Doggerland

Doggerland was an area of land in Northern Europe, now submerged beneath the North Sea, that connected Britain to continental Europe. It was repeatedly exposed at various times during the Pleistocene epoch due to the lowering of sea levels during glacial periods. It was last flooded by rising sea levels around 6500–6200 BCE. 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 is 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]

Until the middle

During the most recent glaciation of the Last Glacial Maximum, the North Sea and much of the British Isles were covered with glacial ice, and the sea level was about 120 m (390 ft) lower. The climate later became warmer, and around 12,000 BCE, Great Britain, as well as much of the North Sea and the English Channel, was an expanse of low-lying tundra.^[10]

Evidence, including the contours of the present seabed, indicates that after the first main Ice Age the

One large river system found by a 3D seismic survey, undertaken by the Birmingham "North Sea Palaeolandscapes Project", drained the southeastern part of the Dogger Bank hill area into the east end of the Outer Silver Pit lake. It has been named the Shotton River after the Birmingham geologist Frederick William Shotton.

Disappearance

As ice melted at the end of the last glacial period of the current ice age, sea levels rose and the land began to tilt in an isostatic adjustment as the huge weight of ice lessened. Doggerland eventually became submerged, cutting off what was previously the British peninsula from the European mainland by around 6500 BCE.^[10][13] The Dogger Bank, an upland area of Doggerland, remained an island until at least 5000 BCE.^[10][13] Key stages are now believed to have included the gradual evolution of a large tidal bay between eastern England and Dogger Bank by 9000 BCE and a rapid sea level rise thereafter, leading to Dogger Bank becoming an island and Britain becoming physically disconnected from the continent.^[14]

A recent hypothesis suggests that around 6200 BCE much of the remaining coastal land was flooded by a tsunami caused by a submarine landslide off the coast of Norway known as the Storegga Slide. This suggests "that the Storegga Slide tsunami would have had a catastrophic impact on the contemporary coastal Mesolithic population ... Britain finally became separated from the continent and in cultural terms, the Mesolithic there goes its own way."^[14] It is estimated that up to a quarter of the Mesolithic population of Britain lost their lives.^[15] A study published in 2014 suggested that the only remaining parts of Doggerland at the time of the Storegga Slide were low-lying islands, but supported the view that the area had been abandoned at about the same time as the tsunamis.^[4]

Another view speculates that the Storegga tsunami devastated Doggerland, but then ebbed back into the sea, and that later Lake Agassiz (in North America) burst, releasing so much fresh water that sea levels rose over about two years to flood much of Doggerland and make Great Britain an island.^[16] The difference in distribution of broken shells between lower-lying and high-lying parts of the area also suggest survival of land after the Storegga tsunami.^[17]

Discovery and investigation by archaeologists

The existence of what is now known as Doggerland was established in the late 19th century. The remains of plants brought to the surface from Dogger Bank were studied in 1913 by

Interest was reinvigorated in the 1990s by Bryony Coles, who named the area "Doggerland" "after the great banks in the southern North Sea"^[11] – and produced speculative maps of the area.^[11][19] Although she recognised that the current relief of the southern North Sea seabed is not a sound guide to the topography of Doggerland,^[19] this topography has more recently begun to be reconstructed more authoritatively using seismic survey data obtained from oil exploration.

Between 2003 and 2007, a team at the University of Birmingham led by Vince Gaffney and Ken Thomson mapped around 23,000 km² (8,900 sq mi) of the Early Holocene landscape, using seismic data provided for research by Petroleum Geo-Services, as part of the work of the University of Birmingham North Sea Palaeolandscapes Project.^[20] The results of this study were published as a technical monograph and a popular book on the history and archaeology of Doggerland.^{[21][22][23][24]} Names have been given to some of its features: "The Spines" to a system of dunes above the broad "Shotton River", the upland area of the "Dogger Bank", a basin between two huge sandbanks called "The Outer Silver Pit".^[25]

In 2012 the results of study of Doggerland by the universities of Birmingham, St Andrews, Dundee, and Aberdeen, including surveys of artefacts, were displayed at the Royal Society summer exhibition in London.^[29] Richard Bates of St Andrews University said:^[29]

We have speculated for years on the lost land's existence from bones dredged by fishermen all over the North Sea, but it's only since working with oil companies in the last few years that we have been able to re-create what this lost land looked like ... We have now been able to model its flora and fauna, build up a picture of the ancient people that lived there and begin to understand some of the dramatic events that subsequently changed the land, including the sea rising and a devastating tsunami.

Since 2015 the University of Bradford's Europe's Lost Frontiers^[30] project has continued mapping the prehistoric landscapes of Doggerland and has used this data to direct a programme of extensive coring of marine palaeochannels. Sediment from the cores has provided sedimentary DNA as well as conventional environmental data and these will be used in a major computational modelling programme replicating colonisation of the submerged landscape.^[31][32]

In 2019 a team of scientists from the University of Bradford and Ghent University found a hammerstone flint on the seabed 40 km (25 mi) off the coast of Cromer, Norfolk, from a depth of 32 m (105 ft), which could point to the existence of prehistoric settlements.^[33][7]

An internationally significant early Middle Palaeolithic finds assemblage from the southern North Sea was also discovered through aggregate dredging off the coast of Norfolk. The cultural material was found to be associated with a floodplain deposit of the now submerged Palaeo-Yare river system.^[34]

Ancient artefacts have been found by beachcombers in material dredged from the sea bottom 13 km (8.1 mi) offshore and

  Time Team documentary series called "Britain's Drowned World".^[36][a]
  It was followed up in 2017 by "Britain's Stone Age Tsunami", investigating the Storegga Slide's effect on the land.
