The seabed under the Celtic Sea is called the Celtic Shelf, part of the continental shelf of Europe. The northeast portion has a depth of between 90m and 100m, increasing towards Saint George's Channel. In the opposite direction, sand ridges pointing southwest have a similar height, separated by troughs approximately 50m deeper. These ridges were formed by tidal effects when the sea level was lower.
The Celtic Sea is the area of the Atlantic Ocean off the south coast of Ireland bounded to the east by Saint George's Channel, the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, Devon, and Brittany. The southern and western boundaries are delimited by the continental shelf, which drops away sharply.
On December 29, 1997, the BBC reported that a team of Russian scientists from the Moscow Institute of Meta-History believed they have found Atlantis in the ocean 100 miles off Land's End, England. The BBC stated that Little Sole Bank, a relatively shallow area on the edge of the Celtic Shelf, was believed by the team to be the capital of Atlantis. The same Institute sent a parallel team to Bolivia to look for Atlantis there.
The idea of Atlantis off of Land's End may have been based on the myth of Lyonesse, which was a country in Arthurian legend. Said to border Cornwall, it was most notable as the home of the hero Tristan, whose father was king. In later traditions Lyonesse is said to have sunk beneath the waves some time after the Tristan stories take place, making it similar to Ys and other lost lands in medieval Celtic tales and perhaps connecting it with the Isles of Scilly.

From a press release:
The Institute of Metahistory was founded in February 1997, and is an autonomous non-profit organization (Russian Federation State Registration #639026).
The Institute of Metahistory unites people who believe that the existing ideas of the past of the human civilization can be wrong in many respects, since they were evolved on the basis of data which can hardly be considered exhaustive, and bear the imprint of a vast number of stereotypes.
We think that as a result of closer cooperation between different sciences, the renunciation of biased opinions and the arrogant confidence that modern science, at least basically, knows everything about everything, a fuller and more reliable picture of the past of the human civilization could be reconstructed.
We are aware that all the suggestions must be substantiated and verified, and all the assertions - proved. And this we will do.
The supreme managing body of the Institute of Metahistory, taking decisions on all the key issues, is its Collegium, which is composed of:
Alexander BYALKO, D.Sc. (Physics and Mathematics), Member of the Board of the International Association of "What? Where? When?" Clubs;
Georgios PANAGOPOULOS, film and theatre director;
Viatcheslav KOUDRIAVTSEV, Member of the Russian Geographical Society of the Russian Academy of Sciences - Director of the Institute of Metahistory.
The Board of Trustees of the Institute of Metahistory renders assistance in the realization of the projects of the Institute of Metahistory and supervises its activities from the viewpoint of their conformity to the objectives and aims of the Institute and the legislation in force. The Board of Trustees has not been completely formed, as of today it includes:
Alexander GORODNITSKY, Professor, D.Sc. (Geology and Mineralogy), Full Member of the Russian Academy of Natural Sciences, Head of Laboratory at the Shirshov Oceanology Institute of the Russian Academy of Sciences, Member of Writers' Union, President of the Association of Russia's Bards.
