Fossil dripwater in stalagmites reveals Holocene temperature
and rainfall variation in Amazonia.
Earth and Planetary Science Letters, Vol. 275, Issues 1-2,
pp. 54-60, 30 October 2008. doi:10.1016/j.epsl.2008.07.060
Most proxy records used for reconstruction of Holocene climate
of Amazonia are unable to quantitatively distinguish between
the effect of temperature and rainfall amounts. We present a new
isotope technique applied to a ~13,500 yr stalagmite archive from
Peruvian Amazonia. By analysing the coupled isotope composition
of fossil dripwater trapped in stalagmite fluid inclusions,
and that of the calcite hosting the fluid inclusions, we were able
to calculate independent paleotemperatures and rainfall amounts.
This stalagmite record shows that Holocene climate variation was
controlled by orbitally-forced Southward migration of the Inter
Tropical Convergence Zone. While temperature remained constant,
isotope variation of rainwater, reflected in fluid inclusion water
d18O composition, suggests a ~15-30% increase in convective rainfall
through the Holocene. A comparison of the low-land Peruvian fluid
inclusion record with the high Andean Huascaran ice core record
shows a constant ~12‰ offset of d18O curves for the Holocene,
suggesting that Andean vertical temperature gradients (lapse rates)
did not vary much over the last 9000 years. During the Younger Dryas
interval, however, the offset of d18O values was much higher than
in the Holocene. This may be attributed to a relative drop in air
temperatures in the highlands (higher lapse rate), caused by long
distance teleconnections to climate perturbations in the North
Atlantic. In a wider perspective, fluid inclusion isotope analysis
drastically improves paleotemperature reconstructions based on
speleothem calcite d18O data, because it provides the d18O value
of drip water through time, which is usually the most important
unknown in paleotemperature equations.
STUDY NOTES: Stalagmite fluid inclusion and calcite oxygen isotope record from an
Amazon Basin cave, dated by U-Th. Data consist of fluid inclusion
d18O and dH2 and calcite d18O data from two stalagmites collected in
Cueva del Tigre Perdido, Peru.
