Mississippi Fan Fold Belt Study (1985)
The earliest piston coring surveys conducted in the deep-water Gulf of Mexico did not always site cores based on geophysical evidence of hydrocarbon seeps. The Mississippi Fan Fold Belt Study collected 229 cores primarily in the northern Atwater Valley protraction area. A single core was collected in the center of selected blocks in a general grid pattern. As a result, few cores showed significant liquid hydrocarbon anomalies. Several hydrocarbon seeps have been subsequently discovered in this region, although the numbers of seeps are less than in other areas of the deep-water Gulf, presumably as a result of sediment slumping around the Mississippi Fan Channel.
Deliverables for this study include PDF images of core logs (core locations and descriptions) and data volumes with the results of the following analyses: total scanning fluorescence, C15+ gas chromatography, C1-C4 hydrocarbons (headspace), and biomarker.
