Abstract

Fluorescence and ultraviolet-visible spectroscopy were used to analyze dissolved organic matter (DOM) in Barataria Bay, Louisiana for fluorophores and chromophores that might be derived from crude oil or decomposing vegetation. DOM is the water-soluble portion of natural organic matter (NOM), and it interacts chemically with trace metals and hydrophobic organic compounds in aquatic ecosystems. The present study was undertaken to investigate both the short- and mid-term responses of a coastal marsh ecosystem to contamination from the Deepwater Horizon (DWH MC252) oil spill. Samples were collected from twenty-six oil contaminated and uncontaminated sites in Barataria Bay. Fluorescence excitation emission matrices (EEMs) and UV-Vis spectroscopy were used to determine the overall distribution of fluorophores and chromophores at each site. These data were complemented by dissolved organic carbon measurements.
