초록
여수해만 수온의 시공간적 변동특성을 장기 연속수온관측 자료를 이용하여 분석하였다. 수온은 1월 말 최저, 8월이 최고로, 하계 남에서 북으로 갈수록 높아지고 동계는 낮아지는 패턴을 나타낸다. 연중 평균수온은 POSCO 동쪽연안이 가장 낮고 하동연안 대도서쪽이 가장 높다. 7~8월 섬진강 하천수 유량이 큰 시기 섬진강하구~해역중부에 저수온이 출현한다. 수온변동은 기온보다 약 15일 정도 늦다. 조석에 따른 반일 이하의 수온변동은 하동연안과 대도주변에서 가장 크다. 비조석 수온성분에서 동계 북서풍시 수온하강, 하계 남풍계열시 수온상승 경향을 나타낸다. 수온의 탁월변동주기는 0.5, 1, 12, 15, 20, 24일로, 조류변화에 따른 15일 전후 주기에서 빈도가 가장 크다. Coherence 분석결과, 해역남쪽과 노량수로 주변의 수온변동위상이 타 해역보다 빠르다. 상호상관계수분석으로 여수해만은 외해수 영향수역, 내만 고유수역, 섬진강 하구수역, 온배수 주변수역, 대도 연안수역, 진주만 영향수역으로 분류되었다.
Abstract
Temporal and spatial fluctuations of surface water temperature in Yeosu Bay for the period from 2010 to 2011 were studied using the data from temperature monitoring buoys deployed at 32 stations in the south coast of Korea. Temperatures in the northern part of the bay are higher in summer and lower in winter than in the southern part of the bay. The lowest and highest temperature of the annual mean are found at the eastern coast of POSCO and at the west of Dae Island, respectively. Cold water masses appear at estuarine area when the discharge of Sumjin river is affluent. Amplitude of temperature fluctuation whose period is less than semi-diurnal is largest at Hadong coast and around Dae Island. Spectral analysis of surface water temperature shows a significant peak at a periodic fluctuation of 0.5 to 24 days and about 15-day period of predominant fluctuation is most frequent in Yeosu Bay. From the cross-correlation analysis of temperature fluctuations, Yeosu Bay can be classified into six areas; the south area affected by South Sea of Korea, the mixed area in the center of the bay, the estuarine area affected by river discharge at the north of the bay, the hot waste water area near Hadong coast, the area around Dae Island and the area near Noryang Channel affected by the water in Jinju Bay, respectively.
