台湾海峡南部海水化学要素分布状况

DISTRIBUTION OF THE CHEMICAL ELEMENTS IN THE WATERS SOUTH OF TAIWAN STRAIT

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;

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.
