  2. 11. On the interaction between ice sheets and the large-scale atmospheric circulation over the last glacial cycle

    Author : Marcus Löfverström; Rodrigo Caballero; Johan Nilsson; David Battisti; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric stationary waves; coupled atmosphere-ice sheet modelling; stationary wave-ice sheet interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The last glacial cycle (c. 115-12 kyr BP) was the most recent in a series of recurring glaciations of the subpolar continents. Massive ice sheets evolved in Eurasia and North America, which, at their maximum, were of continental scale and together lowered the global sea-level by approximately 100 m. READ MORE

  4. 12. Improvements for IceCube Event Reconstruction through Geometry Calibration and Photon Timing Distributions

    Author : Matti Jansson; Klas Hultqvist; Chad Findley; Aart Heijboer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Large detector systems for particle and astroparticle physics; Neutrino detectors; Splines; Maximum likelihood; Physics; fysik;

    Abstract : The origin of high-energy cosmic rays is an unsolved mystery because cosmic rays do not travel in a straight line but are bent by magnetic fields due to their electric charge. High energy neutrinos are predicted to be created close to these origins, and are an unambiguous probe, while gamma rays could be obscured or created by other processes. READ MORE

  5. 13. Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach

    Author : Johan Striberger; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Iceland; the Holocene; lake sediments; varves; glacial meltwater variability; surge periodicity; palaeoclimate;

    Abstract : The North Atlantic region has experienced significant climate fluctuations during the Holocene. It has been shown that these fluctuations affected the terrestrial environment in Iceland, including its glaciers and ice caps. READ MORE

  6. 14. Paleoglaciology of the Tian Shan and Altai Mountains, Central Asia

    Author : Robin Blomdin; Arjen P. Stroeven; Clas Hättestrand; Jonathan M. Harbor; Lewis Owen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; glacial geomorphological mapping; cosmogenic nuclide dating; Tian Shan; Altai Mountains; Physical Geography; naturgeografi;

    Abstract : The mountain-systems of Central Asia, act as barriers to atmospheric circulation patterns, which in turn impose striking climate gradients across the region. Glaciers are sensitive indicators of climate change and respond to changes in climate gradients over time by advancing during cold and wet periods and receding during warm and dry periods. READ MORE

  7. 15. Uncovering the Past through ancient DNA : The Fate and Legacy of the last hunter-gatherers in Western Europe and Northwestern Africa

    Author : Luciana G. Simões; Mattias Jakobsson; Torsten Günther; Cristina Valdiosera; Emma Svensson; Martin Sikora; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human evolution; archaeogenomics; ancient DNA; population genetics; hunter-gatherer; Populationsbiologi; Population Biology; Genetik; Genetics;

    Abstract : The genetic analysis of ancient human remains has revolutionized the study of human history, opening a direct window onto the demographic and evolutionary events that shaped our species' past. I use state-of-the-art ancient DNA methodologies, from sample collection and DNA extraction to data analysis, to study the ancient past of the western Mediterranean region, where climate does not favour DNA preservation.
