Advances in ocean-bottom seismic observations with seismometers, hydrophones, and pressure gauges have provided us with the opportunity to study seismicity, subsurface structures, and wave phenomena in offshore areas. Permanent (cabled) observatories have enabled long-term monitoring for these targets, and deployments of dense temporary arrays or fiber optic technologies have opened up the possibility of a high-resolution research. Also, such growths of ocean seismology have compelled the community to create/modify data processing techniques. The purpose of this session is to share recent advances in seismology from data obtained in the oceans, including new seismicity and seismic velocity, progress in instrumentation, data processing on active and passive seismic approaches, and characterization of ambient noise. We also welcome presentations by early-career researchers or students who have little experience in international conferences.
