Total petroleum hydrocarbon (TPH) data for mesocosm sediment samples

Sediment samples for total petroleum hydrocarbon (TPH) were collected 2019-06-17 to 2019-11-18 from a twelve tank experimental mesocosm system performed at Louisiana Universities Marine Consortium (LUMCON) in Cocodrie, Louisiana. Mesocosm tanks were treated with various concentrations of oil (characterized as high, medium, low, and no) on 2019-07-08. Sediment samples were collected at one time point before oiling and at seven intervals post-oiling to determine the impacts on marsh sediments.
