Summary: This licence has been issued for the scientific research application No. 5791. The objectives of this study are to (1) evaluate the geologic setting including geochemistry, and dating of sediments to establish a regional history of the area. (2) investigate the geologic setting of multiple buried, massive ice bodies. And (3) develop a geologic and hazards map along the ITH, highlighting feature...

Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5723. To measure ice snow depth, ice thickness and composition survey on Noell Lake in the spring. 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 penetrate the ice cover and evaluate if white ice is present. If present ...

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...

Licensed Year(s): 2019
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 ...

Licensed Year(s): 2015 2014
Summary: The objective of this study is to measure ice depth and river flow during the winter months. Spring break up will provide crucial details as to its impact on the potential use of hydrokinetic turbines (ie. determining if there is scouring etc.). A hole will be drilled in the ice and a 200 pound sonar device will be placed on the bottom of the river. It will be anchored to the river bottom until...

Licensed Year(s): 2013 2012
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 ...

Principal Investigator: Walker, Anne E
Licensed Year(s): 2008
Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...

Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005 2004
Summary: The objective of this study is to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta; the hydroclimatic conditions controlling the occurrence of ice jams and associated floods; to develop a hydraulic model of ice jamming for the Mackenzie Delta, and to investigate the importance of deep scour holes in the Mackenzie River. Quarterly field trips are scheduled for mid-Ma...

Licensed Year(s): 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
Summary: The researchers hope to measure ground temperatures to find out how they are changing as a result of climate change. They will try to find out how the thickness of the snow cover affects the amount of ground warming that has occurred over the past 35 years. The researchers will study the cracking of ice wedges to find out if they are cracking less now than they did in the 1970s and 1980s. The...

Principal Investigator: Povey, Andrew
Licensed Year(s): 2005 2004 2003
Summary: The researchers did a number of baseline studies during 2001 through 2004 as part of the Mackenzie Gas Project. These studies are continuing in 2005. Local knowledge and technical/scientific research is being used to design plans, assess impacts, and develop environmental protection plans. The aquatics field crews will consist of two Mackenzie Project Environment Group researchers and a local as...
