Other ID: WF 80-2

Status: Completed

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

Funding Program(s):

Principal Investigator(s): David Twichell

Affiliate Investigator(s):

Information Specialist(s):

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

Scientific Purpose/Goals: Monitor the migration rates of sand waves within a 1.5 x 1.5 km area on Georges Bank.

Vehicle(s):

Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 1980-06-23

End Date: 1980-06-26

Equipment Used: Klein 531 sidescan, ORE 140 transceiver/1036 transducer sub-bottom profiler, Northstar 6000 LORAN-C, ATNAV acoustic transponder

Information to be Derived:

Summary of Activity and Data Gathered: Three acoustic transponders were deployed and surveyed in to define their positions relative to each other. After establishing the navigation grid, a sidescan sonar and 3.5 kHz echo sounding survey was completed to define the location and size of the sand waves. At the end of the survey, one transponder was recovered (#199) while the other two (#200?, 201?), which are marked by surface buoys, were left to serve as fixed references for the navigation nets of the next two surveys.
