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

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

  3. 2. 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

  4. 3. I jordbrukets periferi : En studie om utvecklingen av agrar bebyggelse i marginella miljöer från stenåldern till järnåldern i Norra Sverige

    Master-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

    Författare :Love Eriksson; [2019]
    Nyckelord :Norrland; Northern Sweden; Neolithization; Early agriculture; Stone Age; Neolithic period; Bronze Age; Late Iron Age; Norrland; Sverige; Jordbruk; Stenåldern; Bronsåldern; Järnåldern; Neolitisering;

    Sammanfattning : The development and establishment of agriculture in Northern Sweden has since long been believed to appear during the Late Iron Age, close to the Viking period, but recent finds from the Bronze Age in Umeå has opened up new discussion of when agriculture first emerged. Although too early to discuss where and when it developed, the material currently available on the topic allows for discussion for how it developed. LÄS MER

  5. 4. Optically Stimulated Luminescence (OSL) dating of aeolian sediments of Skåne, south Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Rajendra Shrestha; [2013]
    Nyckelord :Vomb basin; South Sweden; Skåne; Aeolian; Sediments; Grain size; Luminescence; OSL; Chronology; Earth and Environmental Sciences;

    Sammanfattning : Wind is an important agent of transportation of sediments and to change the landscape. Aeolian sediments can be inferred as a proxy for past climate. In Sweden aeolian sediments are not widespread and there are not so many studies on chronological and paleoenvironmental aspects. LÄS MER

  7. 5. Late holocene dune activity at Sandhammaren, southern Sweden : chronology and the role of climate, vegetation, and human impact

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Lovisa Zillén; [1998]
    Nyckelord :geography; geology; Late Holocene; dune activity; Sandhammaren; Sweden; chronology; climate; vegetation; human impact; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: De begravda jordmånsbildningarna vid Sandhammaren och Skanörs ljung, södra Sverige, är lokaliserade inom kustnära dynlandskap som har bildas i response till land-och havsnivåförändringar efter den sista istiden (efter ca. 10 000 år sedan).
