Investigating the seasonality of subarctic lakes in a changing climate using satellite & field data
Principal Investigator: Kheyrollah Pour, Homa
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5335. This proposed research is directed at understanding the impact of current/future climate warming on subarctic lake ecosystems. The aim is to explore the relationship of seasonal lake ice growth/ablation and water quality across a wide range of lake characteristics (size, volume, productivity, catchment characteristics...


Wetland status, change, and seasonal inundation dynamics for assessing the vulnerability of waterfowl habitat within the ABoVE study domain
Principal Investigator: French, Nancy H
Licensed Year(s): 2022 2020 2019
Summary: This licence has been issued for the scientific research application No.5205. The main project goal is to characterize changes in waterfowl habitat using remote sensing approaches developed during prior NASA ABoVE research campaigns. The first objective is to create wetland type and surface inundation products (maps) for the ABoVE boreal region. The second objective is to assess the efficacy of...


Monitoring cumulative effects to water quality: An NWT Pilot Study
Principal Investigator: Chin, Krista
Licensed Year(s): 2022 2021 2020
Summary: This licence has been issued for the scientific research application No.5328. The objective of this project is to collect water quality data from regionally-representative lakes that can inform resource management decisions on cumulative impacts within the Northwest Territories (NWT). Using a computer program the research team will select 30 lakes within the Daring Lake area based on expect...


Measuring and simulating permafrost thaw
Principal Investigator: Gruber, Stephan
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5114. The objectives of this project are to understand: 1) how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) how these different types of permafrost react to change (climate/disturbance); and, 3) which future changes in permafrost are likely and which are less likely based o...


Basin Analysis of the Imperial Formation
Principal Investigator: Terlaky, Viktor
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5283. This research study aims to fill the existing knowledge gaps about the Imperial Formation, including its regional sedimentology and stratigraphy (what types of rocks do we see regionally; how do they change vertically and laterally), ichnology and paleontology (what kind of fossils/traces do we see in the rocks). Addi...


Characterization of recent permafrost landslides and ground ice distribution in the central Mackenzie Valley, NWT
Principal Investigator: Froese, Duane G
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5318. This work builds on studies over the last several years, including field work in the Mackenzie River valley in 2018 and 2019. The objective of 2021 fieldwork is twofold: 1) characterizing a large suite of retrogressive thaw slumps and thaw-induced landslides in the Redstone, Keele, and Johnson River basins that have i...


Terrain factors influencing the water quality of peatland streams along the Inuvik-to-Tuktoyaktuk Highway
Principal Investigator: Hille, Erika C
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5295. The objective of this project is to examine the oxygen (d18O) and hydrogen (d2H) isotopic compositions of stream water and precipitation for 11 peatland stream watersheds along the Inuvik-to-Tuktoyaktuk Highway (ITH). This information will be used to understand the hydrology of the contributing watershed. In particula...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Mamet, Steve D
Licensed Year(s): 2022 2021 2020 2019
Summary: This licence has been issued for the scientific research application No.5282. Objectives of this research project are to determine: 1) the status of permafrost landforms; 2) long-term recovery after abandonment of the CANOL No. 1 project, including oil spills and gravel pits; and, 3) the status of treeline. The research team will be examining the permafrost by thaw depth probing, and automat...


Soundscape ecology to assess environmental controls on wildlife
Principal Investigator: Boelman, Natalie
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5265. The project objective is to install 3 Automated Recording Units (ARUs) that will collect daily audio recordings that will allow the research team to understand how variation in environmental conditions affect habitat use by birds. In April, the team will temporarily attach 3 ARUs onto 3 trees (using bungee cord or ...


Remote Sensing and Geophysics of Tundra Landscapes
Principal Investigator: Ullmann, Tobias
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5193. The research team 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 connection that exist bet...
