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
Licenced 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...


Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licenced Year(s): 2018 2017 2016
Summary: Our research has three main objectives: 1. to monitor the spatial variability of soil moisture at approximately a 10km resolution in the region of Trail Valley Creek (TVC); 2. to test the soil moisture retrieval algorithms in high organic soils through both satellite based measurements; and, 3. to measure and model the mass wasting at retrogressive thaw slumps as a function of debris thickness...


Synthesis of Glacial History and Dynamics in the Western Rae Geological Province
Principal Investigator: Campbell, Janet
Licenced Year(s): 2018
Summary: The overall goal of this activity is to compile and understand the history of ancient glaciations in mainland Northwest Territories and Nunavut. A field team of 3 people will undertake the work proposed. The field work will be based out of Aylmer Lake Lodge, Aylmer Lake, NWT with the entire crew returning to the lodge at the end of each field day. The field survey will be supported by one hel...


Winter Flow Regime and Icing Dynamics of Tundra Streams near the Inuvik to Tuktoyaktuk Highway
Principal Investigator: Ensom, Timothy P
Licenced Year(s): 2018 2017
Summary: The specific objectives of the project are: 1) determine the spatial extent, distribution, and timing of winter icing events in streams along the ITH through ground-based and aerial reconnaissance of stream crossings; 2) identify relations between physical watershed characteristics and icing dynamics through field observations and analyses of watercourse and catchment morphological parameters in...


Reconstructing history of hummocky soil formation in drunken forest
Principal Investigator: Fujii, Kazumichi
Licenced Year(s): 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 the ...


Forest Ecotone Experiment
Principal Investigator: Eitel, Jan
Licenced Year(s): 2018 2017
Summary: The overarching objective of the study is to integrate light detection and ranging (LiDAR), passive spectral, and tree ecophysiological data to link biophysical structure to ecological function in the Forest Tundra Ecotone. In so doing, the research team will be able to remotely assess the vulnerability and resilience of the forest tundra ecotone (FTE) to environmental change. The field work wi...


De Beers - Gahcho Kué Environmental Monitoring Program
Principal Investigator: Kramers, Patrick
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective of the proposed studies is to obtain information on the environment once Project activities commence to determine potential project effects. The proposed studies will include the collection of air quality, geochemistry, hydrology, water and sediment quality, and fish and aquatic resources, dustfall, vegetation and soil information. The studies (further defined below) are designed...


Planning and Collection of Data on Boreal Wildfire Effects: Studies of broad-scale 2014 Wildfires in NWT, Canada
Principal Investigator: Bourgeau-Chavez, Laura L
Licenced Year(s): 2018 2017 2016 2015
Summary: The goal of this project is to identify and collect remote sensing and field data to support the science necessary to investigate the impacts and consequences of the 2014-15 wildfires in Northwest Territories, Canada and to better understand the vulnerability of the Carbon-rich boreal peatlands to burning. Field crews will navigate to pre-selected sample locations and collect at each location: ...


Remediation of the Abandoned Panarctic Satellite F-68 Wellsite at Satellite Bay, Prince Patrick Island, Northwest Territories
Principal Investigator: Krizan, Julia
Licenced Year(s): 2018 2017 2016 2015 2013 2011 2010
Summary: The objectives of the Site Remediation Program (scheduled to be completed in 2018) are to: 1. Remove and dispose of exposed solid waste (including barrels, batteries, debris, wood, other waste and an existing building); and, 2. Construct a contaminated soil and waste containment structure to contain impacted soil excavated from areas at the site. The 2018 Site activities will include several in...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licenced 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...
