Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2022 2021 2019 2018 2017 2016 2015 2014 2013
Summary: The objectives of this research project are to: 1) determine if the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the discontinuous and continuous permafrost zones; 3) determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale...


Arctic Peatland Carbon and Holocene Warm Climates
Principal Investigator: Beilman, David W
Licensed Year(s): 2013
Summary: The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...


Community based permafrost and active layer monitoring program
Principal Investigator: Yoshikawa, Kenji KY
Licensed Year(s): 2013
Summary: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...


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
Licensed 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...


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licensed Year(s): 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team also intends to investigate the ice content of the ground and how this may affect terrain stability. The research team wishes to study changes in ground temperature at various locations in the western Arctic, ranging from Her...


Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
Principal Investigator: Vonk, Jorien
Licensed Year(s): 2011 2009 2007
Summary: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...


Investigations of the water cycle and hydrological processes of the subarctic Canadian Shield
Principal Investigator: Spence, Christopher
Licensed Year(s): 2017 2016 2012 2011 2010 2009 2008 2007
Summary: The objective of this project is to determine the relationships between climate, stream flow, water chemistry and permafrost in the subarctic Canadian Shield. The work will take place within a research basin framework. The study will take advantage of significant existing infrastructure that includes one Indian and Northern Affairs Canada and three Environment Canada climate towers, a Water Su...


Vegetation Monitoring and Science Training in the Mackenzie Delta Region
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2011 2010
Summary: There are two objectives associated with this research. The first is to establish vegetation and permafrost monitoring sites in the region. The establishment of these permanent monitoring sites will improve our understanding of base-line environmental conditions in the region. The second goal for the 2010 monitoring season is to build local capacity for monitoring vegetation and permafrost in t...


Investigations of ground ice development in sediments of the Mackenzie Delta area.
Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The purpose is to collect samples of ground ice and to measure air, ground and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousand years, in order to determine what might happen in the future....


Ecological & geomorphological investigations in the alpine tundra of the western Mackenzie Mountains
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. In the spring and winter fixed wing access is arranged from Tulita. Automated microclimate stations powered by solar energy cells operate year-round. The base camp at Camp 222 includes solar cells to power laptop computers. Three field data collection visits are planned: May-June, July-August and February. ...
