Summary for Field Activity Number 2010-054-FA

Area of Operations: centered on Harrison Bay, shallow Beaufort Sea, Alaska, United States, North America, Arctic Ocean

Dates: August 03, 2010 to August 09, 2010

Objectives: 1) Image seafloor. 2) Map top of subsea permafrost in very near shore. 3) Survey for possible methane emissions at distal inferred end of permafrost offshore. 4) Collect data to help constrain whether seaward limit of permafrost is 'real' or related to a lithologic change.

Type of Activity: Seismic profiling
Seafloor mapping

Information to be derived: Sea floor map
Bathymetric maps

Summary: Transit from Prudhoe Bay West Dock to eastern Harrison Bay; collected seismic data along lines running NE-SW and long tie lines running WNW to ESE until weather turned bad.
