Similar environmental forcing of \r\nthe northern South China Sea and the southeast Asian cave regions \r\nallows for transfer of the speleothem d18O radiometric chronology \r\nto the planktonic and benthic d18O records from Ocean Drilling \r\nProgram Site 1146, yielding a new chronology with 41 radiometrically \r\ncalibrated datums, spanning the past 350 kyr. This approach also \r\nprovides for an independent assessment of the accuracy of the \r\norbitally tuned benthic d18O chronology for the last 350 kyr. \r\nThe largest differences relative to the latest chronology \r\noccur in marine isotope stages (MIS) 5.4, 5.5, 6, 7, and 9.3. \r\nProminent suborbital-scale structure believed to be global \r\nin nature is identified within MIS 5.4 and MIS 7.2. On the basis \r\nof the radiometrically calibrated chronology, the time constant \r\nof the ice sheet is found to be 5.4 kyr at the precession band \r\n(light d18O lags precession minima by -55.4°) and 10.4 kyr at \r\nthe obliquity band (light d18O lags obliquity maxima by 57.4°). \r\nThese values are significantly shorter than the single 17 kyr \r\ntime constant originally estimated by Imbrie et al. (1984), \r\nbased primarily on the timing of terminations I and II \r\nand the 15 kyr time constant used by Lisiecki and Raymo (2005). \r\n","author":null,"citation":"Caballero-Gill, R.P., S.C.
