Deployment at the Edge of Winter
In Northeast Greenland, researchers release an Argo float just before Arctic winter drives them away. While humans retreat, the robot descends into icy water to continue the work.

 

A Global Ocean Watch
The float joins more than 4,000 autonomous instruments worldwide, forming the Argo Program—an international effort to observe the ocean below the surface.

 

Why the Arctic Matters
Warming four times faster than the global average, the Arctic is poorly measured. Year-round data are vital for understanding ocean circulation, climate, and marine life.

 

A Silent Colleague Beneath the Ice
Drifting with currents, the float gathers open-access data for years, listening to the ocean’s changing heartbeat long after ships can no longer sail.
