SEASOFT-DOS© consists of modular, menu-driven routines for acquisition, display, processing, and archiving of oceanographic data acquired with Sea-Bird equipment. A DOS program designed to run on an IBM-compatible computer (XT/AT/386/486/Pentium), SEASOFT-DOS usually performs correctly when run under Windows.
Sea-Bird recommends that all users upgrade to the Windows version of SEASOFT, unless there is a compelling reason to continue running DOS. The last update of SEASOFT-DOS was done in early 2001. Processing capability added to our software after that time has been added only to the Windows versions (for example, processing data from new Sea-Bird instruments -- such as SBE 16plus, 16plus-IM, 19plus, 45, 49, 50 -- or interfacing to additional auxiliary sensors). While Sea-Bird continues to support customers using the DOS software by answering questions, we will not change, improve, or correct the DOS software.
SEASOFT-DOS supports the following Sea-Bird products:
SBE 9 CTD with SBE 17 SEARAM
SBE 16 SEACAT C-T Recorder (older product, not SBE 16plus)
SBE 19 SEACAT Profiler (older product, not SBE 19plus)
To enhance data integrity, raw data is acquired from the instruments and stored as raw, unmodified data. A conversion program (DATCNV) uses the instrument configuration and calibration coefficients to create a converted engineering unit data file that is operated on by all SEASOFT-DOS post-processing modules. Each SEASOFT-DOS module that modified the converted data file adds information to the header of the converted file, permitting tracking of how the various oceanographic parameters were obtained.

| SEACON | Define instrument configuration and calibration coefficients. | |
| SEASAVE | Acquire real-time data and display raw archived data. | |
| Data Editing | ASCIIIN | Add header information to a file containing rows and columns of ASCII data. |
| MARKSCAN | Create bottle scan range (.bsr) file from .mrk data file. | |
| SECTION | Extract rows of data from file. | |
| SPLIT | Split data into upcast and downcast files. | |
| STRIP | Extract columns of data from file. | |
| TRANS | Convert data format from ASCII to binary, or vice versa. | |
|
Data Processing on converted data from .cnv file |
ALIGNCTD | Align C, T, P, and oxygen. |
| BUOYANCY | Compute buoyancy (Brunt-Väisälä) and stability frequency. | |
| BINAVG | Average data, based on pressure, depth, scan number, or time ranges. | |
| CELLTM | Perform conductivity thermal mass correction. | |
| DERIVE | Calculate derived variables (salinity, density, sound velocity, oxygen, potential temperature, dynamic height, etc.) from data. | |
| FILTER | Low pass filter columns of data. | |
