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
Licenced Year(s): 2018
Summary: New high resolution Ku- and Ka-band synthetic aperture radar (SAR) measurements are being proposed to measure tundra snow water equivalent (SWE) from future space-borne sensors, however further work is necessary to test the mission concept using airborne instruments that replicate the proposed satellite sensors. During the winter of 2012-2013 a research campaign at the Trail Valley Creek study sit...


Taltson Hydroelectric Facility Aquatic Monitoring
Principal Investigator: Miller, Matthew
Licenced Year(s): 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...


Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this study are to estimate the amount of water equivalent mass the Melville South Ice Cap loses (or gains) on an annual basis, and to derive a long-term climate record from glacier measurements and weather station data in order to determine trends in climate change for this region of the NWT. Mass balance is measured at each of the ~21 poles across the ice cap as function of s...


Hydrology of High Latitude Watersheds
Principal Investigator: Marsh, Philip
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern region;, 2) to consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes, and 3) to develop improved predictive tools or models. These will allow a better understanding of the impact of clim...


Exploring the Effectiveness of Vegetation for Water Sewage Treatment
Principal Investigator: Simon, Angel
Licenced Year(s): 2018
Summary: The objective of this study is to assess the efficiency of the common cattail in the removal of nitrogen and phosphorus forms from wastewater to aid in the improvement of the sewage lagoon at the Inuvik Wastewater Treatment plant. Common cattail seeds will be placed in a germination chamber at Aurora Research Institute for four weeks, with watering and rotation of the plants being done twice a...


Southern Mackenzie Surficial Mapping
Principal Investigator: Paulen, Roger C.
Licenced Year(s): 2018 2017
Summary: Activities in the study are focused on making a map of the surface sediments. The map will help to understand surface material distribution and thickness, how these materials were deposited by glaciers, and where the bedrock outcrops. Soil samples will be collected across the study area. The mineralogical and geochemical analyses of these samples will help to understand where the materials were de...


Community-based long-term monitoring of the Peel River near Fort McPherson
Principal Investigator: Moore, Jonathan
Licenced Year(s): 2018 2017
Summary: The objective of this research is to establish a community-based monitoring program in the Peel River watershed, based in Fort McPherson. Previous research has shown that multiple whitefish ecotypes (non-anadromous, semi-anadromous and anadromous, utilize the Peel River as spawning habitat, but it is unclear how much each ecotype contributes to harvester catches. As different ecotypes occupy d...


Metallogenic Investigation of the East Arm
Principal Investigator: Cairns, Scott
Licenced Year(s): 2018 2017
Summary: Recent evolving thoughts on the geological history of the East Arm of Great Slave Lake require the area to be re-evaluated with respect to its structural and metamorphic history as well as to explain its metal endowment. This study seeks to evaluate the structural and metamorphic history of the area, and its potential to host economic mineralization. Field investigations will examine exposures ...


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...


Radar Remote Sensing of Snow
Principal Investigator: Kelly, Richard
Licenced Year(s): 2018 2017
Summary: The primary objectives of this study are to: 1) understand and explain the role of snow microstructure in terms of the radar backscatter and phase response in this environment 2) to evaluate the efficacy of differential synthetic aperture radar (dInSAR) for snow accumulation estimates at C-band, and 3) to evaluate the optimal approach to estimating snow water equivalent using radar from this site....
