Tampa Bay Study | Data | Task 2: Water & Sediment Quality - Biogeochemical Cycles
Several Tampa Bay Study projects were designed to understand the impact of human activities on classic estuarine biogeochemical processes. The integrated science effort revealed that the classic estuarine biogeochemical cycles operating within Tampa Bay are controlled not only by the underlying geologic framework that sets some form of environmental boundary constraints, but also by unique climate and temporal forcing.

We also learned that episodic events, including tropical storms and winter cold fronts, can play a defining role in these estuarine processes and that the local flora and fauna may impart unique fingerprints on water and soil chemistry. The role of submarine groundwater discharge (SGD) within Tampa Bay, both in terms of a new component in constituent mass balance estimates or as a process implicitly responsible in the cycling of redox-sensitive trace elements, was also developed.
