麗水沿岸 定置網 漁場의 周邊 海域을 中心으로 1989년 1월부터 1990년 12월까지 每月 調査한 水溫ㆍ鹽分 資料를 利用하여 漁場 周邊 海域의 海況特性을 分析 整理한 結果를 要約하면 다음과 같다. 1) 漁場 周邊 海域의 水溫과 鹽分 變化는 季節에 따라 각기 다르게 나타나 冬季는 表ㆍ底層水가 거의 均質 狀態로 水溫 7.0~13.5℃, 鹽分 31.40~33.40‰의 範圍이고, 灣內쪽에 低溫ㆍ低鹽分, 外海쪽에 高溫ㆍ高鹽分水가 分布하고 있다. 春季는 13.5~20.0℃, 30.40~32.60‰의 水溫.鹽分의 範圍로 水溫은 上昇하고 鹽分은 下降하여 全 海域의 水溫ㆍ鹽分의 水平傾度가 冬ㆍ夏季에 비하여 작다. 夏季는 16.0~27.0℃, 27.60~33.20‰의 水溫ㆍ鹽分의 範圍로 年中 最高水溫과 最低鹽分이 出現한다. 또한 內灣水와 外海水의 相接으로 水溫ㆍ鹽分前線을 形成한다. 秋季에는 表ㆍ底層 9.5~21.0℃, 31.40~33.20‰의 水溫ㆍ鹽分의 範圍로 春季보다는 高水溫ㆍ低鹽分이나 10월 이후부터는 水溫과 鹽分의 垂直ㆍ水平傾度가 크게 減少하여 全 海域이 春季와 같이 거의 均質水가 된다. 2) 冬, 春, 秋季는 鉛直混合이 비교적 잘 이루어져 表ㆍ低層間의 水溫ㆍ鹽分差가 크지 않지만 夏季에는 內灣水가 10m 미만의 表層을 따라 外海쪽으로 넓게 擴張하므로 表ㆍ低 層間의 鉛直混合이 잘 이루어지지 않아 表層에서 10m사이에는 鉛直傾度 2.0℃/10m, 4.0‰/10m 정도의 심한 水溫ㆍ鹽分躍層이 形成된다.

In order to investigate the oceanographic conditions of set net ground in the coastal waters of Yeosu, oceanographic observations on the sea area were carried out from Jan.1989 to Dec.1990. In winter, the distribution of water temperature and salinity, in the sea area not only at the surface but also at the bottom, was nearly homogenous, ranging from 7.0℃ to 13.5℃ and from 31.4‰ to 33.4‰ respectively. In the inner bay showed low temperature and high salinity, but the reverse took place off shore of the sea area. In spring, the water temperature increased ranging from 13.5℃ to 20.0℃, but the salinity decreased to the range of 30.4‰ to 32.6‰. The horizontal gradients of these temperature and salinity in spring were lower than those in summer and winter. In summer, water temperature and salinity was from 16.0℃ to 27.0℃ and from 27.6‰ to 33.2‰ showing highest temperature and the lowest with salinity in a year. Inner water and offshore water was made the thermalfronts and halofronts prevailed in the vicinity of Sori-do and Sejon-do. In autumn, the temperature and salinity varied from 9.5℃ to 21.0℃ and from 31.4‰ to 33.2‰ respectively. These values were high in the temperature and low in salinity in comparison with these in spring. From octover, vertical gradients of temperature and salinity became small and the sea area was occupied by almost homogeneous water. As the vertical mixing was made frequently in spring, autumn and winter, the differences of temperature and salinity between surface and bottom was respectively small. In summer, however, the mixing was not made because of the inner water expended offshore through the space between surface and 10m layer and so a thermocline of 2.0℃/10m and helocline of 4.0‰/10m respectively in vertical gradient was formed.
