“…This chemical signal is consistent with another study, which presented a grass blooming event during the same time period due to weaker summer and stronger winter monsoons (Liew et al 1998). Such a phenomenon has also been reported in neighboring areas, especially the continental shelves of eastern Asia (Sun and Li 1999;Sun et al 2003). Although MIS 2 is a worldwide ice age, a particularly severe period of aridity appears to have affected high latitudinal areas of eastern Asia.…”

ABSTRACT1 Department of Geoscience, National Taiwan University, Taipei, Taiwan, ROC * Corresponding author address: Prof. Yue-Gau Chen, Department of Geoscience, National Taiwan University, Taipei, Taiwan, ROC; E-mail: ygchen@ntu.edu.twOrganic carbon abundance and isotopic composition of sediments in a coastal plain are potentially used to indicate depositional environments and hinterland organic sources. Since Taiwan is located on the eastern margin of the Eurasian continent facing eastward to the Pacific, its geographical position is sensitive to interactions between the sea and land. Changes in the climate have a direct bearing on the costal environment and types of terrestrial plant species that inhabit it. In this study, we sampled two cores drilled from the coastal plain of southwestern Taiwan, and conducted concentration and isotopic analyses of organic carbon.Compared with the generally accepted environmental evolution of Taiwan, our study shows the dominant marine organic source have brought on relatively stable carbon abundance and low level isotopic values for total organic carbon (TOC), whilst input from terrestrial sources attributed to arid-climate-induced C 4 plant blooms make TOC content and δ

“…5). In this context, we consider that the Kuroshio climate in MIS 5.1 is warm but dry, which is detectable from the other episodes in the western Pacific and East Asian paleoclimate (Ikehara and Oshima, 2009;Morley et al, 1991;Sun et al, 2003).…”

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.

“…Compound-specific isotope analysis of both n-alkanoic acid and n-alkane higher plant lipids also indicate that the prevailing occurrence of C3 vegetation. Pollen records from the South China Sea during this time indicate herbs and grasses, with some temperate broad leaf plant types dominated most lowland landscapes (Sun et al 2003). The well-watered and enclosed environment within the Tràng An massif appears to have provided a stable set of conditions for sub-tropical plants despite the climatic downturn.…”
