Data Repository• Store metadata / data for cores
stored at other institutions• Rapid assessment of previous work
done in a geographical region, or on a proxy
• Sample access• Simplify transition to permanent
storage

DatabaseFileMaker Pro• Stores metadata for expeditions,
holes, cores, sections, samples; analytical data
• Mathematically corrects depth scale for gaps and gas expansion
• Provides multiple uniform corrected depth scales for all samples/analyses
DIS / ICDP…working on a new system:
consistent; fast; online
