Abstract:
High-resolution delta (super 13) C and delta (super 15) N records of diatom-bound organic matter (delta (super 13) C (sub D) , delta (super 15) N (sub D) ) from ODP site 1094, South of the Polar Front, are combined with reconstructions of summer sea surface temperature and winter sea-ice to establish changes in surface water characteristics associated with the main climatic events of the past 640 ka. 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. (mod. journ. abst.)
