中文摘要：水东单点系泊海洋浮标站,设置在水东港附近,水深25m.利用波浪自记仪、ADCP流速剖面仪(座底)和CTD等,对水文(浪、流、潮、温、盐)和气象(海面风速和风向)进行综合观测,历时一年.其潮流特征为:表、中层流向出现最多的频率是:WSW.低频流出现频率最多的方向和潮流基本一致.10月～第二年4月的这7个月中,WSW出现率最高:表层平均出现频率52.1%,中层平均出现频率52.6%;而5～9月这5个月中,表层平均出现频率25.5%,中层平均出现频率21.3%.

外文摘要：Oceanographic Buoy Shuidong-1 was located near Shuidong Habour, where the water depth is about 25m, equipped with a wavemeter. ADCP. CTD and an anemometer. The waves, currents in different layers, tide, temperature and winds were measured from November 2000 to October 2001. The characteristics of the tidal currents are as follows： The tidal current direction with the maximum frequency in the surface and middle layers was WSW. The direction of the low frequency current with maximum frequency was also WSW. The surface mean frequency of low frequency WSW current from October to the next April was 52.1%; The mean frequency of the low frequency WSW current in the middle layer from October to next April was 52.6%. The surface mean frequency of the low frequency WSW current from May to September was 25.5%; The mean frequency of the low frequency WSW current in the middle layer from May to September was 21.3%.
