Linking Antarctic glaciochemical records to past climate conditions (scientific paper)

元データ 国立極地研究所

概要

Deep Antarctic ice cores document the former states of the climatic system, the atmosphere, and the marine and terrestrial biospheres. However, questions do remain in the interpretation and the reliability of ice core chemical profiles in terms of atmospheric information. Data from the Dome C, Vostok, Dome F, and EPICA deep ice cores are used and compared in the discussions. First of all, the transfer functions of various gaseous and particulate compounds are not entirely understood and in the case of acid gases, strong post-deposition effects are observed at central Antarctic sites. It is emphasised that marine primary and secondary aerosol species may strongly interact during their long-range transport. Continental aerosol is important for the Antarctic impurity budget only in glacial environmental conditions. Its composition, as derived from Antarctic ice core glaciochemistry is discussed. As for the case of marine aerosol, the reaction of primary and gas-derived aerosol has to be considered. Finally, the possible impact of continental dust on marine biogenic activity shortly is discussed in the light of glaciochemical results.
