Description:
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 ^1^4C dates on penguin remains and shells, and on two isolation basins dating back to 6500 ^1^4Cyr BP. Extrapolation back to the marine limit yields a minimum deglaciation date for Marguerite Bay of ca 9000 ^1^4Cyr 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 ^1^4Cyr BP. The curve for the South Shetland Islands is derived entirely from published ^1^4C dates from isolation basins and on whalebone, penguin bone and seal bone. The curve shows an initial relative sea level fall, which was interrupted by a period in the mid-Holocene when relative sea level rose to a highstand of between 14.5 and 16m above mean sea level (amsl), before falling again.
