“Environmental Studies across Treeline (ESAT) in the Mackenzie Delta region” is a northern based collaborative program with an objective to enhance the understanding of environmental conditions in the Mackenzie Delta region through scientific studies and monitoring. Specific studies include: 1) monitoring permafrost conditions in the Mackenzie Delta region; 2) examining freeze-back of the active l...

Résumé:
Climate change and sea ice change affects all who live in the north. The aim of this project is to improve understanding of the physical processes in Arctic clouds and their contribution to the current changes in the polar environment, and thereby reducing uncertainties in regional and global model simulations important for future weather and climate prediction.
These research activities combin...

Résumé:
The objective of this study is to provide information on the thickness distribution, movement, and characteristics of different types of sea ice within the Beaufort Sea Region. The focus will be on hummocked multi-year sea ice referred to as Extreme Ice Features (EIFs). These EIFs are poorly understood, and would be the most hazardous to any engineered structure in the southern Beaufort Sea (such ...

The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team also intends to investigate the ice content of the ground and how this may affect terrain stability. The research team wishes to study changes in ground temperature at various locations in the western Arctic, ranging from Her...

20102009 Résumé:
The project investigates and develops the potential of Canada’s RADARSAT satellites as a tool for the collection of information on (change in) river ice conditions and, during spring breakup, flood conditions in the Mackenzie Delta. During the upcoming year (2012), the research will focus on the application of RADARSAT images in support of the mapping of winter ice cover characteristics, e.g. ice ...

2010200920082007200620052004 Résumé:
This research project has two primary scientific goals which include:
1) Relating ground truthed snowpack data to passive microwave data obtained from satellites through the winter months. This will assist in formulating a empirical relationship between the two datasets which is necessary to improve satellite monitoring of snow water equivalent.
2) Determining the relative importance of snowmel...

201120102009200820072006 Résumé:
The objectives of this project are: (1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions, and (2) to develop an improved understanding of, and ability to predict, water levels in the lakes and channels of the Mackenzie Delta. These will allow a better understanding of the impact of climate change and/or natu...

The long-term goal of this research project is to develop a suite of models for predicting the response of discontinuous permafrost in the Hay River Lowland to climate warming and human disturbance from oil and gas exploration, and the consequent change in landcover and river flow regime. This will be achieved by meeting the following short-term objectives: 1) map the spatial distribution of perma...

Résumé:
The objectives of this project are to define the impact of snow depth, surface vegetation, and soil characteristics on spatial and temporal variations in active-layer freeze-back in the low arctic tundra east of the Mackenzie Delta. The duration of freeze back will be determined from the ground temperatures measured at the top of permafrost. This temperature only declines at the site when the ac...

Résumé:
The objective of this research is to record permafrost temperatures.
The investigator has permafrost stations already in place that have been collecting data for over 4 years and will connect to these loggers to download data. Data acquisition equipment will be downloaded and upgraded.
The researcher will report on finding to the Aurora Research Institute.
The fieldwork for this study wi...
