项目摘要

Tidal currents survey by 1200KHz ADCP was carried out twice (each 3 days in September, 1994 and in June, 1995) to investigate flow patterns and observation of sea water (temperature and salinity) was done every month from April 1994 to May 1995 to study seasonal changes and characteristics at Hamato bay in the Yuge Island.Results of these survey and observation were summerized as follows ;1)The tidal currents were roughly found to be barotropic at the surveying lines.2)The geographic eddies were generated around the point B of the AB surveying line owing to the headland effect.3)At the time of the ebb, the counter currents were turned clockwise at the inside of the bay, and the off-shore currents were roughly found to be formed at the middle part of the bay.4)In the flood, the counter current were found to flow anti-clockwise along the coast line of the bay.5)The salinity of the water was on the increase in winter and its peak value was over 34 psu in February, and this value was very high in the Sea of Hiuch.

利用1200 KHz ADCP进行了两次潮流测量（1994年9月及6月各3天，1995年），以调查流动模式和观察海水（温度和盐度）从1994年4月至1995年5月，每月对渔歌岛滨海湾进行一次调查，研究其季节变化和特征结果表明：（1）测线上的潮流大致为正压潮流;（2）由于岬头效应，AB测线上B点附近产生了地理涡旋;（3）落潮时，湾内的逆流呈顺时针方向旋转，近岸流大致形成于湾内中部;（4）涨潮时，5）冬季海水盐度呈上升趋势，2月份最高达34 psu以上，尤以休奇海为最高。
