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...

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...

Aklavik Elder's Traditional Knowledge, Climate Change and Community Health
Principal Investigator: Archie, Billy
Licensed Year(s): 2010
Summary: The goal of this research project is to gather current and traditional knowledge directly from local Elder's/Hunter's that have made observations of the climate changes experienced/observed within the last two decades, and help identify what species have benefited, or what species they think are at risk from climate change. It will validate the elder's and hunter’s knowledge and contribute to com...

Treeline Dynamics in Western Canadian Arctic
Principal Investigator: Green, Scott
Licensed Year(s): 2009 2008
Summary: The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...

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...
