Distributed acoustic sensing spatiotemporal maps from Cape Muroto

This dataset contains the raw experimental data that were produced as part of the NERC-funded project with colleagues from JAMSTEC. The data contains around 1500 spatiotemporal maps / waterfall plots. These maps represent strain values obtained from two different Distributed Acoustic Sensing (DAS) devices attached to a subsea fibre optic cable at Cape Muroto in Japan. On the y-axis it is the spatial, while on the x-axis the temporal dimensions. A portion of this Dataset was processed and labelled in order to train a Convolutional Neural Network classifier. This is available in a different dataset: DOI https://doi.org/10.5258/SOTON/D2831本数据集包含由英国自然环境研究委员会（Natural Environment Research Council, NERC）资助，我方与日本海洋研究开发机构（Japan Agency for Marine-Earth Science and Technology, JAMSTEC）同仁共同开展的项目所产生的原始实验数据。数据集包含约1500张时空图谱/瀑布图，这些图谱表征了两种不同分布式声学传感（Distributed Acoustic Sensing, DAS）设备采集得到的应变值，上述设备部署于日本室户岬的海底光纤电缆上。该图谱的纵轴代表空间维度，横轴代表时间维度。本数据集的部分数据经过处理与标注，用于训练卷积神经网络（Convolutional Neural Network, CNN）分类器；相关处理后的数据集已发布于另一数据集，其DOI为https://doi.org/10.5258/SOTON/D2831
