Description: The Sensitive Areas Scallop dataset shows areas within Maryland's Coastal Bays that are significant for Scalloppopulations. The assumption is that an area's importance to Scallops is related to the density of SAV beds. The data set is based on 1999 Submerged Aquatic Vegetation (SAV) coverage dataset that was produced at the Virginia Institute of Marine Science from aerial photography flown in 1999. It is a portion of the full SAV dataset that extends back to 1971. Areas with a bed density of 1 and 2 (rank=5) were more important than those areas with a density of 3 (rank = 3).

Description: This table contains an attribute indicating sea scallop abundance for OCS blocks. It can be joined to an OCS block feature class to show the conservation priority attribute spatially. The source data are from the National Marine Fisheries Service sea scallop survey from 1994-2006.More information on the sea scallop fishery can be from from NMFS: http://www.nmfs.noaa.gov/fishwatch/species/atl_sea_scallop.htm
