Accelerating Ocean Knowledge and Governance: From OneArgo’s Global Vision to Argo-Dome’s Regional Action
Jun 4, 2025 — 10:30 am - 11:45 AMINSPIRE Area
The ocean drives Earth’s climate, sustains vital ecosystems, and supports the global economy. Yet, much of it remains under-observed, limiting our ability to improve weather forecasts, ensure maritime safety, secure food supplies, strengthen climate resilience, and safeguard human well-being.
Since the early 2000s, the global Argo program has transformed ocean monitoring by deploying a vast network of autonomous floats that measure temperature and salinity up to 2,000 meters deep in real time, providing open-access data worldwide. Building on this success, OneArgo aims to expand the Argo program to include full-depth, polar, and biogeochemical observations - covering the carbon cycle and ocean health. By 2030, OneArgo promises to unlock new insights into the ocean and climate, enhance forecasting at regional and global scales, and democratize ocean data for all nations.
With input from scientists, modelers, and end-users, this session will explore the current status and future directions of the OneArgo initiative, highlighting its essential role in providing actionable ocean intelligence and supporting science-based marine policy amid the climate crisis. The session will conclude with showcase the use of Argo technology for three-dimensional dynamic management in the Eastern Tropical Pacific’s Thermal Dome—a biodiversity hotspot in Areas Beyond National Jurisdiction (ABNJ). This example illustrates how sustained ocean observation can enhance High Seas governance in line with the objectives of the Biodiversity Beyond National Jurisdiction (BBNJ) Treaty.
