Lac Levis Aeromagnetic Survey
Principal Investigator: Kiss, Frank
Licensed Year(s): 2019
Summary: The objective of this airborne survey is to acquire high-resolution aeromagnetic data. This survey will be flown to improve our knowledge of the area. It will support potential future ground-based geological mapping and to provide basic information to support mineral exploration. The survey will consist of approximately 27,600 line km of surveying flown at a line spacing of 500 m (or 1,640 feet...

Taltson Hydroelectric Facility Aquatic Monitoring
Principal Investigator: Miller, Matthew
Licensed Year(s): 2019 2018 2017 2016
Summary: The objective of the monitoring and mitigation is to determine operating procedures and mitigation options for the annual shutdown at Taltson Hydroelectric Facility to minimize the environmental impact on downstream Trudel Creek. Various mitigation options have been and are being assessed and the results on Trudel Creek are being monitoring to determine the best operating procedure for the ann...

Ekati Engineering and Environmental Monitoring Programs
Principal Investigator: Pacholski, Laura J
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2019 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 of sprin...

Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objective of this research is to characterize the long-term (>50 years) climatic conditions and annual rate of mass change for the Melville ice cap, NWT. Glacier mass balance is defined as the difference between the amount of snow accumulated on a glacier (generally termed winter balance) and the amount lost due to melt (summer balance) over the course of a given year. Due to logistical co...

Hydrology of High Latitude Watersheds
Principal Investigator: Marsh, Philip
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this project are to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions; toconsider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes; and, to develop improved predictive models. These will allow a better understanding of the impact of climate change and/or n...

Teleseismic investigations of the crust and mantle structure beneath Banks Island, NWT
Principal Investigator: Audet, Pascal
Licensed Year(s): 2019 2018 2017 2016 2015
Summary: This project is aimed at understanding the structure and evolution of the crust and mantle beneath Banks Island in the western Arctic by analyzing new seismic data collected from an array of broadband seismic stations. The objective is to provide information on crustal and mantle structures to determine whether Banks Island forms a rifted margin, or forms the northern extension of the Canadian Shi...

Investigating the relationship between snow microstructure and airborne synthetic aperature radar measurements of tundra snow to improve environmental prediction capabilities in polar regions
Principal Investigator: Derksen, Chris
Licensed Year(s): 2019 2018
Summary: High resolution Ku-band synthetic aperture radar (SAR) has been proposed to measure Snow Water Equivalent (SWE) from space as part of the proposed Canadian Space Agency Terrestrial Snow Mass Mission (TSMM). An opportunity exists to advance the understanding of the Ku-band radar response to snow properties and develop improved retrieval algorithms using airborne sensors that replicate elements of t...

Capitalizing on long-term experimental manipulations to understand and predict arctic terrestrial ecosystem responses to climate warming
Principal Investigator: Grogan, Paul
Licensed Year(s): 2019
Summary: The objectives of this research project are: 1) to determine the biogeochemical and ecological significance of our discovery that mesic tundra plant growth can be co-limited by nitrogen (N) and phosphorus (P); 2) to predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivory, on tundra deciduous and evergreen shrub abundances; and, 3) to evaluate...

Future of Tundra-Atmosphere Climate Interactions
Principal Investigator: Lafleur, Peter M
Licensed Year(s): 2019
Summary: The overall goal of this project is to increase the knowledge of how tundra environments interact with the atmosphere and predict how changing tundra vegetation will affect future climates. Tundra ecosystems exchange energy, water and carbon gases with the atmosphere, which are important elements of the climate system. As tundra vegetation reorganizes in response to global warming, these exchange ...

Airborne laser mapping
Principal Investigator: Hopkinson, Chris
Licensed Year(s): 2019 2018
Summary: Collect airborne laser scanning data over biomass plots over NWT. Specifically to develop biomass and forest resource models for GNWT multi source inventory, and to assess how the resource is changing through time and in space due to climate and fire influences. Airborne laser data coverage is calibrated by field plot data (most provided by GNWT) and models are created which are then upscaled t...
