  1. 1. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joakim Edlund; [2022]
    Nyckelord :Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Sammanfattning : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. LÄS MER

  3. 2. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Susanna Åberg; [2022]
    Nyckelord :aeolian dust; Romont; Europe; true loess line; past climate reconstruction; vindtransporterat stoft; Romont; Europa; true loess line; rekonstruktion av tidigare klimat;

    Sammanfattning : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. LÄS MER

  4. 3. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elias Hero; [2022]
    Nyckelord :;

    Sammanfattning : Loess is a very fine aeolian sediment that can be used as a proxy for stadial and interstadial glacialperiods. To understand how Earth’s climate have changed and what effects that change have had on theplanet and life on it we can use climate archives. LÄS MER

  5. 4. Post-IR IRSL dating of K-feldspar from Loess at Lowland Point, SW England : Developing a Chronology for Past Climate Records

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elin Törnqvist; [2022]
    Nyckelord :loess; post-IR IRSL; Lowland Point; SW England; Quaternary; löss; post-IR IRSL; Lowland Point; England; kvartär;

    Sammanfattning : Loess deposits are terrestrial clastic sediments derived from aeolian deposition. Loess is transported in periglacial conditions and was mainly deposited in cold environments around glaciers during the Quaternary period. LÄS MER

  7. 5. 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
