202120202019201820172016 Résumé:
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...

20212020 Résumé:
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...

Résumé:
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 ...

2017 Résumé:
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 ...

Résumé:
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...

20132010 Résumé:
The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. At these sites the research team have lost remote (satellite) communication and need to make repairs to continue receiving data.
The research team are currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and...

2012 Résumé:
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 ...

2012 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 ...

201020092008 Résumé:
The goal of this research over the next five years is to substantially advance our understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the researchers will focus on the impacts on vegetation due to warmer summer temper...

20052004200320022001200019991998 Résumé:
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...
