The Ocean Drilling Program Site 1144 (20°3.18’N,117°25.14’E; water depth 2 037 m) from the Northern South China Sea was selected for the measurements on elemental contents in deep-sea sediments of the last 100 ka B.P., by using a nondestructive X-ray fluorescence (XRF) core scanner with an interval of 1cm(time resolution ca.10 a). Compared with the relevant data from Core 17940-2 (20°07.0’N, 117°23.0’E; water depth 17 28 m) recovered during the German SONNE Cruise 95 at almost the same position, the data demonstrated that the elemental ratios such as Ba/Ti and K/Al could be used to indicate the Late Quaternary changes in surface paleoproductivity and chemical weathering, respectively, and hence to reflect the variations of the East Asian summer monsoon. The finds further supported the paleo-climate links between the low latitude oceans and the high latitudes of the southern hemisphere.
