Our business hours are Monday through Friday, 0800 to 1700 Pacific Standard Time (1600 to 0100 Universal Time) in winter and 0800 to 1700 Pacific Daylight Time (1500 to 0000 Universal Time) the rest of the year.
Summary
Seasoft V2 consists of modular, menu-driven routines for acquisition, display, processing, and archiving of oceanographic data acquired with Sea-Bird equipment. Seasoft V2 is designed to work with a PC running Win XP Service Pack 2 or later, Windows Vista, or Windows 7.
Seasoft V2 is actually several stand-alone programs:
• SeatermV2 (a launcher for Seaterm232, Seaterm485, SeatermIM, and SeatermUSB), Seaterm, and SeatermAF terminal programs that send commands for status, setup, data retrieval, and diagnostics to a wide variety of Sea-Bird instruments.
Note: SeatermV2 is used with our newest generation of instruments, which have the ability to output data in XML.
• Seasave V7 program that acquires and displays real-time and raw archived data for a variety of Sea-Bird instruments.
• SBE Data Processing program that converts, edits, processes, and plots data for a variety of Sea-Bird instruments.
• Plot39 program for plotting SBE 39, 39-IM, 39plus, and 48 data.
This manual covers only SBE Data Processing.
Note:
The following Seasoft-DOS
calibration modules are not available in Seasoft V2:
• OXFIT – compute oxygen calibration coefficients
• OXFITW – compute oxygen calibration coefficients using Winkler titration values
• PHFIT – compute pH coefficients See the Seasoft-DOS manual.
System Requirements
Seasoft V2 was designed to work with a PC running Win XP Service pack 2 or later, Windows Vista, or Windows 7.

Notes:
• SBE 37-SI and 37-SIP - SBE Data Processing can be used with data uploaded from firmware version 3.0 and later. Earlier versions of these MicroCATs did not have internal memory, and SBE Data
Processing is not compatible with real-time MicroCAT data.
• SBE 39, 39-IM, 39plus, and 48 data - SBE Data Processing support is limited; see Processing SBE 39, 39-IM, and 48 Data and Processing SBE 39plus Data in Section 3: Typical Data Processing Sequences.

Software Modules
SBE Data Processing includes the following modules:
Type Module Name Module Description
Instrument configuration
See Section 4. Configure Define instrument configuration and calibration coefficients.
Convert raw .hex or .dat data to engineering units, and store converted data in .cnv file (all data) and/or .ros file (water bottle data).
Bottle
Summary Summarize data from water sampler .ros file, storing results in .btl file.
Mark Scan Create .bsr bottle scan range file from .mrk data file.
Align CTD Align data (typically conductivity, temperature, oxygen) relative to pressure.
Bin Average Average data, basing bins on pressure, depth, scan number, or time range.
Buoyancy Compute Brunt Väisälä buoyancy and stability frequency.
Cell Thermal
Mass Perform conductivity thermal mass correction.
Derive Calculate salinity, density, sound velocity, oxygen, etc. based on EOS-80 (Practical Salinity) equations.
Derive TEOS-10
Calculate salinity, density, sound velocity, etc. based on TEOS-10 (Absolute Salinity) equations.
Filter Low-pass filter columns of data.
Loop Edit Mark scan with badflag if scan fails pressure reversal or minimum velocity test.
Wild Edit Mark data value with badflag to eliminate wild points.
Window Filter Filter data with triangle, cosine, boxcar, Gaussian, or median window.
File
manipulation See Section 7.
ASCII In Add header information to .asc file containing ASCII data.
ASCII Out
Output data and/or header from .cnv file to ASCII file (.asc for data, .hdr for header). Used to export converted data for processing by non-Sea-Bird software.
Section Extract data rows from .cnv file.
Split Split data in .cnv file into upcast and downcast files.
Strip Extract data columns from .cnv file.
Translate Convert data in .cnv file from ASCII to binary, or vice versa.
Data plotting variables, overlay plots, and TS contour plots). Plots can be printed, or saved to a file or clipboard. Can plot data at any point after Data Conversion has been run.
Miscellaneous Performed on data typed in by user.
See Section 9.
SeaCalc III Calculate derived variables from one user-input scan of temperature, pressure, etc.
