  1. 1. 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

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

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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.

  4. 3. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanna Andersson; [2021]
    Nyckelord :geochemistry; loess; XRF; weathering; climate change; N-W France;

    Sammanfattning : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. LÄS MER

  5. 4. Stratigrafin i Hanöbukten under senaste glaciationen : en studie av borrkärnor från IODP’s expedition nr 347

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Gisela Åberg; [2014]
    Nyckelord :ice-rafted debris; lervarvskronologi; Bølling; IODP; Hanöbukten; Östersjön; Earth and Environmental Sciences;

    Sammanfattning : The development of Hanö Bay during the last ice age has been investigated by analyzing cores from IODP’s Balitc Sea Palaeoenvironment expedition in the Baltic Sea. By analyzing the presence of Ice Rafted Debris, correlating one of the varved clay units to Ringbergs (1991)regional varve chronology from southeastern Sweden, analyzing pollen grains and measuring loss on ignition a few gaps in the history of Hanö Bay has been uncovered.

  7. 5. Borrning efter interstadiala sediment vid Ultevisplatån, Norrbotten

    Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Stefan Bjursäter; [2013]
    Nyckelord :Ultevis; Interstadial; Weichsel; IRSL-measurments; Northern Sweden; Norrbotten; Glacial history; Ultevis; interstadial; Weichsel; IRSL-mätningar; norra Sverige; Norrbotten; istidshistoria;

    Sammanfattning : The purpose of this study is to find datable interstadial sediments in the core area of the LateWeicheslian ice sheet extent. Based on geomorphological evidence, three coring sites wereidentified close to the Ultevis plateau in Norrbotten, northern Sweden. LÄS MER
