Scientific Stewardship
• Acquire: receive ocean data from U.S. and foreign sources
• Archive: preserve those data assets for the long term
• Access: provide access to archived data for business, federal, science, and many other users
• Add Value: assemble easy-to-use, long term collections for science and applications

Metadata
• Brief Access Recordo Stewardship: NODC Data Content Managers control the
content o Accession Tracking Database is master repository of
Access metadata• FGDC Metadata
o Archive Holdings WAF, raw granule-level recordso Automated process merges Brief Access Records with raw
FGDC XML records to generate live archive WAF

• NODC Collections WAFo Filtered WAF for NODC Geoportal Server and
NESDIS Data Centerso Collection-level records are substituted for their
component granule-level recordso Links to data access mechanisms are generatedo Also represented in HTML for harvesting by

• Data.gov/Geospatial One-Stop WAFo Starts with NODC Collections WAFo Only collections/granules containing data
available for immediate download are includedo Offline, restricted access and documentation-
only accessions are filtered out
