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
State-of-the-art has advanced since the 2001 workshop
SIOExplorer: online access to SIO data 753 cruises 102,000 digital objects 5 federated collections Cruises Photo archives Seamounts Educator’s Geological samples
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 *** HCGF B Go FLow rinse UCSC N W g COOK01MV HCGF E Go FLow rinse UCSC N W 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

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 Live demo by Dru Clark
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
