摘要: The evolution history of coastal upwelling systems in the East China Sea over late-Holocene are important yet difficult to be characterized. Here, we present ~3000-year temperature records based on both alkenones (UK’37) and glycerol dialkyl tetraethers (TEXH86) from a sedimentary core site southern Sea. By examining similarity difference between down-core TEXH86-derived sea surface temperature, summer monsoon, winter suggest that TEXH86 mainly reflects subsurface water studied site. In this sense, paired would yield an estimation vertical thermal gradient, which provides insight into strength season. Weak periods occurred at 2600–2800 yr BP, 2000–2400 1200–1550 350–750 recent ~100 years. Positive correlations among the...
