Scientists exploring a submerged mountain range in the middle of the Atlantic have come across something they can’t explain: an organized series of holes drilled into the floor of the Atlantic Ocean.
The discovery was made on July 23, and photos show the dots connecting in nearly straight lines…or streaks…or patterns.
NOAA Ocean Exploration does not yet know how to explain it.
“We have observed several of these sublinear sets of holes in the sediment. These holes have been previously reported in the region, but their origin remains a mystery,” reported NOAA Ocean Exploration.
“Although they look almost man-made, the little piles of sediment around the holes make them look like they’ve been dug out by… something.”
The July 23 dive reached depths of 1.7 miles while visiting the top of an underwater volcano north of the Azores. A remote-controlled camera was used to securely record the finds.
NOAA released photos that show the holes were found in what is otherwise a flat sandy surface.
Scientists invited the public to offer theories, but commenters raised more questions, including some who questioned whether the holes were made by someone taking core samples.
“Is it an object or an animal inside the holes?” Does this line go in the same direction as the current? Asked Anthony Narehood.
“Water from underground springs?” Mike Weathersby posted.
“What about methane gas?” says Eduardo Pogorelsky.
The discovery was made as part of the Voyage to the Ridge 2022 expedition, which is exploring and mapping the “poorly understood deep water areas of the Charlie-Gibbs Fracture Zone, the Mid-Atlantic Ridge and the Upper Azores”.
The Mid-Atlantic Ridge stretches 10,000 miles from north to south and is considered “the world’s longest mountain range and one of Earth’s most significant geological features,” says NOAA Ocean Exploration.
“The majority lies underwater and therefore much of it remains largely unexplored. With active tectonic spread, MAR is the site of frequent earthquakes,” reports NOAA.
“Hydrothermal vents can form where magma provides heat as it rises toward the seafloor. These vents are known to support diverse chemosynthetic communities. away from the fault zone.”
