Seismological advances in the ocean (S-SS06) in JpGU-AGU joint meeting (May, 2026)

[HyeJeong Kim]

Dear all,

We want to bring your attention to submitting an abstract to our session ⚓Seismological advances in the ocean (S-SS06) in the 2026 Joint JpGU-AGU meeting to be held from May 24 to 29!

We are hoping to gather everyone working on marine seismic observations, using various types of observatories and approaches!

Invited speakers: 
Kodai Sagae (GSJ, JP) on machine learning with N-net and S-net
William Wilcock (Univ. of Washington, U.S.A.) on long-term observation in  Cascadia and an introduction to the COSZO project
Yojiro Yamamoto (JAMSTEC, JP) on seismic tomography and submarine volcanoes
Chu-Fang Yang (Géoazur, FR) on oceanography applications with submarine cables


Deadline: 17 Feb (Tue) 17:00 JST (9:00 CET)

Submission link: https://www.jpgu.org/meeting_e2026/submission.php

See you in Chiba, Japan!

Sincerely,
Tatsuya Kubota, HyeJeong Kim, Helen A Janiszewski, Ayumu Mizutani, Takashi Tonegawa

=============
Session Scope:
Advances in seismic observations in the oceans with seismometers, hydrophones, and pressure gauges have provided opportunities to study seismicity, subsurface structures, earthquake and tsunami generation, and wave phenomena offshore. Permanent (cabled) observatories, and deployments of local- to regional-scale temporary arrays or fiber optic technologies promote analyses over unprecedented temporal and spatial scales, and are continuously expanding coverage in the oceans. Such developments in ocean seismology have also encouraged the community to create novel data processing and analysis techniques. The purpose of this session is to share recent advances in marine seismology, such as seismicity, seismic velocity structure from active and passive approaches, progress in developing new instruments and techniques for offshore seismic datasets, interactions between the solid earth and oceans, and new regional/global-scale experiments. We look forward to contributions from, but not limited to, the localization of submarine earthquakes and volcanoes and their relevant tsunamis, observation of the seafloor strong motion, characterization of ambient noise and interpretation of its sources, and propagation processes of various waves in the atmosphere, ocean, and solid Earth recorded by ocean instruments. This session welcomes offshore observations or analyses related to recent major earthquakes offshore, e.g., the Noto, Hyuga-nada in Japan, the Hualien in Taiwan, the Offshore Cape Mendocino in California, the Sand Point in Alaska, and the Kamchatka Peninsula. We recommend presentations by early-career researchers and students who would like to try presenting in an international session.
