When a grid-like pattern first appeared on Google Ocean in 2009, believers were quick to hail this as the lost city of Atlantis. A strange grid-like undersea structure was seen on the cartographic application, off the coast of West Africa, about 600 miles west of the Canary Islands. Incidentally, this is close to the supposed location, at which the fabled island had originally sunk. Google had denied it back then, stating that the lines represented sonar data collected from boats.
According to the writings of the Greek philosopher Plato, Atlantis was supposed to be a real island. His accounts from 360 BC mention that the island was home to a civilisation more scientifically advanced than anywhere else on the planet at the time. In fact, they even had flying machines. The island is said to have met a disastrous end in around 9000 BC, when it suddenly sunk in a single day along with its entire civilisation, after its residents failed to conquer Athens.
As it was explained, Google Ocean, an extension of Google Earth, was displaying a data artefact, which was a result of the sonar measuring methods used by ships to chart the terrain of the seafloor. The grid structure is due to the pattern in which these ships crisscrossed across the ocean during this charting operation. After a 3-year long delay, Google finally updated the application with new data correcting this anomaly. The new seafloor now conforms to data from the Scripps Institution of Oceanography and other authoritative groups. Having said that, a closer look reveals that the grid is still visible, although it is a lot less pronounced than before.
