Greenhouse Gas Exchange in the Outer Mackenzie Delta
Principal Investigator: Skeeter, Wesley R
Licenced Year(s): 2017
Summary: The objective of this campaign will be to measure the emission/uptake of methane and carbon dioxide at Fish Island in the outer Mackenzie Delta over a full growing season. This data will be used to determine the carbon balance of the island, and estimate the carbon balance of the land surfaces in the outer Mackenzie Delta. Additionally, the research team will investigate factors influencing the ex...


Drivers and constraints of ecological change in the western Arctic
Principal Investigator: Lantz, Trevor C.
Licenced Year(s): 2017
Summary: The objectives of this project are to: 1) use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, lake drainage / expansion, etc.) in the NWT; and, 2) use field sampling and monitoring to determine the causes and impacts of regional changes in vegetation, and permafrost. To quantify land...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and, 3) to assess the physical and chemical characteristics of permafrost. To achieve the objectives the r...


Beaufort Sea Coastal Geoscience Research
Principal Investigator: Whalen, Dustin JR
Licenced Year(s): 2016 2015 2014 2013 2012
Summary: The primary objective of this research continues to be driven towards the safe and sustainable industrial and community development of the Beaufort Sea coastal nearshore region. The research provides the means to improve knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and reduce the impacts of natural...


Contemporary Dynamics of Forest-Tundra Ecotones in Central NWT
Principal Investigator: Danby, Ryan K
Licenced Year(s): 2016
Summary: Objectives of this research project are to: 1) analyze Landsat satellite images to understand regional vegetation change over the past 30 years; 2) determine the timing of tree establishment as well as the climate influence on tree growth across the forest tundra transition zone over the past 300 years; and, 3. measure spruce seedling growth across the forest-tundra ecotone in relation to varia...


Landscape scale flooding in the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licenced Year(s): 2014 2013 2012 2011 2010
Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...


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 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 ...
