Description:

Abstract:

This data set contains the locations of boulder ridges greater than or equal to 1 meter in height in the Stellwagen Bank National Marine Sanctuary Region off Boston, Massachusetts, an area of approximately 1100 nautical square miles. The Stellwagen Bank NMS Mapping Project is designed to provide detailed maps of the Stellwagen Bank region's environmental habitats and the first complete multibeam topographic and sea floor characterization maps of a significant region of the shallow EEZ. The boulder ridges were identified using multibeam topographic imagery and backscatter intensity of the seabed and video and photographic images collected from 1994 to 2003.

Purpose:

Development of interpretive seabed maps, sea floor imagery, and a GIS database that are accessible to scientists, policymakers, managers, and the general public.

Process_Step:

Process_Description:

Boulder ridges were visually identified using the Stellwagen Bank sun-illuminated multibeam sonar image combined with backscatter intensity images, and where available, video and/or photographic imagery from the region and then digitized using the Editor toolbar in ArcMap.

Process_Step:

Process_Description:

The metadata was edited to remove errors as well as update some information. Edits include modifying the title to move the dataset name to the end of the title, adding the DOI link in the identification section, added the suggested citation, added supplemental information with link to the related field activity pages on CMGDS, added the USGS Thesaurus keywords, added keywords section with USGS persistent identifier as theme keyword, added online links to cross-references, replaced distribution liability with FSP statement, used a generic email address in metadata. The metadata date (20050822), but not the contact (except email and contact instructions) was updated. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. Links to the data were fixed with respect to case-sensitivity issues. (20230427)
