Near Syowa Station, Antarctica, elevated beaches develop in many of the ice-free coastal areas up to 35m above sea level. These elevated beaches contain many marine organic remains. Their radiocarbon dates can be divided into younger (2000-8000 years B. P.) and older (20000-35000 or more years B. P.) groups. From the former dates the rate of a relative uplift is estimated as 2.5mm/year on the average, possible maximum being 5 to 6mm/year. On the other hand, radiocarbon datings on several kinds of living marine organisms yielded a mean value of 1120 years B. P. This value may be used as a correction factor for radiocarbon dates of marine organic remains in this area.
