| Research Abstract |
We investigated material transport from the East China Sea to the Japan Sea based on field observation, and spatial and temporal variation in sea surface current field using satellite altimetry data. It was found that interannual variation in material transport from the East China Sea to the Japan Sea was quite large, and the variability was caused by the change of current field in the East China and Yellow Seas. We revealed characteristics of sea surface current variation in the East China and Japan Seas using satellite altimetry data. Moreover, we developed a tidal assimilation model in order to improve the accuracy of the altimetry data in the East China and Yellow Seas.
