MBS2023 - The Mount Brown South Main ice core chronology and data and surface core chronologies, Ver. 1 Tessa R. Vance et al. https://doi.org/10.26179/352b-6298
Short summary
This study presents the chronologies from the new Mount Brown South ice cores from East Antarctica, which were developed by counting annual layers in the ice core data and aligning these to volcanic sulfate signatures. The uncertainty in the dating is quantified, and we discuss initial results from seasonal cycle analysis and mean annual concentrations. The chronologies will underpin the development of new proxy records for East Antarctica spanning the past millennium.
