Summary: Here is the project summary from the (U.S.) National Science Foundation proposal that led to this expedition: The research team propose a three-year project to investigate the origin of the Younger Dryas cooling that began about 13,000 years ago. For decades this cold event has been associated with sea ice in the Arctic and North Atlantic Oceans, and the storage and release of fresh water from ...

Summary: 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...

Summary: 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...

Summary: 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...

Summary: The aims of the various components of this project are to develop a hydraulic model for the Mackenzie Delta by observation of ice jams for calibration of the model, assessing ice cover and breakup patterns, linking an ice-ocean-atmosphere model of storm surges to the hydraulic model, measuring water stored in off-channel areas, improving information on lake-flooding for off-channel areas, quantify...

Summary: The objective of this study is to determine the water cycle processes acting in lakes and streams that affect the streamflow of Baker Creek and similar streams, and to understand how processes acting over smaller areas influence those that are predominant over larger areas. Existing infrastructure, including 2 climate towers and a hydrometric gauge, will be built upon. Snow surveys will be c...

Licensed Year(s): 2007
Summary: The goals of this study are: to develop an understanding of water and ice behaviour in sites on the Mackenzie and Great Bear rivers; to obtain knowledge of water speed, depth, current profile, frazil ice and how deep ice may reach into the rivers during the Spring break up; to use this information to determine the feasibility of using Ducted Venturi and Gorlov Helical Turbines (DV-GHT) to harness ...

Summary: The objectives of this research are to document the glaciers in the Ragged Range, how they have changed in the past and what their role is presently in providing meltwater for the upper reaches of the South Nahanni River and the Flat River. Glaciers nourish streams and groundwater when other sources are absent or in decline (e.g., snowmelt, precipitation). They are most important late in the...

Principal Investigator: Smith, Roger F.
Licensed Year(s): 1994
Summary: The researchers will conduct a variety of research activities at the study site. Projects include surveys of insects and plants, monitoring glacier movements, collecting data about the area's rocks and soils, assessing changes in the area's climate and environment (using fossils of microscopic marine organisms, chironomids, as indicators), and investigating radio-wave propagation....

Principal Investigator: Hicock, Stephen R.
Licensed Year(s): 1992
Summary: The research will involve the study of the interplay (past and present) between glaciers, permafrost, meltwater and seawater on the southwestern side of the Bylot Island ice cap....
