Depth Distributions of d18O and Changes in Mixed Layer Thickness in the South China Sea

Abstract
This study focuses on analyzing depth distributions of d18O and changes in mixed layer thickness in the South China Sea (SCS). The oxygen isotopic compositions of the samples collected were determined using the Epstein-Mayeda (1953). The overall precision of the d18OSMOW measurements is +0.1‰. Our data suggest that depth changes of average d18OSMOW of seawater in the SCS as follows: the average d18OSMOW values for the surface (0-100m) is 0.02‰; subsurface (100-400m) is 0.2‰; intermediate (400-1500m) is ¡V0.03‰ and deep waters (>1500m) is ¡V0.06‰. The effect of monsoon on the mixed layer in the SCS water is evident as the increases in the mixed layer is always coincident with the northeast monsoon in winter. Furthermore, the d18OSMOW values are correlated linearly with the mixed layer thickness. In other words, the lower d18OSMOW values of seawater are, the less the thickness of mixed layer is.
