  • In the southern sea of Korea and the areas of Tsushima warm currents the relationship between the distributions of eggs and larvae of anchovy (Engraulis japonica) and oceanic conditions was examined on July and August 1997, The south Korean coastal waters, the water temperature of below $20\~23^{\circ}$ and the salinity of above 33.0 (PSU), the mixed waters between the south Korean coastal waters and the Tsushima warm currents, $21\~25^{\circ}$ and $32.0\~32.5$ and the Tsushima warm currents, above $26^{\circ}$ and below 31.5 were distributed at the surface layer. The Tsushima warm currents were distributed at the northeast of Jeju Is. and off the southern sea of Korea. As an appearance of warm streamer, the mixed waters were intruded into the coastal areas of Komun Is.$\~$Sori Is. and Sori Is.$\~$Yokji Is.. Approximate paths of surface water by the drift card experiments were similar with the intrusions of the warm water identified from the water temperature and salinity distributions. The distributions of chlorophyll concentration were consistent with the distributions of water temperature and salinity, Anchovy eggs and larvae were mostly distributed at Komun Is., Yokji Is, and the southwest of Koie Is. where chlorophyll concentrations were high and cyclonic circulations by the warm water intrusions (warm streamers) were formed.

  • The distribution of anchovy eggs and larvae was studied using the ichthyoplankton samples and oceanographic data collected in the western and southern waters of Korea over the period of April through June in 1981 and 1982. Three water masses, the Tsushima Warm Current, the South Korean Coatal Water and the Yellow Sea Bottom Cold Water, are found to exert extensive influences of the distribution of anchovy eggs and larvae. The Tsushima Warm Current contacts with the South Korean Coastal Water to produce a coastal front between Cheju Island and Tsushima Island in the southern waters of Korea. Off the west coast of Korea, a coastal front is also formed running parallel with the western coast-line of Korea in the area between the Yellow Sea Bottom Cold Water and the extended part of the South Korean Coastal Water. In the southern waters of Korea anchovy eggs were found chiefly in the coastal waters inside the front, and larvae appeared to both sides on the front. The distribution of anchovy eggs and larvae off the west coast of Korea, however, was limited largely to the coastal waters of more than $12^{\circ}C$ in temperature. In the southern waters of Korea prelarvae appeared in the coastal area, and postlarvae in the offshore area. While in the western waters of Korea prelarvae were found in the southern part of the waters, and postlarvae in the northern part. Anchovy eggs and larvae were distributed in the considerably limited area of the coastal waters off the south coast of Korea in 1981 when the temperature gradient of the coastal front was sharper than in 1982.

  • 살조개, Protothaca jedoensis는 백합과에 속하며 우리나라의 남·서해 연안과 일본, 중 연안의 조간대에서 수심 20m까지 분포 서식하는 패류로, 바지락과 혼생하나 일반적으로 바지락보다는 깊은 곳에 서식하는 것으로 알려져 있다. 살조개는 남해 서부연안에서 식용으로도 기호도가 높은 유용 수산자원 품종이나, 이들 살조개에 대한 연구보고는 거의 없는 실정이다. (중략)

  • 우리나라 동해는 남해나 서해와는 달리 수심이 깊고 해안선이 단조로우며 급경사를 이루는 곳이 많은 지형적 특징을 가지고 있으며, 연안역은 생산성이 높은 해역으로 수 많은 해양생물이 산란, 생육 및 섭식의 장소로 이용하고 있어 어장으로서 가치가 매우 높은 곳이다. 특히 동해 중부연안은 동한난류와 북한한류의 영향을 동시에 받는 해역으로서 한ㆍ난류성 어류 및 표 저층성 어류 등 다양한 어종이 서식하고 있는 곳으로 알려져 있다. (중략)

  • 통영연안VTS 관제구역은 남해 주요 항만으로 가기 위한 중요 길목으로서 일평균 700 척의 선박이 이용하고 있다. 최근 3년간 통계 자료에 따르면, 관할 해역 전체 해양사고 중 내항 어선과 관련된 사고가 약 70 퍼센트를 차지하고 있다. 최근 해상교통환경이 복잡해짐에 따라 비관제대상인 내항 어선의 민원이 증가하고 있으며, 안전관리를 위한 대책 마련의 목소리가 높아지고 있다. 이에 제도적, 기술적 개선 방안을 중심으로 해상교통안전 증진 방안을 살펴보았다.
