英文摘要:
Based upon surveys conducted in November 2012 and June 2013, the distribution and dynamics of aragonite saturation state (Ωarag) were investigated in the southern Yellow Sea (SYS) of China. In summer, surface water Ωaragranged from 2.1–3.8 and enhanced biological production fueled by Changjiang River freshwater input increased Ωaragto 3.8 in the southern SYS. However, subsurface water Ωaragwas < 2.0 in the central SYS. During autumn, surface water Ωaragwas 2.0–2.9, lower than that in summer due to ventilation between surface and low Ωarag(1.0–1.4) subsurface waters in the central SYS. Community respiration and/or aerobic remineralization dominated low Ωaragin subsurface waters, while water stratification influenced the level and scale of acidity accumulation. By the end of this century, waters with Ωarag> 2.0 could disappear from the SYS with increasing atmospheric CO2, while bottom waters Ωaragmay become undersaturated due to the impact of eutrophication. � 2016 Elsevier Ltd
