The mid-Pleistocene transition in the subtropical southwest Pacific.
Paleoceanography, 26, PA1211, doi:10.1029/2010PA002019.
Reconstructions of subtropical southwest Pacific climate variability
over the Pleistocene were derived from coupled planktic foraminiferal
d18O-Mg/Ca measurements taken from a southern Coral Sea sediment core.
A clear shift from ~40 kyr to ~100 kyr modes of reconstructed glacial-
interglacial sea surface temperature (SST) variability is seen over
the mid-Pleistocene transition, and these fluctuations are shown to
have remained coherent with the orbital obliquity cycle across the
transition. The likely origin of this strong obliquity signal in
subtropical southwest Pacific SST is shown to be the southern high
latitudes, and comparison with existing SST reconstructions from
the equatorial Pacific is consistent with the communication of the
signal occurring principally by greenhouse gas forcing. In contrast
to the SST reconstruction, regional hydrological cycle variability
(based on the calculated local component of d18Osw change) does not
show significant coherence with obliquity after ~1000 ka.
The decoupling of the SST and hydrological cycle responses over
the mid-Pleistocene transition allows constraints to be placed on
the evolution and extent of orbitally paced fluctuations within
the coupled low-latitude ocean-atmosphere system.
STUDY NOTES: Planktonic foraminiferal (Globigerinoides ruber) stable oxygen
isotope (d18O) measurements. Each sample is based on 12-15
individuals of the G. ruber morphotype picked from the 250-315um
size fraction. Isotope ratios were determined on Thermo Delta+
carbonate mass spectrometer at School of GeoSciences, University
of Edinburgh, analytical reproducibility was 2sd = 0.18 permil
based on standards calibrated to NBS19.
The coupled MD06-3018 planktic foraminiferal Mg/Ca trace metal
record (and associated calibrated SST reconstruction) is also
archived at the World Data Center for Paleoclimatology, in the
data files for Russon et al. (2010), available at:
ftp://ftp.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/russon2010/
The d18Osw record may be derived from these two data-sets using
the method described in Russon et al. (2011).
