ABSTRACT: Correlation of Southern Ocean deep sea sediment core records with ice core records of polar climate delineates with unprecedented detail the relationship between high latitude climate and the ocean’s thermohaline circulation over the last 80,000 years. Our observations suggest that, while North Atlantic Deep Water variability manifests itself clearly in Southern Ocean nutrient proxy records over periods as short as 500 yr, this deep water variability did not promote a direct link between climate variability in the high latitudes of the two hemispheres on millennial timescales. In particular, the proxy records indicate that, on average, northern hemisphere climate fluctuations lagged those of the southern hemisphere by 1,500 yr. GEOGRAPHIC REGION: Southern Ocean PERIOD OF RECORD: 74 KYrBP - present FUNDING SOURCES: DESCRIPTION: This file contains the stable isotope, percent carbonate and percent silica data in core RC11-83. The planktonic values, N. pachyderma (l.c.) and G. bulloides, were generated at S.I.O. using the Carousel-48 automatic carbonate device coupled to a Finnigan MAT 252 mass spectrometer. The benthic values (C. mundulus; previously assigned to P. wuellerstorfi in Charles and Fairbanks, 1992) were generated at LDEO using the same carbonate device coupled to a Finnigan MAT 251 mass spectrometer. Core RC11-83: 41°36'S, 9° 48'E, 4718m water depth.
