[M-IS13] Integrated Analysis of Geoscience Observations from the Floor to Surface of the Ocean

convener:Keisuke Ariyoshi(Japan Agency for Marine-Earth Science and Technology), Joan S Gomberg(USGS Earthquake Science Center), Narumi Takahashi(National Research Institute for Earth Science and Disaster Resilience), Motoyuki Kido(International Research Institute for Disaster Science, Tohoku University)

Sea bottom pressure data contains various components such as crustal deformation, ocean oscillation, tidal variability, atmospheric change, and instrumental drift. So far, seismologists have treated the ocean oscillation as noise, and ocean physicists have done vice versa (considering crustal deformation as noise). Such problems apply to ongoing undersea acoustic distance measuring and other types of ocean observations. In this session, wewelcome contribution on various topics focusing on the complementary relationship between seismology, ocean physics, meteorology, tsunami technology, and other related fields.
