Biogenic silica in surficial sediments of Prydz Bay, Antarctica

The content and distribution of biogenic silica were investigated in sediment cores from Prydz Bay, Antarctica, during the CHINARE-18/21 cruise. The results show that the content of biogenic silica (BSiO2) is ranged from 4.89% to 85.41%, and the average content of biogenic silica is 30.90%, the high...

Description
Summary:The content and distribution of biogenic silica were investigated in sediment cores from Prydz Bay, Antarctica, during the CHINARE-18/21 cruise. The results show that the content of biogenic silica (BSiO2) is ranged from 4.89% to 85.41%, and the average content of biogenic silica is 30.90%, the highest value occurred at the IV-10 station. The profile of BSiO2 in sediment is contrast to that of silicate in the interstitial water. The content of biogenic silica and organic carbon in the surface sediments in the central area of Prydz Bay gyre were much higher than those in other area, and closely related to the Chla content and primary productivity of phytoplankton in the surface water column.
