Project Description

Our initial studies of the impacts of Deepwater Horizon oil (DHO) have shown that some members of the marine phytoplankton collected from coastal Louisiana waters grow well in seawater containing as much as 100 parts per million wellhead DHO. Control studies show that these assemblages, consisting primarily of chlorophytes, differ markedly from the diatom-dominated community that develops in the absence of DHO.
