Doggerland

Doggerland was an area of land in Northern Europe, now submerged beneath the North Sea, that connected Britain to continental Europe. It was flooded by rising sea levels around 6500–6200 BCE. The flooded land is known as the Dogger Littoral. Geological surveys have suggested that it stretched from what is now the east coast of Great Britain to what is now the Netherlands, the western coast of Germany and the Danish peninsula of Jutland. It was probably a rich habitat with human habitation in the Mesolithic period, although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide. Doggerland was named after the Dogger Bank, which in turn was named after 17th-century Dutch fishing boats called doggers. The archaeological potential of the area was first identified in the early 20th century, and interest intensified in 1931 when a fishing trawler operating east of the Wash dragged up a barbed antler point that was subsequently dated to a time when the area was tundra. Vessels have since dragged up remains of mammoths, lions and other animals, and a few prehistoric tools and weapons. international teams are continuing a two-year investigation into the submerged landscape of Doggerland using new and traditional archaeo-geophysical techniques, computer simulation, and molecular biology. Evidence gathered allows study of past environments, ecological change, and human transition from hunter-gatherer to farming communities. Until the middle Pleistocene, Great Britain was a peninsula of Europe, connected by the massive chalk Weald–Artois Anticline across the Strait of Dover. During the Anglian glaciation, about 450,000 years ago, an ice sheet filled much of the North Sea, with a large proglacial lake in the southern part fed by the Rhine, the Scheldt and the Thames. The catastrophic overflow of this lake carved a channel through the anticline, leading to the formation of the Channel River, which carried the combined waters of the Rhine, the Scheldt and the Thames to the Atlantic.
