We must learn to both sustainably exploit and protect our vast oceans, provider of oxygen, food, hydrocarbons and other resources. A solution lies in sensing and interacting through an Internet of Things, with distributed networks of intelligent sensors and actuators. Unfortunately, we currently lack a marine Internet, crucial to achieve distributed, coordinated and adaptive control, due to the rapid absorption of light and radio waves in seawater.

Underwater robots can explore seas and rivers, gathering in groups to solve problems together, if they learn to cooperate.
