【摘要】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(BSiO 2 )is ranged from 4.89% to 85.41%,and the average content of biogenic silica is 30.90%,the highest valueoccurred at the IV 10 station.The profile of BSiO 2 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. 【总页数】9页(45-53)
