Objective(s): To obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them.
Project Description: The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them. The fieldwork involves augering a hole in the lake ice and lowering a tube into the mud. The team will push this tube in with weights and then recover the sediment. With the equipment, the team can recover up to about 6 m of mud in a "core". The researchers will collect several sediment cores from each lake, and also take measurements of the water column conditions with electronic instruments (temperature, sediment load, salts, oxygen). The research team will forward publications to communities as they are completed. The Principal Investigator (PI) met several members of the Sachs Harbour community at an ArcticNet IRIS meeting in Inuvik in April, 2011 and was able to talk about this work. The PI hopes to have further opportunities to meet the community members in person, or to communicate as possible. The fieldwork for this study will be conducted from May 20, 2012 to May 27, 2012.
