The dataset also includes the sample collection date, cruise information, location, and depth of water. Finnigan DELTAplus XP by Thermo Fisher Scientific was used to determine the stable isotopes of carbon and nitrogen. The purpose was to characterize the sediment of the region at this time, some 30-40 years following the Ixtoc oil spill; to examine sediments for the preservation of a Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA) event and to determine a baseline isoscape for the Gulf of Mexico.
