利用2004年5月“实验3”号船在南海南部陆架区观测站(109°40′E,06°05′N)连续48h观测得到的温度、溶解氧浓度、叶绿素浓度数据,分析了观测点的叶绿素和溶解氧的垂向分布、日变化特征及其同水温和盐度等物理环境要素的相关关系。结果表明,叶绿素和溶解氧垂向分布与温度有着显著的负相关关系,与盐度有着显著的正相关关系,溶解氧和叶绿素的日变化与温度和盐度的相关性则不显著,跃层深度和海流等对溶解氧的日变化有一定的影响作用。

Ocean temperature, dissolved oxygen (DO), chlorophyll (Chl), ocean current, etc. were observed by R/V Shiyan No.3 during the southern South China Sea exploration in May 2004. These data were used to analyze the oceanographic elements’ influences on the concentrations of DO and Chl. Analysis of the data showed inverse correlation between the vertical distribution of Chl and temperature, and between DO and temperature. The vertical distribution of Chl and DO changed consistent with salinity. The diurnal variations of Chl and DO are influenced by temperature, thermocline and ocean current at the same time.
