Abstract:

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.

Purpose:

To categorize and evaluate the nearshore sampling data of oil spill chemical (OSC) concentrations in different environmental matrices within time-space specific categories.

Data Parameters and Units:

Dataset consists of 1 Excel file named “Chemical Concentrations“ which contains the spreadsheets named “Readme“, “categorization_OSCs“, and “dispersant_chemicals“. Thee worksheet “categorization_OSCs“ contains - Chemical Group or Chemical, Category [BTEX (refers to the chemicals benzene, toluene, ethylbenzene and xylene), metal mineral, polycyclic aromatic hydrocarbon (PAH) or other], MC252 Oil concentration [the raw oil from the Deepwater Horizon (DWH spill)], Units MC252 Oil, Weathered Oil mean concentration, Units Weathered Oil [, n value, Tar mean concentration, Units Tar, Sediments Post mean concentration, Units Sediments Post, Sediments Prior mean concentration, Units Sediments Prior, Sediments Un-impacted mean concentration, Units Sediments Un-impacted, Water Post mean concentration, Units Water Post, Water Prior mean concentration, Units Water Prior, Water Un-impacted mean concentration and Units Water Prior. Please note units of chemicals in solids are mg/kg oil, µg/kg oil, and units of chemicals in water are mg/L, µg/L, n value is the number of replicates/samples, and category refers to matrix type. The worksheet “dispersant_chemicals“ contains - CAS Registry Number (identifiers for chemical substances), Chemical Name (chemical name following the International Union of Pure and Applied Chemistry (IUPAC) nomenclature), Alias (common name), Flag (D = Detected, NM = Not Measured, ND = Not Detected).

Methods:

Data containing MC-252 oil physical and chemical parameters were downloaded from the Gulf of Mexico Research Initiative Information and Data Cooperative (GRIIDC), MC-252 Oil Characterization data file [Unique Dataset Identifier (UDI): BP.x750.000:0004; doi:10.7266/N7DN43GQ]. The environmental sampling data were downloaded from the U.S. Environmental Protection Agency’s (U.S. EPA) Deepwater Horizon oil spill response website (https://archive.epa.gov/emergency/bpspill/web/html/download.html).
