Abstract
The distributions of the temperature and salinity in Kamak bay which has two channels and three sea bottom topographic parts were studied by taking the detailed hydrographic data at the ebb and flood during four seasons from May, 1988 to Feb., 1989. The general pattern of the distributions of characteristics which the temperature and salinity has in Kamak bay is basically formed by the topography and sea water movement of the bay. The changes of these distributions by seasons mainly come from the heating and cooling of the sea surface and the increase of the run-off. The bay has three remarkable water masses and the their general characteristics are follows: the inner bay water has a stagnation character influenced by the inland and the concave of the sea bottom in the north west, Yosu harbor water has an estuary character of the low salinity caused by the run-off of Somjin river and Yon Tung brooklet in the north east, and the outer bay water has an out-sea character, as it is located near by the big mouth in the south of the bay. The distributions of those water masses at the ebb and flood show some different features due to the flow patterns, and the daily changes of oceanic conditions at the vicinity of Hangdae-ri are so big that it may influence the habitation and production of the living things in the bay.
내만역의 해양 구조를 규명하고 어장 관리를 위한 기초 자료를 얻기 위하여, 가막만에서 계절별로 1958년 5월부터 1989년 12월까지 밀물과 썰물때의 수온, 염분, 투명도 및 수색을 관측하였다. 그리고 이들의 분포와 수괴 특성을 검토한 결과 그 양상이 일반적으로 지형적 요인과 해수 유동 구조에 의해서 크게 좌우됨을 알았다. 연중 수온 분포값은 7.2(2월)
