Phytoplankton, protozoans, nutrients, temperature, and salinity collected at stations C6* on the C-transect in Louisiana coastal waters May – October for the years 1994, 1996, 1998, 2001, 2003, 2008, and 2010.

Surface water phytoplankton and protozoan community data collected in 2010 from long term coastal Louisiana monitoring stations were analyzed in relation to similar data from 1994, 1996, 1998, 2001, 2003 and 2008 to explore whether there were changes in community composition or other effects due to oil or other factors. Nutrient, temperature, and salinity data were also analyzed for those years. Additional Data Contributors / Authors: Dr. Nancy Rabalais, Wendy Morrison
