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. Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine reserves, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay.
Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. They were collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005.
The purpose of this feature class is to qualitatively characterize the seafloor within the study area using five general physiographic zones. Geologic maps using these zones provide a regional view of the seafloor geology.
The minimum mapping unit is 2,500 square meters.

The accuracy of this interpretive data layer is dependant on the level of detail of the source material and interpretation procedures.
Topology was built to indentify any topological errors such as gaps between adjacent polygons. All topological errors were verified and corrected.
Survey data from USGS field activity numbers 05005 and 04015 were used as source data for these interpretations. The inshore boundary of this data layer extends shoreward of these source data. Source data for these shallow areas include aerial photographs and NOAA Nautical Charts. The aerial photographs were downloaded from MassGIS (http://www.mass.gov/mgis/).
A blank polygon geodatabase feature class was made using the bathymetric footprint from the nearshore (05005) and offshore (04015) data The westward boundary of the layer was extended to the shoreline that was extracted from NOAA nautical chart 13282 Newburyport Harbor and Plum Island Sound (10th Ed., Dec 9/95.) Five subtypes were added to the feature class to reduce coding errors during the digitizing process. The 50 meter depth contour was added to this polygon to establish the boundary between the Outer Basin and Near shore Ramp zones. Additional zones were digitized using the "cut polygon" under editing option. Each polygon was digitized at a general zoom scale of 1:12,000. All geoprocessing was completed within ESRI ArcMap 9.1 software.

Edits to the metadata were made to fix any errors that MP v 2.9.30 flagged. 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.). 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.
