Sample water chemistry and dissolved organic matter composition data for streams in six Canadian ecozones

This dataset contains water chemistry (major ions, inorganic nutrients) and dissolved organic matter (DOM) composition data for 52 streams sampled in 2019-2021 at several research sites across Canada. DOM composition was analyzed using UV-vis absorbance and fluorescence, Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), and asymmetric flow field-flow fractionation (AF4).

本数据集涵盖2019至2021年，于加拿大境内多个研究站点采集的52条溪流的水化学（主要离子、无机营养盐）及溶解性有机质（Dissolved Organic Matter, DOM）组成数据。其中溶解性有机质组成通过紫外-可见吸收光谱、荧光光谱、傅里叶变换离子回旋共振质谱（Fourier-transform ion cyclotron resonance mass spectrometry, FT-ICR-MS）与不对称流场流分级分离（asymmetric flow field-flow fractionation, AF4）技术完成分析。
