In March, a team of scientists dragged a blast furnace on a sled across a giant slab of ice in the Beaufort Sea, above the Arctic Circle. With the furnace, the researchers (from the United States Navy and the Massachusetts Institute of Technology) melted a hole in the ice big enough to fit their 850-pound, 12-foot drone, which they dropped through to the icy waters below. Their mission: to measure how climate change is altering the acoustics of the Arctic Ocean.

Swarms of pumpkin-like robots could explore and map the oceans

A start-up is developing underwater drones to map the seas.

THE planet’s surface is more than 70 per cent water. Yet we know more about the moon than we do about what’s going on in the deep oceans. A Massachusetts start-up has a ball-sized robot it wants to fix that.

Meet EVE – the Ellipsoidal Vehicle for Exploration – a sensor-studded yellow robot the shape of a pumpkin.
