Atlantis...?

Let's talk about non-computer stuff for once... I don't know if you read about the Danton (a French military boat sunk during the first world war by a German submarine) discovery last week... Quite interesting. A friend of mine sent me a link to this article about the possible discovery of the Atlantis today. It's in French, but the idea is this: there is a strange sign of submarine structure more or less where Plato had determined the Atlantis would have been located before its destruction. Although apparently scientifics say it is an artefact due to variable sources for the map generation data, I cannot help but wonder... why would that area be specifically be better analysed than others? Apparently, the area is more than 100km on each side... See it in Google Maps
