The flooded land is known as the Dogger Littoral.[1] Geological surveys have suggested that it stretched from what is now the east coast of Great Britain to what are now the Netherlands, the western coast of Germany and the Danish peninsula of Jutland.[2] It was probably a rich habitat with human habitation in the Mesolithic period,[3] although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a tsunami caused by the Storegga Slide.[4] Doggerland was named after the Dogger Bank, which in turn was named after 17th-century Dutch fishing boats called doggers.[5]
