Area of Operations: Teshepuk Lake, Alaska, United States, North America
Dates: April 14, 2010 to May 01, 2010
Objectives: Collect fluid and sediment samples to investigate sedimentary cycling of methane and to reconstruct the record of methane emissions for Lake Tesch, near Drew Point on the north slope of Alaska.
Type of Activity: Sampling
Information to be derived: Samples and chemical analysis
Summary: Cored and sampled four lakes in the vicinity of Lake Teschepuk -- Lake Teshepuk, Lake Helen, Lake 21 and Lake Koguru. Cores from each lake we processed for analysis of gases, fluids, sediments and biomarkers. Fluids have been processed for concentration analysis of dissolved CO2.
