Mass. North Shore Seafloor Mapping Report Published
CZM and the U.S. Geological Survey (USGS) have published the third in a series of seafloor mapping reports. High-Resolution Geologic Mapping of the Inner Continental Shelf: Cape Ann to Salisbury Beach, Massachusetts <http://pubs.usgs.gov/of/2007/1373/> contains geographic information system (GIS) data, maps, and technical explanations of data collection, processing, and a discussion of the seafloor geology and topography from Cape Ann to Salisbury. The two previous reports, Nahant to Gloucester <http://pubs.usgs.gov/of/2005/1293/> and Boston Harbor <http://pubs.usgs.gov/of/2006/1008/> , were in released in 2006 and data from two additional areas-Hull to Duxbury and Northern Cape Cod Bay-are currently in the publication process. Data collection continued this summer for additional areas of the Massachusetts coast. In July, CZM and USGS completed a cruise aboard the R/V Megan Miller in Buzzards Bay, which enabled them to collect more than 350 square kilometers of geophysical (swath bathymetry, sidescan sonar backscatter, and seismic reflection) data from the seafloor. Additional surveys are planned for fall 2009 and summer 2010. Since 2003, this CZM/USGS cooperative program has mapped 1,700 square kilometers (650 square miles) of the Commonwealth's coastal ocean.
