Abstract

The compounds of sterols such as C27, C28, C29 and C30 are recorded from C-8 core of the Chukchi Sea. The double bond position is located at 5-, 5, 22 as well as 22-, 24-. The compound of sterols such as C27, C28, C29 are recorded from B2-9 core of the Bering Sea. The double bond position is located at 5-, 5, 22 as well as 22. The composition characteristics of sterols indicate that the substance is mainly contributed by the terrigenous origin and marine silicate organism. The results are also suggest that the record of abnormal sterols from the surface sediments (2 - 0 cm) in the Chukchi Sea and the Bering Sea represents the period from 1980s to the late 1990s. The strong signal of the Arctic warming is preserved in the sediments, which indicates the eco-environmental change responding to climatic effect of circumjacent.
