Scientists studying a submerged mountain range in the mid-Atlantic have stumbled upon an unexplained phenomenon: a series of
“We have observed several of these sublinear setsholes in the sediment. These holes have previously been reported from the region, but their origin remains a mystery, NOAA Ocean Exploration said. “Although they appear almost man-made, the small piles of sediment around the holes give the impression that they were dug by... someone.”
The holes were discovered during a dive tothe top of an underwater volcano north of the Azores on July 23 to a depth of 2.7 km. A remote-controlled camera was used to safely record the trails.
NOAA published the photos online,which shows that the holes were found on a flat sandy surface. Scientists invited the public to express their theories about the origin of the holes.
The discovery was made as part of the expedition “Journeyto the ridge - 2022.” Its members explore and map little-studied deep-sea regions of the Charlie-Gibbs Fracture Zone, the Mid-Atlantic Ridge, and the Azores Plateau.
The Mid-Atlantic Ridge extendsat 16 000 km from north to south and is considered the longest mountain range in the world and one of the most prominent geological features on Earth.
