Excitation-Emission Matrix (EEM) and absorbance spectra for samples collected as part of the campaign detailed here:

A comprehensive set of measurements and calculated metrics describing physical, chemical, and biological conditions in the river corridor is presented. These data were collected in a catchment-wide, synoptic campaign in the H. J. Andrews Experimental Forest (Cascade Mountains, Oregon, USA) in summer 2016 during low-discharge conditions. Extensive characterization of 62 sites including surface water, hyporheic water, and streambed sediment was conducted spanning 1st- through 5th-order reaches in the river network. The objective of the sample design and data acquisition was to generate a novel data set to support scaling of river corridor processes across varying flows and morphologic forms present in a river network. The data are available at https://doi.org/10.4211/hs.f4484e0703f743c696c2e1f209abb842 (Ward, 2019).

本数据集包含为本项后文详述的野外调查采集的样品的激发发射矩阵（Excitation-Emission Matrix, EEM）与吸收光谱。

本研究呈现了一套完整的实测数据与计算指标，用以描述该河流廊道内的物理、化学与生物环境状态。这些数据采集于2016年夏季，地点为美国俄勒冈州喀斯喀特山脉的H. J. 安德鲁斯实验森林（H. J. Andrews Experimental Forest），是一次覆盖全流域的同步野外调查，采集时段处于低流量期。本次调查覆盖河网中1至5级河段，共对62个采样点位开展了详尽的表征工作，涉及地表水、底隙水与河床沉积物三类样品。本次采样设计与数据采集的核心目标是构建一套全新数据集，以支撑跨河网不同流量与地貌形态的河流廊道过程尺度转换研究。该数据集可通过以下链接获取：https://doi.org/10.4211/hs.f4484e0703f743c696c2e1f209abb842（Ward, 2019）。
