Professor Hans Pettersson (1888-1966), was a renowned Swedish scientist, who became the first full professor of oceanography in Sweden and in 1938 founded the Institute of Oceanography in Gothenburg.
Thorwald C. Franke has written a short paper(b) on Pettersson’s important contribution to the Atlantis debates, offering scientific reasons for dismissing the idea of Atlantis being located in the Atlantic. In the process he refuted the earlier theories of Pierre Termier and demolished the idea of transatlantic land bridges.
Although he has excluded the Atlantic, he is equally unhappy with a Mediterranean location, preferring not to accept the Atlantis story as history!
He published his views, in Swedish, in 1944 as Atlantis och Atlanten, which was subsequently translated into German by another physicist, Stefan Meyer, entitled Atlantis und Atlantik.
>An article on the Atlantisforschung website by Ferdinand Speidel offers a totally different view of Petterson’s Atlantis ‘scepticism’(c).<
Pettersson led the Swedish Albatross Expedition of 1947-1948 which surveyed the Atlantic. He subsequently spoke of finding evidence of “great catastrophes that have altered the face of the Earth”(a)

Herbert Edward Forrest was a Welsh naturalist, who endeavoured to convince his readers that a landbridge had existed across the North Atlantic within the memory of humans and that it had been the location of Atlantis. His book includes a speculative map showing Atlantis at the time of the last Ice Age.
Others, in the early part of the 20th century, supported this suggestion; such as Dr. R. F. Scharff although the idea was strongly opposed by the likes of William Diller Matthew(1871-1930), professor of palaeontology at the University of California(a). Eventually, this ill-founded idea of an Atlantic landbridge during the Holocene Era sank from view and has no serious support today.
>However, an interesting review of Forrest’s book was published in 2015 by Ferdinand Speidel on the Atlantisforschung website in German. I have added a Google Translation below(b).<
