Dataset for: Use of chemical concentration changes in coastal sediments to compute oil exposure dates

This dataset contains sediment sampling data along the Gulf of Mexico for the BP (British Petroleum) oil spill from several studies. There are 164 separate sheets for 164 different chemicals. The sampling date was from April 2010 to December 2010. This dataset is used to estimate the oil impact date based on chemical concentration change for the Beach Exposure And Child Health Study (BEACHES) project. This dataset supports the publication: Xia, J., Zhang, W., Ferguson, A. C., Mena, K. D., Özgökmen, T. M., & Solo-Gabriele, H. M. (2020).
