The OBPG serves as a Distributed Active Archive Center (DAAC) for satellite Ocean Biology (OB) data produced or collected under NASA's Earth Observing System Data and Information System (EOSDIS), including those from historical missions and partner space organizations and is a member of the International Council for Science - World Data System (ICSU-WDS). This website thus serves as the primary data access portal to the NASA OB.DAAC. The links below provide a variety of methods to access the holdings of the OB.DAAC, including visual browsers that enable point-and-click access by data levels and direct access for bulk download. In agreement with partner organizations, some data access requires user registration to enable better tracking of usage metrics.

Data Management

The data management plan describes the acquisition, generation, management, archive and distribution of science data products generated by the Ocean Data Processing System (ODPS). For a detailed description of science data products, data flows, supported sensors, and data availability, archiving and distribution, please refer to the plan document.

Data Access

Please be advised: Our data are undergoing a filenaming convention update. This process will occur over time, upon ocean color and sea surface temperature reprocessing for each mission.

Level 1 & 2 Browser - visual browse, download and data order access to all supported satellite data for Level-1 and Level-2 scenes at observed geographic scale and temporal granularity including cross satellite and in situ data search capabilities.

Level 3 Browser - visual access to global composites at various spatial and temporal scales.

Direct Data Access - direct access to all available data through https protocol, suitable for bulk download. Examples of how to download data from the command line can be found on our data download methods page.

Data File Search - direct access via filename search, including support for wildcard search on partial filenames.

SeaBASS Field Data - community archive of field data relevant to ocean color research, algorithm development, and validation.

Other Resources - links to partners that also distribute OB.DAAC products or other products derived from OB.DAAC holdings.
