Other ID: CI 7-78-3
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Peter Popenoe
Data Type(s): Location-Elevation: Navigation, Seismics: Sparker, Seismics: Sub Bottom Profiler, Sonar: Sidescan
Scientific Purpose/Goals: Assess types and frequencies of environmental hazards that may be encountered on the northern Blake Plateau; study the shallow geologic section to define these geologic hazards using high-resolution geophysical profiling gear on a 28-km grid; and test the shipboard gravity system to obtain gravity coverage of the northern Blake Plateau.
