NASA's Ocean Biology Distributed Active Archive Center (OB.DAAC) at NASA's Goddard Space Flight Center provides the global research community almost 4 Petabytes (PB) of satellite remote sensing data from a large number of operational, legacy, and international missions. This archive spans nearly 40 years of satellite measurements of ocean color, sea surface temperature, and sea surface salinity. OB.DAAC also maintains a publicly shared archive called "SeaBASS" of in-situ oceanographic and atmospheric data collected from ship-borne marine surveys, scientific buoys, and autonomous robotic "gliders". These data can be manipulated with the freely available "SeaDAS" software package which enables the processing, display, and analysis of ocean color and other applicable satellite remote sensing Earth science data.
