  1. 1. Centennial Climate Variability

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Thomas Askjær; [2022]
    Nyckelord :Climate variability; paleoclimate; climatemodelsimulations; proxyrecords; spectralanalysis; model proxycomparison;

    Sammanfattning : Throughout earths history, the climate have always naturally varied due to both external forcings and internal mechanisms. With the outlook on future climate change, it is important to understand the climate system and this includes its natural variability. Depending on the driving mechanisms, the variability happens over different timescales. LÄS MER

  3. 2. Reconstruction of paleoclimate and loess provenance during the last glacial in Jersey using XRF analysis

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Matilda Persson; [2022]
    Nyckelord :loess; origin; La Motte; XRF; Quaternary; weathering; climate; lössjord; ursprung; La Motte; XRF; kvartär; vittring; klimat;

    Sammanfattning : With our changing climate it becomes more vital to understand the processes that control climate change in order to better understand possible future shifts. By doing this, predictions can be made about future climates and better prepare us for them. LÄS MER

  4. 3. Grain-Size Analysis of Loess Deposits of the Last Glacial Period, NW France

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

    Författare :Linnéa Rodin Borne; [2021]
    Nyckelord :loess; grain-size; glacial; Weichselian; Primel-Trégastel;

    Sammanfattning : Loess is an unique record of the paleoclimate of the Quaternary. Because it is directly deposited from the atmosphere, it can be used as a proxy for wind speed and circulation patterns. It can also be directly dated using luminescence. LÄS MER

  5. 4. En resa tillbaka i tiden för att förstå framtiden : En undersökning av organiskt material i eoliska lössjordssediment på västra Grönland, Kangerlussuaq.

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Caroline Morin; Jessica Sundman; [2021]
    Nyckelord :Greenland; organic carbon; loss of ignition; loess; paleoclimate; Grönland; organiskt material; loss of ignition; lössjordar; paleoklimat;

    Sammanfattning : Today's changing climate on Earth makes climate research more important than ever. By providing an understanding of the Earth's history and in particular places where large-scale climate change is taking place, for example Greenland, can one get an understanding about how the Earth will react in the future.

  7. 5. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pelle Kronborg; [2020]
    Nyckelord :loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Sammanfattning : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. LÄS MER
