Environmental Studies for EL470 - 5yr
Principal Investigator: Belland, Darlene
Licenced Year(s): 2017 2016 2015 2014 2013 2012
Summary: The objective of this project is to conduct ongoing monitoring and assessment programs, including areas in the Mackenzie River Special Management Zone (SMZ), for surface water. Surface water samples will be collected from selected lakes, ponds, rivers, and streams. Selected water bodies in EL470 have already undergone bathymetric assessment and sampling. ConocoPhillips will communicate, in ...


Diavik Aquatics Effects Monitoring Program
Principal Investigator: Wells, David A
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The objective of this project is to revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The AEMP Version 3.5 will consist of the following components; Traditional Ecological Knowledge, Dust Deposition; Effluent and Water Chemistry; Indicators of Eut...


Influence of changing active-layer thickness on permafrost peatland trace gas exchanges and carbon balance
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The project of the present application is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013 as part of licence #15816. The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemometer. These measurements are ...


Radar Remote Sensing of Snow
Principal Investigator: Kelly, Richard
Licenced Year(s): 2017
Summary: The primary objectives of this study are to: 1) understand and explain the role of snow microstructure in terms of the radar backscatter and phase response in this environment; 2) to evaluate the efficacy of differential synthetic aperture radar (dInSAR) for snow accumulation estimates at C-band; and 3) to evaluate the optimal approach to estimating snow water equivalent using radar from this site...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team are interested in how climate change is impacting Arctic rivers. The team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try ...


The Mackenzie Mountains Earthscope Project
Principal Investigator: Schutt, Derek L
Licenced Year(s): 2017 2016 2015
Summary: The Mackenzie Mountains EarthScope project (MMEP) is funded under the EarthScope program of the United States National Science Foundation. This project is collaborating with the larger EarthScope USArray project, which will be studying seismicity (earthquakes) and earth structure in the broader northwestern Canadian and Alaskan regions, and with Canadian researchers from several agencies including...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Mamet, Steve D
Licenced Year(s): 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The objectives of this project are to determine: 1) the status of permafrost landforms; 2) long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; and, 3) Status of treeline. Since 1990, automated microclimate stations powered by solar cells have been operated in the study area. One station is located at each of five permafrost landforms called pal...


Impacts of wildfire extent and severity on caribou habitat
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2017 2016
Summary: The objective is to improve the empirical foundations for predictive caribou habitat mapping within the forested areas of the Taiga Plains and Taiga Shield Ecoregions in the Northwest Territories, roughly south of Great Bear Lake. The research team will establish a network of long-term study plots across a range of fire characteristics and vegetation types, where the team will measure the rate and...


Drivers and consequences of shrub distribution on the tundra landscape
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2017 2016
Summary: The objective is to determine the growth and recruitment responses of trees and shrubs to changing climate conditions near tree line and improve the understanding of the drivers of shrub patch expansion on the tundra. Ten shrub patches were selected for measurement and paired permanent monitoring plots were established at each patch; one plot was centred on the patch of interest, the other on t...


Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this study are to: I) estimate the amount of water equivalent mass the Melville South Ice Cap loses (or gains) on an annual basis, and II) derive a long-term climate record from glacier measurements and weather station data in order to determine trends in climate change for this region of the Northwest Territories. Mass balance is measured at each of the 21 poles across the ic...
