An initial attempt to establish predictive system of sea surface current and trajectories of drifting bodies for seas adjacent to Korea is described. A predictive system for the Korea Strait area was first set up based on Data Tables for surface tidal currents, surface wind-driven currents and density-driven currents. Simulations thus performed were in general agreements with satellite tracking buoy observations available in this region.

The Singapore Strait is one of the world's busiest waterways used by international shipping Coupled with this, the Port of Singapore is the world's busiest port in terms of shipping and cargo tonnage and the second busiest container port. Navigational safety is Singapore's concern and we are convinced that the ECDIS is the key to further enhancing navigational safety in the Singapore Strait and the port waters of Singapore. We have initiated the production of Electronic Navigational Chart data and invested in infrastructural supporting facilities such as DGPS brodcast service for use with ECDIS as well as other maritime systems.

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.

Northeast Asia comprises many characteristic cultural areas including China, Mongolia, Korea and Japan. These areas have their own traditional food cultures, and Korea is known as the home of fermented foods in this region. The origin of Northeast Asian fermented foods, cereal alcoholic beverages, fermented vegetables(kimchi), fermented fish and fermented soybean products were investigated in relation to the primitive earthen vessels developed in this region. The geographical and environmental background of the appearance of primitive pottery culture in the Korea Strait region, and its influence on the development of fermentation technology in Northeast Asia were reviewed focusing on Korean dietary culture.

The Tartar Strait currents of different scales are analysed using results of observations and modeling. The paper focuses on tidal phenomena and general circulation features. It is shown that the areas of maximal tidal currents are located in the regions of stable boundary streams. The stability of the streams under different meteorological conditions and energy concentration in the small areas may be explained by non-linear effects of tide over rough bottom topography.

The stony corals known from Korean waters are 24 species , 15 genera, 7 families in 5 suborders, of which 7 species are newly recorded to the Korean scleractinian fauna ; Montipora trabeculata, Oulangia stokesiana miltoni, Goniocorella dumosa, Dendrophyllia arbuscula, D.boschmai cyathohelioides, D. micranthus, and Rhizopsammia minuta mutsuensis. They were collected from 35 localities of southern Korea from 1969 to 1986. For the geographical analysis, the coastal waters of Koarea are divided into four regions ; the Yellow Sea, the Korea Strait, the Cheju Island area and the East Sea (Sea of Japan) . These are based on the species diversity , the geographical distribution form, and the community coefficient, Korean scleractinians consists of 8 temperate zone forms(33.3%, Te) and 16 tropical forms(66.7%, Tr) . Concerning the distribution in each region, 3 spp. (2 Te, 1 Tr) occur in the Yellow Sea, 9 Spp. (5 Te, 4 Tr) in the Korea Strait, 16 spp.(4 Te, 12 Tr) in the Cheju Island area and 5 spp. (2 Te, 3 Tr) in the East Sea. The communicty coefficient between the Korea strait and the East Sea is the highest (0.596), and that between the Yellow Sea and the Cheju Island area is the lowest(0).

A phytoplankton study in the Korean waters has been commenced from 1964 as parts of the primary production studies in the Korean waters and the cruise for the cooperative studies of the Kuroshio from 1965 to 1968. Samples are taken by dipping 300-500 ml of sea water from the surface, and then fixed by adding neutralized formalin. The phytoplankton identification and cell counts are made on samples carefully after concentrated by decanting and centrifuging in the laboratory. This report deals with the surface phytoplankton obtained during the period of August 14-27, 1965 at twenty-three stations in the Korea Strait. Fifty nine species in seventeen genera of diatoms are detected from the samples collected at the stations. Among them seven species in five genera are considered to be purely neritic or cold water species and eight species in four genera are oceanic species of the Kuroshio. The highest phytoplankton standing crops are found in the sea area neighboring coastal waters of southern Korea, and the species distribution show anomalies in normally oceanic species being confined to neritic waters. There are distinct genera compositions of eastern, western and intermediate sea areas in the Kore Strait.

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.

Structure of thermocline, characteristics of stability and intensity of vertical transfer have been studied with hourly oceanographic data in each layers on Line 207 from 1968 to 1969. It is found that a typical thermocline is formed at depths of 10 to 50 meters in summer and early autumn and its core is located near depths of 25 meters. The maximum diffusion coefficient of vertical turbulent is found to be 140$\textrm{cm}^2$/sec at the surface layer(i.e., 0-10 meters), while the minimum is 5$\textrm{cm}^2$/sec at depths of 25 meters, consistent with characteristics of stability and structure of thermocline layers. Our computed diffusion coefficient and stability indicate that the mixing hardly takes place below depths of 80 meters during summer and early autumn, but for the rest of the season mixing could move up to the depth of 50 meters. It appears that the Western Channel of the Korea Strait consist of three different water masses during summer and autumn, and for the rest of the season, two kinds are present.

Sea ices at the Tatarskiy Straitin the East/Japan Sea appear from November to April. Cold and fresh water, melted from the sea ices, may contain nutrients which are indispensable to spring bloom of phytoplankton and may provide a preferable condition to the spring bloom through changes in vertical structure of water column and stratification. Relation between the spring bloom along the Primorye coast and sea ices in the Tatarskiy Strait were investigated using multi-satellite multi-sensor data; ten-year SeaWiFS chlorophyll-a concentration data and PAR data, sea surface temperatures from NOAA/AVHRR, sea ice concentration and near-surface wind speed data from DMSP/SSMI, near-surface wind vectors from QuikSCAT, and others. We provided evidences of southwestward flowing cold water masses from sea ice and its relation of chlorophyll-a concentration. This study showed that year-to-year variations of chlorophyll-a concentration in spring were positively correlated with those of sea ice concentrations at the Tatarskiy Strait.
