Wang, X., A.S. Auler, R.L. Edwards, H. Cheng, E. Ito, Y. Wang, X. Kong, and M. Solheid. 2007. Millennial-scale precipitation changes in southern Brazil over the past 90,000 years. Geophys. Res. Lett., 34, L23701. doi:10.1029/2007GL031149.
A U-Th dated 90,000 year-long speleothem oxygen isotope record
from southern Brazil anti-correlates remarkably with the cave
calcite records from eastern China, but positively correlates
with the speleothem record from northeastern Brazil, suggesting
an interhemispheric anti-phasing of rainfall on both millennial
and orbital timescales, likely related to displacement in the
mean position of the intertropical convergence zone and
associated asymmetry in Hadley circulation. The phase
relationships among these records are consistent with the
hypothesis that abrupt climate events during the last glacial
period are triggered by oceanic circulation changes in the
high latitudes and enhanced by tropical feedbacks.
STUDY NOTES: DESCRIPTION:
90 KYr speleothem stable isotope record from stalagmite BTV3A,
Botuverá Cave, southern Brazil. BTV3A is 24cm long, dated by
16 U-Th samples, and grew continuously for the last 90kyr
with no detectable hiatuses.
