Abstract:

This data set investigates the distribution of aliphatics and petroleum biomarkers in surface and subsurface sediments collected in the Gulf of Mexico using Gas Chromatography-Mass Spectrometry (GC-MS). Additional data include organic carbon contents and carbon isotopic signatures. Samples were collected in May, September and November 2010, July 2011, July 2012 and July 2013.
