Complementary Geochemical, mineralogical and microbiological analyses of materials collected on the Greenland Ice Sheet

This dataset comprises of geochemical, mineralogical and microbiological analyses of material collected on the southwestern margin of the Greenland Ice Sheet in 2016 and 2017. Stream water, melted ice and snow samples were collected and analysed for carbon, nitrogen, phosphorus, cation and anion concentrations, pH, conductivity, total dissolved solids (TDS), mineral phase and class abundances and Rare Earth Elements (REE). Microbial community composition was also analysed. In addition, the results of a nutrient incubation experiment are also presented.The data were collected as part of a project investigating drivers of glacial ice algal growth on the Greenland Ice Sheet.

本数据集包含2016年与2017年在格陵兰冰盖西南缘采集样品的地球化学、矿物学及微生物学分析数据。研究人员采集了河水、融冰及积雪样品，对其中的碳、氮、磷、阴阳离子浓度、pH值、电导率、总溶解固体（Total Dissolved Solids, TDS）、矿物相及类别丰度，以及稀土元素（Rare Earth Elements, REE）开展了分析测试。同时对微生物群落组成进行了分析。此外，本数据集还包含养分培养实验的结果。这些数据源自一项探究格陵兰冰盖冰川冰藻生长驱动因子的研究项目。
