Bruce Charles Heezen (1924-1977) was an American oceanographer and geologist who led the Columbia University team that mapped the Mid-Atlantic Ridge in the 1940’s and ‘50’s. They also discovered and named some seamounts and confirmed that there was evidence that at least the summits had been above water and existed as islands sometime during the past 12,000 years. Presumably, this was the result of the lower ocean levels during the last Ice Age.
Supporters of the theory of Atlantis being located in the Atlantic believe that the discoveries of Heezen, Maurice Ewing and others support their contention. R. Cedric Leonard(a) and Carl Martin(b) are enthusiastic members of this school of thought.
It was Heezen, along with his colleague, Dragoslav Ninkovich, who provided the first firm evidence that the Late Bronze Age eruption of Thera, directly affected the eastern part of Crete through ash fall-out in a 1965 paper.
