Summary Information for Field Activity 2009-050-FA

Area of Operations: 1) Lake Qalluuraq, near Atqasuk, North Slope Borough, Alaska
2) Killarney Lake, near Fairbanks, Alaska
3) Goldstream Bill Lake, near Fairbanks, Alaska
4) Lake Teshekpuk, Alaska, United States, North America

Dates: July 07, 2009 to July 17, 2009

Chief scientist: Carolyn Ruppel

Objectives: Collect geochemical and geophysical data in methane-emitting lakes. Study the physics, chemistry and biology associated with methane emissions from lakes in areas of discontinuous and continuous permafrost in Alaska.

Type of Activity: Seismic profiling; Photography; resistivity, ground penetrating radar, cresistivity, ground penetrating radar, c

Information to be derived: location of seeps and gas-charged sediments
substructure of seeps
Geophysical imagery, thickness of lake thaw bulbs, pore water geochemistry, lake bottom sediment characteristics, gas compositions.

Summary: Chirp seismic on multiple lakes on the North Slope and 2 lakes near Fairbanks; radar data on Lake Q on North Slope and 2 lakes near Fairbanks; resistivity on Lake Q; cores and gas samples from Lake Q and Killarney Lake near Fairbanks.
