Abstract:

This dataset consists of water isotope data (δ18O and δD) for the entire 651 m from the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The top 2.83 m are from a snowpit. Remaining data in doi:10.1594/PANGAEA.973166 are from water sampled continuously from the melt stream of a continuous flow analysis (CFA) system (data labelled as CFA), and are presented at 20 cm resolution where data exist. Discrete samples (see doi:10.1594/PANGAEA.973167) were also taken both as a check, and in areas where the CFA data are missing; these data are suitable for calculating deuterium excess. Data were measured using a Picarro L2130-i cavity ringdown spectrometer. Note the that top 418 m have previously been archived at 10 cm resolution (as doi:10.1594/PANGAEA.966226)
