Research Abstract

In this sutdy, we focused on the processes of material transportation from coastal region to offshore region through surface layr. We selected Tokyo, Ise, and Osaka Bays as typical coastal regions which are connected to the Kuroshio water and are also facing to industrial area and high density of population region considered as most eutrophicated coastal zone. Material transportation from these bays to offshore through surface layr might be responded to variation of main Kuroshio Path as oceanic forcing from offshore to coast. The objective of this study is to clarify an mechanisms on material transportation and to estimate quantitatively the volume of material transportation. We attempted interdisciplinary approach using combination satellite remote sensing, numerical modeling, and in-situ synoptic observation. This approach with comparison of three bays should be defined as an comparative coastal oceanography. Summary of our results is as follows : (1) There is a difference outflow process of suspended matter between Ise Bay and other Bays in winter. (2) Outflow patterns of suspended matter from Tokyo Bay is defined two patterns by using high resolution satellite remote sensing. (3) We examined a ratio of outflow of suspended matter from surface layr and bottom layr. (4) We developed coastal diagnostic numerical model for each bays. (5) The characteristics of the variation in the Kuroshio path south of Japan is studied by use of the observational distance of the main Kuroshio path from Japanese Coast over period of 1995-1994. (6) Budgets of fresh water, salt, DIP and DIN in Tokyo, Ise, Osaka Bays are studied and we understand the characteristics of material cycling of each bay.
