Seasonal Variation of Oceanic Conditions in Suyoung Bay

In order to study the seasonal variation in the physical properites in Suyoung Bay, we investigated the distributions of temperature, salinity, transparency and water color from May 1989 to April 1990. We also observed the tidal currents from February 27 to March 6 1990. There are conspicuous seasonal variation in water temperature and salinity. Water masses are characterized by two water types, i.e., one is influenced principally by river runoff and the other by the Tsushima Current. Transparency and water color increased gradually from the head of the bay to the mouth of the bay in all seasons. In winter, the transparency of water becomes minimum due to the enhanced vertical mixing.
