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...

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...

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...

As the demand for oil and gas resources increases pipeline construction pushes further into the Arctic and sub-Arctic regions. Consequently, these buried pipelines suffer much harsh environmental and complex loading conditions. Moreover, to increase the transporting efficiency, larger size pipes...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....

IMPACTS OF DISTANCE TO PIPELINE DISTURBANCE ON MIXED GRASS PRAIRIE AND HALIMOLOBOS VIRGATA (NUTT.) O.E. SCHULZ (SLENDER MOUSE EAR CRESS)
DownloadSpring 2014
Halimolobos virgata (slender mouse ear cress) is an at risk plant species in the Dry Mixed Grass Subregion of Southern Alberta. Little is known about effects of disturbances such as pipelines on Halimolobos virgata and its habitat. Environment Canada recommends a non species specific set back of...

River runoff plays a very important role in the Arctic Ocean. The Arctic Ocean accounts for around 1% of the total world ocean volume, but receives around 11% of the worlds river runoff. In addition, the Arctic Ocean is a β ocean, where stratification is primarily determined by salinity as...
