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 Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...

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 research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....
