Sodium and calcium data from the full Skytrain Ice Rise ice core

This dataset consists of sodium (Na) and calcium (Ca) data for the full length of the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The data were from water sampled continuously from the melt stream of a continuous flow analysis system and are presented at 20 cm resolution where data exist. The analysis method was inductively coupled mass spectrometry using an Agilent 7700x ICP-MS attached to the melt stream.
