Scientists exploring a submerged mountain range in the Mid-Atlantic stumbled onto something they can’t explain: An organized series of holes punched in the floor of the Atlantic Ocean.
The discovery was made Saturday, July 23, and photos show the dots connect into nearly straight lines … or trails … or designs.
NOAA Ocean Exploration isn’t yet sure how to explain it.
“We observed several of these sublinear sets of holes in the sediment. These holes have been previously reported from the region, but their origin remains a mystery,” NOAA Ocean Exploration reported.
“While they look almost human made, the little piles of sediment around the holes make them seem like they were excavated by … something.”
The July 23 dive reached depths of 1.7 miles while visiting the summit of an underwater volcano north of the Azores. A remotely operated camera was used to safely record the discoveries.
NOAA posted photos that show the holes were found in what is otherwise a flat sandy surface.
