This scientific research project led by professor Stephanie Kusch (University of Quebec Rimouski) will investigate changes in permafrost organic carbon remineralization and erosion in response to climate change. Activities performed by a team of 3 university researchers during the duration of the project (yearly sampling for 2-3 weeks in July/August from 2025 to 2028) include permafrost soil sampling to study greenhouse gas production and organic matter transformation as well as sampling of marine sediments (0-2cm depth) to study erosion of permafrost organic carbon into the ocean and oceanic feedback mechanisms. Soil samples will be taken from small 15x15cm soil pits reaching the permafrost table (30-50cm depth) and sediments will be taken using small grab samplers. Samples will be brought back to the laboratory at the University of Quebec Rimouski for direct analysis and long-term incubations in the laboratory. The observations made in this research project will be linked to longer sediment records to understand past permafrost dynamics beyond observational records, which allows assessing the sensitivity and response of permafrost OC to natural climatic as well as anthropogenic forcing and helps predicting the future response of permafrost to climate change. This research will aid the community of Qikiqtarjuaq better understand on-going changes in the environment and their fishing and hunting grounds.The researchers will use the new Qikiqtarjuaq research station operated by Laval University, which handles all waste disposal. No environmental impact on the land is expected. No chemicals or plastics will be used for sampling. Equipment cleaning protocols will be followed to prevent any import of invasive species. Sample volumes are small (500ccm) and soil pits will be closed after sampling so that they do not represent any safety concern.
