Short summary
Mesoscale eddies are rotating ocean features that play a key role in transporting heat, salt, and biological material. This study presents a new global dataset derived from satellite observations to track these eddies and identify when they merge or split. By organizing them into interaction networks, we show that such events are frequent and strongly influence eddy evolution, leading to a more realistic description of ocean circulation.
