“…The phases of South China Sea biogenic opal accumulation (BioOpal) and Arabian Sea G. bulliodes (AS bulloides) contribute much to the large standard deviation, suggesting the possibility of additional variance beyond that contributed by the SM; dissolution may influence the G. bulloides phase while winter monsoon variance may influence the BioOpal phase. In any case, the average phase of À127°agrees very well with the average phase of ten SM proxies (À122°± 16°) previously reported for late Pleistocene records of varying lengths within the past 500 ka from the Arabian Sea (n = 8), South China Sea (n = 1), and the Philippine Sea (n = 1) [Altabet et al, 1995;Chen et al, 2003b;Clemens et al, 1991;Leuschner and Sirocko, 2003;Morley and Heusser, 1997;Reichart et al, 1998;Schmiedl and Leuschner, 2005]. Notably, the only late Pleistocene proxy in disagreement is the Sanbao-Hulu composite speleothem d…”

[1] The Milankovitch paradigm links the timing (phase) of ice volume minima to summer insolation maxima in the hemisphere where ice volume dominates; consistent application of this paradigm dictates that Pliocene ice volume minima should lag Southern Hemisphere summer insolation maxima. We infer the magnitude of this lag on the basis of the phase relationship between equatorial sea surface temperature and benthic d18 O. We infer that Pliocene d18 O minima should lag obliquity maxima by 19°(2.2 ka), broadly consistent with the current global marine d18 O chronology, and precession maxima by 32°(2 ka), a difference of 160°(10.2 ka) relative to the current global marine d18 O chronology. Only in the context of this revision are Pliocene summer and winter monsoon phase relationships consistent with direct orbital forcing across the entire Indo-Asian region, including marine and terrestrial proxies from the Chinese Loess Plateau, the South China Sea, and the Arabian Sea. Strong Pliocene summer and winter monsoons were in phase with one another, strengthened at obliquity minima and precession minima; the summer monsoon was also strengthened at precession maxima, yielding a semiprecession spectral signal. Strong Pliocene monsoons at orbital extremes indicate a direct response to fast physics processes including sensible heating and cooling of the Asian landmass and, for the summer monsoon, the export of latent heat from the southern Indian Ocean. As Northern Hemisphere ice volume grew into the Pleistocene, the timing of strong winter and summer monsoons drifted apart becoming influenced by the combined effects of fast physics and slow physics (ice volume) variables. The phase of strong winter monsoons shifted toward ice maxima, and the phase of strong summer monsoons shifted toward ice minima.

Abstract. The Kuroshio, a western boundary current in the northwestern Pacific, plays a key role in regulating ocean and climate in East Asia. The evolution of the Kuroshio and its branches has been the focus of paleoceanographic studies. In this study, we applied a multiproxy (grain size, planktonic foraminiferal species, δ 18 O, alkenone sea surface temperature (SST) and salinity) reconstruction from sediment core CSH1, which is located at the main axis of the Tsushima Warm Current, a branch of the Kuroshio, in the northern Okinawa Trough (OT). This study, extended the paleoceanographic record of the Kuroshio to Marine Isotope Stage (MIS) 5.1 (∼ 88 ka) from the far northern site in the OT. Planktonic foraminiferal species identified from this core contain warm-water species related to the Kuroshio and coldwater species related to subarctic water mass. The relative abundances of the warm-water species are high during MIS 1 and MIS 5.1, while cold-water species are high during MIS 2. An organic biomarker proxy, alkenone SST measured from core CSH1 ranges between 21 and 25 • C, with higher values during interglacials (MIS 1, 3.3, 5.1) and interstadials and lower values during glacials and Heinrich (H)/stadial events. Sea surface salinity (SSS) and the depth of the thermocline (DOT), reconstructed based on foraminifera isotopes and faunas, indicate dominant Kuroshio responses to an abrupt climate change event recorded in Greenland ice cores and in stalagmites in East China since ∼ 88 ka. The CSH1 SSS appears to be mainly controlled by the local river runoff and the Kuroshio, while the DOT change seems to be closely related to the strength of the Kuroshio and the latitudinal shift of the subarctic frontal zone. Our records suggest that, during MIS 1 and MIS 5.1, while global sea level was high, the Kuroshio was dominant; while during MIS 2, MIS 3 and MIS 4, with a low sea level, stronger winter Asian Monsoon (AM) and a more southerly subarctic front played important roles in governing the hydrographic characteristics in the OT. Spectral analysis of our multiproxy hydrographic records shows a dominant precessional period at ∼ 24 ka. Our hydrographic records, such as SST, SSS and DOT, from a site near the modern Tsushima Warm Current show regional responses corresponding mainly to the global sea level, the Kuroshio, AM and subarctic front, factors which are consistently invoked in the interpretations of other regional records from the OT.

“…Wang and Wang (1990) and Wang et al (1995) reconstructed summer and winter SSTs in the SCS based on foraminifer assemblages, and found that during the LGM, the SCS experienced larger seasonal SST differences and a steeper latitudinal SST gradient than it does presently. Intense glacial cooling in the northern SCS was reported based on foraminifer-and alkenone-based SST records (Huang et al, 1997a, b;Chen and Huang, 1998;Chen et al, 2003). Kienast et al (2001) found a millennium-scale temperature variation that mimics Greenland ice core records.…”

The East Asian winter monsoon variability in response to precession during the past 150 000 yr

et al. 2013

Abstract. The response of the East Asian winter monsoon variability to orbital forcing is still unclear, and hypotheses are controversial. We present a 150 000 yr record of sea surface temperature difference ( SST) between the South China Sea and other Western Pacific Warm Pool regions as a proxy for the intensity of the Asian winter monsoon, because the winter cooling of the South China Sea is caused by the cooling of surface water at the northern margin and the southward advection of cooled water due to winter monsoon winds. The SST showed dominant precession cycles during the past 150 000 yr. The SST varies at precessional band and supports the hypothesis that monsoon is regulated by insolation changes at low-latitudes (Kutzbach, 1981), but contradicts previous suggestions based on marine and loess records that eccentricity controls variability on glacial-interglacial timescales. Maximum winter monsoon intensity corresponds to the May perihelion at precessional band, which is not fully consistent with the Kutzbach model of maximum winter monsoon at the June perihelion. Variation in the East Asian winter monsoon was anti-phased with the Indian summer monsoon, suggesting a linkage of dynamics between these two monsoon systems on an orbital timescale.
