Abstract
51 diatom samples taken from the piston core PC10 in the Bransfield Strait of West Antarctica were determined by using silica oxygen isotope analysis. The diatoms-based results reveal that the 753 cm long core PC10 was deposited in the area in the last 112.5 ka B.P. , representing 1 - 5 oxygen isotopic stages and including one incomplete glacial/interglacial cycle and a postglacial period. The sedimentation rate in interglacial period seems to be a little higher than that in glacial, owing to the more terrigenous supply by ice-rafting during the interglacial stages.
