Ekati Engineering and Environmental Monitoring Programs
Principal Investigator: Pacholski, Laura J
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2018 will be to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality, and 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 of spring fresh...


Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licenced Year(s): 2018 2017 2016
Summary: The research goal 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 modelled in the future. The fires of 2014 in the southwestern NWT provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration with an inter-university team ...


Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The broad goal of this research is to increase our understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since we 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 fluxes - the ex...


Comparing the snow depths and densities of different habitats in the Beaufort Delta region
Principal Investigator: Kasook, Davonna C
Licenced Year(s): 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will study the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical data (...


Understanding the potential impact of metals in aquatic systems.
Principal Investigator: McGeer, Jim
Licenced Year(s): 2017
Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...


Akaitcho - DUC Wetland Mapping Project
Principal Investigator: Richard, Alain
Licenced Year(s): 2017
Summary: The main objective of this project is to develop wetland inventory for south eastern Northwest Territories (NWT) that will be used to provide a baseline for many kinds of planning (including land use planning processes) and research in support of biodiversity conservation and sustainable management of habitat. Specific objectives are to: 1) develop and use computer-based methods to produce we...


Understanding changes in aquatic ecosystem health and water quality in the Fort Good Hope – Ramparts Area
Principal Investigator: Gurney, Kirsty E.
Licenced Year(s): 2017
Summary: This project aims to build community partnerships, identify field sites, and develop and implement sampling protocols for long term, community-based, monitoring of wetland ecosystems near Fort Good Hope. Whereas some wetlands in the study area have 1) already been, or 2) are likely to be, impacted by a wide range of industrial activities, including development of oil and gas and associated inf...


A Mass-Energy Analysis of Permafrost and Vegetation Change Across a Mackenzie Mountain Treeline Ecotone: 1944 to 2017
Principal Investigator: Kershaw, Geoffrey GL
Licenced Year(s): 2017
Summary: The objectives of this project are to assess changes in ice rich permafrost landforms and plant community composition across a treeline ecotone and relate those larger shifts to specific physically based estimates of energy-mass budget for such features. The distribution of permafrost and vegetation both vary through time and space across the treeline, and while changes in one will affect the othe...


Greenhouse Gas Exchange in the Outer Mackenzie Delta
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2017
Summary: The objective of this campaign will be to measure the emission/uptake of methane and carbon dioxide at Fish Island in the outer Mackenzie Delta over a full growing season. This data will be used to determine the carbon balance of the island, and estimate the carbon balance of the land surfaces in the outer Mackenzie Delta. Additionally, the research team will investigate factors influencing the ex...


NTPC Bluefish Hydro Repairs
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...
