The Registry of Polar Observing Networks (RoPON) is a powerful resource designed to make high-latitude scientific observation and monitoring more findable, accessible, and connected.

RoPON is a comprehensive catalog of observing systems and related organizations that coordinate, support, or track monitoring activities and infrastructure across the Arctic, Antarctic, and Southern Oceans. It brings together information that has traditionally been dispersed across multiple platforms, helping to create a clearer and more integrated picture of polar observing efforts.

The registry includes a wide range of networks involved in observing, research, infrastructure, and data management, such as SIOS, GTN-P, and NASA ABoVE, which play key roles in coordinating and supporting observations in polar regions.

Each observing network in RoPON is presented with detailed information, including a description, contact details, and links, as well as its observational scope, geographic extent, associated organizations, and related data repositories. The registry also indicates whether networks maintain inventories of observing assets, such as research stations, mobile platforms, satellites, campaigns, and initiatives, and whether these inventories are publicly accessible.

In addition to observing networks, RoPON also displays discovery portals and inventories that are not observing networks per se, but which compile and share structured information about observing activities and infrastructure, such as ARMAP, AOV, ISAAFFIK, and Polardex, further enhancing access to polar data and resources.

Designed as a distributed and evolving platform, RoPON allows authorized representatives of observing networks to log in and update or expand their information through a dedicated dashboard. The platform continues to grow and evolve, incorporating user feedback, real-world use cases, and a robust metadata framework.
