Sonar images interpreted as being symmetrical and geometric stone structures resembling an urban complex were first recorded in early 2001 covering an area of 2 square kilometres (200 ha)[
remotely operated vehicle that filmed sonar images interpreted as various pyramids and circular structures made out of massive, smooth blocks of stone that resembled hewn granite. Zalitzki said, "It's a really wonderful structure which really looks like it could have been a large urban centre. However, it would be totally irresponsible to say what it was before we have evidence."[1]
After studying the images,
National Geographic senior editor John Echave said: "They are interesting anomalies, but that's as much as anyone can say right now, but I'm no expert on sonar and until we are able to actually go down there and see, it will be difficult to characterize them."[5] Professor of oceanography Robert Ballard was quoted as saying: "That's too deep. I'd be surprised if it was human. You have to ask yourself: how did it get there? I've looked at a lot of sonar images in my life, and it can be sort of like looking at an ink blot -- people can sometimes see what they want to see. I'll just wait for a bit more data."[5]
Marine geologist
Manuel Iturralde called for more samples before drawing conclusions about the site, saying the results so far were very unusual. He estimated that it would have taken 50,000 years for such structures to have sunken to the depth at which they were said to be found and stated that none of the known cultures living that long ago had the ability to build such structures. A specialist in underwater archaeology at Florida State University added: "It would be cool if they were right, but it would be real advanced for anything we would see in the New World for that time frame. The structures are out of time and out of place."[4]
