  1. 6. En varmare värld. En studie om klimatförändringarna vid den tidiga mesolitiska perioden i England och Doggerland

    Kandidat-uppsats,

    Författare :Sarita Engström; [2022-03-10]
    Nyckelord :Climate change; Prehistory; Ecosystems; Early Mesolithic; England; Doggerland; Hunter-gatherer; Landscape; Glaciers; Oceans; Vegetation; Fauna;

    Sammanfattning : The climate change that is currently threatening parts of the world's population and the planet's ecosystems is influenced by the global warming of our planet. This has led to significant research studies on the contemporary climate crisis. Looking at our prehistory, there have been major climate changes that affected prehistoric man. LÄS MER

  3. 7. Arktis - det nya slagfältet : En kvalitativ studie över Sveriges och USA:s säkerhetsstrategi för den arktiska regionen

    Kandidat-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Ida Röjerås; Sara Trogen; [2022]
    Nyckelord :Sweden; The United States; Arctic; Security strategies;

    Sammanfattning : As temperatures in the Arctic continue to rise, so do the tensions between the Arctic states as Russia and China belligerently stake their claims in the Arctic region. Before the crippling effects of climate change, the Arctic was a region that was hard to gain access to due to the colossal glaciers that provided a natural barrier that kept countries at bay.

  4. 8. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thibault Desjonquères; [2022]
    Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

  5. 9. 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

  7. 10. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

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

    Författare :Daniel Estmark; [2022]
    Nyckelord :Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

    Sammanfattning : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.
