Approximately 127 km² of the inner shelf were mapped in the nearshore region between the 10m and 40-m isobath. Purpose: The purpose of this data set is to calculate a generalized sea floor bottom type using multivariate statistics, and high resolution depth (bathymetry) and acoustic backscatter (sidescan sonar) data. These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole Science Center. High resolution bathymetry, backscatter intensity, and seismic profile data were collected over 127 km² area covering a portion of the South Essex Ocean Sanctuary to characterize the surface and subsurface of the seafloor for regional geologic framework investigations. geophysical data were collected during two different surveys.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added the link to the data catalog page in the Identification section. Attempted to modify http to https where appropriate. Added the online link to the data in the distribution section. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The depth system definition was incomplete. Generic values (such as 9999) were used to meet the standard. Minor fixes to the attribute format for some attributes were needed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
