ABSTRACT: 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. GEOGRAPHIC REGION: Tropical Western Pacific PERIOD OF RECORD: 1543KYrBP - present FUNDING SOURCES: UK Natural Environment Research Council (NERC), French Zonéco program, CNFE, IPEV, and IRD. DESCRIPTION: 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). Core MD06-3018: 23°00'11"S; 166°08'58"E, 2470m water depth. DATA: 1.
