Abstract
Since its identification nearly fifty years ago Marine Isotope Stage 5 MIS 5 has been placed onto absolute time scales on the basis of three independent approaches Cesare Emiliani who set up the isotope stages Emiliani 1955 depended on uraniumseries dating of the sediments a method that today is regarded as not generally capable of yielding useful precision or accuracy Broecker and van Donk 1970 pioneered the approach of correlating to radiometrically dated marine coral terraces this has been much aided in recent years by improvements in the precision and accuracy of these age determinations that have flowed from the development of thermal ionization mass spectrometry TIMS for uraniumseries dating Edwards et al 1986 The third approach is to use the astronomical record as a guide to the time scale Martinson et al 1987 generated a detailed time scale for MIS 5 using this approach These authors suggested that the overall average error was of the order ±5000 yr although the error would be smaller during interglacial periods with high precessionrelated variability such as MIS5 At that time the suggested confidence limits were smaller than typical values quoted for the radiometric dating of corals typically ±6000 yr Today the accuracy of the time scale of Martinson et al 1987 is challenged by highprecision TIMS dates with quoted uncertainties of the order ±1000 yr or better From the point of view of achieving a better understanding of the last interglacial period the more serious disadvantage of the Martinson et al 1987 time scale is the underlying hypothesis that all the proxy palaeoclimate records represent smoothly varying responses to changes in insolation hence there is no basis for estimating the duration of an extended interval with northern ice sheet volumes static at a size no greater than at present From this point of view the model of Gallée et al 1993 is more promising but that model is not at present sufficiently realistic to provide a reliable independent time scale We have therefore chosen to depict the oxygen isotope record of core MD952042 37°48′N 10°10′W water depth of 3146 m on a time scale Shackleton et al 2001 that is based only on making use of selected radiometric dates obtained from fossil corals to calibrate the isotope record
