The Geological Data Center:

Our main focus is to archive marine geological data, especially from Scripps expeditions, making them accessible for scientific and educational use worldwide. The GDC currently has three main projects: SIOExplorer, Rolling Deck to Repository, and the Site Survey Data Bank.


Data, documents and images from expeditions by the Scripps Institution of Oceanography (SIO) since 1903 are web-accessible through the SIOExplorer project as part of the NSF-funded National Science Digital Library (NSDL).  The effort is a collaboration among researchers at Scripps and the San Diego Supercomputer Center (SDSC), and archivists and librarians from the UCSD Library. Shipboard data published on the SIO Explorer site include:

  • Underway geophysical data, including time, position, bathymetry, sidescan, magnetics, gravity, seismics.
  • Standard supporting data, including sea state, XBT, CDT, sea surface temperature and salinity, and derived SVP, as well as calibration data for each sensor.
  • Station information for dredging, coring, trawling, and other over-the-side operations, with complete data or metadata, as appropriate.
  • Derived data such as grids or plots should be archived for high-demand products, or when non-trivial processing steps are required.

Rolling Deck to Repository (R2R)

With their global capability and diverse array of sensors, the U.S. academic research fleet is an essential mobile observing platform for ocean science. Data collected on every expedition are of high value, especially given the high costs and increasingly limited resources for ocean exploration. The Rolling Deck to Repository (R2R) program aims to develop comprehensive fleet-wide management of underway data to ensure preservation of and access to our national oceanographic research data resources. The R2R Portal is a central shore-side gateway through which underway data from oceanographic expeditions will be routinely cataloged and securely transmitted to the national long-term archives including the National Geophysical Data Center (NGDC) and National Oceanographic Data Center (NODC). Data submission will be established through vessel operators rather than individual science parties, ensuring routine preservation of the full underway data distribution. R2R is a collaboration between Lamont Doherty Earth Observatory, Woods Hole Oceanographic Institution, Florida State University, and the GDC.

The Site Survey Data Bank (SSDB)

The SSDB is a repository for digital site survey data submitted in support of Integrated Ocean Drilling Program (IODP) proposals, expeditions and related activities. Many files are freely available to support research and education. The SSDB also contains legacy site survey data for some older ODP proposals and legs. Analog site survey data (e.g. paper plots) submitted in support of ocean drilling proposals and expeditions/legs are stored on site at Scripps Institution of Oceanography. The SSDBquery and SSDBlegacy tools, available on the SSDB site, are the primary search interfaces for SSDB data (SSDBlegacy requires a free registration).
