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):

Information Specialist(s): Brian Andrews

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

Scientific Purpose/Goals: Geologic mapping of sea floor (geophysics only).


Start Date: 2007-07-23

Start Port/Location: Woods Hole, MA

End Date: 2007-08-08

End Port/Location: Woods Hole, MA

Equipment Used: Submetrix Sidescan sonar, EdgeTech Subbottom 512i, Real Time Kinematic GPS, SWATHplus-L 117 kHz, Klein 3000

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

Summary of Activity and Data Gathered: Survey collected 100% coverage with swath bathymetry over an area of approx. 350 km2 in northern Cape Cod Bay. Approx. 1300 line km of sidescan sonar and sub-bottom profiles were also collected. Preliminary data processing took place during survey.
