Secrets of the ocean

Our oceans are full of secrets. Buried beneath the deep waters lie ruins of fascinating and marvelous long forgotten ancient kingdoms. Underwater explorers have also discovered mysterious objects of unknown origin, entire rivers and jungles, and even huge canyons.

Now let us remember that the ocean covers 71 percent of the Earth’s surface and contains 97 percent of the planet’s water, yet more than 95 percent of the underwater world remains unexplored. One cannot help wondering what else is hiding deep beneath the unknown waters.

We have put together a list of some of the most remarkable and interesting underwater discoveries that captured our attention.

In ancient times, the city of Thonis-Heracleion, known in modern tiles as the lost kingdom of Cleopatra served as a gateway to Egypt. Today, this mysterious legendary city is submerged in Egypt’s Aboukir Bay, near Alexandria.

Why the city sank remains a mystery, but it was swallowed by the Mediterranean Sea and has been buried in sand and mud for more than 1,200 years.

New amazing underwater discoveries allow archeologists to piece together clues and to create an image of what life was like in the ancient city.

Incredible underwater images clearly show the gap between Europe and United States is widening! To see how the tectonic plates are moving apart, one has to be prepared for some extreme diving.

This amazing underwater journey shows some of the inevitable changes on our planet.

3. Who Installed “This Object” At The Bottom Of The Ocean?

Looking at this odd construction, one has to ask – Who installed this object at the bottom of the ocean?

This construction was video-recorded by Olympic Challenger, a ROV Support Vessel on 11 September 2010.

It’s an unknown object which appears to have been installed on the ocean floor, rather than being a piece of wreckage from Deepwater Horizon.

4. Secrets Of Ancient Underwater City Pavlopetri Revealed – Travel Back In Time And See What The City Looked Like!

Once a long time ago, this unique place was inhabited by an advanced civilization. Then, something happened and the city vanished consumed by the sea.

Some say this is the world’s oldest city and the underwater ruins are remains of the legendary city of Atlantis.

The city of Pavlopetri, underwater off the coast of southern Laconia in Greece, is about 5000 years old.

This underwater site is unique.

5. Mysterious Object At The Bottom Of The Baltic Sea

During the second expedition, something very strange happened when the divers approached the mysterious object.

What exactly is it that the Ocean Explorer team has discovered at the bottom of the sea?

When the Ocean X Team returned from their first expedition, the divers knew that they had come across something strange, but no-one could determine the nature of the object and there were a number of speculations.

The mystery has been solved! Aliens are not responsible for the creation of these remarkable underwater circles discovered in the Pacific Ocean earlier this year.

The unknown creator of these advanced circular patterns is in fact a small and very intelligent fish!

The mystery circles were discovered by scuba diver Yoji Ookata who spotted something he had never encountered before.

7. Remarkable Rivers With Trees, Leaves And Waterfalls Discovered Under The Sea!

Rivers under the sea can really exist! The ocean has many secrets and underwater rivers are a big mystery.

Scientists have discovered a massive underwater river flowing along the bottom of the Black Sea. This amazing undersea river is complete with trees and leaves flowing on the sea bed, and even waterfalls!

It is estimated that if on land, the undersea river would be the world’s sixth largest in terms of the volume of water flowing through it. It is about 350 times greater than the River Thames and 10 times greater than Europe’s biggest river, the Rhine.

8. Unknown World Of Volcanic Underwater Activity At Loki’s Castle In The Arctic Ocean

At Loki’s Castle in the Arctic Ocean, researchers from the University of Bergen (UiB), Norway have discovered a so far unknown world of volcanic activity underwater.

These discoveries are incredibly interesting as they represent a part of the Norwegian nature that is under-explored. They represent a part of nature where conditions are extreme and where we expect to find a lot of new and exciting biology,” UiB spokesman Dag Rune Olsen said.

9. Incredible Never-Before-Seen Ice Finger Of Death Caught On Film For The First Time

There are no limits to the powers of nature. We live on an amazing planet surrounded by incredible natural forces that are not only beautiful, but sometimes very frightening.

Scientists have never been able to see the terrifying phenomenon Ice Finger of Death before. At least not until now…

The never-before-seen icy finger of death evokes feelings of awe and terror.

This creepy icy phenomenon is caused by cold, sinking brine, which is more dense than the rest of the sea water.

10. Enigmatic Ancient Underwater Ruins

These ancient underwater remains serve as a reminder of how vulnerable we are and how fast Mother Nature can end our existence.

To date, it is estimated that we have explored only 3 to 5 percent of the ocean floor. With so much territory still left to explore, we can only imagine the discoveries yet to come! Here are just a few examples of remarkable ancient underwater discoveries.

11. Underwater Pyramid-Shaped Structure Discovered

Researchers have discovered an underwater pyramid 60 meters high and 8000 meters square base between the islands of Terceira and São Miguel.

The perfectly squared structure, which is believe it’s not of natural origin, was sighted by a private yacht owner, Diocleciano Silva, during a recreational trip.

12. Giant Underwater Canyon Zhemchug Can Only Be Seen Entirely From Space

Hidden beneath all that water are some of the biggest natural formations on earth.

Deep underwater we find the longest mountain ranges, the tallest volcanoes and the deepest canyons.

We might think that Grand Canyon is big, but it is nothing compared to Zhemchug that is so huge it can only be seen entirely from space!

Zhemchug Canyon is a giant underwater canyon located in the middle of the Bering Sea.

It is deeper than the Grand Canyon (1.83 km deep) at 2.6km deep. Zhemchug Canyon is the largest submarine canyon in the world, based on drainage area (11,350 km2) and volume (5800 km3).

13. Colossal squid with colossal eyes

What did you expect? Would a colossal squid have anything but eyes big enough to generate a few over-the-top superlatives? Probably not – but still, when researchers thawed out this squid in New Zealand, the wow factor was undeniable. The creature’s eye measured about 11 inches across; its lens was the size of an orange. Scientists suspect the big eye allows the huge squid to capture a lot of light in the dark depths in which it hunts. The squid weighed about 1,000 pounds when caught in the Antarctic’s Ross Sea and measured 26 feet long. Scientists believe the species, which can descend to 6,500 feet, may grow as long as 46 feet.
