View new CMGDS report form

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Walter Barnhardt

Affiliate Investigator(s): Tony Wilbur, MA CZM

Information Specialist(s): Seth Ackerman

Data Type(s): Imagery: Photo, Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Interferometric, Sonar: Multibeam, Sonar: Sidescan

Scientific Purpose/Goals: Geologic mapping of inner shelf to: 1) support management of habitat and ocean resources; 2) clarify the post-glacial history of sea-level change in the region; and 3) reconstruct coastal environments and quantify rates of change over the last few thousand years.


Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 2006-08-01

End Date: 2006-08-24

Equipment Used: Edgetech chirp subbottom profiler 512i, SEA SWATHplus-M 234 kHz, Klein 3000, Digital camera, Real Time Kinematic GPS

Information to be Derived: Sea floor map; Bathymetric maps;

Summary of Activity and Data Gathered: We collected 100% coverage of sea floor with bathymetry and sidescan sonar data (total mapped area 277 km2), and approximately 2340 km of closely spaced seismic reflection profiles. Cruise focused on nearshore areas in water depths of 5-50 m, mostly inside state waters. Intermittent problems with GPS reception caused numerous shutdowns, especially during first 10 days of cruise. Cause is uncertain but we suspect jamming by radar or other external source. Gear snagged many lobster pots, which are VERY thick in the survey area. See cruise log for details.
