Interpreting temperature information from ice cores along the Antarctic Peninsula: ERA40 analysis
suggests that annual mean isotopic fluctuations due to temperature change will be geographically very variable across the Peninsula: isotopic variations of 0.4 % at James Ross Island; 0.9 % at Dyer; and 1.3 % at Gomez are all likely to indicate an identical magnitude of temperature change.
