Inter-hemispheric asymmetry in the early Pleistocene Pacific warm pool.
Geophysical Research Letters, Vol. 37, L11601, doi:10.1029/2010GL043191
The position of the southern boundary of the Pacific warm pool
is shown to have been stable since the early Pleistocene, based
upon a planktic foraminiferal Mg/Ca-derived reconstruction of
subtropical sea surface temperature in the Coral Sea. This
contrasts with previous reconstructions showing warm pool
contraction from the north and east and means that the early
Pleistocene warm pool was more hemispherically asymmetric
than its present configuration. The latter was not established
until ~1Ma, supporting a strengthening of the northern Hadley Cell,
which was not replicated in its southern counterpart, prior to the
Mid-Pleistocene Transition.
STUDY NOTES: Planktonic foraminiferal (Globigerinoides ruber) measurements
of Mg/Ca and associated calibrated SST values using the Anand
et al. (2003) calibration for the 250-350um size fraction
(without a pre-assumed pre-exponential coefficient).
Each sample is based on 35-40 individuals of the G. ruber
morphotype picked from the 250-315um size fraction.
Sample preparation follows the method of Barker et al. (2003)
and Mg/Ca determination by ICP-OES that of de Villiers et al. (2002).
