Summary
Abstract: [Abstract from data documentation]
Variations in tropical sea surface temperature patterns and the
phasing relative to climate change in higher-latitudes provide insight
into the mechanisms of climate change on both orbital and shorter
time-scales. Here, we present well-dated, high-resolution records of
planktonic foraminiferal 18O and Mg/Ca-based SST spanning the last
deglaciation from the Sulu Sea, located in the western equatorial
Pacific. The results indicate that the last glacial maximum was 2.3 B1
0.5B0C cooler than present in the Sulu Sea with a concomitant decrease
in sea surface salinity. The similarity between variations in surface
salinity in the Sulu Sea, the western and eastern equatorial Pacific,
and the Greenland ice-core record suggests that the observed changes
in salinity reflect large-scale rearrangement of atmospheric patterns,
which were coherent and synchronous throughout the Northern
Hemisphere. The results suggest that the glacial equatorial Pacific
climate was strongly influenced by both tropical, and extra-tropical
forcing, although it is not clear whether interannual (ENSO)
variability is a good analogue of glacial-interglacial climate change.

Foraminiferal oxygen isotope data and Mg/Ca from core MD97-2141,
Latitude 8.8 N, Longitude 121.3 E, Water depth 3633 m.

Data includes stratigraphic information for d18O Globigerinoides
ruber, white form, 212-250u.
