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, ...

Principal Investigator: Hawkins, Jim R.
Licensed Year(s): 2007
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: 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...

Principal Investigator: Boyes, Donald M.
Licensed Year(s): 1995 1994 1990
Summary: The collection of the field data is required to calibrate satellite image clasifications and interpretations concerning water body measurements, plant community types, and sedimentation patterns. Field measurements will include measuring ground distances and recording plant characteristics. Nothing in the field area will be destroyed or removed....

Summary: Researchers will evaluate the spatial variability of nutrient chemistry during the snowmelt period within the drainage network of the tundra stream ecosystem. Evaluation of the controls on nutrient chemistry and community metabolism in streams withing the borel forest/tundra ecotone through the measurement of algae and organic matter in the stream. Evaluation of the potential role of Mackenzie De...

Summary: As part of a long term study, I will continue to examine the biology of arctic and subarctic insects. Information will be collected on insect distributions as well as insect adaptations to living in environments with extremely cold winters and short summers. Studies on insect communities in the north may be good indicators of global climate change since they are short-lived species with limited a...

Principal Investigator: Freeman, Milton M.R.
Licensed Year(s): 1994 1993 1992
Summary: Under the direction of the Aklavik and Inuvik HTA's, the research team will carry out interviews with Inuvialuit that are knowledgable about the broad whitefish and its fishery in the local waters. Data to be obtained include information on the traditional fishery, changes to this fishery, knowledge about the breeding and feeding habits, migrations, parasites and diseases, and effects of local en...

Principal Investigator: Langlais, Richard
Licensed Year(s): 1992
Summary: The researcher will interview a small number of people living and working in the eastern Arctic to discuss what ecological security means for different people and determine if there is any kind of ecologically significant ideas which could be applied in the future....

Principal Investigator: Macdonald, R.W.
Licensed Year(s): 1992
Summary: Funded by NOGAP, this ongoing project is addressing the transport of substances to and across the Beaufort Shelf including hydrocarbons, and the ecological processes with which oil exploration will interact. The dynamics of shorefast ice fields, shelf circulation and currents, vertical mixing processes, water properties, plant pigments in the water column and vertical flux of particles over the s...

Principal Investigator: Tarnocai, C.
Licensed Year(s): 1991
Summary: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....
