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 the research team will obtain Landsat satellite images that will provide reflectance measurements covering a 1...

Résumé:
The objective is to develop a current and complete development footprint for a designated area of the Central Mackenzie Valley, Northwest Territories (NWT), that includes specified disturbance attributes; captures an estimate of current recovery state; and, provides data to predict disturbance recovery trajectories and project footprint change over time.
Anthropogenic disturbance features will ...

Résumé:
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...

Résumé:
The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study:
1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)?
2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay?
3) How much of ...

2013 Résumé:
Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...

Résumé:
This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...

Résumé:
The objective of the project is to identify the fish species present, and to gather population data on surveyed species, in waterbodies in the area of Husky’s proposed exploration activity.
Four streams and four to seven small lakes are proposed to be assessed. The Cumulative Impact Monitoring Program recommended selecting 2-4 streams appropriate for collection of baseline information that can...

2012 Résumé:
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 stream...

Résumé:
The Permanent Monitoring Plots will provide experimental data on forest growth and progression, cumulative impact monitoring, and will provide data for territorial and national reporting requirements.
Most plots will be accessed only by helicopter. At each site, a 400 square metre plot (11.28 m radius) will be established with rebar as a centre post. All trees, shrubs and other vegetation will...

Résumé:
This project is the initiation of traditional knowledge (TK) studies in the Kakisa area, discussions for which were initiated in 2003 as part of the baseline studies and assessment for the Mackenzie Gas Project. The study will involve gathering and reviewing documented and new knowledge related to climate, soil, water, vegetation, wildlife, birds, fish, historical/cultural/spiritual sites, human ...
