Research explores controlling seabed stiffness using seismic amplitude modulation.

DAS enables low-cost, high-resolution seafloor monitoring.

Applications include geophysics, oceanography, and seismic imaging.

The research, presented as a preprint on the ESS Open Archive, delves into the novel application of Distributed Acoustic Sensing (DAS) technology for controlling seabed stiffness through seismic amplitude modulation. DAS leverages existing subsea fiber-optic communication cables, transforming them into dense arrays of seismic sensors. This method offers a cost-effective and high-resolution approach to measuring acoustic signatures and seismic vibrations along the seafloor. By analyzing the backscattered light modulated by mechanical disturbances, DAS can detect a wide range of phenomena, from earthquakes and volcanic activity to marine life vocalizations. The scientific community is actively exploring DAS for various applications, including near-surface seismic imaging, underwater acoustic monitoring, and potentially for understanding and influencing seafloor properties. The ESS Open Archive serves as a crucial platform for disseminating such early-stage research, promoting open science and rapid communication within the Earth and space science fields. While this specific study is a preprint, it represents the cutting edge of research in leveraging telecommunication infrastructure for advanced geophysical and oceanographic monitoring, with broad global implications for scientific understanding and technological development.
