Giant, flat-topped icebergs the size of the city of Cambridge drifted off the coast of Britain during the last ice age, according to a study that has uncovered evidence of their existence for the first time.
A series of distinctive, comb-like grooves found preserved in sediment near Aberdeen in Scotland were left behind by the underside of huge “tabular” icebergs that dragged across the North Sea floor between 18,000 and 20,000 years ago, the researchers said.
