Sinking Atlantis, again

kw: legends, myths, lost worlds

Remember this image? Similar images, purported to be Atlantis, are everywhere now. I posted about it a few days ago, asking, If it isn't Atlantis, what is it? My own speculation is that it is the trace of a seismic or sonar survey, or perhaps trawling. That is the position taken by most commentators. The Bits Blog at the N.Y. Times reports on Google's debunking of the Atlantis idea.

Two things come to mind, however. There are many sonar and seismic surveys done, often over equally large areas. The ocean floor ought to be marked up like the wall of a house inhabited by artistic toddlers. I've done some looking around, and so far I haven't found anything similar.

But it is hard to get an idea of the scale of this thing. It is 120x120 km, or 75x75 miles. I clipped an image of the Los Angeles area at the same scale for comparison.

It takes a couple hours, or more if there is traffic, to drive from Oxnard to Oceanside or San Bernardino. A 120x120 km square takes in from Lancaster to Irvine and Santa Monica to Riverside. That's a lot of territory. Though the "Atlantis" image looks like a city laid out in blocks, the blocks are big. Each one is about the size of Anaheim or Pasadena.

It's worth while looking for more traces on the ocean floor. I don't know why this one formation off Africa should be unique. I am pretty sure the formation was caused by something towed behind (and below) a ship.
