Other ID: MGL1407

Status: Completed

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

Funding Program(s): Law of the Sea - Outer Limits of the US Continental Margins (LQ000FQ)

Principal Investigator(s): Deborah Hutchinson, Nathaniel Miller

Affiliate Investigator(s):

Information Specialist(s): Matthew Arsenault

Data Type(s): Electro-Magnetic: Gravity, Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Multichannel, Seismics: Sub Bottom Profiler, Sonar: Multibeam

Scientific Purpose/Goals: To map sediment thickness in order to define the outer limits of the U.S. Extended Continental Shelf beyond 200 nautical miles; and to better understand landslide processes on the Atlantic margin.
