Abstract:

We studied molecular geochemical compositions of penguin ornithogenic sediment DG2 from Gardner Island,Vestfold Hills,East Antarctica. The results showed that the aliphatic hydrocarbons mainly consisted of short-chain n-alkanes which likely derived from freshwater algae and bacteria. Meanwhile,the even-carbon fatty acids,such as n-C16,n-C18 and n-C24,dominated alkenoic acids and they principally originated from bacteria,freshwater moss or zooplankton. However,unsaturated fatty acids were predominated by C18...

Key words: penguin ornithogenic sediment, fecal sterol, fatty acid, East Antarctica.
