Summary: The objective of this project is to conduct snow surveys at selected sites in the Mackenzie Delta, related to permafrost studies. Snow surveys will be carried out at three selected sites in the Delta during early April. These are Circumpolar Active Layer Monitoring Program sites. There is a grid marked on these locations, where the researchers will be measuring the snow pack and snow density. M...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: The purpose of this project is to complete the determination of the variation and distribution of near-surface ground ice at Kendall Island Bird Sanctuary (KIBS) begun in 2006. The aim is to collect ground ice samples along previously established vegetation and snow courses within distinct terrain units and transition zones, and to determine the relations between ground ice configuration and the s...

Summary: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...

Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Summary: This research forms part of an aerial reconnaissance program to observe the characteristic break-up patterns at selected watercourse crossings along the proposed pipeline right-of-way from the Deh Cho region in the south to the Inuvialuit Settlement Regi...

Principal Investigator: Riseborough, Dan
Licensed Year(s): 2001 2000
Summary: This study will attempt to understand and predict how cold the ground surface gets in the winter under snow. Transportation to the site will be by helicopter and accommodation at the site will be in tents or at an existing cabin. Travel from camps to sample sites will be by foot. Electronic data recorders were installed in August 2000 to record air, ground and surface temperature through the wi...

Principal Investigator: Yamashita, Akira
Licensed Year(s): 1995
Summary: The researchers will observe crystal formation from ice fog through the collection of samples for microscopic observation and through the taking of photographs/video of optical phenomena produced by floating ice crystals. Particle counting and cloud condensation nucleus counting at the observation site will also be done....

Summary: The researchers will continue their study, initiated in 1990, on the geological and hydrological processes which contribute to valley formation in the subarctic and arctic. Data will be collected on various aspects of water runoff and sediment content. This data, along with long-term environmental data collected by Environment Canada, will contribute to our knowledge about valley formation....

Summary: As part of a long-term study, this research will examine the important role that snow plays in northern ecosystems. Snow accounts for a large portion of yearly precipitation: when it melts, snow is a significant source of freshwater for refilling lakes and ponds, and for plant growth. This study will examine the role that snow plays in controlling streamflow and movement of solutes, nutrients an...
