Decade Coordination Office for Ocean Observing

Coordinating ocean observing for the Ocean Decade.

We work with GOOS and partners across Challenge 7 to build a sustained observing system, from coastlines to the deep ocean, that delivers accessible, timely and actionable data.

8,561observing platforms reported a position in the 30 days to 17 October 2026.

  • Argo profiling floats: 4,801
  • Drifting and moored buoys (DBCP): 1,976
  • Ships (SOT): 1,517

What we do

Coordinating Ocean Decade Challenge 7

Ocean Decade Challenge 7 calls for a sustainable ocean observing system across all ocean basins that delivers accessible, timely and actionable data and information to all users.

Hosted by UCAR's Center for Ocean Leadership, DCO-OO connects the many Decade Actions working toward that goal, alongside GOOS and partners, so the coordination lasts beyond 2030.

  • Blue food and ocean economy

    Information that supports food from the sea and a sustainable ocean economy.

  • GOOS beyond 2030

    Lifting observing capacity and leaving a practical legacy for GOOS after the Decade.
