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: 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: This project will formulate a comprehensive history of the frequency and magnitude of floods and droughts and corresponding ecological responses in the Mackenzie Basin deltas over the past 1000 years. Results from this study will provide an essential dat...

Summary: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges for the Mackenzie Delta and 15 gauges for Hay River). These gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can be determined....
