Fuji, Yamanashi Prefecture, Japan Time: January 21-27, 2001 _/_/_/_/_/_/_/_/_/_/_/_/ _/_/_/_/_/_/_/_/_/_/_/_/ _/_/_/_/_/_/_/_/_/_/_/_/ Many different disciplines require long term observations in the oceans in order to make significant progress in the understanding of various global scale processes. Thus, an opportunity exists for the development of interdisciplinary research and common infrastructure involving solid earth geophysics and geology, on the one hand, and physical as well as biological and chemical oceanography on the other. In the past few years, several initiatives have been started to establish ocean floor geophysical observatories towards improving our understanding of solid earth dynamics. The Japanese Ocean Hemisphere network Project (OHP), which aims to cover the East Asia-West Pacific area by a permanent geophysical network consisting of seismological, geomagnetic, and geodetic sensors, is one leading example. A first international symposium on "New Images of the Earth's interior through long term ocean-floor observations" was organized by OHP in November 1997. On the other hand, the International Ocean Network (ION), which aims to coordinate ocean floor observatory initiatives on the international scale, organized its first international Symposium in Marseilles in January 1995, bringing together scientists interested in global observatories and in the more regional monitoring of active geological processes. The first half of this joint OHP/ION Symposium will be mainly devoted to summarizing the results of the OHP and similar ION related programs: i.e. mantle dynamics (emphasis on western Pacific), coupling of the atmosphere and ocean with the solid Earth, observations that can improve our understanding of these phenomena, and data archive and distribution. The last two days will be devoted to more general issues regarding ocean observatories, including scientific potential and technical needs for joint geophysical/oceanographic seafloor/ocean observatories. ------------------------------------ ------------------------------------ International Steering Committee: Hitoshi Kawakatsu (Co-Chair), K.
