The six glacial-interglacial delta (super 13) C (sub D) cycles show excellent agreement with SPECMAP delta (super 18) O and Vostok CO (sub 2) content, suggesting that global physical processes rather than local biological factors were the main influences on delta (super 13) C (sub D) . By contrast, there is weak correspondence between the Vostok dust record and the delta (super 13) C (sub D) and delta (super 15) N (sub D) records.
