U.S. Geological Survey Open-File Report 2012-1006

High-Resolution Geophysical Data From the Inner Continental Shelf at Vineyard Sound, Massachusetts


Summary

Skip past contents information

The U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM) conducted three surveys between 2009 and 2011 to map approximately 340 square kilometers of the inner continental shelf in Vineyard Sound, Massachusetts. The program focuses on the inshore waters of coastal Massachusetts primarily in water between 3 and 30 meters deep. The data published in this report include swath bathymetry from interferometric sonar, acoustic backscatter from sidescan sonar, and seismic-reflection profiles from a chirp subbottom profiler. These data were collected to support research on the influence of sea-level change and sediment supply on coastal evolution and sediment transport processes and to provide baseline seabed characterization information required for management of coastal and offshore resources within the coastal zone of Massachusetts. This report publishes the spatial data collected during this project and details the methods used to collect, process, and analyze these data.
