Hypoxia in the Gulf of Mexico
The following list provides access to information on streamflow and nutrient flux for the stations used to calculate flow and flux for the major subbasins of the Mississippi-Atchafalaya River Basin (MARB) for the period of record through water year 2007. This information extends the information provided by Aulenbach and others (2007) for the period of record through water year 2005 and uses the same approach and methodologies. These stations are located on the main stem of the Mississippi River or its major tributaries.
Graphs of the annual flux of dissolved nitrite plus nitrate, total nitrogen, total phosphorus, dissolved orthophosphate, and dissolved silica, along with concurrent annual streamflow are available for all of the above basins.
Specific information on the data and methodology used is provided by the following report sections from Aulenbach and others (2007).
