[M-IS19] Integrated Analysis of Geoscience Observations from the Floor to Surface of the Ocean

Fri. Jun 4, 2021 5:15 PM - 6:30 PM Ch.21

convener:Keisuke Ariyoshi(Japan Agency for Marine-Earth Science and Technology), Narumi Takahashi(National Research Institute for Earth Science and Disaster Resilience), Motoyuki Kido(International Research Institute for Disaster Science, Tohoku University), Daisuke Inazu(Tokyo University of Marine Science and Technology)

Sea bottom pressure data contains various components such as crustal deformation, oce
an oscillation, tidal variability, atmospheric change, and instrumental drift. So far, seismo
logists have treated the ocean oscillation as noise, and ocean physicists have done vice v
ersa (considering crustal deformation as noise). Such problems apply to ongoing underse
a acoustic distance measuring and other types of ocean observations. In this session, we
welcome contribution on various topics focusing on the complementary relationship betw
een seismology, ocean physics, meteorology, tsunami technology, and other related field
s.
