The Coastal Program of the Delaware Department of Natural Resources and Environmental Control is conducting a bottom and sub-bottom imaging project to map the bottom habitat and sub-bottom sediments of Delaware Bay and River. The data collected for these efforts were integrated, with all other available benthic data, into geodatabases and Fledermaus 3D databases.
These databases are being used in the planning and reviews of Wetland and Sub-aqueous Lands Permit and Federal Constancy reviews being conducted by the State of Delaware, which include projects such as: navigational channel deepening and dredge spoil characterization, beach replenishment sand identification, potential alternate energy sitting, identifying marine protected areas (MPA's), and identifying essential fish habitat.
The 3D databases constructed to evaluate the subsurface sediment distribution of the Army Corp of Engineer's Delaware Main Channel Deepening Project for a Sub- aqueous Land Permit review and efforts to identify beach replenishment borrow site will be presented.
