Oxygen concentrations in sediment around buried oil quantified in a laboratory flume using oxygen-sensitive planar optodes

Oxygen concentration data from a flume experiment conducted on 26 November 2012. Quantitative interpretation of planar oxygen optode images was done using VisiSens AnalytiCal 1 software. The color coding reflects different oxygen concentrations. Blue colors are low oxygen, red and yellow high oxygen (black=no oxygen, white=100% airsaturation). Oxygen concentration data were calculated by VisiSens AnalytiCal 1 software from the calibrated planar optodes. The folders contain VisiSens oxygen sensing camera images positioned at 5 cm distances along the sidewall of the laboratory flume incubating sediment with tar balls, on 26-November 2012, at times: 8:33 when flow in the flume was initiated, 10:45 when flow continued, 15:11 when flow continued to oxygenate the sediment, 15:46 when flow was stopped in order to initiate oxygen depletion, 18:00 after deoxygenation of the sediment. Data include the calibrated oxygen pictures and associated folders with tables containing the calibrated values from the color coded oxygen pictures. The tables have 928 columns and 742 rows with each cell corresponding to one pixel on the associated image. An Excel "read me" file is provided that explains how the text file associated with each of the oxygen distribution pictures should be read. This Excel file can be used as a template for importing the txt files with the oxygen data. This dataset was submitted as RFP I Deep-C dataset R1.x138.078:0030.本数据集为2012年11月26日水槽实验获取的氧气浓度数据。研究人员使用VisiSens AnalytiCal 1软件对平面氧光极（planar oxygen optode）图像开展定量解译，通过颜色编码表征不同氧气浓度：蓝色代表低氧环境，红色与黄色代表高氧环境（黑色代表无氧气，白色代表100%空气饱和度）。 氧气浓度数据由VisiSens AnalytiCal 1软件基于校准后的平面氧光极计算得到。各文件夹内存储VisiSens氧传感相机拍摄的图像，拍摄时相机沿孵化有焦油球沉积物的实验室水槽侧壁以5厘米间距布置，拍摄时间节点分别为：2012年11月26日8:33（水槽启动水流时刻）、10:45（维持水流状态时刻）、15:11（持续水流以对沉积物充氧时刻）、15:46（停止水流以启动氧气消耗过程时刻）、18:00（沉积物脱氧完成后时刻）。 数据集包含校准后的氧气分布图，以及配套的表格文件夹，其中表格存储了颜色编码氧气图像对应的校准数值。每张表格包含928列与742行，每个单元格对应关联图像上的一个像素。 此外附带一份Excel"自述"文件，用于说明如何读取每张氧气分布图像对应的文本文件，该Excel文件可作为导入氧气数据文本文件的模板。 本数据集以RFP I Deep-C数据集R1.x138.078:0030编号提交。
