Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: Project a: essentially fifth year of research (sixth-year if associated work in 2000 is counted), and seeks to continue heretofore successful investigations into the nature, substance and long-term effects of contact between Copper Inuit and Europeans/Eurocanadians in the 19th and 20th centuries utilizing sociocultural, archaeological, and economic methodologies, b. Project seeks to initiate a col...

Summary: Several environmental and engineering studies were conducted between 2001 and 2006 to assess a proposed pipeline in the Mackenzie Valley. These studies will continue in 2007 and 2008. Route and site reconnaissance will be by helicopter, and crews will land at selected sites based on observations made during the flight. Reconnaissance surveys of road-water crossings will be performed. Pipeline-...

Summary: The objectives of this study are to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta, including the hydroclimatic conditions controlling their occurrence and associated floods, develop a hydraulic model of it, and investigate the importance of deep scour holes in the Mackenzie River. This study is an expansion of previous research conducted in 2004. Ice jamming has ...

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...

Summary: The main goal of this research is to use lake sediment records to examine changes in weather conditions and river discharge in the western Canadian Arctic during the past 2000 years, which will aid in understanding current conditions and forecasting future conditions. The research team will reach the study location by airplane from Resolute, Nunavut, and will be on site from late May to early ...

Summary: From 2001 to 2004, aquatics studies were done in the Niglintgak, Taglu and Parsons Lake lease areas and along the proposed gathering pipeline. In addition, aquatic studies at proposed infrastructure sites and borrow pits were initiated in 2004. The 2005 studies are a continuation of the work done in previous years. The work will include additional investigations into fish and fish habitat, hydrolo...

Summary: The Beaufort Sea shelf is very shallow and the Mackenzie River, which sends freshwater, nutrients, and particles onto the shelf, may have a large influence on its productivity. The researchers would like to study the effects of the river in transporting particles to the shelf by measuring the types of particles, how fast they sink, and how easily they are stirred from the bottom. They would also ...

Summary: This project is a continuation of work that began in 2004. The Niglintgak Gas Processing facility may be constructed on a seaworthy barge, transported to a staging site in the Beaufort Sea, and then towed through the Mackenzie Delta channels to a sheltered location in Little Kumak Channel where the barge set-down site is proposed. This study will look at the environmental conditions along the pro...
