USGS Coastal and Marine Geology Program

Field Activity Details for field activity 1975-031-FA

Other ID: none

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Bradford Butman

Affiliate Investigator(s): John Vermersch - MIT

Information Specialist(s):

Data Type(s): Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Replace instruments on moorings GBK2 and GBK3 and inspect mooring hardware.


Start Port/Location: Vineyard Haven, MA

End Port/Location: Woods Hole, MA

Start Date: 1975-12-04

End Date: 1975-12-06

Equipment Used: Bottom platform

Information to be Derived: Time series data;

Summary of Activity and Data Gathered: Replaced VACM (102) on GBK2; 1/2 in. chain showed no wear since deployment in September from USCGC HORNBEAM. Attempted to recover mooring GBK3 at the same site, but high swells strained hauling equipment so recovery attempt was aborted. Mooring was redeployed at its original position (40d51minN, 67d25minW).
