  1. 1. En resa tillbaka i tiden för att förstå framtiden : En undersökning av organiskt material i eoliska lössjordssediment på västra Grönland, Kangerlussuaq.

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Caroline Morin; Jessica Sundman; [2021]
    Nyckelord :Greenland; organic carbon; loss of ignition; loess; paleoclimate; Grönland; organiskt material; loss of ignition; lössjordar; paleoklimat;

    Sammanfattning : Today's changing climate on Earth makes climate research more important than ever. By providing an understanding of the Earth's history and in particular places where large-scale climate change is taking place, for example Greenland, can one get an understanding about how the Earth will react in the future.

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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isabelle Karnik; [2019]
    Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

    Sammanfattning : 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. LÄS MER

  5. 4. Arctic Loess as an Environmental Archive: Holocene Dust and Wildfire Record in West Greenland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lars Petter Hällberg; [2018]
    Nyckelord :aeolian dust; IRSL; luminescence dating; charcoal analysis; magnetic susceptibility; wildfire;

    Sammanfattning : The largest wildfire ever observed in Greenland raged through its tundra during august 2017, and it is unknown if there have been similar wildfires in the area before satellite monitoring began in 1999. Arctic wildfires affect permafrost degradation, carbon storage of soils and the surface albedo of the Greenland Ice sheet – despite this, local fires have previously been ignored by researchers.

  7. 5. Radiogenic Dating and Microstructure Analysis of Shear Zones Found Within the Seve Nappe Complex in the Åre Region, Jämtland, Scandinavian Caledonides

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Cameron Alessandrini; [2017]
    Nyckelord :Rb-Sr dating; Ar-Ar dating; Lower Seve Nappe; Scandinavian Caledonides; COSC drillhole.; Rb-Sr datering; Ar-Ar datering; Seveskollan; skandinaviska Kaledoniderna; vit glimmer; COSC borrkärna.;

    Sammanfattning : The North Atlantic Caledonides are a continent-continent collision type orogeny found in WesternScandinavia, Svalbard, Greenland and the British Isles. They are thought to have formed as a result of a complex history consisting of repeated ocean opening and closure. LÄS MER
