Lake and River Ice Fieldwork in support of PermASAR data analysis
chercheur principal:
Année(s) de permis: 2019
Résumé: This project aims to undertake fieldwork in the context of the PermASAR winter campaign. The data collected will support the evaluation and development of radar satellite Earth observation (EO) technology for application to the mapping of river and lake ice processes and properties. The research team expect the fieldwork to take place over a period of two to three weeks in the months of Februar...


Do diversity gradients and wildfires interact to facilitate tree range expansion across a broad latitudinal scale?
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: The overarching research goal of this project is to determine what conditions facilitate tree range expansion across the western Canadian boreal-tundra ecotone. Using a biogeographical, multi-trophic level approach, the research team aim to determine: 1. how multi-trophic level species composition changes across the tundra and which conditions dictate these changes; and, 2. the constraints, dri...


Forest Ecotone Experiment
chercheur principal:
Année(s) de permis: 2019 2018 2017
Résumé: 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...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
chercheur principal:
Année(s) de permis: 2019 2018 2017
Résumé: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and m...


Impact of ferry landings on water quality and traditional fish harvesting in the Mackenzie and Peel Rivers
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: Fishing is an important part of the Gwich’in way of life. Concerns in the Gwich’in communities of Fort McPherson and Tsiigehtchic have arisen with regards to the use of granular material in ferry landings. Anthropogenic sediment from ferry landings has the potential to alter river ecology downstream thus impacting valuable fish habitat. This objectives of this project are to determine the impa...


PermASAR - Airborne SAR campaign on permafrost soils and boreal forests in the Canadian North-West
chercheur principal:
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...


Remote Sensing and Geophysics of Tundra Landscapes
chercheur principal:
Année(s) de permis: 2019 2018
Résumé: The proposed project will investigate the possibility of linking field-measured characteristics of tundra landscapes (e.g., active layer thickness, soil moisture, plant distribution and ecosystem composition, etc.) with remotely-sensed data. The overall objective of the project is to identify the connections that exist between observable surface properties and their associated subsurface/permafros...


Northern Native Seed Development Field Trials
chercheur principal:
Année(s) de permis: 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2007 2006
Résumé: The objective of this sub-project are: 1) to continue assessing the performance of native plants which were seeded and transplanted into field plots in 2006 and 2007; and, 2) to establish two new field plots at the Inuvik golf course with the same intent of monitoring native seed performance in a disturbed habitat. The research team intend to collect data regarding winter survival, seedling e...


Comparing the snow depths and densities of different habitats in the Beaufort Delta region
chercheur principal:
Année(s) de permis: 2018 2017
Résumé: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will investigate the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical ...


Sustainable Water Governance and Indigenous Law Project
chercheur principal:
Année(s) de permis: 2018 2017
Résumé: The goal is to enhance effective, equitable Indigenous co-governance of water resources through pursuing five objectives: 1)Critically conceptualize the potential for reciprocal coordination of, and complementarity between, evolving common ("Western") and Indigenous water law and governance frameworks; 2)Develop innovative methods for co-researching Indigenous Water Governance, based on collabor...
