In this paper, we outline the need for a coordinated international effort toward the building of an open-access Global Ocean Oxygen Database and ATlas (GO₂DAT) complying with the FAIR principles (Findable, Accessible, Interoperable, and Reusable). GO₂DAT will combine data from the coastal and open ocean, as measured by the chemical Winkler titration method or by sensors (e.g., optodes, electrodes) from Eulerian and Lagrangian platforms (e.g., ships, moorings, profiling floats, gliders, ships of opportunities, marine mammals, cabled observatories). GO₂DAT will further adopt a community-agreed, fully documented metadata format and a consistent quality control (QC) procedure and quality flagging (QF) system. GO₂DAT will serve to support the development of advanced data analysis and biogeochemical models for improving our mapping, understanding and forecasting capabilities for ocean O₂ changes and deoxygenation trends. It will offer the opportunity to develop quality-controlled data synthesis products with unprecedented spatial (vertical and horizontal) and temporal (sub-seasonal to multi-decadal) resolution. These products will support model assessment, improvement and evaluation as well as the development of climate and ocean health indicators. They will further support the decision-making processes associated with the emerging blue economy, the conservation of marine resources and their associated ecosystem services and the development of management tools required by a diverse community of users (e.g., environmental agencies, aquaculture, and fishing sectors). A better knowledge base of the spatial and temporal variations of marine O₂ will improve our understanding of the ocean O₂ budget, and allow better quantification of the Earth’s carbon and heat budgets. With the ever-increasing need to protect and sustainably manage ocean services, GO₂DAT will allow scientists to fully harness the increasing volumes of O₂ data already delivered by the expanding global ocean observing system and enable smooth incorporation of much higher quantities of data from autonomous platforms in the open ocean and coastal areas into comprehensive data products in the years to come. This paper aims at engaging the community (e.g., scientists, data managers, policy makers, service users) toward the development of GO₂DAT within the framework of the UN Global Ocean Oxygen Decade (GOOD) program recently endorsed by IOC-UNESCO. A roadmap toward GO₂DAT is proposed highlighting the efforts needed (e.g., in terms of human resources).

在本文中，我们概述了为构建符合 FAIR 原则（可查找、可访问、可互操作和可重用）的开放式全球海洋氧气数据库和 ATlas (GO ₂ DAT)进行协调的国际努力的必要性。GO ₂ DAT 将结合来自沿海和公海的数据，这些数据通过化学温克勒滴定法或来自欧拉和拉格朗日平台（例如船舶、系泊设备、剖面浮标、滑翔机、机会、海洋哺乳动物、有线天文台）。GO ₂ DAT 将进一步采用社区认可的、完整记录的元数据格式以及一致的质量控制 (QC) 程序和质量标记 (QF) 系统。去₂DAT 将用于支持高级数据分析和生物地球化学模型的开发，以提高我们对海洋 O _{2 的}制图、理解和预测能力变化和脱氧趋势。它将为开发具有前所未有的空间（垂直和水平）和时间（次季节性到多年代际）分辨率的质量控制数据合成产品提供机会。这些产品将支持模型评估、改进和评估以及气候和海洋健康指标的开发。他们将进一步支持与新兴蓝色经济、海洋资源保护及其相关生态系统服务相关的决策过程以及不同用户群体（例如环境机构、水产养殖和渔业部门）所需的管理工具的开发）。更好地了解海洋 O _{2 的}时空变化将提高我们对海洋 O 的理解₂预算，并允许更好地量化地球的碳和热预算。随着保护和可持续管理海洋服务的需求不断增加，GO ₂ DAT 将使科学家能够充分利用不断扩大的全球海洋观测系统已经提供的越来越多的 O ₂数据，并能够顺利整合来自未来几年，公海和沿海地区的自主平台将转化为综合数据产品。本文旨在让社区（例如，科学家、数据管理者、政策制定者、服务用户）在最近由 IOC-UNESCO 批准的联合国全球海洋氧气十年 (GOOD) 计划框架内参与GO ₂ DAT的开发。GO 路线图₂建议 DAT 强调所需的努力（例如，在人力资源方面）。
