Principal Investigator: Hille, Erika C
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5596. The objectives of this study are to conduct spatially detailed surveys of water quality and stream discharge along the Miner River, in order to examine how water quality responds to organic-rich peatland tributary streams and retrogressive thaw slumping; and, to examine the seasonal water quality of Caribou Creek and...

Principal Investigator: Morse, Peter D
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5797. The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the ISR and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment. The first year of field activit...

Principal Investigator: Kunz, Julius
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5655. This project aims to investigate the three-dimensional subsurface structures in the vicinity of active retrogressive thaw slumps and their relationship to spatio-temporal slump-development. The number and activity of retrogressive thaw slumps have increased during the last decades due to climatic, hydrologic and ther...

Principal Investigator: Wild, Birgit
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5564. The main goal of the project is to understand how gradients in tundra vegetation and permafrost thaw affect soil carbon and mercury cycling. This will allow the research team to assess how permafrost thaw and changes in vegetation in a warmer climate could alter future carbon dioxide fluxes and impact mercury cycling ...

Principal Investigator: Grosse, Guido
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5656. The objective is to conduct airborne surveys at 3300ft (1000m) altitude to collect high-resolution aerial images and LiDAR elevation data that can be used to describe and quantify rates of permafrost thaw, coastal erosion, thaw slumping, lake change, and vegetation change. Daily survey flights (depending on cloud-fre...

Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No. 5597. The objective of this research is to understand how permafrost slumping increases the mobilization of carbon, nutrients, and toxins (mercury) from land to water, and the effects of this transport on stream ecosystems and the global carbon cycle. Over the next several years, the research team plan to measure stream ch...

Principal Investigator: Thienpont, Joshua
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5573. To understand how landscape changes caused by climate warming are impacting aquatic ecosystems, particularly lakes and streams. These disturbances focus primarily on permafrost thaw, in the form of thaw slumps and landslides. The understanding derived will allow better understanding of how water quality and aquatic ha...

Principal Investigator: Overduin, Pier Paul
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5561. Through ERT and PS methods, the extent and depth will be mapped to the top of ice-bearing permafrost (IBP) offshore of Tuktoyaktuk Island. On land, ERT surveys will also reveal information on permafrost characteristics like ice content, but offshore, tools can only reliably map the thickness of the unfrozen body (tali...

Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5568. The primary objective of this project is to link long-term records of ground temperature and permafrost conditions with changes in landcover and water quality of adjacent ponds and lakes. In other words, how thawing permafrost alters terrestrial and aquatic ecosystem properties. Along the Mackenzie Valley corridor...

Principal Investigator: Alvarez, Alejandro
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5420. The objectives of this study are to: 1) evaluate the geologic setting including geochemistry, and dating of sediments to establish a regional history of the area; 2) investigate the geologic setting of multiple buried, massive ice bodies; and 3) develop a geologic and hazards map along the Inuvik to Tuktoyaktuk Highwa...
