Glacial/interglacial sea surface temperature changes in the Southwest Pacific ocean over the past 360 ka
International audience The phase relationship between climate parameters during terminations gives insight into deglaciation mechanisms. By combining foraminiferal Mg/Ca and alkenone thermometers with planktonic and benthic foraminiferal delta O-18, we determined the phase relationship between local...

International audience The phase relationship between climate parameters during terminations gives insight into deglaciation mechanisms.
