Central Slope Seep Study

The Central Slope Seep Study (1996-1997) sought to identify seafloor seeps across the mid- to lower slope in the Atwater Valley and Walker Ridge protraction areas where both Jurassic and Cretaceous source rocks are thought to be generative. State-of-the-art geophysical techniques were used to site 161 cores in areas that had not been extensively cored in previous studies. The data were used to test the hypothesis that Tithonian source rocks have given rise to oil north of the escarpment, whereas Oxfordian source rocks have given rise to oils in front of the salt sheet.

Deliverables for this study include PDF images of core logs (core locations and descriptions), data volumes with the results of the following analyses: total scanning fluorescence, C15+ gas chromatography, C1-C4 hydrocarbons (headspace), and biomarker, and a final, interpretive report.
