Description
Summary:Ice core records from Law Dome in East Antarctica collected over the last four decades provide highresolutiondata for studies of the climate of Antarctica, Australia, and the Southern and Indo-Pacific oceans. Here,we present a set of annually dated records of trace chemistry, stable water isotopes and snow accumulation fromLaw Dome covering the period from ????11 to 2017 CE (1961 to ????66 BP 1950) and the level-1 chemistry datafrom which the annual chemistry records are derived. Law Dome ice core records have been used extensivelyin studies of the past climate of the Southern Hemisphere and in large-scale data syntheses and reconstructionsin a region where few records exist, especially at high temporal resolution. This dataset provides an update andextensions both forward and back in time of previously published subsets of the data, bringing them together intoa coherent set with improved dating to enable continued use of this record. The data are available for downloadfrom the Australian Antarctic Data Centre at https://doi.org/10.26179/5zm0-v192 (Curran et al., 2021).
