GAS EXTRACTION FROM POLAR ICE CORES: A CRITICAL ISSUE FOR STUDYING THE EVOLUTION OF ATMOSPHERIC C0 2 AND ICE-SHEET SURFACE ELEVATION by
International audience The measurement of gases enclosed in polar ice cores provides valuable Information concerning the history of the 1ce sheets and their environment. The extraction of gases from ice is a critical step in the experimental procedure. We found that the most efficient methods of gas...
