Outline of Final Research Achievements

Elucidating tidal mixing in the Indonesian Archipelago, which strongly controls global climate change, is essential for improving the accuracy of global climate change projections, but previous microstructure observations have been much limited.
In this study, the world's first large-scale turbulence observation using the VMP-X (Vertical Microstructure Profiler eXpendable) was conducted in this area. The results showed that strong turbulent hotspots exist locally due to the breaking of internal tidal waves over marine ridges and seamounts in narrow straits. Furthermore in these narrow straits, not only vertical mixing due to the breaking of internal tidal waves but also horizontal mixing enhanced by sub-mesoscale topographic eddies were found to play important roles, causing significant water mass transformation within a very short distance.

Academic Significance and Societal Importance of the Research Achievements

本研究は、気候モデルのアキレス腱となっているインドネシア多島海の潮汐混合に関わる不確定性を解消する画期的な研究である。理論により予測された「乱流ホットスポット」において乱流データを取得することで、同海域での潮汐混合の定量化、さらに、同海域における水塊変質のメカニズムの解明に取り組んだ極めて意欲的な研究である。これらの成果は、今後、海洋大循環モデルの高精度化、ひいては長期気候変動予測の高精度化に貢献するものと期待することができる。
