We establish the equations of finite element approximation for three-dimensional ocean current and calculate the Kuroshio current in the eastern sea area off Taiwan Province. The interpolation error of finite element approximation is given as Eq.(3.14).

Abstract:
The theory of barotropic, shallow-sea ocean currents and storm surges considered from the viewpoint of air-sea interaction is presented. A 4-layer quasi-balanced dynamical model for a simulation of the structures of both the atmospheric and the marine planetary boundary layers is obtained by an analytical approach. A simplified scheme governing the storm surges induced by a slowly travelling circular atmospheric vortex is deduced.

Abstract:
The effects of boundary reflection loss, scattering loss caused by the rough surface and the radiative directivity of the surface sources (parameter m) on the ambient noise field in shallow-water homogeneous layer have been discussed theoretically. It has been found that the parameter m has the stronger controlling role on the behavior of the ambient noise field than others.

Abstract:
Based on the principle of laminar flow-constant potential-chronocoulometry, this article presents a new method of determining the dissolved oxygen in seawater with considerable success. A new model of electrochemical sensor has been designed for this purpose.
The sensor has the advantage of overcoming hysteresis and "outskirts effect", thus increasing its stability and prolonging its use to 1-2 years.
In connection with this new method a new model SY-1 integrating microcoulorneter with digital display is designed.
It is a fast (a sample/2 min) and accurate (±1-1.5%) method, suitable for use in the laboratory on board a ship.

Abstract:
Maximum vertical distribution of dissolved oxygen in the Huanghai Sea (Yellow Sea) and its mechanism are studied. The oxygen maximum in the summer thermocline is mainly conserved (derived) from winter.

Abstract:
The Bobai Gulf and its coastal basin is an important oil and gas province of China that covers an area of 200,000 sq. km.
It is a polycylic superimposed basin. Its history of development can be subdivided into four stages:(i) Late Proterozoic parageosydine stage (Sinian); (ii) Early palaeozoic cratonic stage (Lower Cambrian-Middle Ordovician):(iii) Late palaeozoic intracratonic coal bearing sequences stage (Middle Carboniferous-Permian); (iv) Mesozoic and Cenozoic taphrogenic rifting and subsidence stages.
During the Paieogene rifting stage, three NNE trough systems and three nearly EW trough systems were initialed as the results of regional extensional stresses. Central rift valleys, low angle gravity faults and a series of asymmetrical half-grabens were developed surrounding the "Bohai Mantle Plume". The riftitip troughs were egtended ard widened gradually.

Abstract:
By using the concept of the joint probability distribution of independent stochastic variables, this paper gives an analysis of the maximum total wave forces on pile groups due to irregular wave action on the basis of Ref.[1].
Methods for calculating the maximum total wave forces on pile groups considering both the wave energy spectrum and the directional wave spectrum are also given in this paper. Special computer programs MAXTOTWAF-PGZ-1 and MAXTOTWAF-PGZ-2 are developed for the purpose of calculation.

Abstract:
Based on the perturbation method, a fourth order theory for nonlinear interactions among three dimensional gravity waves in water of any uniform depth is presented in this paper. Two cases are considered:(i) wave number vectors fixed, frequencies perturbed, and (ii) wave number vectors and frequencies both fixed. According to this solution, expressions of thesame order for progressive waves, short-crested waves and nonlinear interaction between wave and vertical wall are also derived.
