Summary: The goal of this project is to collect sediment cores and water samples from a lake, to be analysed as an indication of past snow melt and stream flow in the area. Two personnel will camp at the site for 5 days in late May. In late June, early July and/or late August they will return by helicopter from a neighboring camp in Nunavut for two or three visits, 3-4 hours each visit. A skidoo will be...

Summary: Specific activities for this field season include the following: (1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...

Summary: Melting permafrost can alter soils and surface runoff. The effects of such changes have been modeled but never evaluated experimentally. Arctic lake productivity is not well articulated and sensitivities to disturbance (e.g., climate change, water withdrawal for development use) remain unpredictable. The objective of this study is to develop a hydrologic model for melting permafrost conditions, as...

Summary: Climate change is expected to have the greatest impacts in northern regions. Permafrost degradation is a likely outcome of warming temperatures. As temperatures increase and permafrost begins to melt, there is likely to be significant impacts on aquatic communities as nutrients and contaminants accumulated in permafrost are released into lakes. This study will examine the impact of permafrost degr...

Summary: The Mackenzie Delta region is characterized by diverse terrain and ecological conditions. Responsible and effective management of oil and gas exploration and potential production and pipeline construction in this region necessitates a broad but detailed understanding of environmental conditions in this region and the potential response of this environment to climate change or anthropogenic disturb...

Principal Investigator: Douglas, Marianne
Licensed Year(s): 2002 2000 1999
Summary: The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...

Principal Investigator: Solomon, Steven M
Licensed Year(s): 1991
Summary: The Researcher and his team will use a hand-operated auger to take sediment cores and temperature measurements. Cores will penetrate the seabed beneath the ice to a depth of 2-3 metres. Ground Penetrating Radar (GPR) will be used to investigate ground ice distribution and a current meter will be used to measure sub-ice currents along the edge of the bottom-fast ice....

Principal Investigator: Smol, John P
Licensed Year(s): 1991 1990
Summary: The research team will sample approximately 20 lakes located within a 100 km radius of Tuktoyaktuk and within the immediate vicinity of Inuvik. At each lake they will analyze the water for major environmental variables and remove some of the lake mud for future analysis of algal remains....

Principal Investigator: Egginton, Paul A.
Licensed Year(s): 1992 1990
Summary: The team will install active layer monitoring stations at up to 8 sites on Richards Island. They will sample present active layer and surface permafrost for analysis of recent change as well as lake bottoms for similar reasons and a possible sea level record....

Principal Investigator: Taylor, John S.
Licensed Year(s): 1981
Summary: To total of 18 lakes will be studied and sampled to determine the importance of lake type to various fish populations. Fish will be sampled using weirs, gill nets, seines, fyke nets, minnow traps and trawl nets....
