This layer contains information on benthic habitats of the Choptank River study area using the Coastal and Marine Ecological Classification Standard (CMECS). Eleven different habitat types are represented as non-overlapping polygons, including Anthropogenic and Biogenic Oyster Reef and Rubble, and several bottom sediment classifications. The layer was developed based on the Maryland Bay Bottom Survey (MBBS) conducted by MD DNR (1974- 1983), and the Acoustic Survey by Maryland Geological Survey and NOAA Chesapeake Bay Office (2003- 2014). A bay-wide version of this layer is available from Maryland’s Mapping and GIS Data Portal (MD iMAP) as “Maryland Benthic Habitat - Chesapeake Bay Benthic Habitat”. |
