OneArgo: an integrated global, full depth and multidisciplinary ocean observing array for beyond 2020

The Argo Steering Team

Arctic Ocean, Create a digital representation of the Ocean, Develop a sustainable and equitable ocean economy, Increase community resilience to ocean hazards, Indian Ocean, North Atlantic Ocean, North Pacific Ocean, Project, Protect and restore ecosystems and biodiversity, Skills, knowledge and technology for all, South Atlantic Ocean, South Pacific Ocean, Southern Ocean, Sustainably feed the global population, Understand and beat marine pollution

OneArgo will transform the revolutionary ‘core' Argo array (which tracks the upper ocean physical state) to one that has truly global reach, including the polar oceans and marginal seas, extending to the full ocean depth and including ocean biogeochemical measurements.

Through Argo’s novel data management system, all data will be freely shared in real-time with a high-quality version delivered within 12 months. Implementing OneArgo will greatly increase Argo’s already remarkable impact on ocean and climate services, predictions and research, and enable ground-breaking developments in understanding ocean ecosystems, forecasting ocean productivity and constraining the global carbon and energy budgets.
