Oxygen and carbon isotope records from benthic and planktonic foraminifera are presented for the past 35,000 years in the northeastern Atlantic. The results support the idea that the last deglaci-ation took place in two major steps (Duplessy et al., 1981 doi:10.1016/0031-0182(81)90096-1; Mix and Ruddiman, 1985 doi:10.1016/0277-3791(85)90015-0; Ruddiman, 1987; Fairbanks, 1989 doi:10.1038/342637a0), and conflict with theories calling for a strong reduction in North Atlantic deep-water formation to explain the abrupt cooling of the Younger Dryas cold period (Broecker et al., 1985 doi:10.1038/315021a0; Rind et al., 1986 doi:10.1007/BF01277044; Broecker et al., 1988 doi:10.1029/PA003i001p00001).
