Abstract

Distributed acoustic sensing (DAS) technology holds considerable potential for marine geophysical surveys by transforming standard optic cable into dense arrays of seismo-acoustic sensors and gathering seismic data of shallow stratigraphic profiles. Here, a field trial with an abyss-class DAS system was carried out at 1423 meters depth in the South China Sea, and more than 600GB data was collected for 21 days. The vibration events of the marine integrated experimental base station were recorded, including entering, moving, landing and raising. The time and spectral domain characteristics were analyzed to reveal the station working statuses. The sea trial demonstrates the capability of the abyss-class DAS system for long-term seismic data acquisition in deep-sea environments.
