF replace the terminal programs in SEASOFT-DOS (TERM1621, TERM17, TERM19, TERM25, TERM37, TERMAFM, TERM11, and TMODEM).

•	Plot39 - Windows-based plotting program for SBE 39 and SBE 48 data.

2	SEASAVE now supports use of serial ports COM1 through COM10.

3	Up to 10 displays can be active on the desktop at once. Displays can be added, deleted, and modified without interrupting data acquisition.

4	Each display in the SEASAVE window has its own display setup file. Save the file to a new name after modifying the display to build an accessible list of pre-configured displays. File extensions for display setup files vary, depending on the display type: .dso extension for overlay (X-Y) displays, .dsf extension for fixed displays, and .dss extension for scrolled displays.

5	Processing capability (for example, for interfacing to additional auxiliary sensors) added to our software after November 2000 has been added only to the Windows version.


SEASAVE Window

SEASAVE’s main window looks like this:

•	Menus -- The Menus contain options for setting up the instrument and the displays, as well as for starting data acquisition.

•	Toolbar -- The Toolbar contains buttons for adding and setting up the displays. To display or hide the Toolbar, select Toolbar in the View menu.

•	Status Bar -- The Status bar is located at the bottom of the screen, and provides the following information:

•	If SEASAVE is storing data to disk (acquiring data) or reading archived data

•	Output data file name

•	Instrument configuration (.con) file name

To display or hide the Status bar, select Status bar in the View menu.

•	Display windows -- SEASAVE can display up to 10 windows. The windows can be set up to display real-time data (conductivity, temperature, pressure, etc.) as well as calculated parameters such as salinity and sound velocity. The three window types -- fixed, scrolled, and overlay (plot) -- are briefly described below; their setup is described in detail in Add / Edit Display Window.

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.

•	Oxygen computed by SEASAVE and SBE Data Processing’s Data Conversion module is somewhat different from values computed by SBE Data Processing’s Derive module, because the algorithm uses the derivative of the oxygen signal with respect to time. SEASAVE and Data Conversion compute the derivative looking backward in time, since they share common code and SEASAVE cannot use future values of oxygen while acquiring data in real time. Derive uses a centered window (equal number of points before and after the scan) to obtain a better estimate of the derivative. Use SEASAVE (or Data Conversion) to obtain a quick look at oxygen values; use Derive to obtain the most accurate values.

•	If your data includes underwater and surface PAR data, you can select Corrected Irradiance [CPAR] as an output variable. SEASAVE calculates:
CPAR = 100 * ratio multiplier * underwater PAR / surface PAR
where
ratio multiplier = scaling factor used for comparing light fields of disparate intensity; input in .con file entry for surface PAR sensor.
underwater PAR = underwater PAR data.
surface PAR = surface PAR data.
For complete description of ratio multiplier, see Application Note 11S (11plus Deck Unit) or 47 (SBE 33 or 36 Deck Unit).

Fixed Display Window

The Fixed Display window has a vertical list of the selected parameters to the left, and displays their current values to the right.

Scrolled Display Window

The Scrolled Display window has a list of the selected parameters across the top, and displays the data in scrolling vertical columns.

Overlay (plot) Window

The Overlay Display window plots 1 parameter on the y-axis and up to 4 parameters on the x-axis.


Input and Output Files

File extensions are used by SEASOFT to indicate the file type:

Input Files for Real-Time Data Acquisition

FILE EXTENSION	DESCRIPTION
.con	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 .con file for your instrument is supplied by Sea-Bird when the instrument is purchased, upgraded, or calibrated. If you make changes to the instrument (add or remove sensors, recalibrate, etc.), you must update the .con file. The .con file can be viewed and/or modified in SEASAVE’s Configure menu.
.cfg	SEASAVE configuration -- size, placement of, and update rate for each display window, setup file (.dsf, .dso, and .dss files) name for each display window, and all configuration information (instrument .con file name as well as setup for alarms, ASCII output, header, mark scans, NMEA interface, remote display, and water sampler). The .cfg file can be selected and saved in SEASAVE’s File menu. Note that SEASAVE always opens to the configuration specified in seasavew.cfg  (default location C:\Program Files\Sea-Bird\Seasave-Win32).
.dsf	Fixed display window setup -- desired parameters and number of digits for data display. The .dsf file setup can be viewed and/or modified in SEASAVE’s ScreenDisplay menu.
.dso	Overlay (plot) display window setup - desired parameters and number of digits for data display, and plot characteristics (labels, grids, etc.). The .dso file setup can be viewed and/or modified in SEASAVE’s ScreenDisplay menu.
.dss	Scrolled display window setup -- desired parameters and number of digits for data display. The .dss file setup can be viewed and/or modified in SEASAVE’s ScreenDisplay menu.
Output Files from Real-Time Data Acquisition

FILE EXTENSION	DESCRIPTION
.bl	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. Beginning and ending scan numbers correspond to approximately 1.5-second duration for each bottle. Information is written to file by SEASAVE each time a bottle fire confirmation is received from a water sampler. File can be used by SBE Data Processing’s Data Conversion module.
.dat	Data file -- binary raw data file created by SEASAVE from real-time data stream from SBE 911, 911e, or 911plus. File includes header information. File can be used by SBE Data Processing’s Data Conversion module.
.hex	Data file: • Hexadecimal raw data file created by SEASAVE from real-time data stream from SBE 16, 16plus, 19, 19plus, 21, 25, and 49. Data uploaded from instrument’s memory (not applicable to SBE 49) also has this extension. • Data uploaded from SBE 17plus (used with SBE 9plus CTD). • Converted (engineering units) data file created by SEASAVE from real-time data stream from SBE 45. File includes header information. File can be used by SBE Data Processing’s Data Conversion module.
.hdr	Header file – Includes same header information (software version, sensor serial numbers, instrument configuration, etc.) as in .hex or .dat data file.
.mrk	Mark scan information -- output marker file containing sequential mark number, system time, and data for selected variables. Information is written to file by SEASAVE when user clicks on Mark Scan during real-time data acquisition to mark significant events in the cast. File can be used by SBE Data Processing’s Mark Scan module.
.nav	Navigation information -- output navigation file (for system integrated with NMEA Lat/Lon device) containing latitude, longitude, time, scan number, and pressure. Information is written to file by SEASAVE when user clicks on Add to .nav File during real-time data acquisition to mark significant events in the cast.
.txt	ASCII output -- output file created if you configure SEASAVE to output ASCII data to a shared file.


Getting Started

To Display 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:

•	1 data file -- demo.dat

•	1 instrument configuration file -- demo.con (defines instrument sensors, calibration coefficients, etc.)

•	1 or more display setup files for each type of display -- fixed (.dsf extension), scrolled (.dss extension), and overlay (.dso extension)

•	3 SEASAVE configuration files -- these have a .cfg extension. The .cfg file defines the size, placement, update rate, and setup file name for each display window; and all configuration information (instrument .con file name as well as setup for alarms, ASCII output, header, mark scans, NMEA interface, remote display, and water sampler).

Follow these steps to get started using SEASAVE to display archived data:

1	In the File menu, select Open SEASAVE Configuration. The Select SEASAVE Configure File to Use dialog box appears. Browse to the desired file
(default location C:\Program Files\Sea-Bird\SS-WIN32-DEMO),
select one of the .cfg files, and click OK. The display windows will now correspond to the selected .cfg file.

2	In the ArchivedData menu, select Start.

3	The Start Archived Data Display dialog box appears.

A.	Click Select Data File. The Select Data File dialog box appears. Browse to the desired file
(default location C:\Program Files\Sea-Bird\SS-WIN32-DEMO\demo.dat)
and click OK.

B.	Click Select .con File: The Select Instrument Configuration File dialog box appears. Browse to the desired file
(default location C:\Program Files\Sea-Bird\SS-WIN32-DEMO\demo.con)
and click OK.

C.	Click Start Display. The example data will display.

4	As desired, modify and save the setup of the display windows, save the modified .cfg file, and repeat Steps 2 and 3.

NOTE

When modifying and saving the display window setup files and SEASAVE configuration (.cfg) file, use new file names to avoid overwriting the demo files.

To Acquire and Display 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:

•	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

•	Alarms -- enable and set up altimeter alarm in Deck Unit (if altimeter integrated with instrument) and/or SBE 14 Remote Display alarm (if SBE 14 connected to a computer COM port).

•	ASCII Output -- enable and set up output of ASCII data (converted data in engineering units) to a COM port on your computer or to a shared file on your computer

•	Header -- create a customized header for the data

•	Mark Variable Selection -- set up format for marking of selected scans of data

•	NMEA Lat/Lon Interface -- define what navigation data is written to the data file

•	Remote Display -- enable and set up output of data to an SBE 14 Remote Display (if SBE 14 connected to a computer COM port).

•	Water Sampler Configuration -- enable and set up control of bottle firing for a water sampler

2	Define SEASAVE displays. SEASAVE can have up to 10 displays total. Three types are available: fixed, scrolled, and overlay (plot) displays.

3	Start real-time data acquisition. If applicable (and if enabled in Step 1), fire bottles, mark scans, and / or send Lat/Lon data to a file during acquisition.


Command Line Operation

SEASAVE has several command line parameters, for infrequently used options.

Command Line Parameter	Function
-autostart= filename	Automatically start SEASAVE and data acquisition, saving data to filename. Filename must include path and extension (.dat for SBE 9plus; .hex for SBE 16, 16plus, 19, 19plus, 21, 25, or 31). SEASAVE uses .con file and display setup from last saved SEASAVE configuration (.cfg). This allows you to set up system ahead of time, and then have an untrained operator start acquisition without navigating through SEASAVE’s menus.
-diffd2	Add (secondary sensor sigma-2) - (primary sensor sigma-2) to list of variables for display.
-pc	Enable pump on/off control for SBE 911plus from within SEASAVE. Turn Pump On and Turn Pump Off selections in RealtimeData menu remain grayed out if this parameter is not used.
-wsN	Change time to wait for movement of magnetic switch from off to on (for SBE 19, 19plus, and 25) from default 90 seconds to N seconds. After you start real-time data acquisition, SEASAVE waits up to N seconds for you to turn instrument’s magnetic switch on before timing out.
-ss	Automatically start SEASAVE and data display, but do not save data until user responds to save prompt. SEASAVE uses .con file and display setup from last saved SEASAVE configuration (.cfg). This allows you to view, but not save, data acquired during soak time, eliminating the need to edit the data file later to remove these scans.
-nmeatime	For NMEA navigation device messages that contain time but not date, this parameter affects NMEA UTC Time in data file header and NMEA date/time in NMEA Data dialog box on screen during data acquisition. See description below.
NOTE: If specifying multiple parameters, insert a space between each parameter in the list.

For the -nmeatime command line parameter:

If NMEA Message Includes	-nmeatime Included in Command Line?	Information in NMEA UTC Time in Header	Information in NMEA Data dialog box on screen
Date & time	(no effect)	NMEA time & date	NMEA time & date
Time only	No	(none)	NMEA time only
Time only	Yes	NMEA time	NMEA time & computer date
No date or time	(no effect)	(none)	(none)
NOTES

•	To view NMEA Data dialog box: In the View menu, select NMEA Data Display.

•	System Upload Time in the data file header is always computer time and date, regardless of whether a NMEA navigation device is transmitting data.

To Run SEASAVE with a Command Line Parameter

1	In the Windows Start menu, select Run. The Run dialog box appears. Enter the command line parameter(s) as shown below:
     Path\seasave.exe parameter1 parameter2 .  .  .  .  .
where Path is the location of seasave.exe on your computer, and 1 or more command line parameters are listed.
Examples:

•	"C:\Program Files\Sea-Bird\seasave.exe" -pc -diffd2 -ws180     (enables 3 parameters shown)

•	"C:\Program Files\Sea-Bird\seasave.exe" -pc      (enables 1 parameter shown)

•	"C:\Program Files\Sea-Bird\seasave.exe" –autostart="C:\Test Directory\testdata.hex"      (automatically starts SEASAVE and data acquisition, saving data to C:\Test Directory\testdata.hex)

2	SEASAVE opens. Set up the system and displays as desired. The functions specified by the command line parameters are enabled.

NOTES

•	If the path includes any spaces, enclose the path in quotes ("path"). See the examples above.

•	An alternative method of running SEASAVE with a Command Line Parameter is from a command prompt.


Processing Data

Sea-Bird provides software, SBE Data Processing, for converting the raw .hex or .dat 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 .hex or .dat data file before beginning processing, to remove data at the beginning of the file corresponding to instrument soak time, to remove blocks of bad data, to edit the header, or to add explanatory notes about the cast. Editing the raw .hex or .dat file can corrupt the data, making it impossible to perform further processing using Sea-Bird software. Sea-Bird strongly recommends that you first convert the data to a .cnv file (using the Data Conversion module in SBE Data Processing), and then use other SBE Data Processing modules to edit the .cnv file as desired.

.hex Files

The procedure for editing a .hex data file described below has been found to work correctly on computers running Windows 98, 2000, and NT. If the editing is not performed using this technique, SBE Data Processing may reject the edited data file and give you an error message.

NOTE

Although we provide this technique for editing a raw .hex file, Sea-Bird’s strong recommendation, as described above, is to always convert the raw data file and then edit the converted file.

1	Make a back-up copy of your .hex data file before you begin.

2	Run WordPad.

3	In the File menu, select Open. The Open dialog box appears. For Files of type, select All Documents (*.*). Browse to the desired .hex data file and click Open.

4	Edit the file as desired, inserting any new header lines after the System Upload Time line. Note that all header lines must begin with an asterisk (*), and *END* indicates the end of the header. An example is shown below, with the added lines in bold:

* Sea-Bird SBE 21 Data File:

* FileName = C:\Odis\SAT2-ODIS\oct14-19\oc15_99.hex

* Software Version Seasave Win32 v1.10

* Temperature SN = 2366

* Conductivity SN = 2366

* System UpLoad Time = Oct 15 1999  10:57:19

* Testing adding header lines

* Must start with an asterisk

* Place anywhere between System Upload Time & END of header

* NMEA Latitude = 30 59.70 N

* NMEA Longitude = 081 37.93 W

* NMEA UTC (Time) = Oct 15 1999  10:57:19

* Store Lat/Lon Data = Append to Every Scan and Append to .NAV File When <Ctrl F7> is Pressed

** Ship:       Sea-Bird

** Cruise:     Sea-Bird Header Test

** Station:

** Latitude:

** Longitude:

*END*

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.

.dat Files

Sea-Bird is not aware of a technique for editing a .dat file that will not corrupt it. Opening a .dat file with any text editor corrupts the file by leaving behind invisible characters (for example, carriage returns, line feeds, etc.) when the file is closed. These characters, inserted semi-randomly through the file, corrupt the data format. Sea-Bird distributes a utility program with the software called Fixdat that may repair a corrupted .dat file.

•	Fixdat.exe is installed with, and located in the same directory as, SBE Data Processing (the data processing software in our Windows suite of software).


Derived Parameter Formulas

For formulas for the calculation of conductivity, temperature, and pressure, see the calibration sheets for your instrument.

Formulas for the computation of salinity, density, potential temperature, specific volume anomaly, and sound velocity were obtained from "Algorithms for computation of fundamental properties of seawater", by N.P. Fofonoff and R.C Millard Jr.; Unesco technical papers in marine science #44, 1983.

•	Temperature used for calculating derived variables is IPTS-68. Following the recommendation of JPOTS, T68 is assumed to be 1.00024 * T90 (-2 to 35 °C).

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.

Equations are provided for the following oceanographic parameters:

•	density (density, sigma-theta, sigma-t, sigma-1, sigma-2, sigma-4)

•	thermosteric anomaly

•	specific volume

•	specific volume anomaly

•	geopotential anomaly

•	dynamic meters

•	depth (salt water, fresh water)

•	salinity

•	sound velocity (Chen-Millero, DelGrosso, Wilson)

•	average sound velocity

•	potential temperature (reference pressure = 0.0 decibars)

•	potential temperature anomaly

•	specific conductivity

•	derivative variables (descent rate and acceleration) -- if input file has not been averaged into pressure or depth bins

•	oxygen (if input file contains pressure, temperature, and either conductivity or salinity, and has not been averaged into pressure or depth bins) -- also requires oxygen current and oxygen temperature (for SBE 13 or 23) or oxygen signal (for SBE 43)

•	corrected irradiance (CPAR)

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.

•	In Derive, the algorithm is based on the assumption that the data has been bin averaged already. Average sound velocity is computed scan-by-scan:
d i = depth of current scan – depth of previous scan      [meters]
v i = sound velocity of this scan (bin)     [m/sec]

•	In SEASAVE and Data Conversion, the algorithm also requires user input of a pressure window size and time window size. It then calculates:
d i = depth at end of window – depth at start of window      [meters]
v i = (sound velocity at start of window + sound velocity at end of window) / 2     [m/sec]

(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).

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. SEASAVE and Data Conversion compute the derivative looking backward in time, since they share common code and SEASAVE cannot use future values of pressure while acquiring data in real time. Derive uses a centered window (equal number of points before and after the scan; time window size is user-input) to obtain a better estimate of the derivative. Use SEASAVE and Data Conversion to obtain a quick look at descent rate and acceleration; use Derive to obtain the most accurate values.

NOTE

In the View menu, select Toolbar to display or hide the Toolbar.


Open/Save SEASAVE Configuration

The SEASAVE configuration file contains:

•	information on size, placement, update rate, and setup file name (with a .dsf, .dso, or .dss extension) for each display window within the SEASAVE window. Note that the setup files define what parameters are displayed and how they are displayed (overlay plot, fixed display, or scrolled display).

•	the name of the instrument configuration (.con) file, which defines the number and type of sensors, and the sensor calibration coefficients.

•	other system configuration information -- setup for alarms, ASCII output, header, mark scans, NMEA interface, remote display, and water sampler.

The SEASAVE configuration file has a .cfg extension.

To Save SEASAVE Configuration File

1	If you have not already done so, save each SEASAVE display window setup as follows:

A.	Right click in the display window and select Setup.

B.	In the Display Setup dialog box, click Save Display File.

C.	In the Select Display File to Save to dialog box, select/enter the desired file name and location, and click OK. File extensions for display setup files vary, depending on the display type: .dso extension for overlay (X-Y) displays, .dsf extension for fixed displays, and .dss extension for scrolled displays.

D.	In the Display Setup dialog box, click OK to exit the dialog box.

2	From the File menu, select Save SEASAVE Configuration As. In the Select SEASAVE Configure File to Save dialog box, select/enter the desired file name and location, and click OK. The file has a .cfg extension.

To Open SEASAVE Configuration File

1	From the File menu, select Open SEASAVE Configuration. In the Select SEASAVE Configure File to Use dialog box, select the desired file name and location, and click OK. The file has a .cfg extension.


Print

SEASAVE’s Print function prints the currently selected display window.

To Print

1	Click in the desired window.

2	From the File menu, select Print. The standard Windows Print dialog box appears; set up the print job as desired and click OK.


Alarms

SEASAVE can set up two types of alarms:

•	An alarm in the Deck Unit for an altimeter integrated with the CTD, and/or

•	An alarm on the SBE 14 Remote Display

To Enable and Set Up Altimeter Alarm

1	In the Configure menu, set up the CTD configuration (.con) file as desired. Select the altimeter as one of the auxiliary voltage sensors. Save the changes.

2	In the Configure menu, select Alarms / Altimeter Alarm. In the Altimeter Alarm Configuration dialog box, select Enable Altimeter Alarm. Enter the alarm parameters (see diagram below) and click OK.

NOTES

•	Sea-Bird recommends Minimum Pressure to Enable Altimeter Alarm > 20 decibars to prevent the alarm from turning on while on the ship deck or as the system is entering the water.

•	Set Alarm Hysteresis greater than the expected ship heave (swell) to prevent on-off-on-off sounding of the alarm caused by ship heave.
Example: You want the alarm to turn on at 10 meters; set Alarm Setpoint = 10 meters. There is a 0.5 meter swell; set Alarm Hysteresis =1 meter, which should be sufficient to account for possible 0.5 meter upward movement due to ship heave. The alarm will sound at 10 meters and will stay on until the altimeter goes above 11 meters, when it will shut off until it falls to 10 meters again.

To Enable and Set Up Remote Display Alarm

The SBE 14 Remote Display can be set up to turn an alarm on when pressure is less than a specified amount and/or when pressure is more than a specified amount.

To enable and set up the Remote Display Alarm:

1	In the Configure menu, select Remote Display.

2	In the Remote Display Configuration dialog box, select Send Data to SBE 14 Display. Make other selections as desired, and click OK.

3	In the Configure menu, select Alarms / Remote Display Alarm. In the Remote Display Alarm Configuration dialog box, select the desired alarm (minimum pressure alarm and/or maximum pressure alarm) and enter the alarm set points in decibars. Click OK.

NOTES

•	Alarm setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the setup, you must save the .cfg file before exiting SEASAVE.

•	Remote Display alarm setup in SEASAVE is applicable only for an SBE 14 connected to a computer COM port. 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.


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. However, the data you are viewing will not refresh while the ASCII file is open; in other words, you must close the file and reopen it to view the latest data.

To Enable and Set Up ASCII Data Output

1	In the Configure menu, select ASCII Output. The ASCII Output Set Up dialog box appears:

2	Select Output ASCII Data to COM or Generate Shared File.

•	If you selected Output ASCII Data to COM -- Select the ASCII Data Output Port (COM1 through COM10 are available). Click Comm Settings. The Communication Settings dialog box appears. Select the baud rate, data bits, and parity for the output data, and click OK.

•	If you selected Generate Shared File -- Click Shared File. The Select or Enter Shared File Name dialog box appears. Browse to the desired location, enter the desired file name, and click Open.

3	Enter the number of seconds between ASCII updates, which controls how often data for the selected variables is converted to engineering units and sent to the COM port. The time between ASCII updates interacts with the instrument’s data output baud rate and the number of output variables selected. SEASAVE will not work properly if data is presented to the COM port faster than the COM port can transmit it at the selected baud rate. For full rate data, set to 0.

4	Select the desired variable for each column of data by clicking Select Variable. A dialog box with a list of variables appears; make your selection and click OK. Enter the number of desired digits after the decimal point for each variable’s data.

5	Click OK.

NOTE

ASCII Output setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the setup, you must save the .cfg file before exiting SEASAVE.


Header Form

SEASAVE can write a user-input descriptive header to the data file, which is useful in identifying the data set. There are three choices for header use:

•	Prompt for header information -- The user will be prompted to fill out the header form at the start of data acquisition. Only the lines with text prompts on them will appear. The completed header, along with system time, instrument type, and serial numbers, will be written to the beginning of the data file and also output to a file with the same name as the data file but with a .hdr extension.

•	Include Default Header Information in File -- The user will not be prompted to add any header information at the start of data acquisition. The user-defined default header form will be written as-is to the beginning of the data file and also output to a file with the same name as the data file but with a .hdr extension.

•	Don’t Include Header Information in File – User-input header information will not be added to the data file or placed in a .hdr file.

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. The second, UTC Time, is the date and time from an optional NMEA navigation device.

To Set Up Header

1	In the Configure menu, select Header Form.

2	In the Header Form Setup dialog box, select the desired Header Choice and enter the header. Click OK.

Example:

Prompt for Header Information is selected in the Header Form Setup dialog box, and the Header Form prompts are filled in as shown.

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.

NOTE

Header setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the entire setup, you must save the .cfg file before exiting SEASAVE.


Mark Variable Selection

Mark Scan allows you to copy the most recent scan of data to a mark (.mrk) file as desired. The .mrk file can be used to manually note water sampler bottle firings, to compare CTD data with data from a Thermosalinograph taken at the same time, or to mark significant events in the cast (winch problems, large waves causing ship heave, etc.) for later review and analysis of the data.

If a plot display is set up to show mark lines, SEASAVE will also draw a horizontal line in the plot each time you mark a scan.

NOTE

The .mrk file has the same file name as the data file. For example, if the data file is test1.hex, the .mrk file is test1.mrk.

To Enable and Set Up Mark Variables

1	In the Configure menu, select Mark Variable Selection. The Mark Variable Configuration dialog box appears:

2	In the Mark Variable Configuration dialog box, select:

•	mark type (line can be labeled with the sequential mark number or with the pressure), line style, and color -- applicable only if you set up a plot display to show mark lines in Step 3 below.

•	mark variables and digits after the decimal point -- the sequential mark number, system time, and selected variables are written to the .mrk file each time Mark Scan is clicked during data acquisition

Click OK.

3	To set up a plot display to show mark lines -- Right click in the desired Overlay plot window, and select Setup. In the Display Setup dialog box, select Show Mark Lines. Change other settings as desired, and click OK.

4	See Mark Scan Control to mark the scans during real-time data acquisition.

NOTE

Mark Variable setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the entire setup, you must save the .cfg file before exiting SEASAVE.


NMEA Lat/Lon Interface

If your instrument is connected to a deck unit that can integrate data from a NMEA navigation device with the CTD data, NMEA Lat/Lon Interface defines what navigation data is written to the data file. Note that NMEA data is written to the data file only if the instrument configuration (.con) file indicates that NMEA data is to be added (see Instrument Configuration).

NOTES

•	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. The second, UTC Time, is the date and time from an optional NMEA navigation device.

•	NMEA Lat/Lon Interface selections are not applicable to the SBE 45. The 90402 – SBE 45 Interface Box defines what navigation data is included in the data file.

To Set Up NMEA Lat/Lon Interface

1	In the Configure menu, set up the CTD configuration (.con) file as desired. Select NMEA data added in the instrument Configuration dialog box. Save the changes.

2	In the Configure menu, select NMEA Lat/Lon Interface. The NMEA Interface Configuration dialog box appears. Select how to store the data:

•	Add to Header Only: Latitude, longitude, and time are automatically written to the header when data acquisition is started.

•	Append to Every Scan: Latitude, longitude, and time are automatically written to the header when data acquisition is started. Additionally, 7 bytes of Lat/Lon data are appended to every scan of CTD data.
Note: For the SBE 21, if NMEA depth data added is selected in the .con file, 3 bytes of depth data is also appended to every scan of CTD data, after the Lat/Lon data.

•	Append to .nav File when <Ctrl F7> is Pressed: Latitude, longitude, and time are automatically written to the header when data acquisition is started. And, latitude, longitude, time, scan number, and pressure are written to a .nav file every time Add to .nav File is selected (see Add to .nav File or NMEA Data Display).

•	Append to Every Scan and Append to .nav File when <Ctrl F7> is Pressed: Latitude, longitude, and time are automatically written to the header when data acquisition is started. Additionally, 7 bytes of Lat/Lon data are appended to every scan of CTD data. And, latitude, longitude, time, scan number, and pressure are written to a .nav file every time Add to .nav File is selected (see Add to .nav File or NMEA Data Display).
Note: For the SBE 21, if NMEA depth data added is selected in the .con file, 3 bytes of depth data is also appended to every scan of CTD data, after the Lat/Lon data.

3	Click OK.

NOTES

•	NMEA Lat/Lon Interface setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the setup, you must save the .cfg file before exiting SEASAVE.

•	When running Data Conversion in SBE Data Processing, if a .nav file is found in the same directory as the data file (and with the same name), the contents of the .nav file are added to the converted data file header.


Remote Display

The SBE 14 Remote Display can display depth, pressure, and/or altimeter height for a CTD system.

To Enable and Set Up Remote Display

1	In the Configure menu, select Remote Display. The Remote Display Configuration dialog box appears:

2	In the Remote Display Configuration dialog box, select Send Data to SBE 14 Remote Display.

3	Select Remote Display Data Type. Choices are:

•	Depth -- displays with 4 digits

•	Pressure -- displays with 4 digits

•	Altimeter Height with Depth -- altimeter height and depth alternate on display; altimeter height displays with 3 digits and depth displays with 4 digits

•	Altimeter Height with Pressure -- altimeter height and pressure alternate on display; altimeter height displays with 3 digits and pressure displays with 4 digits

4	Select water type: fresh or salt water. Water type affects the program’s calculation of depth.

5	Select Remote Display Output Port. COM ports 1 through 10 are available.

6	Enter the Number of Seconds between Remote Display Updates. Updates at a very fast rate could make the display difficult to read. Additionally, the time between updates interacts with the data output baud rate (set internally in the SBE 14 to 300 baud; cannot be changed) and the number of variables transmitted. SEASAVE will not work properly if data is presented to the COM port faster than the COM port can transmit it to the SBE 14 at 300 baud.

7	Click OK.

•	To set up the SBE 14’s alarm, see Alarms.

•	Remote Display setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the entire setup, you must save the .cfg file before exiting SEASAVE.

•	Remote Display setup in SEASAVE is applicable only for an SBE 14 connected to a computer COM port. If the SBE 14 is connected directly to an SBE 11plus Deck Unit, Remote Display setup is done by sending commands to the SBE 11plus using SEATERM.


Water Sampler Configuration

For real-time data acquisition, a Sea-Bird CTD can be integrated with a water sampler when used with a deck unit. The water sampler bottles can be fired by command from SEASAVE (see Fire Bottle Control).

Bottle firings can be recorded in the data in several ways:

•	SEASAVE automatically writes bottle sequence number, bottle position, date, time, and beginning and ending scan numbers to a bottle log (.bl) file each time a bottle fire confirmation is received from the water sampler. The beginning and ending scan numbers correspond to approximately a 1.5-second duration for each bottle.

•	 For a 911plus system, SEASAVE automatically sets the bottle confirm bit in the data (.dat) file for all scans within a 1.5-second period after a bottle firing confirmation is received from the water sampler.

•	If desired, you can use SEASAVE’s Mark Scan feature to manually note when bottles are fired, creating a .mrk file.

SBE Data Processing can use the bottle firing information, in any of these forms, to assist you in processing the water bottle data.

To Enable and Set Up Water Sampler

1	In the Configure menu, select Water Sampler Configuration. The Water Sampler Configuration dialog box appears:

2	Select the number of bottles and water sampler type (none, GO 1015, GO 1016, Hydro-Bios, IOW, SBE Carousel).

3	Select the Firing Sequence:

•	Sequential -- When commanded to fire, bottles are fired in order of position (bottle in position #1 fired first, bottle in position #2 fired second, etc.).

•	User input -- When commanded to fire, SEASAVE prompts you to select which bottle to fire.

•	Table driven -- When commanded to fire, bottles are fired in order pre-defined by user-input table. Click Bottle Positions for Table Driven to input the bottle positions.

4	Click OK.

NOTES

•	See Fire Bottle or Fire Bottle Control for details on firing the bottles during real-time data acquisition.

•	Water Sampler setup, along with setup of other parameters in the Configure menu, is included in the SEASAVE configuration (.cfg) file. To save the entire setup, you must save the .cfg file before exiting SEASAVE.


Instrument Configuration Introduction

The instrument configuration (.con) file defines the instrument configuration (what sensors are integrated with the instrument and what channels are used by the sensors) and the sensor calibration coefficients. SEASAVE uses this information to convert the raw data stream into engineering units for display during real-time data acquisition.

Because Sea-Bird always tries to maintain support for old instrumentation, while continuously improving and expanding our product line, SEASAVE has two instrument configuration types:

•	Old Style Instrument Configuration -- does not support products or auxiliary sensors added to software after November 2000 (such as SBE 16plus or 19plus SEACAT, SBE 45 MicroTSG, SBE 49 FastCAT, SBE 43 Dissolved Oxygen Sensor, and Turner SCUFA).

•	New Style Instrument Configuration -- does not support older products: SBE 3, SBE 911, or 911e (but does support 9plus with 11plus or 17plus, abbreviated in SEASAVE as 911/917plus). The new style has the same features / functions / dialog boxes as used by our Windows data processing software (SBE Data Processing), and is the style required by SBE Data Processing.

Old and new styles are compatible, except for the instruments / sensors that are not supported. This allows you to open an existing old style .con file with the new style selection in the Configure menu, and vice versa, if the instrument and sensors are all supported by that style.

•	Use the new style if your system does not include any of the older instruments and you plan to use SBE Data Processing to process the data after acquisition. Note that this .con file can be created / modified in SEASAVE or SBE Data Processing.

•	Use the old style if your system includes any of the older instruments or you plan to use SEASOFT-DOS to process the data after acquisition. Note that this .con file can be created / modified in SEASAVE or in the SEACON module of SEASOFT-DOS.

The .con file discussion is in six parts:

•	Old Style Instrument Configuration discusses the Old Style Configuration dialog box for each instrument - number and type of sensors on the instrument, etc.

•	New Style Instrument Configuration discusses the New Style Configuration dialog box for each instrument - number and type of sensors on the instrument, etc.

•	Calibration Coefficients - Frequency Sensors discusses calculation of coefficients for each type of frequency sensor (temperature, conductivity, Digiquartz pressure, IOW sound velocity, etc.).

•	Calibration Coefficients - A/D Count Sensors discusses calculation of coefficients for A/D count sensors (temperature and strain gauge pressure) used on the SBE 16plus, 19plus, and 49.

•	Calibration Coefficients - Voltage Sensors discusses calculation of coefficients for each type of voltage sensor (strain gauge pressure, oxygen, pH, etc.).

•	Format of .con File contains a line-by-line description of the contents of the .con file, which can be viewed in a text editor.

NOTE

Sea-Bird supplies a .con file with each instrument. The .con file must match the existing instrument configuration and contain current sensor calibration information.


Old Style Instrument Configuration

The instrument configuration (.con) file defines the instrument configuration (what sensors are integrated with the instrument and what channels are used by the sensors) and the sensor calibration coefficients. SEASAVE uses this information to convert the raw data stream into engineering units for display during real-time data acquisition.

Old Style Instrument Configuration does not support products or auxiliary sensors added to software after November 2000 (such as SBE 16plus and SBE 19plus SEACAT, SBE 45 MicroTSG, SBE 49 FastCAT, SBE 43 Dissolved Oxygen Sensor, and Turner SCUFA).

•	Use the old style if your system does not include any of these newer instruments / sensors, and if you plan to use SEASOFT-DOS for data processing.

•	If your system includes newer instruments / sensors, or you plan to use SBE Data Processing (Windows software) for data processing, use the new style instrument configuration.

NOTE

Unless noted otherwise, SEASAVE supports only one of each brand and type of auxiliary sensor interfacing with a CTD. For example, it does not support two Chelsea Minitracka fluorometers, but it does support a Chelsea Minitracka and a Chelsea Aqua 3 fluorometer. SEASAVE’s Old Style Instrument Configuration will not give you an error message if you select two or more of the same sensor; however, it will use the calibration coefficients of the first sensor for all identical sensors. See the individual sensor descriptions in Calibration Coefficients - Voltage Sensors for those sensors that SEASAVE does support in a redundant configuration (two or more of the same sensor interfacing with the CTD) when using the Old Style Configuration.

New Style Instrument Configuration

The instrument configuration (.con) file defines the instrument configuration (what sensors are integrated with the instrument and what channels are used by the sensors) and the sensor calibration coefficients. SEASAVE uses this information to convert the raw data stream into engineering units for display during real-time data acquisition.

New Style Instrument Configuration does not support older products: SBE 31, SBE 911 or 911e (but does support 9plus with 11plus or 17plus, abbreviated in SEASAVE as 911/917plus).

•	Use the new style if your system does not include any of these older instruments, and if you plan to use SBE Data Processing (Windows software) for data processing.

•	If your system includes any of these older instruments, or you plan to use SEASOFT-DOS for data processing, use the old style instrument configuration.

NOTE

Unless noted otherwise, SEASAVE supports only one of each brand and type of auxiliary sensor (for example, you cannot specify two Chelsea Minitracka fluorometers, but you can specify a Chelsea Minitracka and a Chelsea UV Aquatracka fluorometer). See the individual sensor descriptions in Calibration Coefficients - Voltage Sensors for those sensors that SEASAVE supports in a redundant configuration (two or more of the same sensor interfacing with the CTD) when using the New Style Configuration.

Calibration Coefficients - Frequency Sensors

SEASAVE uses the sensor calibration coefficients to convert the raw data stream into engineering units for display during real-time data acquisition.

The method for accessing the calibration coefficients to view or modify them is dependent on whether you are using the Old Style Instrument Configuration or New Style Instrument Configuration, and is summarized below:

•	Old Style Instrument Configuration -- In Configure menu, select Old Style Instrument Configuration. Click Select [.con] File; browse to desired file. Click Examine/Change[.con] File. Click Change Calibration Coefficients. Double click on desired sensor; the calibration coefficients dialog box for the sensor appears.

•	New Style Instrument Configuration -- In Configure menu, select New Style Instrument Configuration / Select Instrument Configuration; browse to desired file. In Configure menu, select New Style Instrument Configuration / Modify Selected Instrument Configuration. Double click on desired sensor; the calibration coefficients dialog box for the sensor appears.

For all calibration coefficient dialog boxes, enter the sensor serial number and calibration date. Many sensor calibration equations contain an offset term. Unless noted otherwise, use the offset (default = 0.0) to make small corrections for sensor drift between calibrations.

The following types of frequency sensors are available (not all frequency sensors are applicable to all instruments): temperature, conductivity, pressure (Paroscientific Digiquartz), bottles closed (IOW), and sound velocity (IOW).

Temperature Calibration Coefficients

Enter g, h, i, j, (or a, b, c, d), and f0 from the calibration sheet.

Enter values for slope (default = 1.0) and offset (default = 0.0) to make small corrections for temperature sensor drift between calibrations:

Corrected temperature = (slope * computed temperature) + offset
where
slope = true temperature span / instrument temperature span
offset = (true temperature – instrument reading) * slope; measured at 0 °C

Temperature Slope and Offset Correction Example

At true temperature = 0.0 °C, instrument reading = 0.0015 °C

At true temperature = 25.0 °C, instrument reading = 25.0005 °C

Calculating the slope and offset:

Slope = (25.0 – 0.0) / (25.0005 – 0.0015) = + 1.000040002

Offset = (0.0 – 0.0015) * 1.000040002 = - 0.001500060

NOTES

1	Coefficients g, h, i, j, and f0 provide ITS-90 (T90) temperature; a, b, c, d, and f0 provide IPTS-68 (T68) temperature. The relationship between them is: T68 = 1.00024 T90

2	See Application Note 31 on our website for computation of slope and offset correction coefficients from pre- and post-cruise calibrations supplied by Sea-Bird.

Sea-Bird temperature sensors usually drift by changing offset, typically resulting in higher temperature readings over time for sensors with serial number less than 1050 and lower temperature readings over time for sensors with serial number greater than 1050. Sea-Bird’s data indicates that the drift is smooth and uniform with time, allowing users to make very accurate corrections based only on pre- and post-cruise laboratory calibrations. Calibration checks at sea are advisable to ensure against sensor malfunction; however, data from reversing thermometers is rarely accurate enough to make calibration corrections that are better than those possible from shore-based laboratory calibrations.

Sea-Bird temperature sensors rarely exhibit span errors larger than ± 0.005 °C over the range –5 to +35 °C (0.005 °C/(35 -[-5])C/year = 0.000125 °C/C/year), even after years of drift. A span error that increases more than ± 0.0002 °C/C/year may be a symptom of sensor malfunction.

NOTE

See Calibration Coefficients for A/D Count Sensors for information on temperature sensors used in SBE 16plus, 19plus, and 49.

Conductivity Calibration Coefficients

Enter g, h, i, j, and Ctcor (or a, b, c, d, and m) and Cpcor from the calibration sheet.

NOTE

Use coefficients g, h, i, j, Ctcor, and Cpcor (if available on calibration sheet) for most accurate results; conductivity for older sensors was calculated based on a, b, c, d, m, and Cpcor.

Cpcor makes a correction for the highly consistent change in dimensions of the conductivity cell under pressure. The default is the compressibility coefficient for borosilicate glass (-9.57e-08). Some sensors fabricated between 1992 and 1995 (serial numbers between 1100 and 1500) exhibit a compression that is slightly less than pure borosilicate glass. For these sensors, the (hermetic) epoxy jacket on the glass cell is unintentionally strong, creating a composite pressure effect of borosilicate and epoxy. For sensors tested to date, this composite pressure coefficient ranges from -9.57e-08 to -6.90e-08, with the latter value producing a correction to deep ocean salinity of 0.0057 PSU in 5000 dbars pressure (approximately 0.001 PSU per 1000 dbars).
Before modifying Cpcor from its default value, confirm that the sensor behaves differently from pure borosilicate glass. Sea-Bird can test your cell and calculate Cpcor. Alternatively, test the cell by comparing computed salinity to the salinity of water samples from a range of depths, calculated using an Autosal.

Enter values for slope (default = 1.0) and offset (default = 0.0) to make small corrections for conductivity sensor drift between calibrations:

Corrected conductivity = (slope * computed conductivity) + offset
where
slope = true conductivity span / instrument conductivity span
offset = (true conductivity – instrument reading) * slope; measured at 0.0 S/m

Conductivity Slope and Offset Correction Example

At true conductivity = 0.0 S/m, instrument reading = -0.00007 S/m

At true conductivity = 3.5 S/m, instrument reading = 3.49965 S/m

Calculating the slope and offset:

Slope = (3.5 – 0.0) / (3.49965 - [- 0.00007]) = + 1.000080006

Offset = (0.0 - [-0.00007]) * 1.000080006 = + 0.000070006

NOTE

See Application Note 31 on our website for computation of slope and offset correction coefficients from pre- and post-cruise calibrations supplied by Sea-Bird or from salinity bottle samples taken at sea during profiling.

The sensor usually drifts by changing span (slope of the calibration curve), typically resulting in lower conductivity readings over time. Offset error (error at 0 S/m) is usually due to electronics drift, and is typically less than ± 0.0001 S/m per year. Because offsets greater than ± 0.0002 S/m are a symptom of sensor malfunction, Sea-Bird recommends that drift corrections be made by assuming no offset error, unless there is strong evidence to the contrary or a special need.

Wide Range Conductivity Sensors

A wide range conductivity sensor has been modified to provide conductivity readings to 15 Siemens/meter by inserting a precision resistor in series with the conductivity cell. Therefore, the equation used to fit the calibration data is different from the standard equation. The sensor’s High Range Conductivity Calibration sheet includes the equation as well as the cell constant and series resistance to be entered in the program.

If the conductivity sensor serial number includes a w (an indication that it is a wide range sensor):

Calibration Coefficients - A/D Count Sensors

SEASAVE uses the sensor calibration coefficients to convert the raw data stream into engineering units for display during real-time data acquisition.

In Configure menu, select New Style Instrument Configuration / Modify Selected Instrument Configuration. Double click on desired sensor; the calibration coefficients dialog box for the sensor appears.

For all calibration coefficient dialog boxes, enter the sensor serial number and calibration date. Many sensor calibration equations contain an offset term. Unless noted otherwise, use the offset (default = 0.0) to make small corrections for sensor drift between calibrations.

The following types of A/D count sensors are used with the SBE 16plus, 19plus, and 49: temperature and strain gauge pressure.

Temperature Calibration Coefficients

Enter a0, a1, a2, and a3 from the calibration sheet.

Enter values for slope (default = 1.0) and offset (default = 0.0) to make small corrections for temperature sensor drift between calibrations:

where
slope = true temperature span / instrument temperature span
offset = (true temperature – instrument reading) * slope; measured at 0 °C

Temperature Slope and Offset Correction Example

At true temperature = 0.0 °C, instrument reading = 0.0015 °C

At true temperature = 25.0 °C, instrument reading = 25.0005 °C

Calculating the slope and offset:

Slope = (25.0 – 0.0) / (25.0005 – 0.0015) = + 1.000040002

Offset = (0.0 – 0.0015) * 1.000040002 = - 0.001500060

NOTES

1	Enter soc and boc values from the most recent field calibration for Beckman-type, YSI-type, or Sea-Bird oxygen sensor.

2	Oxygen values computed by SEASAVE and SBE Data Processing’s Data Conversion module differ from values computed by SBE Data Processing’s Derive module. Both algorithms use the derivative of the oxygen signal with respect to time:

•	Quick estimate -
SEASAVE and Data Conversion compute the derivative looking back in time, because they share common code and SEASAVE cannot use future values while acquiring real-time data.

•	Most accurate results -
Derive uses a centered window (equal number of points before and after scan) to compute the derivative.

Enter the coefficients, which vary depending on the type of oxygen sensor, from the calibration sheet:

See Application Notes 11 QSP-L (Biospherical sensor with built-in log amplifier) and 11-QSP-PD (Biospherical sensor without built-in log amplifier) on our website for complete description of calculation of calibration coefficients.

•	LI-COR PAR sensor
Calibration constant is LI-COR in water calibration constant from calibration sheet. Enter calibration constant, M, and B from calibration sheet.
See Application Note 11 LICOR on our website for complete description of calculation of calibration coefficients.

•	Chelsea PAR sensor  (select PAR/Irradiance, Biospherical/Licor in .con file)
Calibration constant
= 10^9 / 0.01   (for units of microEinsteins/sec–m2)  or
= 10^9 / 0.04234   (for units of quanta/sec–m2)
M = 1.0 / (log e * A1 * 1000) = 1.0 / (0.43429448 * A1 * 1000)
B = - M * log e * A0 = - M * 0.43429448 * A0
where A0 and A1 are constants from Chelsea calibration sheet with an equation of form:
PAR = A0 + A1 * mV

Multiplier can be used to scale output, and is typically set to 1.0.

Note: SEASAVE can process data for an instrument interfacing with up to two PAR/irradiance sensors when using the New Style configuration.

Surface PAR Sensor

A surface PAR sensor is selected by clicking Surface PAR voltage added in the Configure dialog box. Enter conversion factor and ratio multiplier.

See Application Note 11S (11plus Deck Unit) or 47 (SBE 33 or 36 Deck Unit) on our website for complete description of calculation of calibration coefficients for surface PAR.

pH Calibration Coefficients

NOTE

SEASOFT-DOS < version 4.008 ignored temperature compensation of a pH electrode. The relationship between the two methods is:

pH = pH old + (7 – 2087/°K)

For older sensors, run pHfit version 2.0 (included with SEASOFT-DOS) using Vout, pH, and temperature values from the original calibration sheet to compute the new values for offset and slope to enter in the configuration file.

Enter the slope and offset from the calibration sheet:
pH = 7 + (Vout – offset) / (°K * 1.98416e-4 * slope)
where
°K = temperature in degrees Kelvin
See Application Notes 18-1, 18-2, and 18-4 on our website for complete description of calculation of calibration coefficients.

Pressure/FGP (voltage output) Calibration Coefficients

Enter scale factor and offset.
output [Kpa] = (volts * scale factor) + offset

where:

scale factor = 100 * pressure sensor range [bar] / voltage range [volts]

NOTE: SEASAVE can process data for an instrument interfacing with up to eight pressure/fgp sensors when using the New Style or Old Style configuration.

Suspended Sediment Calibration Coefficients

The Sequoia LISST-25 sensor requires two channels – one for scattering output and the other for transmission output. Make sure to select both when configuring the instrument.

For the scattering channel, enter Total volume concentration constant (Cal), Sauter mean diameter calibration (α), Clean H2O scattering output (VS0), and Clean H2O transmission output (VT0) from the calibration sheet. For the transmission channel, no additional coefficients are required; they are all defined for the scattering channel.

Optical transmission = τ = VT / VT0

Beam C  =  - ln (τ) / 0.025              [1 / meters]

Total Volume Concentration = TV = Cal * [ ( VS / τ ) - VS0 ]   [μliters / liter]

Sauter Mean Diameter = SMD = α * [ TV / ( - ln (τ ) ]    [microns]

where

VT = transmission channel voltage output

VS = scattering channel voltage output

The calibration coefficients supplied by Sequoia are based on water containing spherical particles. Perform calibrations using seawater with particle shapes that are similar to what is expected in situ.

Transmissometer Calibration Coefficients

•	Sea Tech, Chelsea (Alphatracka), and WET Labs Cstar
Enter M, B, and path length (in meters)
Path length (distance between lenses) is based on sensor size (for example, 25 cm transmissometer = 0.25m path length, etc.).
light transmission (%) = M * volts + B
beam attenuation coefficient (c) = - (1/z) * ln (light transmission [decimal])
where
M = ( Tw / [ W0 – Y0 ] ) ( A0 – Y0 ) / ( A1 – Y1 )
B = - M * Y1
and
A0 = factory voltage output in air (factory calibration from transmissometer manufacturer)
A1 = current (most recent) voltage output in air
Y0 = factory dark or zero (blocked path) voltage (factory calibration from transmissometer manufacturer)
Y1 = current (most recent) dark or zero (blocked path) voltage
W0 = factory voltage output in pure water (factory calibration from transmissometer manufacturer)
Tw = % transmission in pure water
(for transmission relative to water, Tw = 100%;  or
for transmission relative to air, Tw is defined by table below.)

	Tw = % Transmission in Pure Water (relative to AIR)
Wavelength	10 cm Path Length	25 cm Path Length
488 nm (blue)	99.8%	99.6%
532 nm (green)	99.5%	98.8%
660 nm (red)	96.0 - 96.4%	90.2 - 91.3%
Transmissometer Example

(from calibration sheet) A0 = 4.743 volts, Y0 = 0.002 volts, W0 = 4.565 volts
Tw = 100%  (for transmission relative to water)
(from current calibration) A1 = 4.719 volts and Y1 = 0.006 volts
M = 22.046
B = - 0.132

See Application Note 7 on our website for complete description of calculation of calibration coefficients.

NOTE: SEASAVE can process data for an instrument interfacing with up to two transmissometers in any combination of Sea Tech, Chelsea Alphatracka, and WET Labs Cstar, when using the New Style configuration.

•	WET Labs AC3
This sensor requires two channels - one for fluorometer voltage (listed under fluorometers in the dialog box) and the other for transmissometer voltage (listed under transmissometers). Make sure to select both when configuring the instrument.
Enter Ch2o, Vh2o, VDark, and X from calibration sheet.
Beam attenuation = {[log (Vh2o - VDark) - log (V - VDark)] /X} + Ch2o
Beam transmission (%) = exp ( -beam attenuation * X) * 100

User Polynomial Calibration Coefficients

The user polynomial allows you to define an equation to relate the sensor output voltage to calculated engineering units, if your sensor is not pre-defined in Sea-Bird software.
Enter a0, a1, a2, and a3.
Val = a0 + (a1 * V) + (a2 * V^2) + (a3 * V^3)

where:

V = voltage from sensor

a0, a1, a2, and a3 = user-defined sensor polynomial coefficients

If desired, enter the sensor name. This name will appear in the data file header.

Note: SEASAVE can process data for an instrument interfacing with up to three sensors defined with user polynomials when using the New Style or Old Style configuration.

Wet Labs ECO-FL-NTU Example

For the turbidity channel, NTU = (Vsample – Vblank) * scale factor

Set this equal to user polynomial equation and calculate a0, a1, a2, and a3.

(Vsample – Vblank) * scale factor = a0 + (a1 * V) + (a2 * V2) + (a3 * V3)

Expanding left side of equation and using consistent notation (Vsample = V):

scale factor * V – scale factor * Vblank = a0 + (a1 * V) + (a2 * V2) + (a3 * V3)

Left side of equation has no V2 or V3 terms, so a2 and a3 are 0; rearranging:

(– scale factor * Vblank)  + (scale factor * V) = a0 + (a1 * V)

a0 = – scale factor * Vblank        a1 = scale factor        a2 = a3 = 0

Zaps Calibration Coefficients

Enter M and B from calibration sheet.
z = (M * volts) + B [nmoles]

Add / Edit Display Window

SEASAVE can have up to ten display windows. Edit a display window to select desired parameters, number of digits for data display, and plot characteristics (labels, grids, etc.). This information is saved in a setup file for each display window. File extensions for display setup files vary, depending on display type: .dso for overlay plot displays, .dsf for fixed displays, and .dss for scrolled displays.

To Add a New Display Window

1	In the ScreenDisplay menu, select Add New Display Window and select the window type -- fixed, scroll, or overlay (plot), OR
In the Toolbar, click the New Fixed Display, New Scrolled Display, or New Overlay Display button.

2	The new window appears. Setup of the window display is detailed below.

To Edit a Display Window

1	Click in the desired window.

2	In the ScreenDisplay menu, select Edit Selected Display Window, OR
Right click in the desired window and select Setup. The Display Setup dialog box appears. The selections in the dialog box vary, depending on the display type (see fixed, scrolled, or overlay display below). All three dialog boxes have the following buttons:

•	Select Display File -- select an existing display file for the window.

•	Modify Display Parameters -- modify the existing display setup; brings up a Display Variables Set Up dialog box specific to the display type.

•	Save Display File -- save any changes you make to the display setup.

When you have completed the setup, click OK.

3	Right click in the desired window and select Update Rate. The Change Display Rate dialog box appears. The update rate is the time between each calculation of parameters for update of the display; each display window can have a different update rate. Enter the number of seconds between updates and click OK. Note that an update rate faster than 1 second can be difficult to view on a fixed or scrolled display.

4	If desired, manually change the display window size and location in the SEASAVE window, using standard Windows click-and-drag methods. Or, Auto Arrange the display windows.

NOTE

The display window size and location in the SEASAVE window, and the window update rate, is not included in the display (.dsf, .dso, or .dss) file. This information, along with the names of the display files, is included in the SEASAVE configuration (.cfg) file. To save the entire setup, you must save the .cfg file.

Fixed Display or Scrolled Display

Setup for the Fixed and the Scrolled Displays are similar.

The Fixed Display Setup dialog box looks like this:

Click on Modify Display Parameters to get the Fixed Display Variables Setup dialog box:

Select the desired variable for each row by clicking Select Variable. A dialog box with a list of variables appears; make your selection and click OK.

Enter the number of desired digits after the decimal point for each variable’s data. When done, click OK.

Overlay Plot Display

The Display Setup dialog box looks like this:

The dialog box selections and buttons include:

•	Plot Label: Label placed at top, center of plot.

•	Show Fire Sequence, Show Bottle Lines, and Bottle Line Configuration: For a system integrated with a water sampler.
If Show Fire Sequence selected, SEASAVE lists the bottle closure order to the right of the plot.
If Show Bottle Lines selected, SEASAVE places a horizontal line in the plot to indicate the data associated with a bottle closure. Bottle Line Configuration defines the line -- line color and style, and line label

•	Auto Paging of the Display: If selected, the display pages down if the y-axis data exceeds the selected y-axis maximum for the plot. For example, if you set up the y-axis for 0 to 1000 dbars, and the actual cast exceeds 1000 dbars, the y-axis minimum/maximum will adjust to 1000 to 2000 dbars so that it can continue to display data.

•	Display Downcast Only: If selected, SEASAVE only plots data with pressure greater than the previous maximum pressure. It cannot differentiate between temporary upward movement due to ship movement and when the upcast actually begins, so data points where the CTD is moving upward due to ship heave will not display.

•	Show Mark Lines: If selected, SEASAVE places a horizontal line in the plot to indicate the data associated with the user marking a scan. Scan marking is done in the View menu; see Mark Scan Control.

Click on Modify Display Parameters to get the Overlay Display Parameters Setup dialog box:

The dialog box entries include:

•	Grid and Colors: Select a background color for the plot, and select whether to show a grid, along with the grid style and color.

•	Variable selections and plotting parameters: SEASAVE can plot one parameter on the y-axis and up to four parameters on the x-axis. For each parameter, select the desired variable by clicking Select Variable. A dialog box with a list of variables appears; make your selection and click OK. Then enter the label for the axis, number of major and minor divisions on the axis, line style and color, minimum and maximum value for the axis, and number of digits after the decimal point for the minimum/maximum value labels. Note that any data that falls below the minimum will plot at the minimum value; data that falls above the maximum will plot at the maximum value.

When done, click OK.

SEASAVE can be used to display and plot archived data as well as real-time data.

NOTE

To display archived data without a mouse:

•	Windows 2000 /XP – Press the Alt key to show the keyboard shortcuts (underlines) on menus. Press the appropriate letter (for example, A for ArchivedData menu) and use the arrow and Enter keys to navigate.

•	Windows 95 / 98 / NT – Keyboard shortcuts (underlines) appear on menus at all times. Press the Alt key and appropriate letter and use the arrow and Enter keys to navigate.

To Start Archived Data Display

1	In the ArchivedData menu, select Start. The Start Archived Data Display dialog box appears:

The dialog box selections include:

•	Select Data File: Click to select an archived data file. The Select Data File dialog box appears. Browse to the desired file and click OK.

•	Select .con File: Click to select the instrument configuration (.con) file. The Select Instrument Configuration File appears. Browse to the desired file and click OK.

•	Exam / Change .con File: Click to view or modify the instrument configuration and calibration coefficients. See Instrument Configuration.

•	Number of Scans to Skip Over: Allows you to skip any number of scans at the beginning of the data, allowing you to skip data from before the cast actually began (i.e., when the instrument was on deck and initially soaking in the water).

•	Number of Seconds to Skip between Computations: Allows you to skip data, speeding up the display. To calculate parameters for all data, set to 0. Note that this interacts with the Update Rate set for each display window, as illustrated by the examples below:
Example 1:
Number of Seconds to Skip between Computations = 5 seconds
Display Update Rate = 10 seconds
SEASAVE will calculate parameters every 5 seconds, but will update the display only every 10 seconds.
Example 2:
Number of Seconds to Skip between Computations = 10 seconds
Display Update Rate = 5 seconds
SEASAVE will calculate parameters every 10 seconds, and will update the display only every 10 seconds.

•	Start Display: Begin processing and displaying data.

•	Save and Exit: Save the archived data display setup (data and .con file names, number of scans to skip over, and number of seconds to skip between computations). If saved, the next time you select Start in the ArchivedData menu, the dialog box will appear with your saved selections.

Note that just above the Start Acquire button, the dialog box indicates if output ASCII data (to a COM port, not to a shared file) and/or sending data to a Remote Display (through a COM port) was enabled in the Configure menu. These features are available for archived data as well as for real-time data.

To Pause and Restart Archived Data Display

Fire Bottle

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 (.bl) file each time a bottle fire confirmation is received from the water sampler. The beginning and ending scan numbers correspond to approximately a 1.5-second duration for each bottle. For a 911plus system, SEASAVE also automatically sets the bottle confirm bit in the data (.dat) file for all scans within a 1.5-second duration after a bottle firing confirmation is received from the water sampler.

To Fire Bottles

1	Configure the Water Sampler.

2	Start Real-Time Data Acquisition.

3	When desired:
In the RealTime Data menu, select Fire Bottle, OR
Press Ctrl F3.
If you selected User Input in Water Sampler Configuration (Step 1), SEASAVE prompts you to enter the bottle number.

NOTES

•	The .bl file has the same file name and is placed in the same directory as the data file. For example, if the data file is test1.hex, the .bl file is test1.bl.

•	For an alternative method of firing bottles, see Fire Bottle Control.


Mark Scan

Mark Scan allows you to copy the most recent scan of data to a mark (.mrk) file as desired. The .mrk file can be used to manually note water sampler bottle firings, compare CTD data with data from a Thermosalinograph taken at the same time, or to mark significant events in the cast (winch problems, large waves causing ship heave, etc.) for later review and analysis of the data.

If a plot display is setup to Show Mark Lines, SEASAVE also draws a horizontal line in the plot each time you mark a scan.

To Mark a Scan
