Exchange processes between shelf and basin, Interaction between coastal circulations and western boundary current 陸棚−海盆間の海水交換、沿岸循環と西岸境界流の相互作用

Research Interests / 研究内容

We are investigating interaction between coastal and open-ocean regions: Descent and/or upwelling of seawater along the continental slope, interaction between coastal currents and western boundary currents, and so on.

沿岸と外洋域の間で生じる海水交換過程や力学相互作用を調べています。陸棚斜面に沿っての海水の沈降や湧昇、沿岸循環と西岸境界流の相互作用などがあります。
