The Geological Data Center:
Our main focus is to curate and provide access to oceanographic data, especially from Scripps expeditions, making them accessible for scientific and educational use worldwide.
The GDC currently has three main projects: the Science Support Office of the International Ocean Discovery Program, Rolling Deck to Repository, and SeaView. The GDC also maintains the SIOExplorer portal.
The Science Support Office of the International Ocean Discovery Program (SSO IODP)
The GDC supports the information technology systems used by the IODP Science Support Office as it manages the submission and review of IODP scientific ocean drilling proposals. This includes the Site Survey Data Bank (SSDB) a repository for digital site survey data submitted in support of 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.
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 has developed 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 Centers for Environmental Information. Data submission is 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).
SeaView is an NSF-funded EarthCube Integrative Activity Project. It is working with existing data repositories to make oceanographic data more Findable, Accessible, and Interoperable. The premise is simple and has two components. First, reformatting data for scientist’s tool of choice can be a barrier and a time sink. Existing ocean data repositories provide data in different format options, such that bringing data together from multiple repositories into a single analysis or visualization environment requires reformatting. Second, finding data of interest across multiple repositories can be challenging or time consuming, particularly when the data of interest is not easily defined by the search facets commonly supported by data portals. Searches on location or parameter may be easy, but those on cruise name or program/initiative may not be. SeaView is working with five oceanographic data repositories on a lightweight approach to publish content in common data formats, focusing on thematic collections.

Data, documents and images from expeditions by the Scripps Institution of Oceanography (SIO) since 1903 are web-accessible through the SIOExplorer. 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.
