Mapping for Ground Ice along the ITH
chercheur principal: Alvarez, Alejandro
Année(s) de permis: 2024 2023 2022
Résumé: 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...

Understanding changes in aquatic ecosystem health and water quality in the Fort Good Hope – Ramparts Area
chercheur principal: Gurney, Kirsty E.
Année(s) de permis: 2019 2018 2017
Résumé: The project aims to build community partnerships, identify field sites, and develop and implement sampling protocols for long term, community-based, monitoring of wetland ecosystems near Fort Good Hope (FGH). Whereas some wetlands in the study area have either already been, or are likely to be, impacted by a wide range of industrial activities, including development of oil and gas and associat...


Slave Province Surficial Geology and Permafrost Study
chercheur principal: Elliott, Barrett R
Année(s) de permis: 2017 2015
Résumé: The objectives of the research are to generate new surficial geology maps and surficial geological studies covering approximately 5 50k National Topographic System (NTS) sheets, to install an new permafrost monitoring network at the treeline transition as well as to generate case studies of using small soil samples to detect a buried kimberlite and using passive geophysics equipment (measures eart...


Terrestrial geoscience studies of earthquake (seismic) hazard in the Mackenzie-Beaufort area
chercheur principal: Dallimore, Scott R
Année(s) de permis: 2015 2014
Résumé: 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....


North Slave Permafrost Study: Characterizing and Predicting Discontinuous Permafrost for Climate Change Adaptation
chercheur principal: Wolfe, Stephen A
Année(s) de permis: 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010
Résumé: This activity will describe and predict the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Future changes in climate will affect permafrost distribution, temperatures and geotechnical conditions. It is anticipated that different landscapes across the region will exhibit vary...


The cumulative impacts of rapid environmental change in the northwestern NWT: Investigating the impacts of mega-slump disturbances on terrestrial and aquatic ecosystems in the lower Peel watershed, NW
chercheur principal: Lacelle, Denis
Année(s) de permis: 2013 2012
Résumé: This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to : 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of strea...


Environmental Studies Across Treeline
chercheur principal: Kokelj, Steven V
Année(s) de permis: 2012 2011 2010 2009 2008 2007 2006 2005
Résumé: “Environmental Studies across Treeline (ESAT) in the Mackenzie Delta region” is a northern based collaborative program with an objective to enhance the understanding of environmental conditions in the Mackenzie Delta region through scientific studies and monitoring. Specific studies include: 1) monitoring permafrost conditions in the Mackenzie Delta region; 2) examining freeze-back of the active l...


Duration of active-layer freeze back, Illisarvik, NWT
chercheur principal: Gilbert, Graham L
Année(s) de permis: 2010
Résumé: The objectives of this project are to define the impact of snow depth, surface vegetation, and soil characteristics on spatial and temporal variations in active-layer freeze-back in the low arctic tundra east of the Mackenzie Delta. The duration of freeze back will be determined from the ground temperatures measured at the top of permafrost. This temperature only declines at the site when the ac...


Land Management Problems in Hydrocarbon Development Areas with Ice-Rich Permafrost: Detection and Assessment
chercheur principal: Pollard, Wayne H
Année(s) de permis: 2010 2009
Résumé: This licence is being issued for the scientific research application no. 946. The objective of this research is to better understand the distribution of underground ice in hydrocarbon development areas. By identifying how much ice there is, the researcher wants to study how oil/gas activities and climate change could affect the land. Underground ice is one of the most unpredictable and problema...
