McMurdo Dry Valleys Cation, Anion Concentrations Along Lake Sediment/Water Interface

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic aqueous geochemical sampling program has been undertaken. A series of water samples have been collected and analyzed for major ion chemistry by ion chromatography. The concentrations of ions cover a wide range of total dissolved solids from fresh to hypersaline lake waters. This dataset shows concentrations of lithium, sodium, potassium, magnesium, calcium, iron, chlorine, bromine, and SO4 found along the sediment/water interface of Taylor Valley lakes.作为南极洲麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）项目的组成部分，本研究已开展系统性水相地球化学采样工作。研究团队采集了一系列水样，并通过离子色谱法（ion chromatography）对其主要离子化学特征进行分析。水样离子浓度覆盖了从淡水至高盐湖水中的全范围总溶解固体浓度区间。本数据集收录了泰勒谷各湖泊沉积物-水界面处锂、钠、钾、镁、钙、铁、氯、溴及SO4的浓度数据。
