Variability of Southwest Indian summer monsoon precipitation
during the Bølling-Ållerød.
Geology, Vol. 33, pp. 813-816, October, 2005,
doi:10.1130/G21498.1
We have generated a high-resolution (<20 yr) 230Th-dated stalagmite
oxygen isotope record from Timta Cave in the western Himalaya in
India that documents Southwest Indian summer monsoon (ISM)
precipitation variations during the Bølling-Ållerød interstadial
from 15.2 to 11.7 ka. Compared with the glacial and Younger Dryas,
ISM precipitation was enhanced during the Bølling-Ållerød.
ISM precipitation was apparently coupled to variations in the
East Asian monsoon and North Atlantic climate on millennial and
multicentennial time scales during the deglaciation. Analyses of
a high growth rate interval (<2.5 yr resolution) encompassing the
late Bølling-early Ållerød suggest that multidecadal monsoon
variability was an important aspect of ISM behavior at that time.
The frequency spectrum of ISM precipitation during this time
interval is similar to that of the D14C record and other ISM
precipitation records during the latest Holocene. This raises
the hypothesis that multidecadal climate dynamics during the
late Bølling-early Ållerød may have been similar to those that
operated during the last several millennia, even though the
boundary conditions of these two time intervals were very different.
STUDY NOTES: High resolution oxygen isotope data (d18O) from a stalagmite
collected in Timta Cave, India covering the Bølling-Ållerød
interstadial (15.2 to 11.7 ka).
