Description:
Abstract:
The U.S. Geological Survey has conducted geologic mapping to characterize the sea floor offshore of Massachusetts. The mapping was carried out using a Simrad Subsea EM 1000 Multibeam Echo Sounder on the Frederick G. Creed on four cruises conducted between 1994 and 1998. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick.
The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) project that presents images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys that will serve the needs of research, management and the public.
Purpose:
This shapefile shows sea floor bathymetry as contours at 10-meter intervals in the area of multibeam data in Massachusetts Bay. The contours were derived from a 30-meter resolution ESRI grid of multibeam data (mb_bathy30m), smoothed over a 9 cell by 9 cell rectangle using the Focalmedian routine. This smoothing produces contours appropriate for display at a scale of 1:125,000 (used for USGS Map I-2734).
