Stable isotope ratios of oxygen (18 O/ 16 O) and hydrogen (D/H) in water have long been considered powerful indicators of paleoclimate. The combination of a short expressive 24. Assuming the oxygen to have O18 = 5%o, the CO^ is thus about 6%heavier than the oxygen at the lower temperature, the difference vanishing at about 800 This relationship is in good agreement with the calculations of UBEY (1947), which indicate that COg should be ll%o heavier than oxygen at 327 , with a fractionation factor approaching unity with. O16 is lighter than O18, so it evaporates more easily, leading to water vapor that has a higher proportion of O16. This is the first benthic δ 18 O stack composed of more than three records to extend beyond 850 ka, and we use its improved signal quality to identify 24 new marine isotope stages in the. Isotopes are atoms of the same element that have different numbers of neutrons.
