The Taylor Dome Antarctic 18 O Record and Globally Synchronous Changes in Climate
Abstract The 18 O/ 16 O profile of a 554-m long ice core through Taylor Dome, Antarctica, shows the climate variability of the last glacial–interglacial cycle in detail and extends at least another full cycle. Taylor Dome shares the main features of the Vostok record, including the early climatic op...
