[A-OS13] Continental Oceanic Mutual Interaction - Planetary Scale Material Circulationn
Tue. May 24, 2022 5:15 PM - 6:45 PM Exhibition Hall 8
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. In this survey we are focusing on relationship with ENSO and IOD based on the hypotheses found in Chan et al. (2008). By analyzing correlation between precipitation data and IOD mode in the region there are some evidences that indicate relationship. Based on that approach we made comparison with long-term observed discharge. It is found that discharge in Amazon basin are widely affected and influenced from those surrounding SST together with IOD in long distance. We also address importance of promoting Continental-Oceanic mutual monitoring focusing exclusively during extreme events. This year we also addresses the concept of "Core Biome Complex" as essential components of continental-oceanic terrestrial ecosystem aiming for migrating into different planetary environment.
