The IPCC 5th Assessment Report states that there are insufficient Southern Hemisphere climate records to adequately assess climate change in much of this region. Ice cores provide excellent archives of past climate, as they contain a rich record of past environmental tracers archived in trapped air and precipitation. However Antarctic ice cores, especially those from East Antarctica, are limited in quantity and spatial coverage. To help address this, a 120 m ice core was drilled on Mill Island, East Antarctica (65¬¨‚àû 30' S, 100¬¨‚àû 40' E). Mill Island is one of the most northerly ice coring sites in East Antarctica, and is located in a region with sparse ice core data. The specific project aims were: 1) To produce a high resolution, welldated record of water stable isotopes (˜í¬•18O, ˜í¬•D), and trace ion chemistry (sea salts, sulphate, methanesulphonic acid); 2) to investigate the seasonal and interannual variability of sea salts, in order to reveal which climate factors influence the Mill Island record; ...
