Response of Nitrogen Fixation in Lichens and Mosses to a Rapidly Changing Arctic Environment
Principal Investigator: Cassar, Nicolas
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5273. This project will collect lichen, bryophyte (moss, liverwort and hornwort) and soil samples from Dundas Peninsula and north Banks Island while traveling on the French ecotourism ship Le Commandant Charcot during a cruise through the Northwest Passage from Iceland to Alaska. The project will be carried out opportunisti...


PALEO-THAW: Unlocking records of past permafrost thaw through isotopes of fossil bones
Principal Investigator: Murton, Julian B
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5255. The main objective of the project is to establish the causes of the major changes in sulphur isotopes recorded in fossil bones of mammals at the end of the ice age. To achieve this, the research team will test the working hypothesis that major changes in fossil bone collagen sulphur are linked to changing biogeochemic...


Diavik Frame Lake Aerator Program
Principal Investigator: Sinclair, Sean
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5302. There are two objectives: 1) determine if installing an aerator in Frame Lake, Yellowknife, NT, will increase dissolved oxygen levels in the lake such that fish can be reintroduced; and 2) if phase 1 proves successful, transfer fish into Frame Lake and monitor growth and reproduction to determine if the population is ...


Investigating the age and geochemical origins of the mixed (NYF+LCT) pegmatites at the O’Grady Batholith, Northwest Territories, Canada
Principal Investigator: Groat, Lee A.
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5299. The main objectives of this fieldwork are to: 1) constrain the connection between the Niobium-Yttrium-Fluorine (NYF) and Lithium-Cesium-Tantalum (LCT) pegmatites; 2) assess the parental connections to the granite batholith which will provide insight into the evolution of melt over time, leading to a deeper understandi...


Understanding the potential impacts of rare earth elements in aquatic systems in the NWT.
Principal Investigator: McGeer, Jim
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5300. The objectives of the project are to develop data on the aquatic toxicology of rare earth elements in northern ecosystems and to contribute to water quality criteria for these metals. Three types of sample collections are proposed: 1) Water samples of approximately 0.5 L will be collected in pre-cleaned bottles ...


The Effect of Channel Network Geometry of Nitrate Removal in Arctic Deltas
Principal Investigator: Knights, Deon Hanley
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.4926. To improve the understanding of biogeochemical cycling in arctic deltas, the principal investigator (PI) propose fieldwork to characterize nitrate processing rates across a range of streams and lakes on the Mackenzie delta. This field expedition will primarily consist of the following three methods: 1) solute trac...


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...


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): 2023 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): 2023 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 ...
