Client: Mississippi Department of Marine Resources
Artificial Reef Mapping Program. The Mississippi Department of Marine Resources (MDMR) contracted DEA Marine Services to survey 14 offshore Artificial Reef sites (Fish Havens) and eight Rigs to Reefs sites in the Gulf of Mexico. The objective of this survey was to provide detailed mapping of the permitted areas and develop an integrated geographic information system (GIS) database to support the State of Mississippi Artificial Reef Habitat Mapping Program. DEA’s survey of each site incorporated the use of a multibeam bathymetric sonar for detailed 3D mapping and a side scan sonar for high resolution 2D imaging to accurately map the permitted areas and identify significant features within the Fish Haven and Rigs to Reefs sites.
