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...


Landscape scale flooding in the Great Slave Lake Plain: Expansion of lakes, flooding of wetlands and implications for bison habitat and local land users (Traditional knowledge study component)
Principal Investigator: Wesche, Sonia D
Licenced Year(s): 2012
Summary: The over-arching objectives of the project are to draw together multiple sources of information to (1) examine the change in lake area in this eco region, (2) quantify the type and amount of habitat loss or modification; (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change; (4) document local and traditional knowledge of physical and biologi...


Bluefish Lake Mercury Monitoring
Principal Investigator: Dewar, David J
Licenced Year(s): 2012
Summary: The Objectives of this research project are to: 1.) gather information in 2012 on the small-bodied and Young of Year fish in Bluefish Lake that may be available for monitoring as well as determine the most suitable methods and locations for their capture in order to finalize the proposed mercury study design, and 2.) complete monitoring between 2013 and 2015 as described in the finalized mercury ...
