Results of Whole-Rock Organic Geochemical Analyses of the CRP-3 Drillcore, Victoria Land Basin, Antarctica
Sediments and rocks recovered in CRP-3 coring operations contain minute amounts of organic matter (average 0.3% TOC). TOC contents and C:N ratios are zoned systematically: those rocks encountered at depths greater than 330 meters below sea floor (mbsf) contain less organic matter and have higher TOC...
