Summary: The first objective is to compare present ground ice conditions to those recorded thirty years ago, and from this, obtain an estimate of the rate of ground ice accumulation over the past three decades. This is possible as the exact locations cored in 1979 and 1980 are marked, and new cores can be taken adjacent to these. The second objective is to compare ice conditions from sites within the basin...

Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application no. 956. The primary objective of this study is to field test and assess the utility of an electromagnetic (EM) geophysical technique called magnetotellurics (MT), as an inexpensive method for mapping spatial variations and changes within permafrost in the Mackenzie Delta area. Due to the large change in soil electrical resist...

Summary: This licence was issued for the application no. 822. The objective of this research is to determine how the environment of Banks Island has evolved during the past several hundred thousand years to present, especially whether Banks Island served as a biological refugia during previous glaciations. The researchers aim to understand and reconstruct the extent and dynamics of past glaciers, past c...

Principal Investigator: Lesack, Lance
Licensed Year(s): 2008 2007
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 objectives of this ongoing research project are: (a) to monitor climate change by measuring the changing volume of the ice cap and maintaining an automatic weather station, and (b) to monitor air and snow pollution by sampling snow and sending it to be analyzed. Based out of the Polar Continental Shelf Project in Resolute Bay, NU, two personnel will fly by Twin Otter to the ice cap, and liv...

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...

Principal Investigator: Dallimore, Scott R

Summary: This licence was issued for the scientific research licence application number 757. This research will concentrate on characterization of 3 observed gas seeps, identification of additional seeps in the region, and characterization of permafrost conditions, as thinning permafrost and the development of taliks is a hypothesized mechanism for the development of gas discharge pathways. Water and...

Principal Investigator: Katz, Sharon
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 ...

Principal Investigator: Demuth, Michael N
Licensed Year(s): 2007
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: Moorman, Brian J
Licensed Year(s): 2007
Summary: Ice patches in the Mackenzie Mountains are areas of permanent ice that last through the summer months and often contain frozen caribou remains (mostly dung) and archaeological artifacts such as hunting weapons and tools. As the climate warms, these ice patches are beginning to melt, and there is a risk of losing the biological and archaeological information they contain. Using a technique known a...
