The study area includes the inner continental shelf generally out to approximately the 20 m isobath and shore of the region between Cape Henlopen, Delaware and Ocean City Inlet, Maryland. The study was conducted and is presented in five parts: 1) benthic habitat mapping and resource evaluation of potential sand mining areas, 2) a review of transitory species of fishes, sea turtles, and marine mammals that visit the study area, 3) a review of reproductive finfish and icthyoplankton that utilize the area, 4) a study of the potential modifications to waves due to dredging and other oceanographic considerations, and 5) an analysis of the long term trends and short term variability of the Maryland-Delaware shoreline. Part 1 required a substantial field effort including two cruises with collection and subsequent analysis of myriad samples and photographic or similar images of the bottom. Parts 2 and 3 primarily were reviews of the appropriate literature. Part 4 involved acquisition and analysis of historical wave and current information, reformatting of existing bathymetric data, and substantial computer modeling and analysis. Part 5 is a synthesis and interpretation of a varied suite of generally unpublished data.
