Assessment of the Western Arctic Boundary Current
Principal Investigator: Pickart, Robert S.
Licenced Year(s): 2018 2013 2012 2011 2010
Summary: The main objective is to characterize the western Arctic Boundary current (which flows at the edge of the shelf), in order to understand its role in dictating shelf-basin exchange of water and materials and how it impacts the ecosystem of the region, including the occurrence of marine mammals. This project is a collaboration between US and Canadian scientists. The research team are using a comb...


NASA ABoVE Airborne Campaign 2018 Addendum
Principal Investigator: Miller, Charles E
Licenced Year(s): 2018 2017
Summary: The extended Arctic-Boreal Vulnerability Experiment (ABoVE) Study Area includes most of northwestern North America west of Hudson Bay and north and east of the coastal mountain ranges. The core study area includes 4 jurisdictions: Alaska, Yukon, Northwest Territories, and Nunavut. It encompasses the variability in the key types of ecosystems that are both unique to arctic and boreal regions in Nor...


Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
Principal Investigator: Hille, Erika C
Licenced Year(s): 2018
Summary: The objectives of this project are to: 1) create a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk; 2) develop detailed water, vegetation, and ground temperature maps of the study sites using drones; 3) examine the effects of thaw slumping on the water quality of landscape-level runoff to the Beaufort Sea; 4) examine the effects of coastal erosion ...


Shale Basin Evolution 2
Principal Investigator: Fiess, Kathryn M
Licenced Year(s): 2018
Summary: This year’s objective is to complete the work at the selected locations by obtaining a full suite of rock samples for analysis, photograph each location, and measure natural radiation. At each site, the rock exposure will be photographed in detail. Natural radiation will be measured every half meter using a sensor without major disturbance of the rock face. At each location, rock samples weigh...


Online Digital Hazard Maps of Landslides Along the Caribou Hills
Principal Investigator: Giff, Garfield
Licenced Year(s): 2018
Summary: The main objective of the project is to develop and disseminate through a geoportal, hazard maps and additional information to support the development and implementation of climate change adaptation strategies for the Caribou Hills. Within the geoportal, spatial and non-spatial information will be available to inform: regulations, the community of the possible danger, vulnerability assessments, th...


Application of passive seismic methodologies to the determination of overburden thickness in a permafrost-rich environment
Principal Investigator: McPeak, Sara E
Licenced Year(s): 2018
Summary: 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...


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...


Global and regional environmental signals of the Mississippian/Pennsylvanian strata in the Liard Basin Northwest Canada
Principal Investigator: Fedorowski, Jerzy A.
Licenced Year(s): 2018
Summary: The principal aim of this project is to examine the settlement, development and decline of the fossil corals as a response to environmental conditions in the Liard region during Mississippian to early Pennsylvanian times (358.9 to 314.6 million years ago). The study will be conducted against the background of the world-wide expansion of corals in the Viséan age (346.7 - 330.9 million years ago) an...


Landscape Response from Altering Ice-Rich Terrain
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2018
Summary: The goal of this study is to understand landscape response following ice-rich terrain alteration. The research team will install temperature loggers in 2" PVC pipe from the surface down to 3 m depth to monitor the ground temperature evolution over the summer season in the pits. The team will also use the geophysical technique electrical resistivity tomography (ERT) to measure the amount and st...


Impacts of 10 years of climate warming on forests and peatlands in the Dehcho
Principal Investigator: Errington, Ruth
Licenced Year(s): 2018
Summary: After 10 years of warming climate conditions, the Canadian Fire Service is leading a field project to re-measure a series of permanent monitoring plots to identify any changes to the forest stand structure, tree growth rates, plant community composition, tree, shrub, herb, and lichen biomass. These changes will be associated with climate trends and environmental factors such as soil type, presence...
