The observations of hourly change of salinity and temperature were made in the Korea Strait from August 1968 to July 1969. The largest hourly change of salinity and temperature was shown in August and the smallest in April. The range of hourly change of temperature (5.67-15.75$^{\circ}C$ on the depth of 125m) and salinity (32.1-34.3 on 20m layer) were significantly wide in August. These changes are correlated with the movement of water masses vertically and horizontally caused by changing direction and force of the current.

하계 대한해협 서수도에는 연직적으로 특성이 서로 다른 세 개의 수괴가 존재한다. 그 중 표층수에 대하여 인접 해역의 해수 특성과 상호 비교함으로써 그 기원과 유로를 추정하였다. 그 결과, 표층수는 동지나해의 대륙붕 상에서 형성된 Kuroshio수와 중국대륙연안수의 혼합수로써, 중국대륙연안수의 영향을 더 많이 받는 것으로 나타났다. 대부분의 표층수는 Kyushu Island의 서쪽 해역, 경도 126$^{\circ}$E와 127$^{\circ}$E 사이 해역과 제주도 동쪽 해역을 거쳐 유입되고, 한국 연안 부근에 있는 일부 표층수는 제주도 서쪽해협을 거쳐 유입된 것으로 나타났다.

It was found that three different water masses were vertically situated in the western channel of the Korea Strait in summer. Of these water masses , the origin and inflow path of the middle water were discussed and estimated by comparing with water characteristics of neighbouring sea. As a result, (1) the middle water is formed on the continental shelf in the East China Sea by the mixing of the Kuroshio Water and Chinese Continental Coastal Water, (2) the middle water seems intruded through the sea around 127 E west off Kyushu Island and east off Cheju the Island.

The relative geostrophic velocity is estimated by using the MCSST(Multi-Channel Sea Surface Temperature) from a NOAA/AVHRR image and applied to the Korea Strait. Remote sensing technique can play a useful role to research for oceanic phenomena because of its synoptic, simultaneous and repetitive viewing. The high resolution data of AVHRR can determine the geostrophic flow more precisely than the hydrographic data on shipboard. As a result of research, the relative geostrophic velocity in the weatern channel of the Korea Strait is the strongest in the trough area and its maximum speed is about 23.8cm/sec in April, 1992. But this results include the error due to neglecting the effect of salinity in estimation the geopotential anomaly. The geostrophic volume transport through the western channel of the Korea Strait is the largest between trough area and the Tsushima Island.

A picophytoplankton has been isolated from the western channel of the Korea Strait. The cell was isolated by dilution method. It is about 2 ${\mu}m$ in diameter and has smooth surface. Organelles of nucleus, chloroplasts, mitochondrion, Golgi body, pyrenoids, vacuoles and lipid bodies are identified. Pigments are composed of chlorophyll a and chlorophyll b, ${\beta}$-carotene and other xanthophylls. Based on the ultrastructural features and pigment composition, it may belong to chlorococcalean picoplankton.

Vertical distribution of tidal currents in the Korea Strait is computed by a tree-dimensional tidal model. The results are presented in the from of tidal charts (coamplitude and cophase chart) and (tidal ellipses charts for eight tidal constituents (M$_2$, S$_2$, $N_2$, $K_2$, $K_1$, $O_1$, P$_1$, Q$_1$) and of harmonic constants for predictions of tides and tidal currents during specified duration in the region. The computed tides were in general agreement with coastal observations and observation-based tidal charts of Odamaki (1989). Comparison between model computation and current observation by RIAM were also presented.

To investigate a short-term (from 2 hours to 24 hours) variability of a mixed layer, oceanographical data (water temperature, salinity, current) and meteorological data (wind, air temperature, solar radiation) were collected at a site in the Korea Strait at the interval of one hour for 48 hours from October 12 to 14, 1993. The average rates of temporal variations of the mixed layer depth (MLD) and temperature of the mixed layer (MLT), which are very weakly correlated with the wind stress and buoyancy flux at the sea surface, are about 5.2 m/hour and 0.2$^{\circ}C$/hour, respectively. The mixed layer is relatively shallow when both MLT and MLS (salinity of the mixed layer) are low, while MLD is relatively deep when they are high. MLT shows a sudden decrease or increase. Analysis of satellite infrared images and XBT data shows that sudden increase of MLT is caused by advection of warm water. These results suggest that the short-term variation of the mixed layer in the Korea Strait in autumn, in which surface current is relatively strong and different water masses exist, is mainly determined by advection rather than air0sea interaction such as wind stress or buoyancy flux.
