由于臭氧化引起的酸化，预计早在本世纪中叶，高纬度地区的表层沃茨中的文石就会持续不饱和。在某些北方极地海洋的表层和浅层沃茨中，已经观察到季节性的文石不饱和现象。钙化的海洋生物，包括翼足类、有孔虫、冷水珊瑚、海胆、软体动物和珊瑚藻，是高纬度地区丰富群落的重要组成部分，人们认为，随着海洋酸化的加剧，它们面临着危险。在今后几十年中，气温上升和物种入侵的趋势，加上海洋逐步酸化，预计将越来越多地影响南极和北极的浮游和底栖海洋群落。这些变化的速度和幅度突出表明，迫切需要加强极地和次极地海洋的海洋酸度研究和监测工作。
Owing to anthropogenic-induced acidification, surface waters of the high latitudes are projected to become persistently undersaturated with respect to aragonite as early as mid-century. Seasonal aragonite undersaturation in surface and shallow subsurface waters of some northern polar seas has already been observed. Calcified marine organisms, including thecosomatous pteropods, foraminifers, cold-water corals, sea urchins, molluscs, and coralline algae, make up significant components of the rich communities in high latitudes, and they are thought to be at risk with increasing ocean acidification. Over the next decades, trends of rising temperatures and species invasions coupled with progressive ocean acidification are expected to increasingly influence both planktonic and benthic marine communities of Antarctica and the Arctic. The rate and magnitude of these changes underscore the urgent need for increased efforts in ocean acidity research and monitoring in polar and subpolar seas.
