Seasonal distributions of temperature and salinity in the eastern coastal area of Sinji island

For the study of basic oceanographic condition in the Eastern coastal area of Sinji Island, temperature and salinity were observered in February, April, July and October 1994. The results are as follows; Water temperature distributes 9.0~14.0℃ and high at the eastern part and low at the western part of the study area in winter. This shows that cold water masses are developed in the northwest of Sinji Island by means of the surface cooling in winter season. On the other hand, in summer, water temperature rises at the western part near Jangjic Channel and decrease at the southern part of the study area deserving the southern sea of Korea. Surface salinity is low near Jangjic Channel and the coast of Sinji Island under the influence of fresh water all the year round. But owing to the south sea of Korea, the southern and eastern part of the study area have comparatively high salinity. 10 meters and bottom salinities are nearly homogeneous in all areas, which is considered as the effect of strong tidal currents existing in the study area.
