SOOSmap: Your gateway to Antarctic data discovery

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.
