Storegga submarine slides are enormous underwater movements of glacial sedimentary deposits that were only recently identified. While many of these occurred following the melting of the glaciers at the end of the last Ice Age some more recent movements have also been identified. Either earthquakes or the decomposition of gas hydrates are their most likely cause. As many as three storegga have been identified that occurred off the west coast of Norway around 6000-5000 BC(a). The combined volume of material involved in the last two events has been calculated at 1700 cubic kilometres. As a consequence, gigantic tsunami were generated which flooded a number of landmasses including Scotland. Ulf Erlingsson suggests that one of these events, around 6100 BC, may have been responsible for the final submergence of the Dogger Bank in the North Sea, creating the impassable muddy shoals mentioned by Plato.
The dating of these events is discussed by Bernhard Weninger and his associates in a 2008 paper available online(b).
Knut Rydgren and Stein Bondevik of Norway’s Sogn og Fjordane University have concluded that the flooding of Doggerland as a result of the Storegga event took place at the end of autumn(g).
The evidence to-date suggests that the flooding of the Black Sea coincided with a storegga event, which would require a catastrophe on a scale not previously considered. In a 2017 paper(e), John M. Jensen offers additional evidence to support this contention.
In 2014, Dr. Jon Hill revealed(d) the results of a study of the impact of the 6,200 BC Storegga on the low-lying Doggerland stating that “We were the first ever group to model the Storegga tsunami with Doggerland in place. Previous studies have used the modern bathymetry (ocean depth).” The study was commented on further by Axel Bojanowski in Der Spiegel with an English translation on the de Grazia website(f). The scale of the landslide is graphically described there.
In 2015 the UK’s Daily Mail offered further details(c) gleaned from articles in the respected journal Geology and Science Nordic.
Dr. Ulf Erlingsson is a Swedish geographer, geomorphologist and an expert in underwater mapping. In order to explain several puzzles regarding the Ice Age he developed The Captured Ice Shelf Hypothesis. He was the chairman of the Geographic Society of Uppsala, Sweden and 1991 he received the Linnaeus Prize from the Royal Society of Sciences in Uppsala.
Erlingsson is currently the American representative of AB Hydro consult(a), a spin-off from Uppsala University, Department of Physical Geography.
During the 1990’s while studying the geography of the Baltic region, Erlingsson obtained a set of Soviet maps, which greatly assisted the building of the database he was engaged in. However, these maps, which had been bought openly in Riga, outlined plans for a Russian invasion of Sweden in the event of a war in Europe with NATO(b).
Since moving to Florida, Erlingsson has been very involved politically with the ‘Progressive’ wing of the Democratic Party.
Erlingsson recently identified the empire of Atlantis with the megalithic cultures of Western Europe and North Africa and suggested its capital may have been located in Ireland. His book is interesting and contains a number of original ideas. However, as an Irishman, I am not convinced that our remarkable monuments in the Boyne Valley are the remains of or related to Atlantis. I will discuss this further in my review of his book. Erlingsson sees Atlantis everywhere, for example, in a carving on a stone basin in the Knowth passage tomb close to Newgrange.
Erlingsson has also suggested that the Irish authorities have deliberately made Newgrange inaccessible. This is total nonsense. As a regular visitor to the site over the years, I have witnessed nothing but every effort being made to maximise the throughput of visitors into the very confined space within our most famous national monument. The carved basin (see image) discovered near Newgrange, is perceived by Erlingsson as a replica of Plato’s circular city of Atlantis while I can see an early version of a Babylonian winged disk. In 2005, probably as a promotional ploy, he issued a challenge for an open debate on his theory.
Frank Joseph has related speculative ideas claiming that “the early date for New Grange, its circular construction, sophisticated solar orientation and mythic tradition all point to Atlantean origins.”[0636.70]
Erlingsson has more recently suggested that the ‘sunken’ island referred to by Plato was probably located in the vicinity of the southern end of the North Sea. He proposes that around 6100 BC a tsunami generated by a massive storegga off Norway reduced the then low-lying Dogger Bank to the impassable muddy shoals recorded by Plato!*He has suggested that the original Atlantis narrative, conveyed to Solon, was a mixture of an account of megalithic Ireland and a report of the inundation of Doggerland.*
Dr. Patrick Wallace, the Director of the National Museum of Ireland, declared that he was unaware of any archaeological evidence to support Erlingsson’s claims.
Nevertheless, Erlingsson has produced some interesting material on the bursting of glacial lakes or what are known in Iceland as jökulhlaups and their possible effect on the ending of the last Ice Age(c).
