Boulder ridges less than 1 m high on the sea floor of the Stellwagen Bank National Marine Sanctuary region (ridges0.shp)

This data set contains the locations of boulder ridges that are less than 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 environments and 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.
