Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from the Northwest Territories
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: This study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the research team have been studying since the early 1990s. The research team plan to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area). The team also plan to collect burbot from the Lutsel K’e and Fort Resolution ar...


Enhancement and monitoring of arctic grayling spawning habitat at Providence Creek, NWT
Principal Investigator: Low, George
Licenced Year(s): 2016 2015 2014
Summary: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...


Baseline Monitoring of Arctic Vegetation and Snow Changes over the Bathurst Caribou Habitat using Satellite Remote Sensing and Community-based Field Observations
Principal Investigator: Chen, Wenjun
Licenced Year(s): 2014 2013
Summary: The goals of this research project are: 1. To fill the information gap on Bathurst caribou summer range conditions using satellite remote sensing data and community-based ground vegetation monitoring 2. To develop a cumulative impact assessment method that makes cumulative impact assessment possible even if data are incomplete and provides timely feedback for guiding the refinement of monitoring...


EL462 & EL463 2013-2014 Biolophysical Baseline Study
Principal Investigator: Hansen, Ken
Licenced Year(s): 2013
Summary: The objective of the project is to identify the fish species present, and to gather population data on surveyed species, in waterbodies in the area of Husky’s proposed exploration activity. Four streams and four to seven small lakes are proposed to be assessed. The Cumulative Impact Monitoring Program recommended selecting 2-4 streams appropriate for collection of baseline information that can...


Controls on carbon and nutrient cycling in arctic tundra
Principal Investigator: Grogan, Paul
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Summary: The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...


Remote Sensing of Arctic Vegetation Biochemistry
Principal Investigator: Kennedy, Blair E
Licenced Year(s): 2014 2013
Summary: The objectives of the research are: (1) measure the spectral properties (i.e. how light is absorbed and reflected) and biochemical constituents (e.g. chlorophyll, water, nitrogen, carbon) of arctic vegetation at the ground-level in various vegetation communities across the Western Arctic (e.g. low-arctic to high-arctic); (2) investigate the potential of using satellite based multi-angular imaging ...


Impacts from climate change on berry productivity in the Canadian Arctic: Integrating community participation with science
Principal Investigator: Henry, Greg H R
Licenced Year(s): 2013 2012
Summary: The main objective of the Berry Project is to establish a long-term community-based monitoring program in arctic communities using culturally important berry species as indicators of climate change. The project’s main objectives for the Daring Lake Tundra Science Camp are to bring awareness to the effects of climate change and to expand environmental stewardship. These goals can be achieved by del...


Assessment of the Boloria chariclea complex
Principal Investigator: Leski, Michael L
Licenced Year(s): 2013 2011
Summary: The primary objective of this project is to collect B. chariclea arctica from sites in the Yukon and Northwest Territories. A network of haplotypes will be constructed, based on the mitochondrial cytochrome c oxidase subunit I (COI) gene, and a mismatch analysis will be performed to determine if genetic structure has been influenced by a sudden expansion in population size or long term stability. ...


Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: Through this project the research team will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale ...


Lichen Sampling Program - Diavik 2013
Principal Investigator: Wells, David A
Licenced Year(s): 2013 2010 2005
Summary: The aim of this research project is to determine whether dust generated from mining activities is causing a measurable change in dust deposition to and/or metals uptake in lichen closer to and further from the mine. If a significant difference in uptake is noted closer to versus further from the mine, a health risk assessment to caribou may be conducted to determine risks associated with consumpti...
