SOOSmap: Your gateway to Antarctic data discovery Elem Sci Anth

The Southern Ocean is central to global ocean mixing and climate regulation via its disproportionate uptake of human-induced heat and carbon dioxide, yet the underlying processes are still poorly understood. Coordinated and sustained effort in observation and modelling of Southern Ocean processes in the past, present and future is therefore critical for understanding and mitigating the changes underway. Free and equitable access to Southern Ocean data is a fundamental prerequisite to meeting this objective. Here, we present a tool for discovery of, and access to, existing Southern Ocean data—SOOSmap, Version 2 (soosmap.aq). SOOSmap is a gateway to physical, biogeochemical and biological open-access data, free for anyone to use, from ocean science experts to classroom students. SOOSmap was developed in a collaboration of the Southern Ocean Observing System and the European Marine Observations and Data Network Physics project, with the aim to provide an easy to use one-stop-shop for Southern Ocean data held in repositories around the world. In this article, we illustrate the different methods of data access within SOOSmap, describe SOOSmap in the context of other polar data resources and initiatives, demonstrate how SOOSmap can be put into practice by a variety of stakeholders, and instruct users on how they can get involved in the SOOS community and contribute new data to SOOSmap, which is fundamental for this tool to continue to be useful for informing policy and decision-making about changes occurring in the Southern Ocean.

南大洋（Southern Ocean）是全球海洋混合与气候调控的核心区域，其吸收人为热与二氧化碳的能力远超平均水平，但其背后的调控机制仍有待深入解析。因此，针对南大洋过程开展跨时空（过去、现在与未来）的协同观测与模拟研究，对理解当前变化并制定减缓策略至关重要。免费且公平地获取南大洋数据，是达成这一目标的基本前提。本文介绍一款用于发现并获取现有南大洋数据的工具——SOOSmap 2.0版（访问地址：soosmap.aq）。SOOSmap是物理、生物地球化学与生物开放获取数据的统一门户，面向所有人群免费开放，从海洋科学专家到课堂学生均可自由使用。SOOSmap由南大洋观测系统（Southern Ocean Observing System）与欧洲海洋观测与数据网络物理项目联合开发，旨在为全球各地数据存储库中存储的南大洋数据提供便捷易用的一站式服务平台。本文详细阐述了SOOSmap内置的多种数据获取方式，结合其他极地数据资源与相关计划的背景介绍了SOOSmap的定位，演示了各类利益相关方如何实际应用SOOSmap，并指导用户如何加入SOOS社区、为SOOSmap贡献新数据——这也是该工具能够持续为南大洋变化相关政策制定与决策提供科学参考的核心基础。
