You probably know that 70% of the Earth is covered with oceans but only 5% of it is  actually explored. But have you heard about the weird sounds made by unknown huge objects or oceanic creatures? What about a huge submerged rock structure in Japan? 

In this article, we’ve handpicked the most breathtaking legends and uncharted mysteries from the oceans’ depths so you can learn a bit more about these enigmatic phenomena. All aboard! 

The Glowing Secret of the Milky Sea 

An amazing milky glow of the ocean is a beautiful but still unexplained phenomenon. According to one of the versions, the milky sea is caused by the activity of bioluminescent bacteria that produce light in response to threats or attract a mate. As a result, the water of the oceans is glowing blue which looks milky white at night. 

The sailors from the 19th century had no clue about the possible reasons for this phenomenon so it was really shocking and horrifying for them. Some sailors were sure that the milky sea is the creation of ancient ocean creatures like sea serpents or sirens.

However, the milky sea is so bright that it can be seen from outer space and it casts doubt on the theory about bacteria activity. Nevertheless, whatever the source of this breathtaking glow, it’s definitely worth seeing with your own eyes!

The Phenomenon of a Green Flash 

The green flash is a beautiful phenomenon that can be seen for just a few seconds at sunrise and sunset. It’s actually an optical illusion as the atmosphere diffracts the light and breaks it into various colors but not all of them can reach our sight. As a result, the sun becomes green for a moment. The first photo of the green flash was made in 1960 by D.K.J. O’Connell, an astronomer and a seismologist from England.

To catch the green flash, you will require a cloudless day and a clear horizon, so sandy ocean beaches are perfect for this purpose. You can see it at sunset or sunrise when the upper edge of the sun is barely visible. The sun will turn green for just a few seconds — this view is extremely impressive!

Moreover, it’s believed that the green flash brings good luck to those who catch it, so give it a shot! 

The Mysterious Object in the Baltic Sea

In 2011, a group of divers found a strange circular object in the Baltic Sea at a depth of 300 feet. The shape of this entity is round and the circumference is about 60 feet. The origins of this object are still unknown and thanks to its shape, some folks even claim it was an alien spaceship. 

When the mysterious object was unearthed, the researchers came to the conclusion that it could land in the Baltic Sea during World War II. The war experts suggest that it might have been a ballistic tool from Germany. 

The second version seems more realistic than the one about the spaceship, but the whole truth about this ocean mystery is still to be discovered.

Strange Sounds From the Ocean

In 1999, the National Oceanic and Atmospheric Administration managed to record a strange sound from the Pacific Ocean. The sound came from near the equator by South America and lasted almost 3 minutes. According to one of the theories, it could be an unknown ocean creature, but researchers believe that the sound was caused by the icebergs. 

It’s just one of the many mysterious sounds recorded by hydrophones, but their sources haven’t been discovered yet. The scientists think that the sounds were caused by undersea volcanic activity and icebergs, but who knows?

Yonaguni Monument 

The world-famous underwater rock structure was discovered in 1985 by Kihachiro Aratake when he was diving near Yonaguni island in Okinawa, Japan. This huge star-like monument is made of sandstone and mudstone, it’s 165 feet long and 65 feet wide. 

According to one of the theories, this rock structure was formed naturally, but some people believe that it’s a relic from an ancient civilization. Masaaki Kimura, a professor of geology from the University of the Ryukyus estimated that the monument was created about 2000 years ago. 

This impressive monument draws a huge amount of tourists and divers and it’s not a surprise. Its mysterious history, lots of legends and theories about the origin of this rock structure make the Yonaguni Monument one of the most tempting tourist attractions.
