The first Brexit: Submerged landscapes of the North Sea and Channel

The British Isles split from Europe several thousand years ago. Now, maritime archaeology is revealing a lost landscape on the seafloor

The British Isles separated from the European continent approximately 8,000 years ago. For this Brexit there was no referendum or bus, no Leavers or Remainers, nor was it hard or soft. This was a watery Brexit as rising sea levels filled the Channel and created the North Sea. Maritime archaeology is revealing this submerged landscape that once connected the continent to Britain.

Earth is a dynamic planet that is constantly changing. Going back far enough in time, Britain has been separated from the continent several times as sea levels changed. However, for the study of Homo sapiens it is the change at end of the Pleistocene and the start of the Holocene epoch 11,700 years ago that is most interesting.
