Principal Investigator: Thiessen, Eric
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5816. This research will be guided by three objectives: 1) determine the largest possible contribution of mantle-derived heat sources, 2) establish a modern structural and tectono-metamorphic framework, and 3) evaluate evidence for mantle-derived heat input. Studies will involve field observations and targeted small-vo...

Principal Investigator: Borrmann, Stephan P
Licensed Year(s): 2014
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...

Principal Investigator: Dunfield, Peter F
Licensed Year(s): 2013
Summary: The objective of this work is to conduct a one day reconnaissance study of the Smoking Hills area. Mineral, rock, water and soil samples will be collected. Geochemical properties and microbial communities will be analysed in the laboratory in order to characterize any potential features unique to this site that would warrant future, more detailed research. The site will be accessed by helicopt...

Principal Investigator: Neyedley, Kevin
Licensed Year(s): 2013
Summary: The purpose of the study is to examine the rocks near Blachford lake lodge to gain a better understanding of how they formed and why there are there. Initial mapping has shown that they are unusual with more iron and nickel in them than would be normally expected and we would like to look at them to better understand their history. There have been exploration companies interested in these rocks an...

Principal Investigator: Turner, Elizabeth C
Licensed Year(s): 2013
Summary: This project seeks to understand the ancient marine environments recorded in these rocks, and thereby to interpret this poorly known, dramatic time in North America’s tectonic evolution. The areas addressed will be those that were briefly described in 1993: 1 location is in Yukon Territory (YT) and 2 are in Northwest Territories (NWT). This work will complement licensed research currently under wa...

Principal Investigator: Moore, Kristin M
Licensed Year(s): 2012 2009 2003
Summary: The primary objective of the 2012 program is to obtain feedback from community members relating to Lac de Gras lake trout (Salvelinus namaycush) taste, texture, general condition and health. A secondary objective is to meet requirements set out in the Fisheries Authorization for Works or Undertaking Affecting Fish Habitat. Fish collection will primarily be conducted using nets set out on...

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 research team is interested in how climate change is impacting Arctic rivers. The team will make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try t...

Principal Investigator: Bromstad, Mackenzie J
Licensed Year(s): 2010
Summary: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...

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: St-Onge, Sonia M
Licensed Year(s): 2006
Summary: The spruce and jack pine forest stands in certain areas surrounding the site of Giant Mine, north of Yellowknife, show signs of poor health; stunted growth, early leaf drops, and yellowed foliage. These symptoms may be attributed to the emissions of sulphur dioxide (SO2) and arsenic trioxide (As2O3) that were released into the atmosphere from 1949 to 1999 as by-products to the roasting process use...
