Abstract:

This data set consists of data from the OC26 sediment trap moored at 28.7092 N and 88.4223 W from August 25, 2010 to August 30, 2012. Included in this record is the start date of the three week deployment, the DELTA 14C, delta 34S delta 13C and the delta 15N of the organic material collected in the trap.

Purpose:

The purpose of collecting this data was to describe the isotopic composition of the settling particulate organic matter following the oil spill. This information was useful for determining how long the Gulf water column was affected by petrocarbon.

Data Parameters and Units:

Cup# (sediment trap cup number); Start date (date that trap cup began three week deployment, mm/dd/yy); ∆14C-POC (delta 14C of particulate organic carbon, 0/00); δ34S-POM (delta 34S of particulate organic matter, 0/00); δ13C-POC(delta 13C of particulate organic carbon, 0/00); δ15N-PON (delta 14C of particulate organic nitrogen, 0/00)

Instruments:

Delta XP Thermo Finnegan isotope ratio mass spectrometer

Error Analysis:

Analytical reproducibility was on the order of 3 ‰ for 14C and 0.3 ‰ for 15N, 13C and 34S.
