Summary:
The objective of this work is to investigate the impact of permafrost disturbance on water quality by examining varying sizes of watersheds with different magnitudes of disturbance. The impact of disturbance on water quality will be examined in a number of different research questions: 1) does watershed size impact downstream water quality where there is the same magnitude of disturbance; 2) is wa...

Summary:
Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

The objective of this research project is to document the extent of ecological change in impacted stream basins draining the eastern slope of the Richardson Mountains and to determine the mechanisms of slump initiation and stabilization. This study will focus on the Stoney Creek catchment, which runs parallel to the Dempster Highway and empties into the Peel River at Fort McPherson, NT. The catchm...

Summary:
This project has three main objectives:
Objective 1: To use satellite imagery (Landsat, QuickBird, InSAR, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, etc.) in the northern Mackenzie Basin.
To quantify landscape disturbances and vegetation regeneration patterns since 1985 Landsat satellite images will be obtained, that will provide refle...

The objectives of this research are: 1) to determine the status of permafrost landforms. Since 1990, automated microclimate stations powered by solar cells have been operated in the study area. One station is located at each of five permafrost landforms called palsas (low peat covered mounds with permafrost cores). The stations keep a record of permafrost and near-surface temperatures. Depth of...

Summary:
This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to : 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of strea...

The objectives of this research are:
• To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Mackenzie Valley.
• Monitor ground temperature and active layer to detect changes in permafrost conditions resulting from surface disturbance or climate change a...
