Reconstructing history of hummocky soil formation in drunken forest
Principal Investigator: Fujii, Kazumichi
Licensed Year(s): 2019 2018 2017
Summary: “Drunken forest” is developed on earth hummocks on shallow permafrost layer near Inuvik, Canada. Black spruce forests are typically grown on the shoulder of mounds and tree rings record the history of soil movement. By reading tree rings, The Principal Investigator (PI) is planning to reconstruct history of hummocky soil formation. The PI will collect tree core samples by making a hole in wood...


Short and long term effects of forest fires on the stability of carbon pools in the arctic permafrost and subarctic forests (ARCTICFIRE)
Principal Investigator: Koster, Kajar
Licensed Year(s): 2018 2015
Summary: The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes. The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licensed Year(s): 2017
Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...


Nutrient Availability in Arctic Tundra Soils
Principal Investigator: English, Michael C
Licensed Year(s): 2008
Summary: This licence is issued for the scientific research application # 876. The objective of this research is to determine the impacts of predicted soil warming scenarios for the arctic on the availability of phosphate, nitrate-nitrogen and ammonium, which are important soil nutrients. The field portion of this research will consist of two weeks of collecting soil data and gauging and sampling (f...


Canadian Tundra Climate Exchange Project
Principal Investigator: Lafleur, Peter M
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The purpose of this study is to examine carbon exchange between the arctic tundra and the atmosphere. Specifically, the researchers are interested in variation in carbon exchange in response to environmental factors such as soil moisture and weather (tem...
