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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  3. 2. High Sampling Resolution Luminescence Dating of Loess in Brittany, France

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Vanda Jakabová; [2021]
    Keywords : aeolian dust; loess; luminescence; dMAR; Brittany; LGM; palaeoenvironment; eoliskt damm; loess flygmo ; luminescens; dMAR; Bretagne; LGM; paleomiljö;

    Abstract : Aeolian dust is an important but poorly understood component of the climate system, which both responds to and drives global climate. Recently, dust produced at the high latitudes is also gaining attention as a possible contributor to the atmospheric dust load. READ MORE

  4. 3. Rock-magnetic and Soil Organic Carbon Proxies of Climate Change from Loess – Aeolian Sediments of Brittany, France

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Carolina Kouns; Yael Margulis; [2021]
    Keywords : loess; LOI; magnetic susceptibility; Brittany; Quaternary; löss; LOI; magnetisk susceptibilitet; Bretagne; kvartär;

    Abstract : The aeolian sediment loess, which consists of mineral dust, is one of the most detailed terrestrial record of both global and regional climate changes. As climate changes in the past cover a much wider range of climate variability than humans have directly recorded, the soil memory of loess is vital for understanding the Earth’s climate system.

  5. 4. Investigating the Magnetic Susceptibility of Cornish Loess as a Tool for Understanding the Palaeoclimate of SW England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Love Tingdal; [2020]
    Keywords : loess; palaeoclimate; Lizard Peninsula; Isles of Scilly; palaeoprecipitation; magnetic susceptibility; loess; paleoklimat; Lizard-halvön; Scillyöarna; historisk årsmedelnederbörd; magnetisk susceptibilitet;

    Abstract : Loess is a silty material produced via glacial grinding and its deposition is usually associated with colder periods when there is a considerable increase in atmospheric dust transport. The magnetic susceptibility of loess-palaeosol sequences has been the subject of extensive research within palaeoclimatology as it has proven to be reliable climate proxy. READ MORE

  6. 5. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Isabelle Karnik; [2019]
    Keywords : loess; XRF; weathering index; Holocene climate; Greenland;

    Abstract : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. READ MORE
