Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

Ecohydraulics of Nature-Like Fishways and Applications in Arctic Aquatic Ecosystem Connectivity
DownloadFall 2015
Northern Canada is currently undergoing rapid mineral extraction development. As part of this development there is a need to perform fish habitat compensation projects and build effective fish passage facilities. There is currently limited information available on the hydraulics of nature-like...

Effects of retrogressive thaw slumping on particulate organic carbon dynamics in the Northwest Territories, Canada
DownloadSpring 2022
Climate change is increasing the frequency and intensity of thermokarst and accelerating the delivery of terrestrial organic material from previously sequestered sources to aquatic systems, where it is subject to further biochemical alteration. Rapid climate change in the glacially conditioned...

Spring 2012
Automatic weather monitoring stations deployed in arctic regions are usually installed in hard to reach locations. Most of the time they run unsupervised and they face severe environmental conditions: very low temperatures, ice riming, etc. It is usual practice to use a local energy source to...

Evaluating Fish Habitat Compensation in the Canadian Arctic: Stream Habitat Attributes and Macroinvertebrate Assemblages
DownloadFall 2014
Resource development is expanding in Canada, particularly in the Arctic. In Canada, damage to stream ecosystems as a result of development requires habitat restoration or compensation measures. A compensation project, focused on improving ecosystem connectivity and aquatic habitat for fish within...

Evaluating recent advances in active microwave remote sensing for Arctic sea ice monitoring
DownloadFall 2018
The objective of this research was to evaluate recent advances in active microwave remote sensing technologies in order to further refine the optimal radar parameters for sea ice monitoring in support of marine operations and climate research. To achieve this objective, data from recent active...

Resource development can lead to the harmful alteration, disruption, or destruction of fish habitat. During Diavik Diamond Mine, Inc.’s (DDMI) development of its facilities at Lac de Gras (LDG), NWT, DDMI destroyed two small headwater lakes and associated streams. To help offset this loss, DDMI...

Fluvial inorganic carbon cycling across divergently evolving permafrost landscapes (Yukon and Northwest Territories, Canada)
DownloadFall 2019
Across the circumpolar north, rapid warming and intensifying hydrologic cycles are accelerating permafrost thaw and strengthening land-freshwater linkages. Among the most significant implications of this change is the mobilization of large amounts of previously sequestered organic and inorganic...

Fall 2015
Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...
