Report for methane monitoring in Arctic Lakes in Northwest Territories, Canada, August 2017

The primary goal of the August 2017 field program was the recovery of nine year-long
OsmoSampler systems from eight lakes in the Mackenzie River delta and North Richards Island
regions of the Northwest Territories of Canada. Secondary goals for the field program included
collection of water and sediment samples from the same lakes, and deployment of new
OsmoSampler systems in three of the same lakes, as well as new sites of interest in the
Tuktoyaktuk region. Even despite poor weather in the outer delta and a cut line to an
OsmoSampler, all sampling systems that were deployed in August 2016 were successfully
recovered, as were sediment and water samples from the same lakes. These recoveries involved
numerous small boat trips to Inuvik area lakes and three helicopter days (supported by
collaborator Lance Lesack's PCSP award). New OsmoSamplers were deployed in three lakes: Lake 520 in the Inuvik area lakes, Swiss Cheese Lake in the outer delta, and North Head 1 lake
at the northern most point of North Richards Island. An additional OsmoSampler was deployed
in a deep hole by Scott Dallimore during operations off Tuktoyaktuk. During the field program,
the team was joined by freelance journalist Laura Poppick to develop articles related to our
Arctic research.
