  1. 6. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Margot Jeanne Knapen; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Sammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER

  3. 7. THE INFLUENCE OF TUNDRA VEGETATION ON SOIL TEMPERATURES

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Edith Aspelin; [2022-09-28]
    Nyckelord :;

    Sammanfattning : The arctic has experienced more rapid global warming and is more sensitive to temperature changes compared with the rest of the world. We can already see how vegetation distributed across the arctic tundra has changed in composition, height, and abundance. LÄS MER

  5. 9. Seasonal permafrost subsidence monitoring in Tavvavuoma (Sweden) and Chersky (Russia) using Sentinel-1 data and the SBAS stacking technique

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ida Rehn; [2022]
    Nyckelord :InSAR; Sentinel-1; SBAS; Permafrost; Subsidence; Permafrost thaw;

    Sammanfattning : Permafrost deformation is expected to increase due to climatic perturbations such as amplified air and soil temperatures, resulting in permafrost thawing and subsequent subsidence. Palsas and peat plateaus are uplifted ice-rich peat mounds that experience permafrost subsidence. LÄS MER

  7. 10. GIS, tracer test and water balance based hydrological analysis in Tarfala, Northern Sweden

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Elias Koivisto; [2022]
    Nyckelord :Tarfala; DEM; Tracer test; Water balance; the Arctic; Climate change; Permafrost; Glacier;

    Sammanfattning : Current climate change poses a threat to the Arctic due to increasing temperatures, which cause the permafrost and glaciers to melt and thaw. This thesis focused on analyzing water balances in Tarfala catchment between 2000 and 2020 and using GIS as a support for tracer test results measured in Tarfala in 2021. LÄS MER
