Paleoenvironmental changes during the last 8400 years in the southern Yellow Sea: Benthic foraminiferal and stable isotopic evidence

Molecular identification of Ammonia and Elphidium species (Foraminifera, Rotaliida) from the Kiel Fjord (SW Baltic Sea) with rDNA sequences

“…Eight of these phylotypes can be assigned to described species on the basis of morphological features, whereas the extensive use of the name A. beccarii should be abandoned (Hayward et al 2004). Furthermore, the phylotype T6 has a disjunct distribution, in the Wadden Sea and marginal seas off Japan and northern China, where the names Ammonia aomoriensis (Asano 1951) and Ammonia ''beccarii'' forma 1 have been used (Nomura and Seto 1992;Xiang et al 2008;Takata et al 2006) The name A. aomoriensis was therefore proposed for the phylotype T6 (Hayward et al 2004).…”

“…Their tests are readily preserved in the fossil record and serve as proxies for paleoenvironmental analyses (e.g. Kubisch and Schönfeld 1985;Poignant et al 2000;Xiang et al 2008). …”

Reconstruction of the East China Sea palaeoenvironment at 16 ka by comparison of fossil and modern Faviidae corals from the Ryukyus, southwestern Japan

“…In the area off the Miyako Islands, mean SSS fluctuates slightly around 34 practical salinity units (psu), with highest and lowest values in January and July, respectively (Levitus and Boyer, 1994;Chen et al, 2006). The Kuroshio Current transport also varies on interannual timescales, with less transport during El Niñ o years and more during La Niñ a years, but in the modern ocean seasonal variations are greater than those that occur on interannual timescales (Xiang et al, 2008). The fossil coral sample MYK90 was collected as part of the research project 'Techniques for reconstruction and interpretation of reservoir development' conducted by the Technology Research Center (TRC), Japan National Oil Corporation (JNOC; currently the Japan Oil, Gas and Metals National Corporation) (Honda et al, 1993;Sasaki et al, 2006).…”

“…Although the peak ice volume occurred between 22 and 19 cal. ka BP (Yokoyama et al, 2000), large, thick ice sheets continued to exist until after the start of the last deglacial warming trend at 14.8 ka (Xiang et al, 2008). The glacial ice sheet growth changed both the global sea level and the global seawater salinity.…”

Geochemistry of Middle Holocene sediments from south Yellow Sea: Implications to provenance and climate change

“…Analyses of the SYS sediments used to focus on provenance (Youn and Kim, 2011;Yang and Youn, 2007;Qin et al, 1989;Ren and Shi, 1986;Chough and Kim, 1981). However, recently, environment and climate change have been inferred through analyzing the sediment properties (e.g., grain size, geochemical compositions, micropaleontology, magnetics) of the mud sediments in the middle and eastern Yellow Sea (Liu et al, 2009;Xiang et al, 2008;Ge et al, 2005;Cheng et al, 2001;Kim and Kennett, 1998). Sediments of the western shelf of the southern Yellow Sea are mainly supplied by the Yellow and Yangtze rivers (Alexander et al, 1991;Milliman et al, 1985a, b), so that they contain information on environment and climate changes in the catchments of these rivers, i.e., central and northern China.…”
