Field Activity Details for field activity 2003-301-FA

Other ID: none

Status: Completed

Organization(s): USGS, St. Petersburg Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Mark Erik Hansen

Affiliate Investigator(s):

Information Specialist(s): Nancy DeWitt

Data Type(s): Location-Elevation: Navigation, Sonar: Single Beam

Scientific Purpose/Goals: 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.

Vehicle(s): None

Start Port/Location: Loxahatcheee River, FL
