Abstract

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 diatom-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.

Key words: Antarctica, Bransfield Strait, diatom oxygen isotope, sedimentology
