A Program to Evaluate Changing Northern Lake Ice Regimes
chercheur principal: Dibike, Yonas
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016
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...


Permafrost conditions along the Dempster-ITH corridor
chercheur principal: Stockton, Emma
Année(s) de permis: 2022 2021 2020
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...


Ice Bird 2019
chercheur principal: Hendricks, Stefan
Année(s) de permis: 2019
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 ...


Comparing the snow depths and densities of different habitats in the Beaufort Delta region
chercheur principal: Kasook, Davonna C
Année(s) de permis: 2018 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 ...


Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP)
chercheur principal: Herber, Andreas
Année(s) de permis: 2017
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...


Thermal State of Permafrost
chercheur principal: Siegfried, Dian
Année(s) de permis: 2016 2013 2010
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...


Airborne SAR and passive microwave measurements over snow covered tundra for CoReH20 retrieval validation and land surface model testing
chercheur principal: Derksen, Chris
Année(s) de permis: 2013 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 ...


An Integrated Sea Ice Project for BREA: Detection, Motion, and RADARSAT Mapping of Extreme Ice Features in the Southern Beaufort Sea
chercheur principal: Barber, David G.
Année(s) de permis: 2013 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 ...


Controls on carbon and nutrient cycling in arctic tundra
chercheur principal: Grogan, Paul
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008
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...


Permafrost and climate change, western Arctic Canada
chercheur principal: Burn, Chris R
Année(s) de permis: 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
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...
