1. Mind the Gap: Finding Data Across Decades and Disciplines with the SSDB Stephen P. Miller 1, P. Dru Clark 1, Jacob M. Perez 1, Aaron D. Sweeney 1, John Helly 1,2, Karen I. Stocks 2, and Donald W. Sutton 2 1 Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA, USA 2 San Diego Supercomputer Center, University of California, San Diego, La Jolla, CA, USA The IODP Site Survey Data Bank (SSDB; http://ssdb.iodp.org) primarily supports Site Survey Panels as they evaluate proposals for drilling. Launched in 2005, it holds over 7000 digital objects, such as seismic sections, bottom photographs, bathymetric maps and background reports; and can securely hold proprietary data.http://ssdb.iodp.org SSDB provides a reliable long-term archive from the conception of proposal ideas, through site evaluation, operations, publication, and education. Built on a foundation of quality control, geo-referencing, and controlled vocabularies, its flexible and extensible infrastructure can support a wide range of data types and disciplines, allowing it to evolve with IODP science priorities and practices. Current expansions include mapping metadata for harvest in the Scientific Earth Drilling Information Service (SEDIS) format and creating ”SSDB-in-a-Box” laptops that can transport the entire collection to a vessel or remote office. The SSDB benefits from technology shared with the SIOExplorer Digital Library of Scripps expeditions, and the new “Rolling Deck to Repository” effort to archive all routine underway shipboard data from US research vessels (http://www.rvdata.us).ww.rvdata.us Hosted at SDSC machine room for high bandwidth 24/7 operations. System replicated at SIO and deep archived at 3 remote sites across the U.S. The SSDB also archives 33,381 legacy physical objects, including maps, reports, seismic sections, disks, and tapes. Review Panels: Decision support system provides access to site-specific data for each proposal. INTViewer enables interactive display of seismic data across the web. Seismic INTViewer Mobile Support: SSDB-In-a-Box is a laptop for remote use at meetings or on vessels, independent of Internet connection. Complete Site Characterization: Proponents upload the data they need to support a proposal. Objects on proprietary hold are protected by username/password security. Researchers: Furthering science through data discovery and download. Search by Proposal, Expedition, Leg, data type, format, lat/lon, date, etc. Persistence: Preserving data for the long term as a digital library with metadata, so they can always be discovered. The Site Survey Data Bank Quality Control: Every upload must meet IODP data and metadata requirements, including use of certified site names. The SSDB Team: The SSDB is developed by a team from the Scripps Institution of Oceanography and the San Diego Supercomputer Center, at the University of California, San Diego, under a contract with IODP-MI, funded by the NSF. Supporting IODP Science Operations and Expeditions: Packaging the data needed to make on-site operational decisions. Select from a community-accepted list of standard categories. Seafloor features from sidescan data Location map to relate activities, sites, and data sets Subsurface profile from interpreted seismic section Integrating into SEDIS: Entire SSDB Collection can be searched by SEDIS.
