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...


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...


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...


Evaluation of hydro-climatic drivers of contaminant transfer in aquatic food webs in the Husky Lakes Watershed (Inuvialuit Settlement Region, NWT)
Principal Investigator: Gantner, Nikolaus (Klaus)
Licensed Year(s): 2013 2012 2011
Summary: Long term goals of this research: 1. Identify and quantify the physical, chemical and ecological processes that affect contaminant transfer in Arctic aquatic food webs in response to observed and predicted Climate Variability & Change (CVC) in the Husky Lakes Watershed (HLW). 2. Provide people and regulators of Inuvik and Tuktoyaktuk with tools to effectively monitor selected highly valued compo...


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...


PolarDARN - The northern hemisphere polar portion of the international SuperDARN (Super Dual Auroral Radar Network) program
Principal Investigator: Sofko, George J
Licensed Year(s): 2013 2012 2011 2010 2009 2008 2007 2004
Summary: The objective of this research is to measure high and low voltage patterns hundreds of kilometers above the ground and out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications. Radar transmitting and receiving electronics will be installed in a small building with an antenna array outside. A ...


Sensitivities of high-latitude lakes to climatic & development disturbances
Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...


Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2008 2007 2006 2005
Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...


Evaluation of extreme events (ice jams) and deep scour holes on Mackenzie Delta Channels
Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005 2004
Summary: The objectives of this study are to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta, including the hydroclimatic conditions controlling their occurrence and associated floods, develop a hydraulic model of it, and investigate the importance of deep scour holes in the Mackenzie River. This study is an expansion of previous research conducted in 2004. Ice jamming has ...


Extreme Flooding Events in the Mackenzie River Basin
Principal Investigator: de Rham, Laurent
Licensed Year(s): 2004
Summary: It is known that extreme flood levels within the Mackenzie River Basin are caused by ice jamming events. Analysis of open water versus ice influenced water levels at several sites within the Mackenzie River Basin will provide further quantification of th...
