"To solve the age-old mystery, the team used a satellite photo of a suspected submerged city to find the site just north of Cadiz, Spain. There, buried in the vast marshlands of the Dona Ana Park, they believe that they pinpointed the ancient, multi-ringed dominion known as Atlantis.
The team of archeologists and geologists in 2009 and 2010 used a combination of deep-ground radar, digital mapping, and underwater technology to survey the site."
This is an interesting find, no doubt, but the Atlantis spin was apparently added to jazz up the discovery, which will be described in an upcoming National Geographic Channel special called "Finding Atlantis."
