Scientists observe 'double whirlpools' in ocean for 1st time
For the first time, scientists have recorded two connected ocean whirlpools, called eddies, spiralling in opposite directions off the Australian coast. Resembling "smoke rings" in satellite observations, "ocean eddies almost always head to the west, but by pairing up they can move to the east and travel ten times as fast as a normal eddy," said lead researcher Chris Hughes.
