Abstract

Abstract: 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.

Key words: diurnal cycle, dissolved oxygen (DO), chlorophyll, southern slope of the South China Sea

CLC Number:

P735.121
