海洋在调节地球碳循环方面发挥着核心作用。监测海洋碳循环如何变化是管理气候变化的基础。卫星遥感是目前我们以高空间和时间分辨率全球和系统地观察海洋表面的最佳工具，过去几十年来，利用卫星数据进行海洋碳研究的研究呈指数增长。卫星观测必须与实地观测和模型相结合，以全面了解海洋碳库和通量。为了帮助优先考虑这一领域的未来研究，组织了一个研讨会，汇集了来自世界各地的主要专家，包括遥感科学家，实地科学家和建模人员，目的是阐明对海洋碳研究现状的集体看法，确定知识差距，并制定未来十年的科学路线图。重点是评价卫星遥感可在哪些方面作出贡献。共有来自南北美洲、欧洲、亚洲、非洲和大洋洲的449名科学家和利益攸关方参加了会议（性别代表性均衡）。会议针对海洋中溶解和颗粒形式的无机和有机碳库，以及碳库之间的主要通量（例如，初级生产）和在界面（例如，海陆空）。极端事件、蓝碳和碳预算也是讨论的主要议题。已确定的新优先事项包括：扩大网络和提高原位观测的质量;改进卫星检索;改进不确定性量化;增进对垂直分布的了解;与模型相结合;改进不同数据来源的时空尺度连接技术;增进对海洋碳循环以及碳库和光库之间相互作用的基本了解。我们还报告了所研究的特定碳池和通量的优先事项，并强调了讨论中出现的问题和关切，例如需要考虑卫星或空间活动的环境影响;卫星在监测海洋二氧化碳清除方法方面可以发挥的作用;基于卫星的信息的经济价值;考虑卫星如何有助于监测其他重要的与气候有关的化合物和元素的循环;促进海洋碳研究的多样性和包容性;汇集致力于地球碳不同方面的社区;最大限度地利用国际机构;遵循开放科学方法;探索远程监测海洋碳的新的创新方法;并利用量子计算。总体而言，本文为未来十年提供了一个全面的科学路线图，说明卫星遥感如何帮助监测海洋碳循环，以及它与陆地和大气等其他领域的联系。

The ocean plays a central role in modulating the Earth’s carbon cycle. Monitoring how the ocean carbon cycle is changing is fundamental to managing climate change. Satellite remote sensing is currently our best tool for viewing the ocean surface globally and systematically, at high spatial and temporal resolutions, and the past few decades have seen an exponential growth in studies utilising satellite data for ocean carbon research. Satellite-based observations must be combined within situobservations and models, to obtain a comprehensive view of ocean carbon pools and fluxes. To help prioritise future research in this area, a workshop was organised that assembled leading experts working on the topic, from around the world, including remote-sensing scientists, field scientists and modellers, with the goal to articulate a collective view of the current status of ocean carbon research, identify gaps in knowledge, and formulate a scientific roadmap for the next decade, with an emphasis on evaluating where satellite remote sensing may contribute. A total of 449 scientists and stakeholders participated (with balanced gender representation), from North and South America, Europe, Asia, Africa, and Oceania. Sessions targeted both inorganic and organic pools of carbon in the ocean, in both dissolved and particulate form, as well as major fluxes of carbon between reservoirs (e.g., primary production) and at interfaces (e.g., air-sea and land–ocean). Extreme events, blue carbon and carbon budgeting were also key topics discussed. Emerging priorities identified include: expanding the networks and quality ofin situobservations; improved satellite retrievals; improved uncertainty quantification; improved understanding of vertical distributions; integration with models; improved techniques to bridge spatial and temporal scales of the different data sources; and improved fundamental understanding of the ocean carbon cycle, and of the interactions among pools of carbon and light. We also report on priorities for the specific pools and fluxes studied, and highlight issues and concerns that arose during discussions, such as the need to consider the environmental impact of satellites or space activities; the role satellites can play in monitoring ocean carbon dioxide removal approaches; economic valuation of the satellite based information; to consider how satellites can contribute to monitoring cycles of other important climatically-relevant compounds and elements; to promote diversity and inclusivity in ocean carbon research; to bring together communities working on different aspects of planetary carbon; maximising use of international bodies; to follow an open science approach; to explore new and innovative ways to remotely monitor ocean carbon; and to harness quantum computing. Overall, this paper provides a comprehensive scientific roadmap for the next decade on how satellite remote sensing could help monitor the ocean carbon cycle, and its links to the other domains, such as terrestrial and atmosphere.
