Quantifying permafrost thaw
chercheur principal: Gruber, Stephan
Année(s) de permis: 2019 2018 2017 2016 2015
Résumé: 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...


PermASAR - Airborne SAR campaign on permafrost soils and boreal forests in the Canadian North-West
chercheur principal: Hajnsek, Irena
Année(s) de permis: 2019 2018
Résumé: For this project the research team will conduct the collection of microwave radar backscatter data of permafrost and boreal forest at wavelengths of 3cm (X-band), 6cm (C-band), 10cm (S-band) and 23cm (L-band). This process will capture two stable permafrost active layer states: thawed and frozen. The research team will derive information about permafrost (e.g. soil status, soil moisture) and about...


Application of passive seismic methodologies to the determination of overburden thickness in a permafrost-rich environment
chercheur principal: McPeak, Sara E
Année(s) de permis: 2018
Résumé: The objectives of this project are to test if passive seismics can be used to map the thickness of overburden in a permafrost-rich environment; and, to compare overburden thickness derived from passive seismic data and known overburden thickness from drilling. This project will test to see if the earth’s natural vibration can be used to determine how much sand, gravel, soil and permafrost are a...


DOC in surface waters in the NWT; implications of a changing climate
chercheur principal: English, Michael C
Année(s) de permis: 2015
Résumé: This research focusses upon dissolved organic carbon (DOC) quantity and quality from a suite of hydrological environments underlain by discontinuous permafrost. The research looks to better understand how water quality will be influenced by a warming climate, with specific attention to DOC, by analysing historical water quality data (30 years) from three local rivers (Yellowknife, Cameron, and Mar...
