Sodium data for last 10 ka from Skytrain Ice Rise ice core

This dataset consists of sodium (Na) data 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 data were from water sampled continuously from the melt stream of a continuous flow analysis system and are presented at 10 cm resolution where data exist. The analysis method was inductively coupled mass spectrometry using an Agilent 7700x ICP-MS attached to the melt stream.

本数据集涵盖南极斯凯通冰隆（Skytrain Ice Rise，79.7417°S 78.545°W）2018-2019年钻取的冰芯顶部418米的钠（Na）数据，其时间序列可回溯至距今10千年（kyr before present）。数据取自连续流分析系统融水流道的连续采样水样，在存在有效数据的区间以10厘米的分辨率给出。分析方法采用安装于融水流道的安捷伦7700x型电感耦合等离子体质谱仪（ICP-MS）。
