‘Seagliders’, or underwater robots, are being deployed in the North Atlantic off the west coast of Scotland by scientists who are researching climate change

Pioneering research using underwater robots suggests that remote Scottish waters could hold the key to forecasting global warming.

Unique data recorded by remotely programmable “seagliders” hundreds of miles off the west of Scotland has identified two ocean currents around the tiny, jagged outpost of Rockall that scientists think play a significant role in driving climate change.

The currents, which researchers have named the Rockall Bank Jet and Hatton Bank Jet, are thought to act like an engine, powering a complex process that has been dubbed a global conveyor belt. It carries the sun’s heat between the equator and the frozen poles in a continuous cycle, influencing weather and climate. Water in the North Atlantic takes much longer than the air to heat and cool, so…
