High-Resolution Bathymetry of Florida BayEntry ID: USGS_SOFIA_Hi_res_bathy_FB
Abstract: The objective of this research was to collect new bathymetry for all of Florida Bay, digitize the historical shoreline and bathymetric data, compare previous data to modern data, and produce maps and digital grids of historical and modern bathymetry.
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 seafloor topography (basin/mudbank morphology) of the Bay. The only complete topography data set of the Bay is 100 years old. Consequently, an accurate, modern seafloor 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.

Access Constraints None
Use Constraints Uses of this digital geologic map should not violate the spatial
resolution of the data. Although the digital form of the data removes
the constraint imposed by the scale of a paper map, the detail and
accuracy inherent in map scale are also present in the digital data.
The fact that this database was edited for a scale of 1:24,000 means
... that higher resolution information is not present in the dataset.
Plotting at scales larger than 1:24,000 will not yield greater real
detail, although it may reveal fine-scale irregularities below the
intended resolution of the database. Similarly, where this database
is used in combination with other data of higher resolution, the
resolution of the combined output will be limited by the lower
resolution of these data.
