Holocene deglaciation of the Bunger Hills revealed by 14 C measurements on stomach oil deposits in snow petrel colonies
Solidified stomach oil deposits in snow petrel colonies in the Antarctic proved to be suitable for 14 C dating and provide important palaeobiogeographical and palaeoenvironmental information. Following earlier studies in the Untersee oasis (Central Dronning Maud Land) we present here 14 C measuremen...

Solidified stomach oil deposits in snow petrel colonies in the Antarctic proved to be suitable for 14 C dating and provide important palaeobiogeographical and palaeoenvironmental information. Following earlier studies in the Untersee oasis (Central Dronning Maud Land) we present here 14 C measurements on comparable deposits from the Bunger Hills (66°10′S, 101°E). The conventional 14 C age of the basal layer reflects the occupation age of any particular nesting site and therefore a minimum age for the time when this area became ice-free. According to the 14 C results the occupation of the southern part of the Bunger Hills by petrels started about 10000yr ago. The breeding colonies expanded continuously following local ice retreat.
