Biological and chemical data of oil-derived elements being assimilated by oysters due to the Deepwater Horizon Oil Spill collected in Alabama and Mississippi coastal waters, June 2008, and April-July 2010(NODC Accession 0118498)

This dataset contains stable isotope ratios of carbon and nitrogen in oyster shell, suspended particulate matter (SPM), and oil from the Deepwater Horizon oil spill. Shell material was sampled from oysters grown at five sites along the Mississippi-Alabama coast and in Mobile Bay before, during, and after the spill (June 2008, April-July 2010). Samples of SPM were collected from the same or equivalent sites and timeframes. Oil samples came from tar balls, mats, and semisolid oil forms collected from sediments along the shoreline from the Florida-Alabama border to Petit Bois Island in Mississippi. For all samples, the stable isotope ratios of carbon and nitrogen were determined. Oyster shell samples were also analyzed for six trace and minor elements which have been highlighted for use in detection of hydrocarbon pollution (Cd, Co, Mo, Ni, Pd, V).

本数据集涵盖了深水地平线（Deepwater Horizon）漏油事件中采集的牡蛎壳、悬浮颗粒物（Suspended Particulate Matter, SPM）以及油污的碳、氮稳定同位素比值。研究人员在该漏油事件发生前、发生期间及发生后（2008年6月、2010年4月至7月），从密西西比-阿拉巴马沿岸与莫比尔湾的5个养殖位点采集了牡蛎壳样本；悬浮颗粒物样本则于相同或对应位点及时间区间内完成采集。油污样本取自佛罗里达-阿拉巴马州界至密西西比州佩蒂特博伊斯岛沿岸沉积物中的沥青球、油垫及半固态油污样品。针对所有样本，科研人员均测定了其碳、氮稳定同位素比值；此外，研究团队还针对牡蛎壳样本开展了6种常用于烃类污染检测的痕量与次量元素分析，涉及元素包括镉（Cd）、钴（Co）、钼（Mo）、镍（Ni）、钯（Pd）及钒（V）。
