Other ID: HUNT 02; Leg II
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): James M. Robb
Data Type(s): Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Boomer, Seismics: Sonobuoy, Sonar: Sidescan
Scientific Purpose/Goals: Cruise was the second part of the search for drilling sites along the north flank of Georges Bank.
Start Date: 1972-08-04
End Date: 1972-08-14
