Summary: This licence has been issued for the scientific research application No.5554. The objectives of this project are to improve the understanding of methane cycling in Mackenzie Delta lakes and how it is affected by the changing water levels and to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine carbon and nutrient flow to the ocean. Improve un...

Summary: This licence has been issued for the scientific research application No.5457. The short-term objectives of this study are to: i) administer a health communication and risk perception survey tailored for the Inuvaluit Settlement Region (ISR) – the Inuvialuit Food Messages Survey; ii) capture Inuvialuit values and perspectives of the country food system through interviews and photos for research ...

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 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: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
Summary: The researchers want to develop a model for small Arctic lakes that will help them see how sensitive or vulnerable Arctic lake ecosystems are to various forms of disturbance, such as future climate change or water withdrawal. In order to develop their m...

Principal Investigator: Guo, Laodong
Licensed Year(s): 2005 2004
Summary: The purpose of this study is to collect river waters to determine the concentrations of dissolved organic carbon, particulate organic carbon, and nutrients, including nitrate, phosphate and silicate, and to examine their temporary variations related to c...

Summary: The Beaufort Sea shelf is very shallow and the Mackenzie River, which sends freshwater, nutrients, and particles onto the shelf, may have a large influence on its productivity. The main aim of this project is to determine the change in flocculation, part...

Licensed Year(s): 2007 2006 2005 2004 2003 2002
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: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...
