【摘要】 <正> 一.概要1979年6—7月,中国科学院南海海洋研究所“实验”号在南海北部进行了一次海洋科学考察,其中在台湾海峡南面117°30′—120°00′E、21°00′—23°00′N布设7个大面站和1个连续站（见图1）的观测。海水化学要素的调查项目包括盐度、溶解氧、PH、可溶性无机磷酸盐和活性硅酸盐等,并以现场采水测定。海水中盐度的测定采用HD₂型实验室盐度计; 海水中溶解氧（下称氧）的测定采用Winker碘量法;更多还原

【Abstract】 Based on the data of salinity, dissolved oxygen,PH, dissolvable inorganic phosphate and active silicate, obtained from 8 stations close to the south of the Taiwan Strait in the northern part of the South China Sea, during the period from June through July,1979,on board the R/V SHIYAN of the South China Sea Institute of Oceanology,Academia Sinica, the present paper describes their horizontal and vertical distributions and diurnal changes, separately and preliminary analyses of the ir distributions.更多还原
