Silica oxygen isotope record of core PC10 diatoms from the Bransfield Strait, Antarctica and its application in sedimentology
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 isoto...

| Summary: | 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. |
