SeaDAS is a comprehensive software package for the processing, display, analysis, and quality control of ocean color data. While the primary focus of SeaDAS is ocean color data, it is applicable to many satellite-based earth science data analyses. Originally developed to support the SeaWiFS mission, it now supports most U.S. and international ocean color missions.

The SeaDAS 8.x platform (an extension of the ESA SNAP platform) serves as an application platform to the NASA SeaDAS Toolbox and the ESA Sentinel-3 Toolbox. The core elements of NASA SeaDAS science processing (both command line and GUI-based) are contained within the SeaDAS ToolBox. The NASA satellite mission data file readers and the ESA processors for the Sentinel-3 missions are contained within the Sentinel-3 Toolbox. SeaDAS 8.x is a significant modification over SeaDAS 7.5.3 regarding the core components and inner framework of the GUI.

The latest version of SeaDAS is 8.3.0, which contains SeaDAS Toolbox (version 1.3.0) and Sentinel-3 Toolbox (version 9.0.3). There is also a SeaDAS version 8.3.9 (Mac OS only) which fixes the issue with using Mac OS 13 Ventura.
