Principal Investigator: Kelly, Richard
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5877. The main objectives are: 1. to fly a novel Ku- and L-band synthetic aperture radar (SAR) system over snow covered tundra land, lakes and sea ice in winter to obtain unique radar observations of these environments; 2. to use collected field measurements acquired by J. Thériault's project (license #5743) at Trail Valle...

Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5335. This proposed research is directed at understanding the impact of current/future climate warming on subarctic lake ecosystems. The aim is to explore the relationship of seasonal lake ice growth/ablation and water quality across a wide range of lake characteristics (size, volume, productivity, catchment characteristics...

Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5184. This project aims to reconstruct trends in ice phenology using remotely-sensed and ground-based observations and collective memories of land-based and in-lake changes by communities living along the shoreline of Great Bear Lake (GBL) to characterize the inter-annual variability of ice formation in the lake and determi...

Principal Investigator: Stockton, Emma
Licensed Year(s): 2022 2021 2020
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...

Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4648. This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch June 2019) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the ...

Principal Investigator: van der Sanden, Josephus J
Licensed Year(s): 2019
Summary: This project aims to undertake fieldwork in the context of the PermASAR winter campaign. The data collected will support the evaluation and development of radar satellite Earth observation (EO) technology for application to the mapping of river and lake ice processes and properties. The research team expect the fieldwork to take place over a period of two to three weeks in the months of Februar...

Licensed Year(s): 2017 2012 2010 2009
Summary: This project aims to evaluate and develop the utility of Canada’s future RADARSAT Constellation Mission (RCM) (launch 2018) for the monitoring of lake ice breakup and freeze-up. RCM-type radar images will be simulated using data from Canada’s current radar satellite – that is - RADARSAT-2. Validation data in the form of oblique aerial photographs are required to assess the accuracy of the image pr...

Principal Investigator: Wrona, Frederick J
Licensed Year(s): 2015 2014 2013 2012 2011 2010 2009
Summary: The overall objective of this research component is to improve knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The methodology described here pertains to research activities involving the automated ice buoy and instrumented subsurface mooring system for continuous monitoring o...

Licensed Year(s): 2011 2010 2009
Summary: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...

Principal Investigator: English, Michael C
Licensed Year(s): 2012 2010 2009 2008 2007 2006 2005 2004
Summary: This project would improve the national snow water equivalent (SWE) monitoring capabilities by acquiring the necessary data to estimate SWE in the snow covered tundra environment. Transportation for local surveys will be by snowmobiles. Regional surveys...
