Additional peer-reviewed publications that address wetlands and oil spills from Dr. J. A. Nyman’s research at Louisiana State University.
One experiment used soils from two types of fresh marshes (Sagittaria lancifolia and Panicum hemitomon), two types of oil (South Louisiana Crude and diesel), three types of animals (fish, aquatic crustacean, and benthic invertebrate), and four types of response options (no response, fertilizer, the dispersant COREXIT 9500, and the cleaner COREXIT 9580). This experiment resulted in the following three publications:
