Massive icebergs once roamed off coast of the UK
- Scientists discovered distinctive scratch marks left by drifting icebergs on the North Sea floor.
- These icebergs broke from the British-Irish ice sheet between 18,000 and 20,000 years ago as the climate warmed.
- Researchers used detailed 3D seismic data to locate deep comb-like grooves preserved in ocean sediments.
- The marks indicate the presence of massive tabular icebergs up to tens of kilometers wide.
- This evidence shows the UK had ice shelves and helps understand modern Antarctic ice loss.

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation
Understanding how regime shifts in iceberg calving behavior affect ice shelf stability remains a challenge for numerical models. This is an important question as we consider the fate of the ice shelves that currently buttress the Antarctic Ice Sheet and hold back the bulk of its potential upstream sea-level contribution. Using buried landforms, we demonstrate that ice shelves fringed the former British-Irish Ice Sheet (BIIS) and document their d…
Giant Icebergs off Britain: Ancient Drift Reveals
Giants of the Past: How Ancient Icebergs Could Hold the Key to Antarctica’s Future Imagine icebergs the size of cities – that’s the scale of the colossal tabular icebergs that recently emerged from the depths of the North Sea, offering a stunning glimpse into Britain’s glacial past. A new study, analyzing ancient sediment layers near Aberdeen, Scotland, has revealed compelling evidence of these behemoths, which drifted off the coast during the l…
