The results indicate an average Holocene SST \r\nof about 26.7°C, about 3.6°C increase from LGM to the Holocene, \r\nand higher temperature during MIS 5.5 than the Holocene. These agree \r\nwell with other foraminifer Mg/Ca and Uk37 SST records in this region. \r\nThe Mg/Ca records suggest warmer SSTs during MIS 3 in the northern SCS, \r\ncompared with those in the eastern Pacific. Strong East Asian summer \r\nmonsoon during MIS 3 indicated by paleoclimate records from nearby \r\ncontinents may account for it. Step-wise increases during terminations \r\nare shown in our SST record, and the beginning of deglacial warming \r\noccurs at about 19 ka, which precedes the change of oxygen isotopes, \r\nsuggesting a tropical driven forcing for the SST change in the northern \r\nSCS. This is further supported by a robust semiprecessional cycle \r\ncentering at ~9.1 ka in the spectra of the SST record, which is absent \r\nin that of the oxygen isotopes. However, tropical driven forcing seems \r\nnot to be indicated in another Mg/Ca SST record in the northern SCS \r\n[Oppo, D.W. and Sun, Y.B., 2005. Amplitude and timing of sea-surface \r\ntemperature change in the northern South China Sea: Dynamic link to \r\nthe East Asian monsoon. Geology, 33 (10): 785–788.]. The discrepancy \r\nmay be caused by different post-deposition dissolutions of foraminifer \r\ntests at these two sites. Details about the modification of foraminifer \r\nMg/Ca ratios after burial, however, are not well known in this region, \r\nand further studies are needed. ","author":null,"citation":"Wei, G., W.
