Sea level change and environmental evolution of coastal lakes in Vestfold Hills, Antarctica

摘要

Ecological and palaeocological studies were carried out in a series of lakes in the Vestfold Hills(68°06'S, 78°06'E)on eastern Antarctic continent. Dynamics types of the lakes in environmental geomorphology and physic-chemistry, as well as features of biological community structures in different lakes were analyzed. Marine macro-and micro-fossils collected from the terraces and beaches surrounding these lakes and determined in ~14C radiocarbon ages to be the Lake Pleistocene, were used as evidences to show the evolutionary processes of the lakes after sea level changes and transgressions since 18000 a B.P..
