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.
