  1. 1. 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

  3. 2. 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

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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.

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Cameron Alessandrini; [2017]
    Keywords : 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.;

    Abstract : 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. READ MORE

  6. 5. Methane flux measurements with low-cost solid state sensors in Kobbefjord, West Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Axén; [2016]
    Keywords : Geography; Physical Geography; Arctic; Greenland; methane flux; wetlands; instrument; Earth and Environmental Sciences;

    Abstract : Methane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. READ MORE
