Relative sea level curves for the South Shetland Islands and Marguerite Bay, Antarctic Peninsula.
This paper presents preliminary relative sea level curves for the Marguerite Bay region and for the South Shetland Islands. The Marguerite Bay curve is constrained by both new and previously published 14C dates on penguin remains and shells, and on two isolation basins dating back to 6500 14C yr BP....

This paper presents preliminary relative sea level curves for the Marguerite Bay region and for the South Shetland Islands.

Extrapolation back to the marine limit yields a minimum deglaciation date for Marguerite Bay of ca 9000 14C yr BP. Analysis of beach clasts suggests that there was a period of increased wave activity, perhaps related to a reduction in summer sea-ice extent, between ca 3500 and ca 2400 14C yr BP.
