Scripps Institution of Oceanography Geological Data Center

The GDC manages a database of navigation, magnetics, gravity, single-beam bathymetry and multibeam bathymetry and other data collected on SIO vessels and maintains large holdings of data from other institutions. The Geological Data Center (GDC) at SIO has been continually adding to its digital and analog archives since its formation in 1970. The holdings now include 295 SIO expeditions, and more than 646 cruises legs, covering 2.5 million nautical miles, and contain about 440 GB of digital data.
