Ocean X team's sidescan sonar image is real and shows a round feature with a long track behind it. Divers reported a circular formation and right-angle structures and recovered samples of limonite and goethite, common in glacial till. Stockholm University geologists stated the samples are consistent with rocks dumped by retreating ice. No metal, no technology, no artifacts were recovered.
The team's own statements fed the legend: equipment failures near the site, a staircase-like structure, and speculation about a sunken UFO or Atlantis ruin, amplified by the fact that Ocean X is a commercial venture selling publicity for wreck exploration.
The structural lesson: sidescan sonar renders texture, not shape, and at this resolution a circle is a suggestion. The anomaly is a clean demonstration of how low-resolution data plus a motivated narrator manufactures a monument, the same engine as the Face on Mars, but underwater.
When a blurry circle appears on sonar, why does the answer arrive before the dive?
