  • Using the 210Pb dating methods in the sediment cores, the modern sedimentation rates in Prydz Bay (Antarctic) are estimated. The results show that the modern sedimentation rates are mainly controlled by marine primary productivity in upper water and benthos in surface sediment. Furthermore, the modern sedimentation rates are also controlled by water stability and submarine topography. The values are 0.47~1.88 mm/a and the average value is 1.06 mm/a. The sedimentation rate is higher than that in Ross Sea but lower than that in Weddell Sea. The highest value occurred in central area of the bay where the sea water is much more stability. The modern sedimentation rates in adjacent continental shelf are much lower.

Abstract: Using the 210Pb dating methods in the sediment cores, the modern sedimentation rates in Prydz Bay (Antarctic) are estimated. The results show that the modern sedimentation rates are mainly controlled by marine primary productivity in upper water and benthos in surface sediment. Furthermore, the modern sedimentation rates are also controlled by water stability and submarine topography. The values are 0.47~1.88 mm/a and the average value is 1.06 mm/a. The sedimentation rate is higher than that in Ross Sea but lower than that in Weddell Sea. The highest value occurred in central area of the bay where the sea water is much more stability. The modern sedimentation rates in adjacent continental shelf are much lower.
