Dataset for: Categorization of nearshore sampling data using oil slick trajectory predictions

This dataset contains oil spill chemical (OSC) concentration measurements for weathered oil, tar, sediment and water sampling data along the Gulf of Mexico collected by the EPA from April 30th to September 9th 2010. OSC concentration measurements from samples of MC-252, the raw oil from the Deepwater Horizon (DWH) spill were also included for the purpose of comparison. The environmental data were categorized into measurements of oil spill chemicals samples collected prior to oil spill impact, post-oil spill impact, and within unimpacted areas. The time-space categories were generated by comparing the dates and locations of the sampling data with the historic daily General NOAA Operational Modelling Environment (GNOME) trajectories for DWH oil slicks. Please note that each cell in the dataset provides a chemical’s concentration mean value calculated from various samples collected at different dates and locations along the Gulf of Mexico.

本数据集收录了2010年4月30日至9月9日由美国环境保护署（EPA）在墨西哥湾沿岸采集的风化原油、焦油、沉积物及水体样本的溢油化学品（Oil Spill Chemical, OSC）浓度监测数据。本数据集同时纳入了深水地平线（Deepwater Horizon, DWH）溢油事件的原始原油MC-252的样本浓度数据，用于对照分析。本数据集的环境数据被分为三类：溢油影响前采集的溢油化学品样本、溢油影响后采集的样本，以及未受溢油影响区域的样本。该数据集的时空分类通过对比采样数据的日期、位置与DWH浮油的每日通用NOAA作战建模环境（General NOAA Operational Modelling Environment, GNOME）历史轨迹生成。请注意，数据集中的每个单元格均代表基于墨西哥湾沿岸不同日期、不同地点采集的多组样本计算得到的单种化学品浓度均值。本数据集支撑以下发表文献：Montas, L.、Ferguson, A.
