Field Activity 2003-301-FA

Identifier 2003-301-FA
Purpose This project addresses the collection and interpretation of data necessary to develop the present day bathymetry of the Loxahatchee River, and St. Lucie River regions. This project supports several SFWMD efforts including the proposed MFL development for the Loxahatchee and St. Lucie River MFLs and the Indian River Lagoon Feasibility Study. All of these state-mandated efforts would utilize data obtained from these surveys to develop hydrodynamic models, which are essential in understanding the ecological processes of each of these coastal systems. This project also supports other non-modeling efforts such as the determination of the oligohaline zones in the St. Lucie River systems.
Location Loxahatchee River and Lower St. Lucie River, FL
Summary Number of soundings: 107,106 in comma-delimited and Esri point shapefile formats.
Info derived Single beam bathymetry (X,Y,Z) data. Products are ASCII text files of the sounding data and point shapefiles representing seafloor elevations.
Comments This dataset includes bathymetric data for the northern sections of the North and Northwest Forks of the Loxahatchee River and Lower St. Lucie River. All data were processed relative to the WGS84 (G1150) ellipsoid.
