Detailed, high-resolution maps of Florida Bay mudbank elevations are needed to understand sediment dynamics and provide input into water quality and circulation models. The bathymetry of Florida Bay had not been systematically mapped in nearly 100 years, and some shallow areas of the bay have never been mapped. An accurate, modern bathymetric survey provides a baseline for assessing future sedimentation rates in the Bay, and a foundation for developing a sediment budget. Due to the complexity of the Bay and age of existing data, a current bathymetric grid (digitally derived from the survey) is critical for numerical models.
Numerical circulation and sediment transport models being developed for the South Florida Ecosystem Restoration Program are being used to address water quality issues in Florida Bay. Application of these models is complicated due to the complex sea-floor topography (basin/mudbank morphology) of the Bay. The only complete topography data set of the Bay is 100 years old. Consequently, an accurate, modern sea-floor bathymetry map of the Bay is critical for numerical modeling research. A modern bathymetry data set will also permit a comparison to historical data in order to help access sedimentation rates within the Bay.
Florida Bay, FL
Number of soundings: 2,138,572 in comma-delimited and Esri point shapefile formats.
Single beam bathymetry (X,Y,Z) data. Products are ASCII text files of the sounding data and point shapefiles representing seafloor elevations.
This dataset includes bathymetric data south from the Florida Everglades to the Florida Keys and west from Key Largo to Marathon Key. All data were processed relative to the WGS84 (G1150) ellipsoid.
