The Tampa Bay Estuary Program (TBEP) was formed in 1991 to assist in developing a comprehensive plan to restore and protect
Tampa Bay in Florida, USA. An ecological indicator of the health of the Bay is the coverage of seagrasses, historically in
decline, which are important to the aquatic habitat and food web of the bay. Seagrass decline is linked to excess of
plant-stimulating forms of nitrogen to the bay, promoting algae growth, which shades out light needed to sustain seagrasses.
One element of the TBEP is a private-local-state, multi-agency Nitrogen Management Consortium that seeks to limit nitrogen
loading to the Bay to the 1992-1994 average. Present estimates suggest atmospheric deposition comprises ~ 30% of the
nitrogen budget of the Bay. This estimate was based, however, on limited ambient monitoring data and simple models, typical
of such national estuary program efforts nationwide.
In the Bay Regional Atmospheric Chemistry Experiment Florida DEP joined with TBEP to increase the intensity, sophistication
and spatial scope of monitoring and modeling and provide better information on air quality in the Tampa Bay area. The result
will be improved estimates of the effects of local and regional emissions of oxides of nitrogen (NOx) on the Bay and the
benefits to be gained from implementation of emissions reduction strategies.
