PoroTomo Natural Laboratory Horizontal and Vertical Distributed Acoustic Sensing Data

This dataset includes links to the PoroTomo DAS data in both SEG-Y and hdf5 (via h5py and HSDS with h5pyd) formats with tutorial notebooks for use. Data are hosted on Amazon Web Services (AWS) Simple Storage Service (S3) through the Open Energy Data Initiative (OEDI). Also included are links to the documentation for the dataset, a Jupyter Notebook tutorial for working with the data as it is stored in AWS S3, and links to data viewers in OEDI for the horizontal (DASH) and vertical (DASV) DAS datasets. Horizontal DAS (DASH) data collection began 3/8/16, paused, and then started again on 3/11/2016 and ended 3/26/2016 using zigzag trenched fiber optic cabels. Vertical DAS (DASV) data collection began 3/17/2016 and ended 3/28/16 using a fiber optic cable through the first 363 m of a vertical well. These are raw data files from the DAS deployment at (DASH) and below (DASV) the surface during testing at the PoroTomo Natural Laboratory at Brady Hot Spring in Nevada. SEG-Y and hdf5 files are stored in 30 second files organized into directories by day. The hdf5 files available via HSDS are stored in daily files. Metadata includes information on the timing of recording gaps and a file count is included that lists the number of files from each day of recording.

本数据集包含指向PoroTomo分布式声学传感（Distributed Acoustic Sensing，DAS）数据的链接，数据格式涵盖SEG-Y与hdf5（可通过h5py及HSDS搭配h5pyd访问），并配套使用教程笔记本。数据通过开放能源数据倡议（Open Energy Data Initiative，OEDI）托管于亚马逊云服务（Amazon Web Services，AWS）的简单存储服务（Simple Storage Service，S3）。
本数据集还包含数据集文档链接、用于处理AWS S3中存储格式数据的Jupyter Notebook教程，以及OEDI平台内针对水平分布式声学传感（Horizontal DAS，DASH）与垂直分布式声学传感（Vertical DAS，DASV）数据集的数据查看器链接。
水平DAS（DASH）数据采集始于2016年3月8日，曾暂停后于2016年3月11日重启，最终于2016年3月26日结束，采集过程使用了锯齿形敷设的光纤光缆。垂直DAS（DASV）数据采集始于2016年3月17日，结束于2016年3月28日，采用了贯穿垂直井筒前363米的光纤光缆。
这些数据为内华达州布雷迪温泉PoroTomo自然实验室测试期间，地表处（DASH）及地表以下（DASV）的DAS部署原始数据文件。
SEG-Y与hdf5文件均按30秒时长分片，并按日目录进行组织。通过HSDS访问的hdf5文件则按日存储。
元数据包含记录间隙的时序信息，同时附带文件计数列表，统计了每日采集的文件数量。
