南大洋因具有较强的CO2吸收能力,其海洋酸化问题较全球其他海域尤为突出。文石饱和度(Ω文石)作为衡量海洋酸化状况的指标之一,在评估海洋钙质生物的生存环境中发挥着重要的作用。然而,由于南大洋复杂的气候环境,在这一区域开展海洋酸化和Ω文石的研究异常困难。因此,为了便于今后在南极周边海域开展海洋酸化的研究,了解南大洋海洋酸化的现状,对南极周边海域Ω文石的研究进行了概述。南大洋表层海水Ω文石具有明显的时空分布特征,主要体现为近岸海域Ω文石值一般低于开阔大洋海域,且具有夏季高、冬季低的季节变化特征。在垂向分布上,海水Ω文石值呈现由表层向深层递减的趋势。此外,由于受到深层水团的通风和涌升的影响,南大洋Ω文石等值线深度随纬度升高而变浅。海水Ω文石受海冰融化、海—气CO2交换、浮游植物活动以及水文等诸多因素的共同控制。最后,对南大洋未来海洋酸化的变化趋势进行展望,提出亟需解决的科学问题。

The Southern Ocean is a strong sink for atmospheric CO2, making it especially vulnerable to ocean acidification (OA). The aragonite saturation state (Ωarg) of seawater has been used as an index for the estimation of OA, which plays a critical role in evaluating the living environment of marine calcified organisms. However, it is very difficult to perform the studies of OA and Ωarg in the Southern Ocean due to its harsh climate. Therefore, in order to better understand the OA and its further influences, the advances of Ωarg studies were summarized in the oceans surrounding the Antarctica. Significant spatial and temporal variations of surface seawater Ωarg are demonstrated in the Southern Ocean. In general, the surface seawater Ωarg shows a lower value in the off-shore areas than in the open oceans. And, Ωarg also exhibits a strong seasonal cycle with a higher value in summer than in winter. The distributions of Ωarg in vertical water column generally present a declining tendency from surface to bottom. In addition, the shoaling of Ωarg horizon at high latitude could be attributed to the ventilation and upwelling of deep waters in the Southern Ocean. There are many factors that could impact the Ωarg in the Southern Ocean, including sea ice melting, sea-air CO2 exchange, biological activities and hydrological processes, etc. Finally, the future changes and key scientific problems of OA in the Southern Ocean are proposed.
