Abstract

The chemistry of the global ocean is rapidly changing due to the uptake of anthropogenic carbon dioxide (CO2). This process, commonly referred to as ocean acidification (OA), is negatively impacting many marine species and ecosystems. In this study, we combine observations in the global surface ocean collected by NOAA Pacific Marine Environmental Laboratory and Atlantic Oceanographic and Meteorological Laboratory scientists and their national and international colleagues over the past four decades, along with model outputs, to provide a high-resolution, regionally varying view of global surface ocean carbon dioxide fugacity, carbonate ion content, total hydrogen ion content, pH on total scale, and aragonite and calcite saturation states on selected time intervals from 1961 to 2020. We discuss the major roles played by air-sea anthropogenic CO2 uptake, warming, local upwelling processes, and declining buffer capacity in controlling the spatial and temporal variability of these parameters. These changes are occurring rapidly in regions that would normally be considered OA refugia, thus threatening the protection that these regions provide for stocks of sensitive species and increasing the potential for expanding biological impacts.
全球海洋表面酸化:我们从观测中了解到的
由于人为二氧化碳(CO2)的吸收,全球海洋的化学成分正在迅速变化。这一过程通常被称为海洋酸化(OA),对许多海洋物种和生态系统产生了负面影响。在这项研究中,我们结合了NOAA太平洋海洋环境实验室和大西洋海洋学与气象实验室的科学家及其国内和国际同事在过去四十年中收集的全球表层海洋观测数据,以及模式输出,提供了全球表层海洋二氧化碳逸度、碳酸盐离子含量、总氢离子含量、总尺度上的pH值的高分辨率、区域变化视图。1961 - 2020年间文石和方解石的饱和状态。讨论了海气人为CO2吸收、变暖、局部上升流过程和缓冲能力下降在控制这些参数时空变化中的主要作用。这些变化正在通常被认为是野生动物保护区的区域迅速发生,从而威胁到这些区域对敏感物种种群的保护,并增加了扩大生物影响的可能性。

期刊介绍: First published in July 1988, Oceanography is the official magazine of The Oceanography Society. It contains peer-reviewed articles that chronicle all aspects of ocean science and its applications. In addition, Oceanography solicits and publishes news and information, meeting reports, hands-on laboratory exercises, career profiles, book reviews, and shorter, editor-reviewed articles that address public policy and education and how they are affected by science and technology. We encourage submission of short papers to the Breaking Waves section that describe novel approaches to multidisciplinary problems in ocean science.
