| High-resolution carbonate stratigraphy of the deep-sea core MD972151 from the southwestern South China Sea shows millennial-scale variability similar to oxygen isotopic fluctuations recorded in ice cores from Greenland. In a long term of glacial-interglacial scale, carbonate contents in the interglacial time (up to 25 % by weight) were higher than that in the glacial periods (5-15 % by weight). Even for the last glacial, carbonate contents are relatively high in the interstadial events and low in the stadial horizons. This demonstrates clearly that carbonate content in the continental slope above the lysocline in the southwestern South China Sea is primarily controlled by dilution of terrigenous inputs, which in turn is due to sea-level fluctuations in... |

| The Toba tephra layer has been identified in core MD972151 in the southern South China Sea (SCS), northeast of the Indonesia Toba caldera. This affords us an opportunity to directly determine a 1 degreesC cooling for ca.l kyr on the SCS following the Toba eruption (71 Ka) during the marine isotope stage 5a-4 transition, using century-scale sea surface temperature records. This cooling event in the SCS is well correlated with several coeval proxies such as increased East Asia winter monsoon intensity, increased ice-rafted detritus in the North Pacific Ocean sediments, and decreased delta O-18 in Greenland ice core. Such correlation suggests a climate change where cold climate signals originated in the Northern Hemisphere ice sheets, transferred southward by... |
