Atlantis Found?

Probably not Atlantis, as I feel that Atlantis was found on the island of Santorini just off the costs of Greece and Italy. However, this find on the floor of the Atlantic Ocean is still very interesting in it's own right. This image was seen on the NOAA / NAVY surveys of the ocean floor - the ones used to general Google Earth photos. However, it is also seen on other maps of the ocean floor from various other agencies at various other times and to various other scales.

As can bearly be seen in the image above there are what appear to be city streets on the floor of the ocean. The image is at 31.404883221 degrees N by -24.41347612 degrees W, and at an altitude of 5,461 meters below sealevel.

The official explanation is that they are "echos" from the sonar used to map the floor - well, yes, as that is what all the lines are - because THAT IS HOW SONAR works! But even if it was some sort of interference, it would not occur in various other sources. It could just be a very interesting natural occurance on the floor of the ocean, but it would be nice to find out.
