  1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Namika Maharjan; [2023]
    Nyckelord :Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Sammanfattning : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. LÄS MER

  3. 2. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :June Johansson; [2023]
    Nyckelord :Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Sammanfattning : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. LÄS MER

  4. 3. Minskning av palsmyrar som resultat av klimatförändringar i norra Sverige mellan 1960–2020

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :My Apelkvist; [2023]
    Nyckelord :palsmyrar; palsar; norra Sverige; carbon feedback; klimatförändringar;

    Sammanfattning : The climate is changing at a rapid rate. This causes both an increase in temperature and precipitation in the northern high latitudes. Subarctic peatlands contain 30% of the carbon storage in the northern permafrost zone. LÄS MER

  5. 4. 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

  7. 5. 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
