Antarctic temperatures over the past two centuries from ice cores
[1] We present a reconstruction of Antarctic mean surface temperatures over the past two centuries based on water stable isotope records from high-resolution, precisely dated ice cores. Both instrumental and reconstructed temperatures indicate large interannual to decadal scale variability, with the dominant pattern being anti-phase anomalies between the main Antarctic continent and the Antarct...

متن کاملInferring accumulation records from ice-cores
Ice cores contain a record of snow precipitation that includes information about past atmospheric circulation and mass imbalance in the polar regions. We present a novel adjoint method to reconstruct a climatic record by both optimally dating an ice-core and deriving from it a detailed accumulation history. The motivation of our work is the 5 recent application of phase sensitive radar which me...
متن کاملInterpreting temperature information from ice cores along the Antarctic Peninsula: ERA40 analysis
[1] Analysis of ERA40 temperature and accumulation data 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. The reduction in the magnitude of the isotopic signal...
