Deep within the waters a volcanic ridge within the bottom of the Atlantic Ocean, ocean explorers used a remotely operated vehicle to look at unknown areas where they found a pattern of holes within the sand.

HIGHLIGHTS
Ocean explorers found holes in the unknown areas of the bottom of the Atlantic Ocean
Four more sightings found on the Azores Plateau, where three tectonic plates meet
Scientists spotted similar holes nearly two decades ago

During the dive, north of the Azores which would be near Portugal’s mainland, on July 23 they had seen a dozen sets of holes resembling a track of lines on the ocean bed, at a depth of 1.6 miles.

On Thursday, after a week later, there have been four additional sightings on the Azores Plateau which would found underwater terrain where the three tectonic plates would eventually meet. Well, those holes were about a mile deep and about 300 miles away from the site of the expedition's initial discovery. 

The scientists scientists do not have any clue about the holes but they had similar markings before and would consider them to be “lebensspuren,” German for “life traces,” which would refer to impressions in sediments that would be the work of living organisms.

As per Emily Crum, the NOAA spokesperson around two decades ago, about 27 miles far from the location of the present expedition’s initial sighting, scientists had noticed similar holes during an exploration. 

But the passage of time had not provided any clear answers, as mentioned by Micheal Vecchione, a NOAA deep-sea biologist who participated in that project and was found to be a part of this latest expedition.

Dr. Vecchione has described that “there are somethings necessary happening there and we don't even know what is it exactly.” He added 'this would highlight the fact that there were still mysteries out there.”

However, one of all the queries that scientists on an ambitious ocean expedition are inquiring, as they would explore the Mid-Atlantic Ridge which would be considered as a section of a huge deep-ocean range of mountains and stretches for over 10,000 miles below the Atlantic Ocean.

In a paper which provides an information about the holes noticed in 2004, Mr. Vecchione and his co-author, Odd Aksel Bergstad, a former research worker at the Institute of Marine Research in Norway had pointed out two main hypotheses for the reason of the holes that exists. In both the cases, it involved marine life, either by walking or swimming on top of the sediment and poking holes down, or the inverse scenario which would be burrowing within the sediment and jabbbing holes up.

As per Dr. Vecchione, the holes seen on Thursday seemed to have been pushed out from underneath.
