| Outline of Final Research Achievements |
We have proposed a next generation large-scale array experiment in the ocean called Pacific Array. Recent advances in ocean bottom broadband seismometry, together with advances in the seismic analysis methodology, have enabled us to resolve the regional 1-D structure of the entire lithosphere/asthenosphere system, including seismic anisotropy, with deployments of ~15 broadband ocean bottom seismometers. Having ~15 BBOBSs as an array unit for a ~1-year deployment, and repeating such deployments in a leap-frog way or concurrently (an array of arrays) for a decade or so would enable us to cover a large portion of the Pacific basin. With this JSPS support, we took a leadership to organize international collaborations; as a result, three array deployments are funded so far in various countries (US, Japan, and Korea).
