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 licence has been issued for the scientific research application No.5007. The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the Inuvialuit Settlement Region (ISR) and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment. ...

Summary: The research goals are to ascertain the formation of marine pock marks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from the release of methane from degrading or thawing offshore permafrost. The research team intend to document the ...

Summary: This research will take place onboard the Canadian Coast Guard Service icebreaker Sir Wilfrid Laurier during its annual multi-tasked Arctic Patrol that traverses the Canadian western Arctic. The research shares the logistics with the Department of Fisheries and Oceans Canada researcher Dr. Humfrey Melling. This work builds on marine research expeditions onboard the Laurier in 2010, 2012 and 2013. ...

Summary: Industry and regulators require information on seismicity and its effect on engineering structures both at a regional and local scale. The primary source of this information is the National Building Code of Canada’s Seismic Hazard Value map. Ongoing work undertaken as part of the 2015 revision of this map suggests that an increased seismic (earthquake) hazard exists in the Mackenzie-Beaufort area....

Licensed Year(s): 2014
Summary: This proposed research focuses on the collection of small sediment/pebble samples from known terrestrial glacial deposits at coastal exposures at various locations in the Inuvialuit Settlement Region (ISR). These sites each have different stratigraphic settings and existing published interpretations of glacial source and providence. The results from these investigations should enable direct c...

Licensed Year(s): 2017 2014 2013
Summary: The agencies involved are undertaking this research to acquire geoscience knowledge about the outer shelf of the Beaufort Sea with intent to address knowledge gaps related to thawing of subsea permafrost and gas hydrates. The research will be made publicly available to northern communities, regulators, the scientific community and industry through the release of scientific papers, maps and reports...

Licensed Year(s): 2012 2011 2010 2009 2008 2007 2006 2004
Summary: Field research for 2010 will concentrate on two tasks: 1) Continued characterization of three of the larger gas seeps observed and reported by the National Energy Board, GSC and Inuvialuit; 2) Identification of additional seeps in the region through aerial surveys, regional studies of geology and gas release on Richards Island and Tuktoyaktuk Peninsula. The researcher will characterize w...

Licensed Year(s): 2008 2007 2002 1998
Summary: The objectives of the study are to: characterize gas hydrates at Mallik using state-of-the-art well log data; collect high-quality core samples for measurement of gas hydrate production parameters (e.g. hydraulic permeability, thermal conductivity, pore water geochemistry); conduct ground temperature monitoring to depths of greater than 1 km to evaluate gas hydrate stability; integrate data to bet...
