Abstract:

This is a dataset containing the coast types and oil exposure dates along the Gulf of Mexico from longitude -97 to -83. Based on these information, the chemical concentrations before and after the oil exposure dates in sandy and muddy regions are also included. For each chemical and region, there is a concentration value before the exposure date and a concentration value after the exposure date. The original chemical concentration data is also included in this dataset. The original data is processed from BP and EPA sampling data. There are 252 separate sheets for 252 different chemicals. The sampling dates were from April 2010 to June 2012. This dataset is a result of estimating the chemical concentration changes before and after the oil exposure dates and the oil impact for different regions for BEACHES project.

Purpose:

The data set was created for identifying the coast type of the Gulf of Mexico from longitude -97 to -83. In addition, it also includes a result of estimating the chemical concentration changes before and after the oil exposure dates and the oil impact for different regions.

Data Parameters and Units:

chemical concentration: mg/kg; μg/kg; μg/L

Methods:

There are several methods used to create this data set. The two main methods are listed below: 1. Chemical concentration change (CCC) method to estimate the oil Exposure Date. REF-Xia et al, 2020 2. Statistic analysis, t test to evaluate our result

Error Analysis:

Error Analysis is inside the Exposure date.xlsx file.
