南大洋酸化指标——海水文石饱和度变异的研究进展
发布时间：2019-06-10 07:30
【摘要】：南大洋因具有较强的CO_2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CO_2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。
[Abstract]:Because of its strong CO_2 absorption capacity, the ocean acidizing problem of the Southern Ocean is more prominent than that of other seas in the world. As one of the indexes to measure the status of ocean acidizing, aragonite saturation plays an important role in evaluating the living environment of marine calcareous organisms. However, due to the complex climate and environment of the Southern Ocean, it is very difficult to carry out the study of ocean acidizing and 惟 _ (aragonite) in this area. Therefore, in order to facilitate the study of ocean acidizing in the waters around Antarctica in the future and to understand the present situation of ocean acidizing in the Southern Ocean, the study of omphacite in the waters around Antarctica is summarized. The surface sea water of the Southern Ocean has obvious temporal and spatial distribution characteristics, which is mainly reflected in the fact that the omarite value in the inshore sea area is generally lower than that in the open ocean area, and has the characteristics of high summer and low seasonal variation in winter. In the vertical distribution, the omarite value of seawater decreases from the surface to the deep layer. In addition, due to the influence of ventilation and surge of deep water masses, the depth of omphite isoline in the Southern Ocean becomes shallow with the increase of latitude. Sea water 惟 _ (aragonite) is controlled by many factors, such as melting sea ice, sea-air CO _ 2 exchange, phytoplankton activity, hydrological and so on. Finally, the future trend of ocean acidizing in the Southern Ocean is prospected, and the scientific problems that need to be solved urgently are put forward.
