Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
Principal Investigator: Hille, Erika C
Licenced Year(s): 2018
Summary: The objectives of this project are to: 1) create a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk; 2) develop detailed water, vegetation, and ground temperature maps of the study sites using drones; 3) examine the effects of thaw slumping on the water quality of landscape-level runoff to the Beaufort Sea; 4) examine the effects of coastal erosion ...


The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2018 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of carbon from land to water, and the effects of this transport on stream communities and the global carbon cycle. This summer, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experi...


Kennady North Diamond Project
Principal Investigator: Panayi, Damian
Licenced Year(s): 2018 2017 2016
Summary: The objective of this project is to document existing environmental conditions in the aquatic environment. The hydrology program includes the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor lake levels through the open-water season. Hydrology studies will be initiated during the spring freshet. Equ...


Impacts of permafrost thaw on hydrology and water resources
Principal Investigator: Quinton, William L.
Licenced Year(s): 2018 2017
Summary: Understanding the ecology and hydrology of ecosystems with thawing permafrost is a major challenge. To meet this, the research team will develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bogs, fens, peat plateaus) needed to develop new science-based tools to predict the future supply for the next 50 years. The specific scientific objectives are: 1) to develop fundamental kno...


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): 2018 2017
Summary: The goal of this research is to characterize the hydrology of an alpine valley’s landscape types (LTs) and how they affect storage and runoff responses to precipitation through the following four research objectives: 1) A physical description of LTs composing an alpine study catchment that are expected to exhibit distinct hydrological responses to precipitation inputs; 2) A physical descriptio...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2018 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; 3) assess the physical and chemical characteristics of permafrost; and, 4) to monitor the thermal evolution of...


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...


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....
