Abstract:
This dataset consists of water isotope data (δ¹⁸O and δD) for the top 418 m (back to 10 kyr before present) 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. Most remaining data were from water sampled continuously from the melt stream of a continuous flow analysis system (data labelled as CFA), and are presented at 10 cm resolution where data exist. Discrete samples were also taken as a check, and in areas where the CFA data are missing; these data are labelled discrete. Data were measured using a Picarro L2130-i cavity ringdown spectrometer.
