摘要OneArgo是Argo计划的重大扩展，该计划为全球海洋上部2公里提供了20年的变革性物理数据。目前的阿尔戈阵列将从三个方面扩大：⑴全球核心：现有的上层海洋测量将扩大到高纬度和边缘海，并扩大对热带和主要海洋盆地西部边界的覆盖; ⑵深海：将对全球50%深度在2 000米以下的海洋进行深海测量; ⑶生物地球化学：将收集溶解氧、pH值、硝酸盐、叶绿素、光学后向散射和辐照度数据，以研究海洋上层的生物地球化学变化以及这些循环对气候变化的响应过程。目前正在通过大规模的区域试点开发这一扩展所需的技术和基础设施，以进一步完善浮标和传感器，并展示这些测量的效用。预计进一步的创新将提高浮标和传感器的性能，并进行必要的分析，以提供研究质量的数据。一个完全全球化的OneArgo应该在5 - 10年内投入运营。
Abstract OneArgo is a major expansion of the Argo program, which has provided two decades of transformative physical data for the upper 2 km of the global ocean. The present Argo array will be expanded in three ways: (1) Global Core: the existing upper ocean measurements will be extended to high latitudes and marginal seas and with enhanced coverage in the tropics and western boundaries of the major ocean basins; (2) Deep: deep ocean measurements will be obtained for the 50% of the global oceans that are below 2,000-m depth; and (3) Biogeochemical: dissolved oxygen, pH, nitrate, chlorophyll, optical backscatter, and irradiance data will be collected to investigate biogeochemical variability of the upper ocean and the processes by which these cycles respond to a changing climate. The technology and infrastructure necessary for this expansion is now being developed through large-scale regional pilots to further refine the floats and sensors and to demonstrate the utility of these measurements. Further innovation is expected to improve the performance of the floats and sensors and to develop the analyses necessary to provide research-quality data. A fully global OneArgo should be operational within 5‐10 years.
