Field Activity Details for field activity 1979-031-FA

Other ID: NE-06

Status: Completed

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

Funding Program(s):

Principal Investigator(s): David Twichell

Affiliate Investigator(s): David Aubrey - WHOI

Information Specialist(s):

Data Type(s): Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Boomer, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Single Beam

Scientific Purpose/Goals: Sidescan sonar and high-resolution seismic profiling were done in the nearshore zone (3-30 m water depth) off Nauset Inlet and Coast Guard Beach to map the types and extent of nearshore bedforms and to define the late Pleistocene and Holocene history of the area.


Start Port/Location: Chatham, MA

End Port/Location: Chatham, MA

Start Date: 1979-09-27

End Date: 1979-10-03

Equipment Used: 12 kHz, Grab sampler, Single channel hydrophone, Northstar 6000 LORAN-C, EG&G 234, Motorola Mini-Ranger III, Edo Western Sidescan and 2.5 kHz sub-bottom system
