Abstract:

WT5BZ] During CHINARE 15 (12/98-03/99), a 67.5cm lake core had been sampled in Y2 Lake, located in Ardley Island,Antarctica. The concentration of some chemical elements had been analyzed. According to comparative research on elementary character for sediment of Antarctic West Lake, fresh penguin dropping as well as guano soil of Ardley Peninsula and Pacific Island in South China Sea, it presents that the Y2 Lake sediment had been amended by penguin dropping. The result of element cluster analysis shows that the elementary characteristic group for this guano soil includes P、S、Sr、Ba、Cu、Zn、Se、Ca and F, respectively. This provides the base for further interpreting the climatic and environmental event recorded in the sediment.
