Doggerland: How did the Atlantis of the North Sea sink?
For a long time, scientists believed that a powerful tsunami destroyed Doggerland 8,200 years ago. Sediment analysis now suggests that the land once connecting Great Britain with the rest of Europe had a later demise.
Latest research indicates that Doggerland did not completely vanish in one tsunami
Around 10,000 years ago, at the end of the last ice age, the sea level in northern Europe was still about 60 meters (197 feet) below what it is today. The British Isles and the European mainland formed a continuous landmass.
Relatively large rivers crossed this landmass, but in a different way than we know today. The Elbe, for example, flowed into a large inland lake. The Rhine flowed from east to west over long distances. Before it reached the sea at the latitude of Brittany, the Thames flowed into it.
