While exploring the summit of an underwater volcano north of the Azores – near the Mid-Atlantic Ridge – scientists examined the ocean flooring at a depth of roughly 3 km.
During the Voyage to the Ridge 2022 mission, which entails investigating and charting the poorly recognized deepwater areas, the invention was made.
According to the NOAA, researchers are unable to definitively determine the origin or technique of development of the holes.
However, scientists have proposed that the holes might characterize digging and elimination by an organism residing within the sediment or, probably, by a feeding appendage of big animals on the silt high.
The Federal group stated, “The final origin of the holes nonetheless stays a thriller.”
