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 Ωarag ranged from 2.1-3.8 and enhanced biological production fueled by Changjiang River freshwater input increased Ωarag to 3.8 in the southern SYS. However, subsurface water Ωarag was <2.0 in the central SYS. During autumn, surface water Ωarag was 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 Ωarag in 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 Ωarag may become undersaturated due to the impact of eutrophication.
基于2012年11月和2013年6月开展的调查，对中国黄海（SYS）的文石饱和度状态（Ωarag）的分布和动态变化进行了研究。夏季，表层海水的Ωarag范围为2.1至3.8，长江淡水输入推动的生物生产力增强使南黄海的Ωarag增至3.8。然而，黄海中部的次表层海水Ωarag小于2.0。秋季，表层海水的Ωarag为2.0至2.9，低于夏季，这是由于黄海中部表层海水与低Ωarag（1.0至1.4）的次表层海水之间存在水体交换。群落呼吸和/或好氧再矿化作用主导了次表层海水的低Ωarag状态，而水体分层影响了酸度积累的程度和规模。到本世纪末，随着大气中二氧化碳含量增加，Ωarag>2.0的水体可能会从黄海消失，而由于富营养化的影响，底层海水的Ωarag可能会变得不饱和。
