Summary: This licence has been issued for the scientific research application No.5155. The objective of this project is to complete on ice snow depth, ice thickness and composition survey along with collection under ice core water quality information. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to pene...

Summary: This licence has been issued for the scientific research application No.5130. The first objective of this research is to understand how ground temperatures vary within the highway embankment between the border on the Dempster Highway and the north end of the Inuvik to Tuktoyaktuk Highway. The road surface varies little between these points and it is cleared in winter, so conditions should be un...

Summary: Fundamental sea ice properties such as volume and surface characteristics change significantly within and between years. Arctic sea ice extent and thickness have undergone dramatic changes in the past decades. The strength of ice-albedo feedback mechanism depends on area-averaged ice concentration, snow and ice thickness and in summer significantly on melt pond fraction. The sea ice retreat in ...

Principal Investigator: Kasook, Davonna C
Licensed Year(s): 2018 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will investigate the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical ...

Summary: The observational platform will be a single aircraft, the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft. Objectives of this project are to: 1. determine the actual state of the sea ice thickness distribution in the western Arctic and what are trends of the Sea Ice thinning; 2. characterize the actual sea ice thickness distribution and identify trends in the sea ice thickne...

Summary: The proposed European Space Agency Earth Explorer 7 CoReH20 satellite mission has the primary objective of retrieving snow water equivalent (SWE) over land at a high spatial resolution (200-500 metres) from X- and Ku-band Synthetic Aperture Radar measurements. This would make available high resolution, satellite derived SWE, for monitoring and modeling applications. To-date, airborne measurements ...

Summary: 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 ...

Summary: The principal objective of this research is to determine how permafrost conditions in the western Arctic will respond to climate change. Additional objectives are to determine how lake temperatures respond to climate change, and how snow depths affect ground temperatures. How permafrost responds to climate change will affect how the ground supports development projects in the future. Data is be...

Licensed Year(s): 1994 1993 1993 1992 1992 1991
Summary: The researcher will conduct a geotechnical survey of the area. Components of this survey will include shallow geological drilling, geophysical downholde logging, geophysical electrical sounding and a snow depth transect. A crew will transverse the area by foot and skidoo....

Summary: Ice gauges are installed on river ice once the ice is strong enough to support researchers (20 gauges in the Mackenzie Delta and 15 gauges on Hay River). The gauges are read every 10 days to obtain total ice thickness, white ice thickness and snow depth. From these data, the rates of ice growth and decay can be calculated, and the approximate date of maximum ice thickness can also be determined....
