Data wereinitially collected digitally in a relational datamanagement system known as S1032, andcore descriptions and some other prime datawere recorded on paper. Original raw fileswere archived for any future data verificationpurpose.Janus, an Oracle-based relational databasewith a Web interface, was developed between1994 and 1997. This database provided anintegrated view of the core sections, samples,and science data collected in all laboratorieson board the ship. Janus was first utilized duringLeg 171.ODP Core Data DetailsImages Archived on Server(s)Size (GB)Core-table photos (PDF) 13.47Core-section images (JPG) 27.85Close-up photos (JPG*) 7.11Microphotos (TIF) 0.26DITIMAGE (SID) 18.43Additional (TIF) 0.22Scanned paper prime data images (PDF) 10.83Total archived on server/Janus 78.18*closeup estimate after completion = 10.83 GBImages Archived on Disc/Photo/Paper Size (GB)Estimated amount from mediaScanned core-table photos (TIF) 1,400.00Section images (Legs 198–210) (TIF) 1,100.00Scanned close-up photos (Legs 134–210) (TIF) 602.50Stored offline on hard driveScanned paper prime data (TIF) 70.50Total 3,173.00“The Ocean Drilling Program curatedmore than 130 miles of core recoveredduring 20 years of operations.”The Janus Web interface was created to providestandard data queries for the public andscientists to view and download data from theODP database. The Janus database was continuallyimproved from 1997 through the endof ODP operations in 2003. Some enhancementsincluded modifications in calibrationprocedures, addition of new data types, andimprovements to overall database performance.A significant addition to Janus wasaccess to digital images of cores, core sections,and scans of prime paper data (e.g., handdrawnvisual core description notes).During the final decade of the Program, datafrom Legs 101–170 were migrated into Janus.The Janus database currently contains paleontological,lithostratigraphic, chemical, physical,sedimentological, and geophysical data frommore than 2 million ODP core samples (www.odplegacy.org/samples_data/data.html). Atthe end of the Program, all legacy data (Legs100–210) were transmitted to the National55
