Pierre Termier (1859-1930) was a French geologist who analysed basaltic lava dredged up from the Atlantic seafloor 500 miles north of the Azores in 1898. Termier was confused when he found that the sample was vitreous rather than crystalline. This had to mean that the water had been submerged after cooling. Since lava disintegrates after 15,000 years Termier was forced to conclude that there had been volcanic activity above sea level in the relatively recent past, perhaps coinciding with the destruction of Atlantis.

In 1912 Termier delivered a lecture^[574] to the Institut Océanographique^(b) in which he outlined his belief that Atlantis had been located in the Atlantic, a machine translation in English is available here as Archive 3667. A brief 9-page article by Termier, entitled New Light on the Lost Atlantis, has been reprinted by Kessinger Publishing. Termier also addressed the Smithsonian Institute who published his text in their 1915 annual.

In January 1917 a firm rebuttal of Termier’s ideas was written by Charles Schuchert of Yale University and published in Geographical Review,*however, the journal also published a favourable review by Rudolph Schuller in the same edition^(a).*

In 1924 Termier he published La Derive des Continents, a paper in which he rejected Wegener’s theory of ‘Continental Drift’ as fanciful.

Although Termier’s claims are still quoted by some as factual, their scientific basis has been gravely undermined long ago, further weakening the case for Atlantis in the Atlantic.
