가막만 남쪽 화태도 주변의 해황 특성

The change of temperature, salinity, density, transparency, tide and tidal currents around Hwatae island in the south of Kamak bay, southern coast of Korea

Temperature, salinity, transparency, tide and tidal currents observations were carried out around Hwatae Is. in the south of Kamak Bay, southern coast of Korea in Februay, April, July and October 1994. Temperature showes its minimum value of 6~9℃ in February and maximum value of 18~23℃ in July. A weak stratification was formed in July, but the water in the study area was homogeneous in February. There are two differnt water mass around Hwatae Is.. One located at the southeast in the study area has the characteristic of oceanic water, the other at the northwest has that of the water of Kamak bay. Salinity was its lowest 32.5‰ in October, its highest 34.0‰ in April. Tidal form number estimated from the rate of the amplitude for diurnal tide to semi-diurnal tide is 0.23, then the semi-diurnal tide is dominant around Hwatae Is.. Semi-diurnal components of tidal currents flow WNW in flood tide, ESE in neap tide.
