The dataset contains continuous waveforms from a two-week Distributed Acoustic Sensing (DAS) experiment and the resulting catalog(s). The DAS data were recorded along a ~15 km-long dark telecom optical fiber connecting the villages of Antipata (Kefalonia) and Stavros (Ithaki), Greece. Continuous waveforms cover the period from 1 August 2024, 23:00 UTC to 15 August 2024, 23:00 UTC, with a short data gap between 09:14 and 09:48 UTC on 6 August 2024 due to an archiving interruption. File names correspond to UTC time + 1 hour, following the default system convention. Data acquisition was performed using a QuantX OptaSense interrogator with a ping rate of 5000 Hz, and subsequently decimated by a factor of 20 to a final sampling rate of 250 Hz. The system configuration used a gauge length of 10 m and a channel spacing of 2.04 m, resulting in a total of 7,750 channels. Waveform data are stored in 30-second segments and in the default instrument unit (optical phase shift). Additionally, we include the channel list after removing loops. and The DOWNLOAD ALL button provides a bash script that downloads all files in this dataset using a sequence of 'curl' commands. You may edit the script to suit your needs—for example, by removing or commenting out 'curl' lines corresponding to files or time intervals you do not wish to download.
