Investigating the susceptibility of drilling mud sumps to permafrost thaw - ThinIce
chercheur principal: Langer, Moritz
Année(s) de permis: 2024
Résumé: 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...


Waste rock studies at a diamond mine site
chercheur principal: Blowes, David W.
Année(s) de permis: 2014 2013 2012 2011 2010 2009 2008 2005
Résumé: This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...


ArcticNet: an Integrated Regional Impact Study of the Coastal Western Canadian Arctic.
chercheur principal: Fortier, Martin
Année(s) de permis: 2013 2012 2011 2010 2009 2007 2006 2005 2004
Résumé: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into region...
