NWT ice patch study

Thomas D. Andrews, Brian Moorman, Glen MacKay & Leon Andrew
Twenty-eight alpine ice patches were identified using a combination of remote sensing techniques, archaeological site survey methods, and traditional knowledge. These alpine patches are similar in that they are all used extensively by caribou in summer and are accessible to human hunters. Biological specimens were collected from all 28 sites using ice coring technology and surface collection and include faunal remains (mostly bones) and fecal matter. The osteological remains were used, along with modern samples,...

The impacts of oil and gas activity on peoples in the Arctic using a multiple securities perspective (GAPS)

Dawn Bazely, Annette Dubreuil, Gabrielle Slowey, Gunhild Hoogensen & Julia Blythe Christensen Kereliuk
Background: Since the early 1970s oil and gas development has come to dominate the industrial sector in the Arctic. At the same time, the region is experiencing climate change with increasing intensity. The pace of resource development has accelerated significantly in recent years as the price of oil and gas has risen, motivating industry to travel further north to extract fossil fuels for global consumption. Increasing pressure from various governments¿Russian, Norwegian, Canadian and American¿requires the...

Climate change Impacts on Canadian Arctic Tundra ecosystems (CICAT): Interdisciplinary and multi-scale assessments

Greg Henry, Alain Cuerrier, Angela Bedard-Haughn, , Keith Egger, Michelle Garneau, Richard Farrell, Robert Grant &
At some CICAT research sites, we established experiments that simulate warming and changes in snow depth and measured the responses. Warming causes earlier flowering, greater growth and an increase in the cover of shrubs and grasses. We also examined the changes in vegetation across large areas using satellite data, and our results have shown a decrease in important winter range of the Bathurst caribou herd during the past twenty years due mainly to increases in...

Monitoring of the relative abundance of tundra bird and mammal species encountered daily on Bylot Island, Nunavut

Gilles Gauthier, Marie-Christine Cadieux &
The relative abundance of species is recorded as the number of individuals seen per hour spent in the field per observer. Each observer records the animal species encountered in the field and the number of individuals observed daily. To correct for any potential biases, the activities and the mode of transportation of observers is also taken into account. We also monitor the nests of bird species that are not part of our long-term monitoring and...

Long-term monitoring of the cycles and success of breeding activity of Canada Geese on Akimiski Island, Nunavut

Kenneth F. Abraham
We have monitored the nesting activity of Canada Geese since 1993. We have monitored productivity measured as goslings per adult, per breeding female, since 1983. For the goose nesting ecology work, we find nests through systematic searches of up to 7 coastal segments on the North shore of Akimiski Island, and follow them through to the end of hatch, including a program of web-tagging individual goslings at hatch. Nests of snow geese were monitored similarly...
