Summary: For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...

Licensed Year(s): 2010 2009
Summary: This licence is being issued for the scientific research application no. 1013. The goal of this research is to distinguish the chemical and physical processes acting on different lakes on Melville Island in order to understand how the systems have developed through time. Of particular interest is the mechanism to explain how the lakes became salty after the last glaciation. Shellabear Lake ...

Licensed Year(s): 2008
Summary: This licence is issued for the scientific research application # 876. The objective of this research is to determine the impacts of predicted soil warming scenarios for the arctic on the availability of phosphate, nitrate-nitrogen and ammonium, which are important soil nutrients. The field portion of this research will consist of two weeks of collecting soil data and gauging and sampling (f...

Summary: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...

Summary: Summer 2005 field activities will focus on continuing multi-year studies of the modern hydrology and ecology of the Slave River Delta. The aim of this research is to improve knowledge of changes in lake water balance and chemistry and the subsequent responses of aquatic plants over seasonal and inter-annual time-scales under varying climatic and hydrological conditions. Overall, this information...

Principal Investigator: Grasby, Stephen
Licensed Year(s): 2005 2004
Summary: This project is a continuation of work begun in 2004. The researchers were not able to do their field work in 2004, and will try again in 2005. Historic mention is made of springs at Windy Point on the north shore of Great Slave Lake. The research team...

Principal Investigator: Guo, Laodong
Licensed Year(s): 2005 2004
Summary: The purpose of the study is to better understand how climate and environmental changes affect river water chemistry and material export fluxes, and in turn, how biogeochemical tracers can be used to examine the impacts and biogeochemical consequences of environmental changes. This is the second year of a three-year study. The researchers plan to sample the Mackenzie River starting in late Apri...

Principal Investigator: Wytrychowski, Scott I
Licensed Year(s): 2004
Summary: The Department of Fisheries and Oceans has issued to Diavik Diamond Mines Inc an authorization which contains specific conditions pertaining to the construction of the A1418 dike. The study includes 10 sampling sites located on two transects radiating fr...

Licensed Year(s): 2003 2002 2001 2000
Summary: The objectives of the research are to examine how changes in active layer depth influence groundwater and surface water chemistry in two subbasins of the Daring Lake basin in the headwaters of the Coppermine River Basin. In addition, a snow survey of th...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2003 1998
Summary: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...
