1. SIOExplorer: Digital Library Projects R/V Alexander Agassiz November, 1907 UCSD Libraries Scripps Institution of Oceanography San Diego Supercomputer Center Stephen Miller spmiller@ucsd.edu http://SIOExplorer.ucsd.edu

2. Two new projects at UCSD Bridging the Gap between Libraries and Data Archives NSF NSDL Collections Track SIOExplorer: Web Exploration of Seagoing Archives NSF ITR

3. Encourage inquiry Provide access to Voyages of Discovery SIO Naga Expedition 1959-61 Artists on board Consider opportunities “What’s this?” links from image Data (“What”) Instruments (“How”) Other voyages

4. Naga Expedition departed SIO June 15, 1959 Crossed Pacific

5. Voyages of Discovery in the Pacific 1950’s Crossing the date line

6. Typical archive problems Substantial material already exists Data archives Historical archives But it is hard to get Locals only Not all online Expertise needed Custom search, retrieval software Data archives lack library standards Search Metadata

7. Drift Expedtion departed SIO June 14, 2001 Crossing Pacific Galapagos in August “Dive and Discover” Live on the web  Link to WHOI, and other sites 

8. R/V Albatross departed SIO 1904 Search SIO Archives Scanned image 1904-1905 Expedition Report Sigsbee sounding machine

9. EM120 Multibeam Sonar No. receive beams:191 Depth range:20 to 11000m Max swath width:6 x water depth Transmit beamwidth:1-2 degrees Receive beamwidth:1-2-4 degrees Sonar backscatter imagery:Included System precision:0.1% of depth RMS R/V Roger Revelle 20 km wide swath First sea trial January 2001

10. SIO SeaBeam Expeditions, 1981- 440 GB digital holdings Adding 100 GB/year 233 swath mapping cruises on vessels - Thomas Washington Melville Revelle

11. Geological Data Center (GDC) Approx. 3000 cruise legs online Bathymetry, magnetics, gravity

12. Open research data for student discovery Create custom maps on demand Select lat, lon Select global database: Global topography Sediment thickness Crustal age Overlay earthquakes, volcanoes, etc Multibeam maps on demand? MB-System running on SDSC computers Crustal Age Sediment thickness Global Topography

13. Sampling Build on EarthRef.org capabilities Seamount catalog –Embed multibeam into Global Topography Analysis tools Sample index, 1968- 100,000 entries 500 types (all disciplines)

14. Marine database problems in 6 areas Where might Alexandria Digital Library play a role? 1.Search 2.Access 3.Quality 4.Display and analysis tools 5.Flexibility 6.Long-term stability

15. Problem 1 -- Search Find what you’re looking for Data Images Documents Discover things you didn’t know about Like browsing in library stacks Distributed archives Not just your own institution

16. Modern database search engine Geospatial Lat, lon Temporal “1995-2000” Keyword Region“East Pacific Rise” Vessel“Melville” Cruise“COOK01MV” Expert-level Research, teacher, student, public

17. Make it easy to maintain Automatic tools to harvest metadata from data files Use templates when needed Use controlled vocabularies DLESE, AGU, or other Sub-disciplines –Marine geology, geochemistry, petrology Data and sample types –Bathymetry, dredged rock Interface with NSDL Core Integration

18. Use ADL gazetteer Expand with marine place names, as needed Embed domain-specific metadata into standard catalog Are ADL buckets adequate? Lat-lon bounds Date Data type Quality Multibeam-specific attributes –SVP corrected –Roll bias –Status of manual editing

19. SIO 100 th Anniversary September 26, 2003 SIO, 1909 SIO, 1926 http://SIOExplorer.ucsd.edu
