Biogeochemical controls on the structure and functioning of low arctic ecosystems
Principal Investigator: Grogan, Paul
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
Summary: The long-term goal of this research over the next 15-20 years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by these perturbations including climate change, and resource development and extraction. This research will work to answer the following questions: 1) Apart from birch, which other spec...


EKATI Engineering and Environmental Monitoring Programs
Principal Investigator: Hayward, April
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2017 to 2021 will be:1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality; and 2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 2.5L Niskin (a cylindrical PVC water sampler). During the week o...


Impacts of wildfire extent and severity on caribou habitat
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2017 2016
Summary: The objective is to improve the empirical foundations for predictive caribou habitat mapping within the forested areas of the Taiga Plains and Taiga Shield Ecoregions in the Northwest Territories, roughly south of Great Bear Lake. The research team will establish a network of long-term study plots across a range of fire characteristics and vegetation types, where the team will measure the rate and...


The frontline of permafrost thaw: a transect of eddy covariance towers across the southern Taiga Plains to better understand changing regional carbon and water budgets
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015
Summary: Through this project the research team will address the following objectives: 1) determine the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the sporadic and discontinuous permafrost zones; 3) determine if s the reported decrease (increase) in net carbon dioxide (methane) exchange...


Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2017
Summary: The broad goal of this research is to increase the understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since the research team are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories: 1. Tundra-atmosphere ...


Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licenced Year(s): 2017 2016
Summary: The goal of this project is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modeled in the future. The fires of 2014 in the southwestern Northwest Territories (NWT) provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration ...


AirMeth
Principal Investigator: Hartmann, Jörg
Licenced Year(s): 2016 2013 2012
Summary: The objectives of this survey are to establish patterns of methane (CH4) concentration in the atmosphere over the Mackenzie delta region and to quantify the emission of CH4 from these areas. Together with the data from previous data the research team should be able to estimate the annual contribution of the Mackenzie delta region to the atmospheric methane budget. Furthermore the research team wil...


Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licenced Year(s): 2016
Summary: The main objectives of this research are to: 1. monitor the spatial variability of soil moisture at approximately a 10km resolution in the region of Trail Valley Creek (TVC); and, 2. to test the soil moisture retrieval algorithms in high organic soils through both satellite based measurements and with the use of a ground based radiometer. To achieve the first objective, the research team will...


Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M

Summary: The broad goal of this research is to increase understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since the research team are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories: 1. Tundra-atmosphere flux...


Satellite Monitoring for Assessing Resource Developmentā€™s Impact on Bathurst Caribou (SMART)
Principal Investigator: Chen, Wenjun
Licenced Year(s): 2015
Summary: We have two specific objectives over the next three years: 1) to improve the understanding of the mechanisms responsible for the zone of influence (ZOI) from resource development disturbed areas in the Bathurst caribou habitat, and their relationships with caribou habitat use and productivity, by integrating traditional knowledge, field surveys, and remote sensing technology; and, 2) to investig...
