Dataset for: Partial Photochemical Oxidation Was a Dominant Fate of Deepwater Horizon Surface Oil

This dataset includes collection date and locations for surface oil collected in 2010 and deposited oil collected in 2010 and 2016. Data for 34 surface oil samples and 46 deposited oil residues collected in 2010 includes bulk oxygen content, oxidized hydrocarbon content, carbonyl IR-stretching, and octadecane to phytane ratio. Data from 39 deposited oil samples collected in 2016 contains oxidized hydrocarbon content. Peak ratios for bioindicators are provided for 6 surface samples and 5 deposited residues collected in 2010, 1 deposited residue collected in 2012, and 3 deposited residues collected in 2016. Experimental data provided reports the oxygen and dissolved inorganic concentration data from oil weathered in the field and in the lab, in the presence and absences of salt, and with and without a catalase.
