Sea Floor Maps Showing Topography, Sun-Illuminated Topographic Imagery, and Backscatter Intensity of Stellwagen Bank NMS Region off Boston, MA, USGS OFR 00-410

This data set contains the sea floor topographic contours,
sun-illuminated topographic imagery, and backscatter intensity
generated from a multibeam sonar survey of the Stellwagen Bank
National Marine Sanctuary region off Boston, Massachusetts, an area of
approximately 1100 square nautical 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.

Data were collected on four cruises over a two year period from the
fall of 1994 to the fall of 1996. The surveys were conducted aboard
the Candian Hydrographic Service vessel Frederick G. Creed, a SWATH
(Small Waterplane Twin Hull) ship that surveys at speeds of 16
knots. The multibeam data were collected utilizing a Simrad Subsea EM
1000 Multibeam Echo Sounder (95 kHz) that is permanently installed in
the hull of the Creed.

The data set includes Encapsulated PostScript, PostScript, Arc export,
Registered Tif, and Portable Document File formats of 3 individual
maps. See: "http://pubs.usgs.gov/of/of00-410/"
