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.
