南极普里兹湾柱样有孔虫研究

南极普里兹湾柱样ＮＰ９３２含有较多的有孔虫，其中浮游类占２６．３％，底栖类中砂质胶结类占５７．９％，为该柱的优势类群。底栖有孔虫组合以Ｍｉｌｉａｍｍｉｎａａｒｅｎａｃｅａ为典型代表，显示了深水砂质胶结相的面貌。浮游类群中暖与冷水种群的丰度变化，反映了所在海区气温的变化

FORAMINIFERA OF DOWNCORE FROM THE PRYDZ BAY,ANTARCTICA

Foraminifera fauna are analysed in the downcore NP932 from Prydz Bay,Antarctica. Foraminifera fauna are rich in the sediment of downcore NP932. Planktonic foraminifera group make up 26.3%(21 species) of the total number of Foraminifera. The benthonic foraminifera occupied 73.3%( 57 species) of total number of Foraminifera in the region. Among them the agglutinated group of benthonic foraminifera occupied 57.9%, which is mainly benthonic in the foraminifera assemblages and Miliammina arenacea is most important. It reflects continental upslope deep water bioface. Content of the warm and cold species of planktonic foraminifera reflects the change of climate. The other paleoceanology and paleoclimate questions such as water depth, carbonate dissolution etc. are also discussed.
