The data for a beach-deployed fiber-optic DAS array in Sizihwan, Kaohsiung, Taiwan

DAS data acquired from 12 Nov 2024 12:48:00 UTC to 12 Nov 2024 23:48:00 UTC on a fiber-optic cable deployed along the sandy beach at Sizihwan, Kaohsiung, Taiwan. The cable, with a total length of 1 km, includes approximately 300 m buried in an 80 cm deep trench within the beach to enhance coupling with the surrounding sediments. The cable layout forms a rectangular geometry along the shoreline. The detailed description and key finding from this dataset can be found in the paper entitled "Tide‑modulated ocean‑to‑Earth energy conversion quantified with coastal fiber sensing" by Ko et al.
