Description:

Abstract:

The maps show the surface salinity for Florida Bay at 5ppt salinity intervals approximately every other month beginning in November 1994 through December 2001 and the bottom salinity for 1994-1996.

Purpose:

Recent algal blooms and seagrass mortality have raised concerns about the water quality of Florida Bay, particularly its nutrient content (nitrogen and phosphorous), hypersalinity, and turbidity. Water quality is closely tied to sediment transport processes because resuspension of sediments increases turbidity, releases stored nutrients, and facilitates sediment export to the reef tract.

The objective of this research is to provide a better understanding of how and when sediments within Florida Bay are resuspended and deposited, to define the spatial distribution of the potential for resuspension, to delineate patterns of potential bathymetric change, and to predict the impacts of storms or seagrass die-off on bathymetry and circulation within the bay. By combining these results with the findings of other research being conducted in Florida Bay, we hope to quantify sediment export from the bay, better define the nutrient input during resuspension events, and assist in modeling circulation and water quality. Results will enable long-term sediment deposition and erosion in various regions of the bay to be integrated with data on the anticipated sea-level rise to predict future water depths and volumes. Results from this project, together with established sediment production rates, will provide the basis for a sediment budget for Florida Bay.

Process_Step:

Process_Description:

The USGS conducted salinity surveys of Florida Bay approximately every other month from November 1994 through December 2001. The data collected during the surveys were supplemented with point data from Everglades National Park marine monitoring continuous stations and the South Florida Water Management District water quality monitoring stations collected by the Southeast Environmental Research Program at Florida International University from 1994 through 1997. The data were assembled and contoured using CPS3 (Contour Plotting System) software version 4.2 and ARC/INFO 7.0.3 to produce maps of the surface salinity in Florida Bay. Data points are shown on the maps. Surveys typically took between 3 and 5 days, depending on weather. Between 1994 and the summer of 1996 each survey collected salinity data at between 250 and 350 stations each consisting of a surface measurement 15 cm below the surface and a measurement on the bottom.

During the summer and fall of 1996, the USGS developed a digital measuring system so that subsequent surveys collected several thousand surface measurements. Due to the new digital system, the USGS no longer uses the South Florida Water Management District data nor the Everglades National Park data. Bottom salinity surveys were discontinued after December 1996.
