1. SIOExplorer Stephen Miller Scripps Institution of Oceanography USA International Data Exchange Workshop Building a Global Data Network for Studies of Earth Processes at the World's Plate Boundaries Kiel, Germany May 9, 2007

2. State-of-the-art has advanced since the 2001 workshop

3. SIOExplorer: online access to SIO data 753 cruises 102,000 digital objects http://SIOExplorer.ucsd.edu 5 federated collections Cruises Photo archives Seamounts Educator’s Geological samples

4. Preserving the complete context of an expedition Authoritative version of all cruise observations Support multiple disciplines Quality controlled data and metadata “One stop shopping” All SIO cruises since 1950 #*** Hydrocast - GoFlow *** 0446 260800 0 HCGF B Go FLow rinse UCSC 17-13.79N 107-44.33W g COOK01MV 0604 260800 0 HCGF E Go FLow rinse UCSC 17-14.53N 107-43.53W g COOK01MV What’s available Reports Cruise, QC with profiles, logbooks Navigation Underway gravity, magnetics (mgd77) Multibeam swath data Also grids, plots, visualization files Subbottom profiler Current profiler ADCP, HDSS Meteorology XBT, CTD, SVP Samples

5. SIOExplorer extended to WHOI Joint NSF/Library of Congress funding DIGARCH digital archiving and preservation Integrate SIO, SDSC, WHOI tools and data 30 years of WHOI cruises 4258 Alvin dives Jason ROV surveys Add SIO Deep Tow Interoperable digital libraries SIO WHOI Oregon State

6. SSDB http://ssdb.iodp.org Support review of ocean drilling proposals Long-term access for research and education Site Survey Data Bank North Atlantic Climate P572, E303/306

7. Auto-harvesting for an imperfect world Authoritative sources of information often are wrong Incorrect, missing, misspelled, misplaced, abbreviation, synonym Solution: database-enabled harvesting SIO staging database for 1079 cruises http://gdccoll.ucsd.edu/ Live demo by Dru Clark

8. Database-enabled harvesting Detect problems across entire collection Scan variations of a metadata value Repair problems before final archiving Added benefit: Improve your controlled vocabularies Example: show all distinct values of “mag sensor” in entire collection Error - not a magnetometer Auto detection of swath file problems

9. Controlled vocabulary dictionary Include description of each authorized value Explain discipline-specific jargon and acronyms Reduce the number of emails from colleagues, wondering what you meant,” ”,” ” SIOGDC_Instrumentation_Model,"SBclassic multibeam","original SeaBeam 16 beam system on Thomas Washington 1981-1992" SIOGDC_Instrumentation_Model,"SB2000 multibeam","second generation SeaBeam 121 beam system on Melville 1992-2007" SIOGDC_Instrumentation_Model,"SB2112 multibeam","third generation SeaBeam 141 beam system on Revelle 1996-2000, also on Knorr 1994-" SIOGDC_Instrumentation_Model,"EM120 multibeam","Kongsberg Simrad 191 beam system on Revelle 2001-" SIOGDC_Instrumentation_Model,"EM3000 multibeam","Kongsberg Simrad 300 KHz system temporarily installed on pole” SIOGDC_Instrumentation_Model,"Geometrics G-866 magnetometer","towed proton magnetometer SIO 1996-2003" SIOGDC_Instrumentation_Model,"Geometrics G-801-3 magnetometer","towed proton magnetometer SIO 1984-1997" SIOGDC_Instrumentation_Model,"Varian 4970 magnetometer","towed proton magnetometer SIO 1967-1983" SIOGDC_Instrumentation_Model,"SeaSPY marine magnetic gradiometer","towed gradiometer SIO 2003-” SIOGDC_Instrumentation_Model,"Askania GSS2 gravimeter","SIO shipboard gravimeter 1973-1986" SIOGDC_Instrumentation_Model,"BGM-3 gravimeter","SIO shipboard gravimeter 1983-" SIOGDC_Instrumentation_Model,"BGM-6 gravimeter","SIO shipboard gravimeter 1997-2002" SIOGDC_Instrumentation_Model,"LaCoste-Romberg S-38 gravimeter","SIO shipboard gravimeter 2002-2005" SIOGDC_Submergence_NavigationType,"LongBaseLine","vehicle navigation from acoustic transponders on sea floor" SIOGDC_Submergence_NavigationType,"DP","vehicle navigation with dynamic positioning" SIOGDC_Submergence_NavigationType,"DVLNav","vehicle navigation from Doppler velocity system" SIOGDC_Submergence_NavigationType,"USBL","vehicle navigation from ultra short baseline system on hull of vessel" SIOGDC_Submergence_NavigationType,"Dead reckon","vehicle navigation from dead reckoning" SIOGDC_Submergence_NavigationType,"Cable trajectory model","vehicle navigation from a cable trajectory modeling program" A step toward interoperability among institutions
