Summary

The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 2, which is one of 18 similarly-sized quadrangles that comprise the 3,700 square kilometer (km2) SBNMS region. The seabed of the SBNMS region is a glaciated terrain that is topographically and texturally diverse. Mapping of quadrangle 2 shows the distribution of substrates across the southwestern part of Stellwagen Bank, in Stellwagen Basin to the west and southwest of the [...]

Purpose

This dataset provides comprehensive seabed interpretations of the seafloor within quadrangle 2 of the Stellwagen Bank National Marine Sanctuary region. This interpretation includes the geologic substrates, sediment mobility, substrate coarseness, and substrate mud content. The geologic substrates are the primary interpretations, and the remaining three are derivatives of that.
