过去四十年来，在理解和量化水库之间的碳储量和流动方面取得了重大进展。然而，影响碳循环的复杂海洋过程的知识很大程度上被分为物理化学和生物学研究。沿海和公海碳过程之间的联系也得到了充分研究。为了充分了解海洋碳循环及其未来的预期变化，需要采用全面、综合的方法进行海洋碳循环研究。特别是，需要更定量地了解生物过程如何与公海和沿海水域的物理和化学驱动因素相互作用。此外，需要在当前的社会经济背景和未来几十年的巨大预期变化的背景下理解碳循环。为了解决这些问题，综合海洋碳研究（IOC-R）这一正式的IOC工作组于2018年成立。该工作组是对联合国海洋科学促进可持续发展十年（2021-2030）“十年”的回应。 IOC-R 将为十年总体实施计划的科学要素做出贡献。该实施计划是一个高级别框架，用于指导海洋科学能够更有效地为实现十年所概述的社会成果做出贡献的行动。 IOC-R通过研究和观测目标的组合策略解决海洋碳研究的关键问题，重点关注实施计划的海洋碳循环部分。该研究将围绕 2019 年 10 月 28 日至 30 日在法国巴黎 IOC-UNESCO 总部举行的首届综合海洋碳研究专家研讨会上提出的四个关键问题展开： 1) 海洋对人为二氧化碳 (CO 2) 的吸收是否会继续以非生物过程为主？ 2）生物在海洋碳循环中的作用是什么？ 3）陆地-海洋连续体之间的碳交换是什么以及它们如何随时间演变？ 4）人类如何改变海洋碳循环，有何反馈？
Significant advancements have been made over the past four decades in understanding and quantifying the stocks and flows of carbon between the reservoirs. However, knowledge of the complex oceanic processes influencing the carbon cycle has been largely compartmentalized into physico-chemical and biological studies. The connections between coastal and open-ocean carbon processes have also been understudied. To fully appreciate the ocean carbon cycle, and its anticipated changes in the future, a holistic and integrated approach to ocean carbon cycle research is needed. In particular, a greater quantitative understanding of how biological processes interact with the physical and chemical drivers in the open ocean and in coastal waters is needed. Moreover, the carbon cycle needs to be understood in the current socio-economic context and large anticipated changes in the next decades. To address these issues, the Integrated Ocean Carbon Research (IOC-R), a formal IOC working group, was formed in 2018. The working group is a response to the UN Decade of Ocean Science for Sustainable Development 2021-2030,“the Decade”. The IOC-R will contribute to the science elements of an overarching Implementation Plan for the Decade. The Implementation Plan is a high-level framework to guide actions by which ocean science can more effectively deliver its contribution to achieving the societal outcomes outlined for the Decade. The IOC-R focusses the ocean carbon cycle component of the Implementation Plan by addressing key issues in ocean carbon research through a combined strategy of research and observational goals. The research will be framed by four key questions that were formulated at the inaugural Expert Workshop on Integrated Ocean Carbon Research at the IOC-UNESCO Headquarters in Paris, France on Oct. 28-30, 2019: 1) Will the ocean uptake of anthropogenic carbon dioxide (CO 2) continue as primarily an abiotic process? 2) What is the role of biology in the ocean carbon cycle? 3) What are the exchanges of carbon between the land-ocean continuum and how are they evolving over time? 4) How are humans altering the ocean carbon cycle, and what are the feedbacks?
