Silverado California Thermoluminescence Data

This dataset represents thermoluminescence (TL) data that was obtained after a series of experiments to investigate how TL techniques can indicate the depth of soil heating. This project was attempted to ultimately predict changes in erosion properties in burned areas subject to debris flow hazards. The soil samples were obtained from an area burned by the Silverado wildfire (September 12 to 20, 2014). The dataset includes 3 soil samples and 1 control sample. The three burned soil samples were obtained throughout the burned watershed, and the control sample was taken in an unburned area. These will be referred to as sample 3, sample 7, sample 10, and control 1. All soil was obtained on April 23, 2015. The sample cores were slotted into 2-cm partitions up to a maximum depth of 14 cm in order to allow laboratory subsampling of the core in depth increments. For each sample, the tube had 7 subsections and we extracted at least 4 replicates for each subsection. For example, Sample 10-1a is the first replicate for the first subsample, and 10-1b is the second replicate for the first subsample. Using the silt fraction in each of the seven 2-cm segments, we performed several laboratory experiments. The files attached are thermoluminescence data from the Risø TL/OSL Reader (model TL/OSL–DA–20). Each file has 3 columns, where column 1 represents an ID, column 2 represents a heat applied by the TL/OSL Reader, and column 3 represents the TL counts. The file names connote the sample, soil depth, subsample, and irradiation (yes/no) using the following naming convention: SampleNumber-Depth_Temperature(IRRADIATED if the sample was irradiated)SubsampleLetter.txt.本数据集为一系列实验所得的热释光（thermoluminescence, TL）数据，旨在探究热释光技术如何指示土壤受热深度，本研究的最终目标是预测受泥石流灾害威胁的火烧区域的侵蚀特性变化。土壤样本采自2014年9月12日至20日发生的西尔韦拉多（Silverado）野火的过火区域，本数据集包含3份过火土壤样本与1份对照样本：3份过火土壤样本采集自过火流域的不同区域，对照样本取自未过火区域，分别记为样本3、样本7、样本10与对照1。所有土壤样品均于2015年4月23日采集。将样品岩芯按2厘米为间隔进行分区，最大深度达14厘米，以便实验室按深度梯度对岩芯进行子采样。每份样品的采样管共分为7个子区域，且每个子区域至少提取4份重复样品。例如，Sample 10-1a代表第1个子区域的第1份重复样品，10-1b则代表该子区域的第2份重复样品。针对7个2厘米分段中的粉粒组分，我们开展了多组实验室实验。附件中的文件为Risø TL/OSL读数仪（型号TL/OSL–DA–20）测得的热释光数据。每个文件包含3列数据：第1列为ID，第2列为TL/OSL读数仪施加的加热量，第3列为热释光计数。文件名遵循以下命名约定，以标注样品、土壤深度、子样本与辐照状态（是否经过辐照）：SampleNumber-Depth_Temperature(若样品经辐照则标注IRRADIATED)SubsampleLetter.txt。
