The US Geological Survey Energy Resources Team's Organic Geochemistry Laboratory has made available its Alaska Organic Geochemistry Data Base. The data represent efforts to investigate "the origin and occurrence of organic fossil fuels." Available in multiple file formats, tables may be accessed individually, or the entire database may be downloaded (24 MB). A few table titles include Stable Carbon Isotopes of Whole Oils, Standard Chemical Analyses of Gas, and Specific Gravity of Oils.
