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.
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
