Tegnene er simpelthen den rute skibet har taget med sis sonar, hvilket dokumenteres via en række billeder og udtalelser fra eksperter.
Til gengæld vil Google da ikke afvise at man finder Atlantis på havbunden - hvis Atlantis da ikke bare er andet end end et gammelt sagn.
So what is it? The scientific explanation is a bit less exotic, but we think it's still pretty interesting: these marks are what we call "ship tracks." You see, it's actually quite hard to measure the depth of the ocean. Sunlight, lasers, and other electromagnetic radiation can travel less than 100 feet below the surface, yet the typical depth in the ocean is more than two and a half miles. Sound waves are more effective. By measuring the time it takes for sound to travel from a ship to the sea floor and back, you can get an idea of how far away the sea floor is. Since this process — known as echosounding — only maps a strip of the sea floor under the ship, the maps it produces often show the path the ship took, hence the "ship tracks." In this case, the soundings produced by a ship are also about 1% deeper than the data we have in surrounding areas — likely an error — making the tracks stand out more.
