Influence of the Arctic on Mid-latitude Weather and Climate: Observation of Precipitation Particles at Inuvik.
chercheur principal:
Année(s) de permis: 1995
Résumé: 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....

Current contaminant deposition measurements in precipitation throughout the NWT
chercheur principal:
Année(s) de permis: 1993
Résumé: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...

Spatial variation in the isotopic composition of snowpack in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This on-going research involves the assessment of isotopes in snowpack each winter. Collection of snow and ice at various sites along winter roads in the N.W.T. provides information about the composition of isotopes within a region. Isotopic composition of snow and ice taken from ice cores in Greenland and Antarctica have been able to provide information about past climates....

Snow Melt Runoff in High Latitude Permafrost Basins
chercheur principal:
Année(s) de permis: 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: The research project will include measuring the amount of snow on the ground, changes in snow properties during spring melt, weather conditions and runoff in nearby rivers. The purpose of the project is to improve ability to predict smowmelt runoff to rivers and lakes in Northern Canada....
