Abstract

Abstract

The content and distribution of biogenic silica were investigated in sediment cores from the Southern Ocean (Prydz Bay) during the CHINARE-18/21 cruise.The results show that the content of biogenic silica is ranged from 4.89% to 85.41%, and the average content of biogenic silica is 30.90%, the highest value occurs at the IV-10 station.The profile of BSiO₂ is contrast to the profile of SiLicate in the interstitial water.The contents of biogenic silica and organic carbon in the surface sediments in the central area of Prydz Baygyre were much higher than those in other area, and closely related to the Chl a content and primary productivity of phyt oplankton in the surface water column.
