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. The knowledge generated from this multi- year program is integrated into regional impact studie...

Summary: The objective of this project is to document the physical condition of the seabed lease following the removal of the Tarsiut Caissons. The project also includes sampling benthic populations in the disturbed and undisturbed areas of the lease. This information can be used as a benchmark for possible future study of the effects of natural processes in restoring the footprint of the caissons. A bathy...

Summary: This research seeks to resolve the nature and potential source of kimberlite (diamond) indicator minerals, and to improve understanding of the geological history of Banks Island, and how this relates to off-shore geology and regional hydrocarbon systems. For the kimberlite (diamond) indicator mineral study, the research team will take up to 100 small (10-20 kg) samples of stream sediments and v...

Summary: The Objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. Specific activities for the coming field season include the following: (Goal 1) I...

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 regio...

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 purpose of the proposed study is to examine twenty-two historic well sites within the Inuvialuit Settlement Region, eight of which are located within the Kendall Island Bird Sanctuary. Investigations on six of the twenty-two sites will comprise geophysical surveys, and collection of benthic invertebrates, soil sediment, surface water samples, soil invertebrates and arthropods and plant tissue....

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Summary: This research will investigate: A) the physical and chemical characteristics of permafrost in the Mackenzie Delta region to identify areas of ice-rich permafrost or thaw sensitive terrain. Second; B) the effect of permafrost degradation on water quality...

Licensed Year(s): 2002 2000 1999
Summary: The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...
