Watershed delineation of permafrost disturbance on eastern Banks Island, NWT: a geomatic approach for predicting water quality impacts
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2015
Summary: The objective of this work is to investigate the impact of permafrost disturbance on water quality by examining varying sizes of watersheds with different magnitudes of disturbance. The impact of disturbance on water quality will be examined in a number of different research questions: 1) does watershed size impact downstream water quality where there is the same magnitude of disturbance; 2) is wa...


Effects of permafrost disturbances on terrestrial and aquatic ecosystems, Banks Island, NWT, Canada
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2015
Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...


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
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2013 2012
Summary: 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 Tree Line
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...


Modified Phase II Environmental Site Assessment O-35 Wellsite
Principal Investigator: Miller, Samantha
Licenced Year(s): 2003
Summary: The objectives of this assessment are to conduct a site investigation to evaluate potential environmental impact associated with daily facility operations associated with the O-35 wellsite. In August 2002, an Environmental Site Assessment was conducted....


Modified Phase II Environmental Site Assessment N-01 Wellsite
Principal Investigator: Miller, Samantha
Licenced Year(s): 2003
Summary: The objectives of this assessment are to conduct a site investigation to evaluate potential environmental impact associated with daily facility operations associated with the N-01 wellsite and to set up background concentrations of parameters for the lea...


Modified Phase II-III Environmental Site Assessment F-36 Wellsite
Principal Investigator: Miller, Samantha
Licenced Year(s): 2003 2002
Summary: The objectives of this assessment are to conduct a soil investigation and remediation associated with the flare stack at the Paramount Resources Ltd. F-36 Wellsite. In August 2002, a modified Phase II Environmental Site Assessment was conducted. The bas...


Mass movements in the Aklavik Mountains and Water Quality in the Richardson Mountain Catchments
Principal Investigator: LAURIOL, Bernard
Licenced Year(s): 1998
Summary: The aim of the study of mass movements in the Richardson Mountains is to understand the processes of erosion related to climate changes. The site to be studied is located south of Little Fish Creek. The landscape looks like bench forms which are named Cryoplanation terrasses. This site was visited last year for 2-3 hours. Their formation are not really understood but we suspect that the melting of...
