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. For more information, see CZM's Seafloor
