Description:
This program is part of a larger program called ECOHAB: Florida that includes this study, physical oceanography, circulation patterns and shelf scale modeling for predicting the occurrence and transport of Gymnodinium breve red tides. The physical part of the program is funded out of NOAA and EPA and is operated by the University of South Florida, Department of Marine Science. The coordinated programs provide data to do large and small scale modeling of blooms.Objectives/Hypothesis:
- Determine the interactions of cellular, behavioral, life cycle and community regulation processes with environmental forcing factors during stages of bloom development.
- Model the biophysical interactions of G. breve red tides on the west Florida shelf at small scales (< 1 km) at the physiological level of G. breve's interaction with its chemical and physical habitat.
- Determine the sources of inorganic and organic nutrients that allow growth and persistence of large G. breve populations in coastal waters.
- Determine the production, occurrence, fate and effects of brevetoxins in the environment during and after G. breve blooms.
