Long-chain alkenones were detected in samples of sea surface sediments from the Chukchi Sea and the Bering Sea areas,the Arctic Pole.The analysis result indicates that C37:3 methylketone is predominate in the long-chain alkenones from the Chukchi and Bering Sea sediments.The abundance of C37 to C39 unsaturated alkenones changes in an order of C37 > C38 > C39.Based on ∑C37/∑C38 ratio,the detected organism precursors of the long-chain alkenones are mainly coccolithophrid (Emiliania huxleyi).By the calibration relationship between U37k and U37k indices,the sea surface paleotemperature in these seas is estimated.The estimated values of U37k vary from 4.147℃ to 5.706℃,with a mean value of 5.092℃.
