Cape Ann to Salisbury Beach Seafloor Mapping Data Published
CZM and USGS have published the first in a series of seafloor mapping reports, High-Resolution Geologic Mapping of the Inner Continental Shelf: Cape Ann to Salisbury Beach, Massachusetts. The report (USGS OFR 2007-1373) was prepared as part of the cooperative mapping program between CZM and USGS. Available online, the report contains geographic information system data, maps, and technical explanations of data collection, processing, and geologic interpretation. The next report in the series, Duxbury to Hull, is due out in 2010.

Buzzards Bay Geophysical Survey
The USGS/CZM geological mapping project completed a cruise aboard the R/V Megan Miller in Buzzards Bay. We collected geophysical data along 3350 km of trackline. Full coverage bathymetry and backscatter data encompass approx. 350 sq. km, including 29 sq. km in eastern Vineyard Sound.

Merrimack Embayment - coring survey
USGS completed a cruise aboard the R/V Connecticut to collect cores and subbottom profiles from the Merrimack Paleodelta and Jeffereys Ledge. These data will help reconstruct the depositional environments and determine sea-level history for the region.

South Shore & Cape Cod Bay - sampling & coring cruise
We completed a sampling survey aboard the R/V Connecticut to ground-truth the previously collected geophysical data. We used the USGS' SEABOSS sampling system to collect seafloor sediments, bottom photographs and video and a Rossfelder vibracorer for coring.

Northern Cape Cod Bay - geophysical survey
The 2nd phase of the Northern Cape Cod Bay mapping was completed aboard the R/V Megan Miller. This cruise collected 100% coverage with swath bathymetry over an area of approximately 350 sq km as well as sidescan-sonar backscatter and seismic-reflection profiles along 1,300 linear kilometers.

South Shore - nearshore geophysical survey
The 2nd phase of the South Shore mapping project was completed this week aboard the R/V Rafael. This cruise filled in areas not covered by 2006 Megan Miller survey, mostly in the shallow water along coast, from Green Harbor to Scituate, MA. We collected full coverage of swath bathymetry and sidescan-sonar backscatter as well as a closely spaced grid of seismic-reflection (subbottom) profiles. A total of 525 linear km of data covered approximately 57 sq km of the seafloor in water depths of 4-20 m.

MA Seafloor Mapping Project Expands to South Shore and Cape Cod Bay
Since its beginning in 2003, the cooperative seafloor-mapping project in Massachusetts has mapped the geology of 897 km² (346 mi²) of the coastal ocean, mostly inside the 3-mi limit of State waters. The project, jointly undertaken by the U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management, has expanded to cover new areas this year and brought in several new partners.
The latest phase of mapping began in August 2006 with a 3-week research cruise aboard the R/V Megan Miller. The 100-ft vessel was outfitted with geophysical systems and two mobile laboratories that allowed for data acquisition and onboard processing in near-real time. The survey focused on shallow-water (less than 50 m deep), nearshore areas along the South Shore coast from Hull to Duxbury, where we collected more than 2,300 km of trackline geophysical data covering an area of 270 km².

Boston Harbor Seafloor Mapping Data Published
CZM and USGS have published the second in a series of seafloor mapping reports, High-Resolution Geologic Mapping of the Inner Continental Shelf: Boston Harbor and Approaches, Massachusetts. The report (USGS OFR 2006-1008) was prepared as part of the cooperative mapping program between CZM and USGS, with hydrographic data provided by the NOAA. Available online, the report contains geographic information system (GIS) data, maps, and technical explanations of data collection, processing, and a discussion of the seafloor geology and topography of the study area. The first report, Nahant to Gloucester, was in released in February 2006.

South Shore & Cape Cod Bay - geophysical survey
We completed the 1st phase of mapping for the South Shore and Northern Cape Cod Bay survey areas this week aboard the R/V Megan Miller. Approximately 270 km² (104 mi²) of the inner shelf were mapped with high-resolution acoustic technologies including swath bathymetry; sidescan sonar backscatter; and seismic-reflection data.

Federal/State Cooperative to Map Seafloor Geology Continues
Researchers at the U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center are producing high-resolution maps of the sea-floor geology off the Massachusetts coast, with a focus on the nearshore region in water depths of less than 40 m. The mapping program is a cooperative effort involving the USGS, the Massachusetts Office of Coastal Zone Management (CZM), and the National Oceanic and Atmospheric Administration (NOAA)...

High-Resolution Geologic Mapping of the Shallow Seafloor off Massachusetts
The USGS Woods Hole Coastal and Marine Science Center, MassCZM & NOAA is conducting geophysical surveys to characterize the bottom morphology, surficial-sediment distribution, and subsurface geology in the shallow coastal waters off Massachusetts.
The long-term goal of this mapping effort is to produce high-resolution geologic maps that will be used in aggregate-resource and benthic-habitat studies by State and other Federal agencies. Three nearshore survey areas between Boston and the Massachusetts-New Hampshire State line were initially identified by CZM for study. These survey areas, which are inshore of the Stellwagen Bank multibeam-echosounder survey conducted previously by the USGS, include Boston Harbor and approaches, the South Essex Ocean Sanctuary, and the Southern Merrimack Embayment.
