Impacts of permafrost thaw on hydrology and water resources
Principal Investigator: Quinton, William L.
Licensed Year(s): 2019 2018 2017
Summary: Understanding the ecology and hydrology of ecosystems with thawing permafrost is a major challenge. To meet this, the research team will develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bogs, fens, peat plateaus) needed to develop new science-based tools to predict the future supply for the next 50 years. The specific scientific objectives are: 1) Develop fundamental knowl...


Nunataryuk WP4: Satellite tracking of the organic matter in the Mackenzie Delta, impact of climate change on permafrost thaw
Principal Investigator: Babin, Marcel
Licensed Year(s): 2019
Summary: The specific objectives of this project are: 1) to document trends in export of coastal, riverine and subterranean dissolved and particulate organic matter and carbon into the Arctic Ocean; 2) to determine their fate and related processes (origin and age, transport, physical, chemical, and biological transformation) in coastal waters and estuarine sediment; and 3) to assess the impacts of thes...


Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objective of this research is to characterize the long-term (>50 years) climatic conditions and annual rate of mass change for the Melville ice cap, NWT. Glacier mass balance is defined as the difference between the amount of snow accumulated on a glacier (generally termed winter balance) and the amount lost due to melt (summer balance) over the course of a given year. Due to logistical co...


Capitalizing on long-term experimental manipulations to understand and predict arctic terrestrial ecosystem responses to climate warming
Principal Investigator: Grogan, Paul
Licensed Year(s): 2019
Summary: The objectives of this research project are: 1) to determine the biogeochemical and ecological significance of our discovery that mesic tundra plant growth can be co-limited by nitrogen (N) and phosphorus (P); 2) to predict the likely impacts of not just climate change, but also declining caribou and other mammalian herbivory, on tundra deciduous and evergreen shrub abundances; and, 3) to evaluate...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licensed Year(s): 2019 2018 2016 2015 2013 2012 2011 2010 2009 2008 2007 2006
Summary: Objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the patter...


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...


Quantifying permafrost thaw
Principal Investigator: Gruber, Stephan
Licensed Year(s): 2019 2018 2017 2016 2015
Summary: The objectives of this research are: 1) to understand better how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) to understand how these different types of permafrost respond to change (climate/disturbance); and, 3) to understand which future changes in permafrost are likely and which are less likely based on computer simulations. High-quality mea...


Benthic Macroinvertebrate Monitoring (Slave and Hay Rivers)
Principal Investigator: Levasseur, Annie
Licensed Year(s): 2019 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...


Sahtú Benígodi: Traditional Knowledge of Great Bear Lake and its Watershed
Principal Investigator: Spring, Andrew
Licensed Year(s): 2019 2018
Summary: The purpose of this project is to build a comprehensive database of Traditional Knowledge of the Great Bear Lake and its watershed to form an environmental baseline for the cumulative impacts of climate change and development. By compiling the rich history and stories from existing literature, studies and other initiatives from the community, the research team will be able to build a comprehensive...


Food systems and community well-being in Kakisa, NT
Principal Investigator: Spring, Andrew
Licensed Year(s): 2019 2018
Summary: The objectives of this research project are to: 1. foster training and knowledge sharing to ensure that traditional foods continue to provide an important component of affordable, sustainable healthy food system for Ka'a'gee Tu First Nation(KTFN); 2. conduct a detailed needs assessment for a food security action plan; 3. increase knowledge and capacity to grow and produce food products while ex...
