| Zusammenfassung |
| The Kuroshio flows along the edges of the marginal East Asian seas such as
the South China Sea (SCS) and East China Sea (ECS). Exchanges of materials
and energy between the Kuroshio and the marginal seas partly control the
environments of the marginal seas. In particular, saline water from the
Kuroshio maintains certain salinity in the shelf water in the ECS. Nutrients
from the subsurface of the Kuroshio may influence primary production on the
shelf. We summarize how the Kuroshio comes into contact with the shelf water
or marginal seas, describing phenomena related to the exchange between the
Kuroshio and the ECS along with the SCS, using reports in the literature
along with original data. The Kuroshio tends to intrude into the SCS through
the Luzon Strait in various manners such as direct intrusion, associated
with eddies and as a loop current. The Kuroshio intrusion into the shelf
region of the ECS has distinct seasonal variation and the Taiwan Warm
Current plays a significant role in the determination of water properties in
the outer shelf associated with the Kuroshio intrusion. We then examine
physical processes related to the interaction between the Kuroshio and shelf
water. Interaction between the Kuroshio and the bottom topography is an
important process in the control of the exchange around the shelf break.
Vertical mixing and frontal eddies are also important factors that control
the water exchange and formation of water masses in the outer shelf. Wind
stress plays a significant role in the exchange with a rather event-like
manner. To determine the source of the water masses, chemical tracers could
be powerful tools and it is suggested that a significant part of the shelf
water consists of Kuroshio intermediate water. |
