Oil Composition and nutrients for the COAST mesocosm study, COASTal water with added coastal microbial concentrate

Mesocosm experiments were performed with seawater collected from the NGOM and enriched with coastal plankton collected from Galveston Bay. The four treatments in triplicate were analyzed for oil composition were 1) Control, 2) Water accommodated oil fraction (WAF), 3) Chemically enhanced (Corexit 9500) water accommodated fraction (CEWAF), and 4) 10-fold diluted CEWAF (DCWAF). The oil composition data presented here are EOE (estimated oil equivalence using fluorescence), PAH (polycyclic aromatic hydrocarbons), and Total PAH. Additionally, nutrients for these treatments are also included. Solid-state 13C NMR spectroscopic analysis data are available in GRIIDC dataset UDI: R4.x263.000:0022.
