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.

本数据集收录了2010年采集的表层溢油，以及2010年与2016年采集的沉积溢油的采集日期与采样点位信息。2010年采集的34份表层溢油样品与46份沉积溢油残渣样品的检测数据包括：总氧含量、氧化烃类含量、羰基红外伸缩振动（IR-stretching）参数，以及正十八烷与植烷（phytane）的比值。2016年采集的39份沉积溢油样品仅包含氧化烃类含量数据。针对2010年的6份表层样品、5份沉积溢油残渣，2012年的1份沉积溢油残渣，以及2016年的3份沉积溢油残渣，本数据集提供了生物标志物峰比值数据。本数据集还包含野外与实验室环境下，分别在有盐、无盐条件，以及添加过氧化氢酶（catalase）与未添加过氧化氢酶的条件下，风化溢油的氧含量与溶解无机浓度（dissolved inorganic concentration）实验数据。本数据集为以下发表成果提供数据支撑：Ward, C.P.、Sharpless, C.M.、Valentine, D.L.、French-McCay, D.P.、Aeppli, C.、White, H.K.、Rodgers, R.P.、Gosselin, K.M.、Nelson, R.K. 与 Reddy, C.M. 于2018年发表于《环境科学与技术（Environmental Science & Technology）》的论文《局部光氧化是深水地平线表层溢油的主要归趋》，DOI: 10.1021/acs.est.7b05948
