Summary: The objectives of this research project are: (1.) To perform in-situ measurements of number concentrations, optical properties, and chemical composition of atmospheric aerosol particles with sizes between 3 nanometers and 10 micrometers. (2.) Identify aerosols of natural and anthropogenic origin. (3.) Quantify their relative contributions in dependency of particle size. (4.) Evaluate the pot...

Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic; the Mackenzie and Yukon Rivers in North America and the Ob', Yenisey, Lena, and Kolyma rivers in Russia. The researchers are interested in how climate change is impacting arctic rivers. The researchers will make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) an...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This license has been issued for the scientific research application #837. This study is designed to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic i...

Principal Investigator: Kuhnlein, Harriet V
Licensed Year(s): 2000
Summary: The Centre for Indigenous People's Nutrition (CINE) has developed the methodologies for analyses of nutrients in traditional food resources of Indigenous Peoples. It is recognized that risk and benefit assessments need to include information on food items as consumed. Databases used to process Arctic dietary data include both traditional food (TF) and market food (MF); while most MF items have n...

Principal Investigator: Hutchinson, Tom
Licensed Year(s): 1999
Summary: The purpose of this study is to re-measure the occurrences of vegetation, identifying all the different species and measuring them quantitatively in places that were measured 13 years ago. The focus this time will be on the ability of the tundra ecosystem to recover when a strong chemical stress ceases. The team will be flown in early August from Inuvik to the old DEW Line landing strip at Mallo...

Principal Investigator: Carolsfeld, Joachim
Licensed Year(s): 1996
Summary: The researchers propose to collect invertebrates, algae and microorganisms with the use of SCUBA, plankton nets, bottom dredges, and intertidal collection. These samples will be sorted and frozen for later analysis in Halifax. The researchers wish to collect samples in about 25 sites, ranging from the southern tip of Liverpool Bay to south of Saunatuk. All collections will take place from small...

Principal Investigator: Marsh, Philip
Licensed Year(s): 1993 1992 1991
Summary: The research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....

Principal Investigator: Ring, Richard A.
Licensed Year(s): 1993 1992 1990 1987
Summary: Professor Ring will continue an ongoing study on arctic insect cold-tolerance....
