Stable isotope records of Arctic and Antarctic ice cores ...
Polar precipitation archived in ice caps contains information on past temperature conditions. Such information can be retrieved by measuring the water isotopic signals of ?18O and ?D in ice cores. These signals have been attenuated during densification due to molecular diffusion in the firn column,...

Polar precipitation archived in ice caps contains information on past temperature conditions. Such information can be retrieved by measuring the water isotopic signals of ?18O and ?D in ice cores. These signals have been attenuated during densification due to molecular diffusion in the firn column, where the magnitude of the diffusion is isotopologoue specific and temperature dependent. By utilizing the differential diffusion signal, dual isotope measurements of d18O and dD enable multiple temperature reconstruction techniques. This study assesses how well six different methods can be used to reconstruct past surface temperatures from the diffusion-based temperature proxies. Two of the methods are based on the single diffusion lengths of d18O and dD, three of the methods employ the differential diffusion signal, while the last uses the ratio between the single diffusion lengths.
