Project Summary Sheet
Fiscal Year 2003 Project Summary Report
Project Title: Geochemical Monitoring of Restoration Progress
Project Start Date: October 1, 1999 Project End Date: September 30, 2004
Web Sites: SOFIA
Location (Subregions, Counties, Park or Refuge): Florida Bay, Everglades National Park
Funding Source: USGS's Greater Everglades Science Initiative (PBS)
Principal Investigator(s): Kimberly Yates
Supporting Organizations: Florida Marine Research Institute, Everglades National Park
Associated / Linked Projects: Historical Changes in Salinity, Water Quality and Vegetation in Biscayne Bay: Lynn Wingard
Overview & Objective(s): This project began in FY2000, and monitors changes in critical biogeochemical processes and water quality in Florida Bay as South Florida restoration proceeds. Project objectives include 1) productivity monitoring to assess restoration progress and its effect on critical environmental processes in the Bay, 2) performing Bay-wide, geochemical surveys bimonthly (salinity, pH, dissolved oxygen, total carbon and air:sea CO2 gas flux) to measure changes in these parameters during implementation of restoration, and to identify sustained water quality changes that may result in ecosystem stress, and 3) comparison of results from productivity monitoring efforts to historical cycles of salinity change, carbonate sediment accumulation, and distribution patterns of subaquatic vegetation and indicator species to help identify when restoration has been accomplished. Each of these objectives defines each of three corresponding project tasks.
Status: FY2000 efforts focused on measuring current seasonal rates of productivity (including carbonate sediment production, photosynthesis and respiration) in Florida Bay to establish baselines for these parameters from which to monitor restoration progress. Productivity and bimonthly geochemical monitoring was continued through FY2001, 2002 and 2003. Objective (and task) 3 was begun in 2003 focusing on comparison of results from productivity monitoring efforts to historical cycles of carbonate sediment accumulation. All field activities for this 5-year project are now complete. It is anticipated that only objective (and task) 3, and general synthesis of project information will continue during FY04.

Relevance to Greater Everglades Restoration Information Needs: High-resolution water quality data from bimonthly surveys will be used to calibrate salinity and ecologic response to hydrologic condition models, and will provide baseline water quality data to assess restoration impacts. Similarly, productivity monitoring of representative benthic habitats in Florida Bay provides baseline process rates from which to measure ecological response to water quality change.
