During an investigation by scientists of the NOAA Ocean Exploration, they found a mysterious line of holes at the summit of an underwater volcano north of the Azores at a depth of 1.7 miles in the Atlantic Ocean.

An organized network of holes drilled into the ocean floor was discovered by scientists investigating a submerged mountain range in the middle of the Atlantic.
Photos taken after the discovery on July 23 show how the dots connect to form nearly straight trails, designs, or lines.
NOAA Ocean Exploration is still unsure about 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 dive on July 23 to the summit of an underwater volcano north of the Azores at a depth of 1.7 miles. The discoveries were carefully captured with a remotely operated camera.
Photos from NOAA reveal that the holes were found on a flat, sandy surface.
The public was required to submit theories, but in the comments, people asked more pointed questions, such as whether the holes were caused by someone taking core samples.
“Is that an object or animal inside the holes? Does that line run in the same direction as the current?” Anthony Narehood asked.
“Water from underground springs?” Mike Weathersby posted.
“What about gas methane?” Eduardo Pogorelsky said.
The Charlie-Gibbs Fracture Zone, Mid-Atlantic Ridge, and Azores Plateau are three poorly understood deepwater areas that are being explored and mapped by the Voyage to the Ridge 2022 voyage.
According to NOAA Ocean Exploration, the Mid-Atlantic Ridge, which spans 10,000 miles from north to south, is “the longest mountain range in the world and one of the most prominent geological features on Earth.”
“The majority of it sits underwater and thus much of it remains largely unexplored. With active tectonic spreading, the MAR is the site of frequent earthquakes,” NOAA reports.
“Hydrothermal vents may form where magma provides heat as it rises to the seafloor. These vents are known to support diverse chemosynthetic communities. However, little is known about life at these sites once vents go extinct, or what life lies beyond the vents, further away from the rift zone.”
