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