The slope analysis of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts was performed using the slope tool in the Spatial Analyst extension in ArcGIS 8.3. The slope tool calculates the maximum rate of change in elevation over a pixel and its eight neighbors for a surface. The slope calculations were carried out for the bathymetric grids of the seafloor of this region.
The slope analysis provides an interpretation of the seabed features in the highly variable geomorphology of the Stellwagen Bank National Marine Sanctuary region. The seabed geometry is variable due to its glacial origin and is important to the region's wide range of habitats and high biodiversity.

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, 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. Original edits on 20210816. An additional author name fix on 20210908. Links to the data were fixed with respect to case-sensitivity issues. (20230428)
