Abstract:

These data report the isotopic composition (13C and 14C) of sedimentary organic carbon within suspended particulate organic carbon in the southern Gulf of Mexico, collected in the summer of 2015.

Purpose:

This information reveals the characterization of sedimentary organic carbon collected from the sea floor of the Gulf of Mexico. Our objective was to characterize the sediment of the region at this time, some 30-40 years following the Ixtoc oil spill.

Data Parameters and Units:

Sample ID, Sample equipment (multicore, shipex), Cruise ID, Collection date (MM/DD/YYYY), Latitude (decimal degrees), Longitude (decimal degrees), depth (meters), d13C a measure of stable isotope composition, the 13C to 12C ratio, D14C a measure of the content of 14C in the organic matter, 15N Average, %C Average, d14C. All averages are from 2 replicates.
