USGS Open-File Report 2007-1080 - Streamflow and Nutrient Fluxes of the Mississippi-Atchafalaya River Basin and Subbasins for the Period of Record Through 2005

Graphics of Monthly Nutrient Flux and Concurrent Streamflow to the Gulf of Mexico

The following graphs depict monthly flux of dissolved nitrite plus nitrate (figure 1), total nitrogen (figure 2), total phosphorus (figure 3), dissolved orthophosphate (figure 4), and dissolved silica (figure 5), along with concurrent annual streamflow delivered to the Gulf of Mexico by the Mississippi-Atchafalaya River Basin.

Figure 1. Estimated monthly dissolved nitrite plus nitrate flux as N to the Gulf of Mexico and monthly mean streamflow, for October 1995 through September 2005.	Figure 2. Estimated monthly total nitrogen flux as N to the Gulf of Mexico and monthly mean streamflow, for October 1995 through September 2005.
Figure 3. Estimated monthly total phosphorus flux as P to the Gulf of Mexico and monthly mean streamflow, for October 1995 through September 2005.	Figure 4. Estimated monthly dissolved orthophosphate flux as P to the Gulf of Mexico and monthly mean streamflow, for October 1995 through September 2005.
Figure 5. Estimated monthly dissolved silica flux as SiO2 to the Gulf of Mexico and monthly mean streamflow, for October 1995 through September 2005.
