WebInterpolation methods for Antarctic ice-core timescales: application to Byrd, Siple Dome and Law Dome ice cores. Abstract. Antarctic ice cores have often been dated by matching distinctive features of atmospheric methane to those detected in annually dated ice cores from Greenland. Establishing the timescale…. WebWe thus propose to use the δ18Ocalcite as target for δ18Oatm orbital dating. Such a tuning method improves the ice core chronology of the last glacial inception compared to …

Web2004). Since absolute dating techniques for deep Antarctic ice cores are not available so far, climatic interpretations of ice core records are deeply dependent on the accuracy of ice flow models to relate the depth of ice to its age. Thus, a better understanding of ice rheology is at the root of ice core dating improvement. WebDeep ice core chronologies have been improved over the past years through the addition of new age constraints. However, dating methods are still associated with large uncertainties for ice cores from the East Antarctic plateau where layer counting is not possible. Indeed, an uncertainty up to 6 ka is associated with AICC2012 chronology of tshirt black front back
