The study of the temporal and spatial characteristics of western boundary current East of Ruykyu submarne ridge and the transport of Kuroshio in East China Sea;

Numerical Analysis of Kuroshio Chaos;

Using semidifferential stripping technique combined with pre-equibrium complex-ometric titration, the apparent copper complexing capacity (AXuCC) of seawater and the conditional formation constant (Kc) of copper-natural organic ligand of 65 seawater samples collected in the Kuroshio area in the East China Sea "in 1989 were determined.

Diagnosis of the Kuroshio in the East China Sea along the PN-line with Geostrophic Empirical Mode Method;

Kuroshio in the East China Sea is studied as an important impact on the East China Sea circulation.

In this paper,a physical pattern of subcirculation system in the main part of the Kuroshio in the East China Sea is suggested by analyzing different survey data,and the subcirculation system is a double-loop circulation structure consisting of a relatively stable main stream of the Kuroshio,a frequently occu-ring right side countercurrent and a conditionally occurring outer shelf countercurrent.

Based on the hydrographic data of five cruises in the Kuroshio area of the southern East China Sea in spring from 1988 to 1996, the geographical distribution of vertical distribution types of temperature and salinity in the area are analyzed, and the causes of the reverse phenomenon of temperature and salinity in spring are discussed in detail.
