Abstract:

Dataset contains selected biomarker ratios in sediment cores from 5 sampling sites in the Gulf of Mexico obtained using gas chromatography–mass spectrometry (GC-MS).

Purpose:

Ratios of selected biomarkers were calculated in order to compare them to the GC-MS fingerprint of Macondo Well oil.

Below are the coordinates for each sampling sites: dsh10: 28.97905, -87.891617 dsh08: 29.122783, -87.867733 dwh01: 28.724367, -88.387283 sl1040: 29.19605, -88.868833 sw01: 28.239717, -89.120667 The values in Row 1, Columns B through S, represent the station and date for each core sample. The format of the values in this row is "Station Name/Month/Year/Day" (for example, the value "SW01_Aug12_5" would be used to indicate that the results reported in this column came from analyses of a core sample collected at station SW01 on August 5th, 2012). The biomaker ratios (which are reported in the file titled "biomaker_ratios.csv") were calculated from the concentrations of each biomaker (which are measured in ug/g and are reported in the file titled "biomaker_conc.csv").
