According to Sanskrit literature, there was a holy city called Dwarka, founded by Lord Krishna, one of Hinduism’s major deities. As legend tells it, the city was engulfed by the rising Arabian Sea, causing it to sink and maintain its “myth” status for centuries. But in 1985, archaeologists and Indian Navy divers discovered what they believed to be the remains of this ancient city, dating back to 1500 B.C.
The city, located off the coast of India’s western state of Gujarat, unearthed some seals, artifacts and stone structures that archaeologists say corroborate the descriptions given of the sacred city of Dwarka in ancient Hindu texts.
An Underwater River in the Black Sea
In August 2010, scientists from the University of Leeds discovered an underwater river in the Black Sea. The current of particularly saline water flows in through the Bosphorus Strait and runs across the bottom of the Black Sea. Aside from how amazing it is to imagine there is a massive river flowing under the sea, what makes this discovery even more baffling is the size of the river.
Estimated to be around 10 times larger than the Rhine, Europe's biggest river, this undersea river would actually be the world's 6th largest if it were on land! And just like any river on land, this mysterious body of water even has river banks and flood plains, and goes up to 115 feet deep in some places, with a mixed flow of fresh and salt water. This discovery has been an immense help to scientists that are trying to understand how any form of life manages to survive at such ocean depths.
In the middle of the Bering Sea, about 170 miles northwest of St. Paul Island in Alaska, lies one of nature's most beautiful underwater discoveries - the Zhemchug Canyon. Considered the deepest and largest submarine canyon in the world, the Zhemchug Canyon is even deeper, and 20 percent longer, than its on-land counterpart, the majestic Grand Canyon.
The Zhemchug Canyon, named after a Soviet research ship, plunges to a depth of more than 8,500 feet, and can be seen entirely from outer space. The canyon boasts a wide and colorful variety of life-forms, and even after much research, many of the organisms that originate and evolve at such depths remain a fascinating mystery to many scientists.
The Vasa Shipwreck
The Vasa was a Swedish warship that sank on her maiden voyage in 1628. It wasn't until the late 1950s that the Vasa shipwreck was discovered just outside the Stockholm harbor. Finally, in 1961, the Vasa was salvaged with an almost intact hull. The shipwreck was taken to a temporary museum until 1988, when it was transferred to the Vasa Museum, a maritime museum in Stockholm.
The Vasa shipwreck, and the artifacts discovered with it, have become one of Sweden's most visited tourist spots, having been seen by over 35 million visitors since 1961. The Vasa has not only become a symbol of the Swedish Empire, but also provided incredible insight into what naval warfare, shipbuilding and everyday life looked like back in 17th-century Sweden.
The Spanish San Jose Galleon
On June 8th, 1708, the Spanish galleon San Jose was sunk by the British after a terrible battle. The 62-cannon sailing ship went down into the darkness of the Caribbean Sea, and took almost 600 people and $20 billion worth of gold, silver and jewels down with it.
The galleon wouldn't be found for centuries, until in 2015, the Colombian government claimed it had found the ship off the coast of Cartagena, a city in Colombia. Unfortunately, the shipwreck is still underwater, since its extremely valuable cargo has started a nasty custody dispute over who the galleon's riches belong to.
