Determination of near-surface permafrost extent in the Mackenzie Delta
Principal Investigator: Nguyen, Thai-Nguyen
Licenced Year(s): 2006 2005
Summary: The climate and numerous field reports indicate that permafrost should be continuous in the Mackenzie Delta. However, the most recent permafrost map in the Atlas of Canada classifies the delta as having discontinuous permafrost. Yet, no extensive fieldwork covering the entire delta has ever been realized. Unfrozen conditions beneath the ground, near shifting channels, have been recognized by vario...

Sekwi Mountain Project
Principal Investigator: Martel, Edith
Licenced Year(s): 2007 2006
Summary: The Sekwi Mapping Project is aimed at defining the structural, stratigraphic, metallogenic and geochronological characteristics of the bedrock of a segment of the Mackenzie Mountains. The project will also involve assessment of the mineral, diamond and hydrocarbon potential of the area. This information will provide an updated geological database that will include a GIS-based compilation of bedroc...

Massive Ice Study in Granular Deposits
Principal Investigator: Pollard, Wayne H
Licenced Year(s): 2006 2005 2004 2003
Summary: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...

Monitoring Permafrost Deformation in the Mackenzie Delta
Principal Investigator: Tait, Matthew P.
Licenced Year(s): 2005 2004
Summary: The objective of this research is to establish the abilities of the radar method to detect vertical land deformation compared to traditional methods. Researchers will measure the topography of a target area in both June and August. During those months, researchers will also capture radar images of the same area. The topographical measurements will be compared to the radar images to determine the e...

Twin Otter Aerial Surveys of Sea Ice During Spring Melt
Principal Investigator: Barber, David G.
Licenced Year(s): 2004 2003
Summary: The objective of the research is to produce estimations of the reduction in sea ice in the ISR. Eight aerial surveys are planned for approximately May 1, 14, 31, June 14, 28, July 5 and 15 (weather and aircraft availability dependent). Each survey will b...

Coastal Hazards, Relative Sea-level Change, and Climate Impacts on Northern Coasts and Seaways
Principal Investigator: Forbes, Donald L
Licenced Year(s): 2006 2005 2004 2003 2002 2001
Summary: The western Canadian Arctic coast is one of the most rapidly changing coastlines in the world and among the most vulnerable to climate change. The causes of this vulnerability have been studied over the past decade. This project involves monitoring coast...

FIRE III: An Arctic Cloud Study
Principal Investigator: Isaac, George
Licenced Year(s): 1998
Summary: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

An algorithm for estimating aerial snow water equivalent in the Northwest Territories using passive microwave data
Principal Investigator: Gan, Thian Yew
Licenced Year(s): 1994 1993
Summary: Given the vast size of the N.W.T., it is very difficult to accurately measure the amount of water that is made available from snow (called snow water equivalents or SWE). A variety of agencies have collected data from climate stations and satellites and this data can be used to estimate SWE. This study will involve taking measurements of snow on the ground and comparing these measurements to th...

A Seasonal Sea Ice Monitoring Site (SIMS)
Principal Investigator: Barber, David G.
Licenced Year(s): 1995 1994 1993 1992 1991 1990
Summary: The primary objective of the research is to characterize the physical processes of the ice/ocean/atmosphere interface and to develop the capability to measure the pertinent variables using remote sensing data. The operational monitoring which can be provided by satellite remote sensing, is a necessary prerequisite to understanding the impacts of CO2 induced warming of the ice covered regi...

An Evaluation of Satellite Data to Detect and Monitor Vegetation Responses to Climate Warming at Treeline
Principal Investigator: Pearce, Cheryl M.
Licenced Year(s): 1993 1992 1991 1990
Summary: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...
