Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5987. The aim of the citizen science project UndercoverEisAgenten is to study permafrost changes in the Arctic to raise awareness of these environmental changes and strengthen the data basis for science. Students from Moose Kerr school in Aklavik will design their own permafrost change related research questions and work w...

Principal Investigator: Bilodeau, Jean-Pascal
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5914. The main objective is to develop a practical method for the mechanical and thermal design of embankments built on permafrost based on the properties of the active layer and of the permafrost, as well as the loading conditions. An existing thin section of the highway embankment built on permafrost has been instrume...

Summary: This licence has been issued for the scientific research application No. 5833. This research aims to describe permafrost conditions and assess environmental risk at several drilling waste sumps in the Mackenzie Delta region, NWT. The objectives of this project are: 1) Assess the vulnerability of drilling mud sumps in the Mackenzie Delta region under varying site conditions and different clim...

Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5688. The objectives of this research project are to: 1) fly multiple lines of airborne electromagnetic (AEM) geophysical data (between 4 and 6 parallel lines ~100 m apart) between Inuvik and Tuktoyaktuk, beginning and ending just outside the communities; 2) using the geophysical and geological data, produce maps of the In...

Principal Investigator: Dallimore, Scott R
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5059. We wish to study the rate of degradation of nearshore permafrost with interests in the environmental and geohazard implications. The coast of the Beaufort Sea has been experiencing the effects of climate change over the past thirty years with atmospheric warming 2 to 3 times the global average and dramatic changes...

Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...

Principal Investigator: Wrona, Frederick J
Licensed Year(s): 2010
Summary: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...

Licensed Year(s): 2011 2009 2007
Summary: This licence is being issued for the scientific research application no. 955. The objective of this research is to collect sediment cores from the Mackenzie River Delta in order to study how the river has behaved in the past, and see if the researchers can detect recent changes due to thawing permafrost. More specifically, the goal is to determine whether the researchers can reconstruct past c...

Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: The goal of this research is to understand how the active layer, which overlies the permafrost and thaws and re-freezes every year, will respond to environmental change, including climate warming. Active layer thickness can influence hunting, fishing, gathering and forestry through vegetation and soil conditions. The character of the active layer affects transportation and construction, while chan...

Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
Summary: The researchers want to develop a model for small Arctic lakes that will help them see how sensitive or vulnerable Arctic lake ecosystems are to various forms of disturbance, such as future climate change or water withdrawal. In order to develop their m...
