To promote discussion on mutual interaction between Continental and Oceanic zone, we have organized series of scientific session entitled as"Continental-Oceanic Mutual Interaction: Global-scale Material Circulation through River Runoff"since 2009 at Japan Geoscience Union (JpGU) annual meeting. Discharge from Continental-scale river basin is influenced by the fluctuation of SST from surrounding ocean. For river basin in South-American continent, it is well known that there are correlations between Discharge in Amazon River Basin and ENSO, together with Northern/Southern Tropical Atlantic Cold. From 2022 we also addresses the concept of "Core Biome Complex" as essential components of continental-oceanic terrestrial ecosystem aiming for migrating into different planetary environment. We aim to evaluate (1) importance of river-ocean system in global-scale heat&material circulation and (2) possibility and its scale in creating "artificial ocean" into different planetary environment.
