Summary: The western Arctic coast is among the most rapidly changing coastlines in the world and one of the most sensitive to climate change. The objective is to improve knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and reduce the impacts of natural changes and industrial or community development. Spring...

Summary: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into region...

Summary: The main objective of this study is to establish the degree of impact and spatial extent of specific oceanic storm surges within the coastal Mackenzie Delta over the past 40 years. This investigation will be completed by analyzing remote sensing imagery to create multiyear change maps. The resulting maps will then be correlated to historic water level and climate data and verified by field samples...

Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

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: 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 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...
