Description
Summary:Analyses of Foraminiferal fauna in the core NP93-2 of the Prydz Bay, Antarctica shows that the sediments are rich in Foraminifera in which planktonic Foraminifera make up 26.3% of the total number of Foraminifera and the arenaceous agglutinated benthic Foraminiferal assemblages are prevailing with 57.9% of total number of benthic Foraminiferal. The typical benthic Foraminiferal assemblage of Miliammina arenacea represents an assemblage of deep-water arenaceous agglutinated. Variations of content of warm and cold species of planktonic Foraminifera reflect the paleoclimatic changes and also reveal the paleo-environmental changes in this region and its relationship with the global changes. Other pale-oceanographic and paleo-climatological questions, such as water depth, carbonate dissolution are also discussed.
