The SeaWiFS Bio-optical Archive and Storage System (SeaBASS) is a data archive of in situ oceanographic data used to support satellite remote sensing research of ocean color. SeaBASS is used for developing algorithms for satellite-derived variables (such as chlorophyll-a concentration) and for validating or “ground-truthing” satellite-derived data products. {{cite journal | last1=Werdell | first1=P.

Oceanography projects funded by the NASA Earth Science program are required to upload data collected on research campaigns to the SeaBASS data repository to increase the volume of open-access data available to the public. {{cite web | title=Data & Information Policy | website=Science Mission Directorate | date=8 February 1996 | url=https://science.nasa.gov/earth-science/earth-science-data/data-information-policy | access-date=11 October 2021}} {{cite journal |last1=NASA ROSES |title=Ocean Biology and Biogeochemistry.

| Light absorption spectra of phytoplankton show the amount of light in different colors of the visible light spectrum absorbed by ocean phytoplankton. Spectral light absorption is one type of data stored in the SeaBASS data repository.

| Researchers prepare instruments to deploy from a research vessel (in situ). Data collected using instruments like these ones get uploaded to SeaBASS to help scientists derive products (like chlorophyll-a concentration) from satellite data.
