Analyses of major solutes of moderately acidic hot spring waters and carbon, nitrogen, and pigment compositions of associated biofilms from Yellowstone National Park

This dataset contains temperatures, pH values, conductivities, stable water isotope ratios, and major solute concentrations for 14 water samples collected from 12 moderately acidic hot springs in Yellowstone National Park, Wyoming, United States. Charge imbalance calculations, pH values calculated based on charge balance, and DIC speciation are also included. Additionally, semi-quantitative abundances for various pigments (chlorophylls, their degradation products, and carotenoids) and bulk carbon and nitrogen contents of the associated biofilms/sediments are also included. Quantitative abundances normalized to total nitrogen in the biofilms/sediments are provided for chlorophyll a, β-carotene, β-cryptoxanthin, and zeaxanthin. Ribosomal gene sequence abundances for Bacteria and Eukarya are also provided.

本数据集包含美国怀俄明州黄石国家公园12处中度酸性热泉采集的14份水样的温度、pH值、电导率、稳定水同位素比值及主要溶质浓度。此外还涵盖电荷失衡计算结果、基于电荷平衡推导的pH值，以及溶解无机碳（Dissolved Inorganic Carbon, DIC）的形态分布数据。同时，数据集收录了各类色素（叶绿素及其降解产物、类胡萝卜素）的半定量丰度，以及相关生物膜/沉积物的总碳、总氮含量；针对叶绿素a、β-胡萝卜素、β-隐黄质与玉米黄质，还提供了以生物膜/沉积物总氮为基准的归一化定量丰度。另外，数据集也包含了细菌（Bacteria）与真核生物（Eukarya）的核糖体基因序列丰度数据。
