  1. 1. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Rognås; [2023]
    Keywords : aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Abstract : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. READ MORE

  3. 2. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

  6. 5. Investigation into the Loess-Palaeosol and Red Clay Record from the Pliocene- Quaternary Chinese Loess Plateau Using In-Phase and Out-OfPhase Magnetic Susceptibility

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Rebecca Jacobson; [2018]
    Keywords : loess; Chinese Loess Plateau; magnetic susceptibility; out-of-phase; viscous relaxation; lössjord; Kinesiska Lössjordsplatån; magnetiska känsligheter; ur-fas; viskös relaxation;

    Abstract : Loess is a well sorted, fine grained, windblown (aeolian) sediment and deposits as a blanket over large areas, reaching from a few centimetres to several hundreds of meters in height and can drape large landscapes in form of mountains. During a more humid and warmer climate, redox conditions are changed in the loess deposits, with greater seasonal moisture creating greater soil formation (pedogenesis), i. READ MORE
