Field Activity Details for field activity 2010-018-FA

Other ID: H-3-10-AR (Menlo Park)

Status: Completed

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

Funding Program(s):

Location: Western Arctic Ocean;

Principal Investigator(s): Deborah Hutchinson, William Danforth

Affiliate Investigator(s): Brian Edwards, USGS-Menlo Park, CA

Information Specialist(s): William Danforth

Data Type(s): Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Multibeam

Scientific Purpose/Goals: Two-icebreaker US-Canada experiment to identify the outer limits of the extended continental shelf of each nation in the western Arctic Ocean.

Vehicle(s):

Start Date: 2010-08-03

Start Port/Location: Dutch Harbor, AK

End Date: 2010-09-05

End Port/Location: Barrow, AK

Equipment Used: GPS (wh), Knudsen echo sounder 320B/R, Simrad EM120

Information to be Derived: Bathymetric maps; Sea floor map; Sediment thickness maps;

Summary of Activity and Data Gathered: Collected 12 kHz Bathymetry (Simrad EM122) to identify the 2500-meter contour on widely spaced tracklines. Multichannel seismic profiles were collected aboard the LOUIS S. ST. LAURENT to map sediment thicknesses.

Staff: Thomas O'Brien

Affiliate Staff:

Notes: No WHSC staff were aboard the Canadian ice breaker LOUIS S. ST. LAURENT (J. Childs, USGS-Menlo Park, CA will be liaison aboard LOUIS).
