Optode Images, and Dissolved Oxygen Data from Sand and Sediment Flow-through Column Experiments associated with: "2-D Imaging of Dissolved Oxygen Concentration in Flow-Through Sediment Columns"

This data package is associated with the publication "2-D Imaging of Dissolved Oxygen Concentration in Flow-Through Sediment Columns" submitted to Frontiers in Water (Garayburu-Caruso et al., 2022). This work presents a novel application of planar optode technology to sediment columns that allows the study of well-constrained flow fields without the need to assume completely homogeneous flow. We introduce a flow-through column with the interior coated in an oxygen sensing film and a series of sampling ports as a unique tool capable of capturing changes in dissolved oxygen (DO) at high frequency (10 s) and spatial (< 1 mm) resolution across the length of a column. In addition, we provide custom scripts that allows image processing steps to be automated and consistently reproduced over a variety of experimental conditions. This dataset is comprised of four folders (1) 01_Riverbed_Sediment_Experiment, (2) 02_Sand_Experiment, (3) 01_Riverbed_Sediment_Raw_Images, and (4) 02_Sand_Experiment_Raw_Images. 01_Riverbed_Sediment_Experiment contains (1) a subfolder with csv files that contain statistical parameters from the linear regressions applied to each optode image, (2) a subfolder with csv files from DO data measured by in-line sensors, (3) a subfolder with csv files containing column and injection specific input parameters for the image processing script, and (4) a subfolder with scripts used to process the images and create associated figures. 02_Sand_Experiment contains (1) a subfolder with csv files containing column and injection-specific input parameters for the image processing script, and (2) a subfolder with scripts used to process the images and create associated figures. 01_Riverbed_Sediment_Raw_Images (spited in 3 parts due to size) contains a subfolder with raw red, and green images from the optode system during the MilliQ Injection, Vanillin Injection or Vanillin + Sampling Injection respectively. 02_Sand_Experiment_Raw_Images contains a subfolder with raw red, and green images from the optode system. Outside of the main folders there is a csv containing file-level metadata and a csv data dictionary defining column headers for all csv files contained in the data package.本数据包关联发表于《水前沿》（Frontiers in Water）的论文《流通式沉积物柱体中溶解氧浓度的二维成像》（Garayburu-Caruso等人，2022）。本研究将平面光极（planar optode）技术创新性地应用于沉积物柱体，可在无需假设流动完全均匀的前提下，研究约束良好的流场。我们设计了一款内壁涂覆氧传感膜、带有一系列采样端口的流通式柱体，作为一款可在柱体全长范围内，以10秒的高时间频率与<1毫米的空间分辨率捕获溶解氧（DO，Dissolved Oxygen）变化的专属工具。此外，我们提供了自定义脚本，可实现图像处理步骤的自动化，并在多种实验条件下实现结果的一致复现。本数据集包含四个文件夹：(1) 01_Riverbed_Sediment_Experiment、(2) 02_Sand_Experiment、(3) 01_Riverbed_Sediment_Raw_Images 以及 (4) 02_Sand_Experiment_Raw_Images。01_Riverbed_Sediment_Experiment 包含四个子文件夹：(1) 存储对每个平面光极图像进行线性回归分析所得统计参数的逗号分隔值（CSV）文件；(2) 存储在线传感器测得的溶解氧数据的CSV文件；(3) 存储图像处理脚本所需的柱体与进样专属输入参数的CSV文件；(4) 用于图像处理并生成相关图表的脚本文件。02_Sand_Experiment 包含两个子文件夹：(1) 存储图像处理脚本所需的柱体与进样专属输入参数的CSV文件；(2) 用于图像处理并生成相关图表的脚本文件。01_Riverbed_Sediment_Raw_Images（因体积较大分为3个部分）包含一个子文件夹，内含分别在超纯水（MilliQ）进样、香草醛进样或香草醛+采样进样期间，平面光极系统采集到的原始红色与绿色图像。02_Sand_Experiment_Raw_Images 包含一个子文件夹，内含平面光极系统采集到的原始红色与绿色图像。在主文件夹之外，还有一份存储文件级元数据的CSV文件，以及一份用于定义本数据包内所有CSV文件列标题的数据字典CSV文件。
