Palaeoceanographic change in the northeastern South China Sea during the last 15000 years

The Global Thermohaline Paleocirculation

“…The temperature minimum about 4.5 cal ka BP is noted in several sections from the West Pacific marginal seas (Oda and Takemoto 1992;Jian et al 1996;Wei et al 1998). ka BP, that is to the periodicity of about 3 ka (Figs.…”

Early interglacial carbonate-dilution events in the South China Sea: Implications for strengthened typhoon activities over subtropical East Asia

“…It is should be noted that estimates of the CaCO 3 mass accumulation rate (MAR) only include the preserved CaCO 3 fraction but neglect the dissolved part (Loubere et al, 2004). Nevertheless, as the dissolution effect above the SCS CCD only shows moderate changes over the last glacial-interglacial cycle (Wang et al, 1995;Chen et al, 1997;Wei et al, 1998), the CaCO 3 MAR can still be used as an approximate proxy for the paleo-carbonate flux in the SCS.…”

“…Numerous down-core reconstructions suggest that changes in seawater chemistry of the SCS are accordant with that of the open Pacific Ocean during the late Quaternary, which have resulted in relatively well and poor preservation of carbonate during glacials and interglacials, respectively, as well as carbonate preservation maxima during deglacials for the two regions (Wang and Jian, 1992;Thunell et al, 1992;Miao et al, 1994;Wang et al, 1995;Chen et al, 1997;Wei et al, 1998). However, sedimentary carbonate contents (CaCO 3 %) of the SCS sediments show more complicated variations over glacial-interglacial cycles.…”

Paleoenvironmental records from the northern South China Sea since the Last Glacial Maximum

“…The coarse grain fraction decreases from about 6% to about 2% in weight in 220-320 cm depth (Ge et al, 2008), implying strengthened dissolution during this episode. Wei et al (1998) calculated the absolute abundance of whole planktonic foraminifera per gram sediments to monitor the bottom-water dissolution intensity in SCS. They found that the dissolution intensity of the bottom waters was generally low during the last glacial period and deglaciation, but it showed a peak during the early Holocene.…”
