CL Climate: Past, Present & Future
The 2011 Outstanding Student Poster (OSP) Award is awarded to Bernhard Bereiter for the poster/PICO entitled:
Atmospheric CO2 during the last glaciation and its implications for changes in the carbon cycle (Bereiter, B.; Lüthi, D.; Siegrist, M.; Schüpbach, S.; Stocker, T. F.; Fischer, H.)

Bernhard Bereiter is a PhD student at the Institute for Climate- and Environmental Physics and Oeschger Centre for Climate Change Research of the University of Bern, Switzerland. He is supervised by Thomas F. Stocker and works with polar ice cores used to reconstruct the past climate. His main focus are reconstructions of atmospheric CO2 concentrations during glacial-interglacial as well as millennial-scale climate variations. Further research interests are changes of gas inclusions in ice cores. In his poster he presents highly-resolved CO2 data for the period of the last glacial interception and shows that CO2 variations associated with millennial-scale climate variations from the early part of the record are distinct from the ones of the later part, indicating further influence of ocean circulation changes on CO2.
