Long-term aquatic ecosystem change at the southern limit of permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019 2018
Summary: The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems. 1) Water chemistry and plankton survey The research team will collect lake water samples from the study lakes to analyze for water chemistry...


Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2019 2018 2017 2016
Summary: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...


Landscape scale flooding in the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...


Sensitivities of high-latitude lakes to climatic & development disturbances
Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
Summary: Melting permafrost can alter soils and surface runoff. The effects of such changes have been modeled but never evaluated experimentally. Arctic lake productivity is not well articulated and sensitivities to disturbance (e.g., climate change, water withdrawal for development use) remain unpredictable. The objective of this study is to develop a hydrologic model for melting permafrost conditions, as...


Paleohydrological and Paleoecological Reconstruction of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2007 2006 2005 2004 2003 2002
Summary: This ongoing research project will formulate a history of the frequency and magnitude of floods, droughts, and corresponding ecological responses in the Mackenzie Basin Deltas over the past 1000 years. Fieldwork in 2004 will focus on continued sampling a...
