First evidence of city-sized icebergs found off UK coast

Icebergs as large as cities, potentially tens of kilometres wide, once roved the coasts of the UK, according to scientists.
Researchers found distinctive scratch marks left by the drifting icebergs as they gouged deep tracks into the North Sea floor more than 18,000 years ago.
It’s the first hard evidence that the ice sheet formerly covering Britain and Ireland produced such large bergs.
The findings could provide vital clues in understanding how climate change is affecting Antarctica today.
The scientists searched for fingerprints of giant icebergs using very detailed 3D seismic data, collected by oil and gas companies or wind turbine projects doing ocean surveys.
