Delaware Bay Benthic Habitat 2010

These data represent the benthic habitat and sub-bottom sediments of the Delaware Bay and Delaware River. The data were compiled by a partnership among the Delaware Coastal Program of its Division of Soil and Water Conservation, now the Division of Climate, Coastal and Energy, within the Department of Natural Resources and Environmental Control; the University of Delaware; the Partnership for the Delaware Estuary; and the New Jersey Department of Environmental Protection. This project was initiated to better understand the distribution of bottom sediment types, habitat biodiversity, and most importantly, humans' impact on the bay bottom and its living resources. The project integrates the use of three types of acoustical systems: Roxann Seabed classification system, chirp sub-bottom profiling, and multibeam bathymetric mapping. Verification of the acoustic data with bottom and sub-bottom sediments was performed through the collection of core samples and underwater video images. The Delaware Bay project has four principal goals. The first goal is to determine the location and extent of oyster reef habitats in upper Delaware Bay to improve management of these commercial resources in Delaware and New Jersey. The second goal is to evaluate shortnose and Atlantic sturgeon habitats. Sturgeon exhibit an affinity for specific regions within the system, and a better understanding of these areas will help evaluate the impact of dredging and other activities. The third goal is to identify potential borrow sites for materials used in beach renourishment. The fourth goal is to utilize high-resolution bathymetry data to improve understanding of sediment movement and other human impacts on the bay. The layers available within the data download include: biotic, geoform, and substrate.
