Field Activity Details for field activity 1978-032-FA

Other ID: CI 7-78-3

Status: Completed

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

Funding Program(s):

Location: northern Blake Plateau, United States, North America, North Atlantic;

Principal Investigator(s): Peter Popenoe

Affiliate Investigator(s):

Information Specialist(s):

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.

End Date: 1978-10-19

End Port/Location: Miami, FL

Equipment Used: Teledyne single-channel 300-500J 40-tip minisparker, ORE 140 transceiver/1036 transducer sub-bottom profiler, Northstar 6000 LORAN-C, Single channel hydrophone, ORE sidescan
