신지도 동쪽 주변해역의 조위변동과 수온의 변화

Time changes of sea level and temperature in eastern coastal area of Sinji island

Sea level changes and sea surface and 5 meter temperatures were observed in the east (station S-1) and the north (station S-2) of Sinji Island during 25 hours from 4 February to 5 February 1994. Tides at two stations showed a feature of the mixed tide in which both semi-diurnal and diurnal tide were concurrently existed but the semi-diurnal tide was dominant. Amplitude of the tide at station S-1 was two times as high as that at station S-2. It suggests that the tide of the eastern part of Sinji island has the feature of the tide in South Sea of Korea and that of the northern part showes the feature of the tide in shallow waters. Sea level changes in the north of Sinji island were similar with those in Wando Harbour. Water temperatures at station S-1 were higher than at station S-2. Water temperatures rised and fell in accordance with the semi-diurnal tidal period dominant in the eastern and northern parts of Sinji island.
