2000 years of annual ice core data from Law Dome, East Antarctica

Ice core records from Law Dome in East Antarctica collected over the last four decades provide highresolution data 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 from Law Dome covering the period from -1 to 2017 CE (1961 to -6 BP 1950) and the level-1 chemistry data from which the annual chemistry records are derived. Law Dome ice core records have been used extensively in studies of the past climate of the Southern Hemisphere and in large-scale data syntheses and reconstructions in a region where few records exist, especially at high temporal resolution. This dataset provides an update and extensions both forward and back in time of previously published subsets of the data, bringing them together into a coherent set with improved dating to enable continued use of this record. The data are available for download from the Australian Antarctic Data Centre at https://doi.org/10.26179/5zm0-v192 (Curran et al., 2021).

Automated summary

Ice core records from Law Dome in East Antarctica provide high-resolution data for studying climate in Antarctica, Australia, and the Southern and Indo-Pacific oceans. This dataset, which includes trace chemistry, stable water isotopes, and snow accumulation records, has been extensively used in climate research and data syntheses in the Southern Hemisphere. The data have been updated and extended, and are available for download.
