Detecting a strange circle in the middle of the ocean on Google Earth, sparking controversy about “UFO”

Scott Waring, the owner of a website dedicated to posting “evidence” of aliens, recently shared a photo showing a circle in the middle of the sea on Google Earth, sparking the “UFO” controversy. “.

This strange circle lies off the coast near Peru’s Nazca line, a series of giant drawings created by the Nazca people nearly 2,000 years ago. Waring estimated the circle he found was about 6.8 km in diameter, visible about 566 km off the coast of Lima. The circle seemed to rise out of the seabed like a mountain.

However, bad news for UFO fans, this circle is just a block of Google data. Strange shapes like these can appear in certain areas of the ocean on Google Earth, which uses data from multiple sources to map the sea. These sources have different resolutions or levels of detail, and when they are stitched together, odd shapes sometimes appear at the junction point.

In a 2016 blog post, Google developers confirmed a few data conflicts that can lead to strange hill and valley-like images on the map.

For example, ocean mapping is based on a map made by the Scripps Institute of Oceanography, which uses gravity measurements from satellites to create a rough map of seafloor rise and fall, representing ocean depths. .

For more detailed mapping, the company draws data from onboard sonar, a technique that uses sound propagation to navigate, communicate or detect objects on the surface, in the water or under the water, then record the echo to get a high-resolution image. Sometimes satellite-based and onboard measurements don’t match and can result in what looks like a hill or depression.

Notably, the “UFO” detected by Waring is located right in the middle of the cross-section where the sonar survey from the ship is clearly seen, possibly this shape is a side effect of stitching together multiple data sources. These long lines are visible across the ocean on Google Earth and are sometimes mistaken for a sign of a lost civilization.

To this day, much of the ocean remains a mystery to humans. According to the US Oceanic and Atmospheric Administration, only 5% of the ocean has been mapped by modern sonar technology.
