    Sammanfattning : 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. LÄS MER

  3. 2. Comparison of dating methods for paleoglacial reconstruction in Central Asia

    Författare :Natacha Gribenski; Krister N. Jansson; Arjen P. Stroeven; Frank Preusser; Jonathan M. Harbor; Marc Bateman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciation; Optically stimulated luminescence dating; Cosmogenic nuclide exposure dating; EMCCD camera; Physical Geography; naturgeografi;

    Sammanfattning : Reconstruction of former Central Asian glaciers extents can provide valuable information about past atmospheric circulation variations. These extents, often marked by terminal moraines, need to be chronologically constrained. Cosmogenic nuclide exposure (CNE) dating is widely used to directly date moraines. LÄS MER
