Monitoring and Assessment of Coastal and Marine Ecosystems in the Northern Gulf: historical database of trace metal, nutrients, chlorophyll-a and hydrographic data in the Mississippi Bight and Sound from October 2007 to November 2011

Historical database of dissolved (<0.45 µm) and truly dissolved (<0.02 µm) trace metals (Mo, Ba, U, Re, V, Fe, Cs, Cr, Mn), nutrients (NH4+, NO2-, NO3-, PO4, Si), chlorophyll-a, and hydrographic data (temperature, salinity, density, dissolved oxygen) in surface and bottom waters at eight fixed stations within the Mississippi Sound and Bight. Samples were collected as part of the University of Southern Mississippi project Monitoring and Assessment of Coastal and Marine Ecosystems in the Northern Gulf, which was funded by NOAA through the Northern Gulf Institute. Sampling was almost once every month from October 2007 to November 2011.
