The 2009 Young Scientist Outstanding Poster Paper (YSOPP) Award is awarded to Jakob Heyman for the poster/PICO entitled:
Constraining the glacial chronology of Bayan Har Shan, NE Tibetan Plateau – Cosmogenic exposure dating of boulders, surface pebbles/cobbles and sediment depth profiles (Heyman, J.; Stroeven, A.P.; Caffee, M. W.; Li, Y.; Harbor, J.; Hättestrand, C.; Alexanderson, H.; Zhou, L.)

Jakob is a PhD student at Stockholm University (Department of Physical Geography and Quaternary Geology) working on the paleoglaciology of the northeastern Tibetan Plateau. Remote sensing, field investigations and numerical dating techniques are used to arrive at a paleoglaciological reconstruction for the Bayan Har Shan, the source area of the Yellow River. The EGU poster 2009 presents cosmogenic Be-10 exposure ages from 66 glacial deposit samples which constrain the glacial chronology of central Bayan Har Shan. Three types of samples have been used: boulders, surface pebbles/cobbles and sediment depth profiles. The exposure ages range up to
c. 160 ka and indicate very restricted glaciation (glaciers <10 km long or absent) over the last 60 ka.
