Direct correlation of Chinese speleothem d18O and South
China Sea planktonic d18O: Transferring a speleothem
chronology to the benthic marine chronology.
Paleoceanography, 27, PA2203, doi:10.1029/2011PA002268
Orbital tuning of benthic d18O is a common approach for assigning
ages to ocean sediment records. Similar environmental forcing of
the northern South China Sea and the southeast Asian cave regions
allows for transfer of the speleothem d18O radiometric chronology
to the planktonic and benthic d18O records from Ocean Drilling
Program Site 1146, yielding a new chronology with 41 radiometrically
calibrated datums, spanning the past 350 kyr. This approach also
provides for an independent assessment of the accuracy of the
orbitally tuned benthic d18O chronology for the last 350 kyr.
The largest differences relative to the latest chronology
occur in marine isotope stages (MIS) 5.4, 5.5, 6, 7, and 9.3.
Prominent suborbital-scale structure believed to be global
in nature is identified within MIS 5.4 and MIS 7.2. On the basis
of the radiometrically calibrated chronology, the time constant
of the ice sheet is found to be 5.4 kyr at the precession band
(light d18O lags precession minima by -55.4°) and 10.4 kyr at
the obliquity band (light d18O lags obliquity maxima by 57.4°).
These values are significantly shorter than the single 17 kyr
time constant originally estimated by Imbrie et al. (1984),
based primarily on the timing of terminations I and II
and the 15 kyr time constant used by Lisiecki and Raymo (2005).
STUDY NOTES: Foraminiferal stable isotope data (d18O and d13C) from core
ODP1146 in the South China Sea for the last 350 KYrBP. These
data are used to produce a radiometrically-calibrated chronology
for ocean sediments, derived from radiometrically-dated speleothem
records from southeast Asia.
