Summary Information for Field Activity 2010-018-FA

Area of Operations: Western Arctic Ocean

Dates: August 03, 2010 to September 05, 2010

Chief scientist: Deborah Hutchinson

   Brian Edwards, USGS-Menlo Park, CA

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

Type of Activity: Sea floor mapping; Sampling; Bathymetric and Seismic mapping;Bathymetric and Seismic mapping

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

Summary: 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.
