  2. 21. 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. 22. Retreat pattern and dynamics of glaciers and ice sheets: reconstructions based on meltwater features

    Author : Martin Margold; Krister Jansson; Arjen Stroeven; Johan Kleman; Karin Helmens; Chris Stokes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoglaciology; Cordilleran Ice Sheet; deglaciation; glacial meltwater features; glacial lake; Physical Geography; naturgeografi;

    Abstract : Glaciers and ice sheets covered extensive areas in the Northern Hemisphere during the last glacial period. Subsequently to the Last Glacial Maximum (LGM), they retreated rapidly and, except for Greenland and some other ice caps and glaciers, they vanished after the last glacial termination. READ MORE

  5. 23. Mountain centered icefields in northern Scandinavia

    Author : Ola Fredin; Clas Hättestrand; Arjen Stroeven; Peter Jansson; Johan Kleman; Jon Landvik; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavia; Quaternary; Weichselian; mountain; icefield; ice sheet; Physical geography; Naturgeografi;

    Abstract : Mountain centered glaciers have played a major role throughout the last three million years in the Scandinavian mountains. The climatic extremes, like the present warm interglacial or cold glacial maxima, are very short-lived compared to the periods of intermediate climate conditions, characterized by the persistence of mountain based glaciers and ice fields of regional size.

  7. 25. Deglacial impact of the Scandinavian Ice Sheet on the North Atlantic climate system

    Author : Francesco Muschitiello; Barbara Wohlfarth; Raimund Muscheler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate; North Atlantic; last deglaciation; isotope geochemistry; chronology; climate modeling; Marine Geology; maringeologi;

    Abstract : The long warming transition from the Last Ice Age into the present Interglacial period, the last deglaciation, holds the key to our understanding of future abrupt climate change. In the last decades, a great effort has been put into deciphering the linkage between freshwater fluxes from melting ice sheets and rapid shifts in global ocean-atmospheric circulation that characterized this puzzling climate period.
