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...

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...

Correlation of snow density and depths of urban disturbed and undisturbed areas in Inuvik
Principal Investigator: Jacobson, Ashley A
Licenced Year(s): 2018
Summary: The objective of this project is to measure the depths and density of snow in the Inuvik area. The Principal Investigator (PI) will compare and contrast important trends, snow types, snow forms, water equivalency and the quality of the cover. The PI will be using a snow mobile and walking to the sites. Measurements will be taken with a snow core barrel. The PI will stick the core barrel in the ...

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....

De Beers - Gahcho Kué Environmental Monitoring Program
Principal Investigator: Kramers, Patrick
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective of the proposed studies is to obtain information on the environment once Project activities commence to determine potential project effects. The proposed studies will include the collection of air quality, geochemistry, hydrology, water and sediment quality, and fish and aquatic resources, dustfall, vegetation and soil information. The studies (further defined below) are designed...

A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
Principal Investigator: Palmer, Mike
Licenced Year(s): 2018 2017
Summary: The overarching objectives of this research are two-fold: 1) to investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) to investigate the toxicological consequences of...

The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. We are interested in how climate change is impacting Arctic rivers. The research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to det...

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 (...

Remote sensing of Arctic-Boreal surface water
Principal Investigator: Smith, Laurence C.
Licenced Year(s): 2017
Summary: The goal of this project is to measure variations in water surface elevation, inundation extent, permafrost presence/absence, active layer thickness, soil moisture and related variables for lakes, wetlands and rivers in four primary study areas within the Northwest Territories (NWT). Using ground measurements combined with maps of water surface elevation produced by the Air Surface Water and Ocean...
