우리나라 연근해에서 일시에 대량으로 어획되는 정어리 (Sardinops melanostictus)는 현재 주로 액젓의 원료로 쓰이고 있는 멸치와 같이 청어목, 청어과에 속하며, 동해 남부해역에서 월동을 하고 봄이 되면 북상하는 계절 회유성 어종이다. 정어리는 대표적인 등 푸른 생선으로 양질의 아미노산 및 핵산관련물질과 같은 맛 성분의 함량이 높지만, 어체가 작고 잔뼈가 많아서 가공을 위해 기계적으로 처리하기에는 부적합한 결점을 지니고 있다. (중략)

참조기(Pseudosciaena polyactis Bleeker)는 농어목 민어과에 속하는 어류로 한국을 비롯하여 중국, 대만, 일본 등지에 분포하며, 연간 총 어획량은 약 279,100톤으로 중국 262,800톤(94％), 한국 15,300톤(5.5％), 대 만 1,000톤(0.4％)을 어획하고 있다(FAO, 2000). 한국에서의 참조기는 황해 및 동중국해 해역에서 주로 근해안강망, 기선저인망, 유자망어업에 의하여 주로 어획되고 있다. (중략)

It is statistically analyzed the underwater ambient noise measured at 13 sites less than 200 m deep in the shallow water surrounding the Korean Peninsula for 9 yews from 1990 to 1998 in various environmental conditions. Frequency spectra were obtained with the 1/3-octave band center frequencies from 25㎐ to 20 ㎑. The analyzed shallow water noise spectra were some different from the deep water blown as the Wenz spectra. We could know that the ambient noise level shows higher than it in same condition by effect of various ship activity and the coastal noise, surface waves, and so on. As a result, we produced the coastal ambient noise spectra curve based on these results in shore of the Korea Peninsula.

Red tide(harmful algae) in the Korean Coastal Waters has a given a great damage to the fishery every year. However, the aim of our study understands the influence of meteorological factors (air and water tempaerature, precipitation, sunshine, solar radiation, winds) relating to the mechanism of red tide occurrence and monitors red tide by satellite remote sensing, and analyzes the potential area for red tide occurrence by GIS. The meteorological factors have directly influenced on red tide formation. Thus, We want to predict and apply to red tide formation from statistical analyses on the relationships between red tide formation and meteorological factors. In future, it should be realized the near real time monitoring for red tide by the development of remote sensing technique and the construction of integrated model by the red tide information management system (the data base of red tide - meteorological informations).

As satellite altimetry is being progressed to apply with higher precision to maginal seas. it is necessary to improve correction procedures for tidal signals in altimetry with more accurate tidal model than the well-known model of Schwiderski for studying marginal sea dynamics. As a first step, tidal regime of semidiurnal tides (M$_2$, S$_2$, $N_2$, $K_2$) and diurnal tides (K$_1$, $O_1$, P$_1$, Q$_1$) were computed with finer details of formulation of tidal model over the East Asian Marginal Seas covering the Okhotsk Sea and South China Sea and part of Northwest Pacific Ocean with mesh resolutions of 1/6$^{\circ}$. Computed results were discussed with observations, previous tidal charts and Schwiderski's tidal map of the region.

The sharks identified in the coastal waters of Korea are known to date to 9 Orders, 21 Families, 32 Genera and 47 Species. Therefore, recent studies and records of shark appearance in Korean waters were reviewed and organized. As a result, Halaelurus buergeri was separated from the Family Scyliorhinidae into the Family Pentanchidae based on the supraorbital crest absent on cranium above eyes. Accordingly, compared to the previous study, Family Pentanchidae, Genus Hexanchus, and 2 Species Hexanchus griseus and the Alopias superciliosus were added, resulting in a total of 49 species of sharks in 9 Orders, 22 Families, and 33 Genera in coastal waters of Korea. A list of these species, a search table, and the history of scientific name changes are provided, and proposed a new Korean name of 'Bul-beom-sang-eo-gwa' of the Family Pentanchidae.

The radio field environment is very different according to frequency band, therefore communication condition is equation that VHF is passed by direct radiation and HF is via reflect radiation in ionosphere. Load a ship according to the enforcement regulations of the ships safety act have specificated the radio equipment that should be operating. This paper have analysed by the simulation program about radio field environment for research the communications condition, which is VHF & HF band in domestic coastal. We have Predicted to radio field environment and communications condition using the data of analysis and domestic radio regulation regard to coast navigational ship. Therefore have proposed the necessity for rationally plan on improvement the radio regulation and network cooperation of VHF radio station.

We studied the characteristics of catch fluctuation and distribution of yellow tail resources in Korean Waters from 1991 to 2000. The obtained results are summarized as follow, The distribution of yellow tail resources in Korean Waters was showed by mooving north-ward groups from Spring to Autumn and south-ward groups from Autumn to Winter with they passed Winter and spawned from the south of Jeju Island and Tsushima current. Therefore, the fishing ground of yellow tail by handline fishing around Marado targets a school of yellow tails which migrate south-ward so as to winter and spawn.

There was a close relationship between spatio-temporal distribution of Cochlodinium polykrikoides red tide and meso-scale variation of oceanographic environment around the Korean waters. Oceanographic conditions of Narodo island, where red tide usually first occurred during summer seasons were formation of the thermohaline frontal zone from 1995 to 2001. Huge C. polykrikoides red tides were observed in every uneven year during the past 7 years (1995~2001) and quasi-biennial oscillation also occurred in the oceanographic variations of sea surface temperature and salinity in the northern part of the East China Sea during the same years. The distribution area and moving pattern of C. polykrikoides red tides were definitely depended on the temporal and spatial variation of upwelling cold water originated form the southeastern coast of the Korean peninsula in summer season.
