Major Pleistocene stages in a carbon perspective: The South China Sea record and its global comparison
Carbon isotope sequences at Ocean Drilling Program Site 1143, South China Sea, reveal a long-term cyclicity of similar to500 kyr that is superimposed on the glacial cycles and is present in long delta(13)C sequences from all oceans. The Quaternary delta(13)C record is punctuated by four delta(13)C m...

Carbon isotope sequences at Ocean Drilling Program Site 1143, South China Sea, reveal a long-term cyclicity of similar to500 kyr that is superimposed on the glacial cycles and is present in long delta(13)C sequences from all oceans. The Quaternary delta(13)C record is punctuated by four delta(13)C maximum events: delta(13)Cmax-I, which began in marine isotope stage (MIS) 3 around 50-60 kyr ago, delta(13)Cmax-II (MIS 13, 0.47-0.53 Ma), delta(13)Cmax-III (MIS 27-29, 0.97-1.04 Ma) and delta(13)Cmax-VI (MIS 53-57, 1.55-1.65 Ma).
