Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this study are to estimate the amount of water equivalent mass the Melville South Ice Cap loses (or gains) on an annual basis, and to derive a long-term climate record from glacier measurements and weather station data in order to determine trends in climate change for this region of the NWT. Mass balance is measured at each of the ~21 poles across the ice cap as function of s...

A Longitudinal Approach to Community Vulnerability and Adaptation to Climate Change
Principal Investigator: Pearce, Tristan D
Licenced Year(s): 2018 2017 2016
Summary: This research aims to examine the processes and dynamism of climate change vulnerability in the Arctic through a longitudinal study in Ulukhaktok, NWT using fieldwork data from both 2005 and 2016. Specific objectives of this research are: 1) to document current exposure-sensitivities affecting Inuit subsistence hunting and adaptive strategies employed to manage them; 2) to compare current exposure...

BEARWATCH: Monitoring Impacts of Arctic Climate Change using Polar Bears, Genomics and Traditional Ecological Knowledge.
Principal Investigator: Lougheed, Stephen C.
Licenced Year(s): 2018
Summary: This research will integrate and map polar bear knowledge systems and translate findings into a community-based monitoring protocol that will track polar bear population responses to environmental change. Research questions include: 1) Are polar bear science data, existing Traditional Ecological Knowledge (TEK), and historical records from the fur trade, explorer’s personal accounts and government...

Benthic Macroinvertebrate Monitoring (Slave and Hay Rivers)
Principal Investigator: Levasseur, Annie
Licenced Year(s): 2018 2017
Summary: The objectives of this project is to establish a baseline for benthic invertebrates’ community structure and composition in the transboundary reaches of the Slave and Hay Rivers and to track their status and conditions over time to assess ecosystem health and provide an early warning of change or stress in the environment. The monitoring plan involves selecting and sampling several 500m long re...

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
Licenced Year(s): 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...

Impacts of forest fire on discontinuous permafrost in the south-western Northwest Territories
Principal Investigator: Lewkowicz, Antoni G
Licenced Year(s): 2018 2017 2016
Summary: The research goal is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modelled in the future. The fires of 2014 in the southwestern NWT provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration with an inter-university team ...

The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. We are interested in how climate change is impacting Arctic rivers. The research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to det...

Toward Predicting Future Tundra Carbon Balance
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The broad goal of this research is to increase our understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. Since we are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories: 1. Tundra-atmosphere fluxes - the ex...

Boreal Forest Carbon Balance Studies
Principal Investigator: Layden, Ronald E.
Licenced Year(s): 2017
Summary: The objective of this project is to increase the understanding of taiga carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems. The exchange of carbon gases between the taiga and atmosphere is a significant component of the carbon balance and is dependent upon vegetation cover. The description below for the tundra site at...

Evaluation of Climate Change impacts on Transportation Systems
Principal Investigator: Ford, James D
Licenced Year(s): 2017
Summary: This proposed project will develop critical scientific methods for quantifying transportation vulnerabilities and adaptation opportunities, filling knowledge gaps about transportation vulnerabilities and opportunities for action. Designing and implementing an Arctic vulnerability and adaptation index for transportation systems and infrastructure is crucial to improving the understanding of how ...
