Limnological Chemistry, Ion Concentrations and Silicon

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 terrestrial 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, chloride,
bromide, silicon, fluoride, SO4, and dissolved inorganic carbon found in various depths
of Taylor Valley lakes.

作为南极洲麦克默多干谷（McMurdo Dry Valleys）长期生态研究（Long Term Ecological Research, LTER）项目的组成部分，本研究已启动系统性水相地球化学采样计划。研究团队采集了一系列陆地水体样本，并通过离子色谱法（ion chromatography）对其主要离子化学特征进行了分析。所涉离子的浓度覆盖了从淡水到高盐湖水体的宽泛总溶解固体（total dissolved solids）范围。本数据集包含泰勒谷（Taylor Valley）不同深度湖泊中锂、钠、钾、镁、钙、氯、溴、硅、氟、SO4以及溶解无机碳（dissolved inorganic carbon）的浓度数据。
