Implications of climate change and permafrost thaw on carbon dynamics and biodiversity in the lower MRB watersheds
Principal Investigator: Reid, Thomas
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5507. The objectives of this research are to: 1) Assess the spatial and temporal distribution of particulate and dissolved nutrients/carbon along a large- and small-scale latitudinal gradients in the MRB (I.e. Slave River, Great Slave Lake, Mackenzie River, Laird River, Peel River, smaller headwater streams); Correlate...


THAWPOND-NWT – Remote sensing analysis of vegetation and thaw pond colour dynamics in the continuous permafrost zone: from local to regional (Northwest Territories, Arctic Canada)
Principal Investigator: Vieira, Gonçalo
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...


Using computer models to understand what influences mercury levels in the Beaufort Sea Shelf food web
Principal Investigator: Giang, Amanda
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5518. The objectives of this project are to develop and apply a computer model of mercury bioaccumulation in the Beaufort Sea Shelf food web; to estimate the effects of selected environmental changes on historical Beaufort Sea beluga MeHg concentrations from (1970-2010s); and, to investigate potential future trajectories of...


Landscape Change in the Western Arctic
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5594. The main goal is to use remote sensing (Landsat, QuickBird, InSAR, Airphotos, and Remotely Piloted Aerial Systems (RPAS)) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.). 2) Use field sampling and monitoring t...


Recent, rapid environmental change in the western Canadian Arctic
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...


Impacts of permafrost thaw on land cover and downstream water quality
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...


Tundra shrub response to climate change-exacerbated disturbances
Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5567. This project has two primary objectives: 1) To investigate the differences in shrub productivity traits between undisturbed and disturbed tundra sites to better understand the impact of shrub expansion and disturbance on ecosystem function. 2) To investigate the impact of shrub productivity trait differences on deco...


Understanding carbon and water fluxes in the forest-tundra ecotone across scales
Principal Investigator: Sonnentag, Oliver
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5536. The project brings together expertise from historically separated knowledge systems and scientific communities, integrating Indigenous perspectives with atmospheric biogeosciences, ecology, airborne remote sensing, and computer science. The project builds on the collective desire to engage community members in knowled...


Detecting Upriver Climate Change Effects in the Mackenzie River (DUCCEM)
Principal Investigator: Juhls, Bennet
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5542. The proposed project aims to directly observe seasonally strongly variable organic carbon concentrations and chemistry of the Mackenzie River and thus its fluxes to Arctic coastal waters. The research team aim for weekly observations of Mackenzie River biogeochemistry during a period covering the major phases of the h...


IceBird Winter 2023
Principal Investigator: Krumpen, Thomas
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5486. IceBird Winter 2023 is part of a long-term sea ice observation program within the IceBird aircraft campaign series. IceBird was initiated in 2018 with the objective to ensure the long-term availability of a unique data record of direct sea-ice thickness observations to understand the role of the sea ice component for ...
