Discovery is enabled through numerous interfaces designed for both humans and their machine clients.
Human-to-machine interfaces include government-mandated generalized portals like Data.gov and Geospatial One-Stop (GOS)
Discovery services are available for ALL of the NODC Archive holdings, but better metadata supports better discovery!

Enhanced online access, visualization, and analysis tools: These capabilities require more structured metadata and standardized file formats, so are available to the fewest archive holdings.
Data Access Protocol (DAP): Requires standard file formats so is available to fewer archive holdings.
Basic FTP/HTTP access for all Archival Information Packages (AIP) in the NODC Ocean Archive: These distribution methods have no format or metadata requirements so they work for all archive holdings, but they provide only basic download capability.
