Cooling of the South China Sea by the Toba eruption and correlation with other climate proxies similar to 71,000 years ago
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 s...
