Editor's Notes
Lost for 1,600 years, the kingdom of Cleopatra was discovered off the shores of Alexandria, Egypt. Cleopatra VII Philopator, known to history as Cleopatra, was the last pharaoh of Ancient Egypt.
She was a member of the Ptolemaic dynasty, a family of Greek origin that ruled Egypt after Alexander the Great's death during the Hellenistic period.

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.
An underwater structure is oriented upon the four cardinal directions and was discovered at a depth of 40 meters.
Most recently, archeologists from the Portuguese Association of Archeological Research (APIA) have identified archeological evidence on Pico island that supports their belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years.
Click on image to enlargeThe evidence comprises of a great variety of protohistoric pyramidal rock structures, some of them 13 meters tall.
The structures may have been built according to an oriented plan, aligned with the summer solstices, which suggests they were built with an intended purpose. The vertex of the pyramid was facing north and south, like Giza pyramids in Egypt.
Has a discovered underwater structure any connection with legendary Atlantis? Around 350 BC, Plato, a mathematician and philosopher in Classical Greece and student of Socrates, wrote about a beautiful island in the Atlantic Ocean that disappeared under the ocean waves in one day and one night. For centuries people have been searching for this mysterious lost city, Atlantis.
The Azores islands - located roughly in the centre of the Atlantic ocean - were discovered uninhabited by the Portuguese around 1427. They were formed by the tectonic activity along the centre of the ocean floor.
There are are nine islands in total, and for a long time, there were reports about the presence of ancient structures and artefacts on the islands.
We continue to explore amazing places on our beautiful planet.
This time we take a journey deep beneath the oceans. 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).
Named after a Soviet research ship and a word meaning "pearl," Zhemchug Canyon cuts into the ocean floor at the western edge of the Continental Shelf, "one of the flattest and smoothest places on the planet," Dan O'Neill wrote in his book, The Last Giant of Beringia.
"Its slope, at no more than three or four inches per mile, is almost unmeasurable!"
More about this programme: http://www.bbc.co.uk/programmes/b012t6ly Zhemchug Canyon is in the Bering Sea and is the largest canyon in the ocean it has a vertical drop over 2500 metres.
This is what Zhemchug Canyon looks from space.
It is normally hidden by the pacific Ocean, but the Zhemchug is so wide it is impossible to see from one side to the other, unless you are above the curvature of the Earth.

The endangered short-tailed albatross congregates to feed over the surface waters of the canyon.Marine mammals such as Northern Fur Seal feed in the canyon as do many species of whales.
Habitat-forming invertebrates such as Bubblegum Coral, bamboo coral, soft corals, Hexactinellid sponges, and other sponges have been identified during trawl surveys in the canyon.
It is where the Opilio (Snow Crab) crab and Baridi crab can be found Opilio crab are shown in the Opilio season on Deadliest Catch. Only in the last five years have scientists have begun to plumb the depths of Zhemchug, and we still have virtually no information on what marvels it may conceal.
Our oceans are greatly unexplored and full of secrets. Deep beneath the waters there are marvelous ruins of lost ancient civilizations.
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.
Dwaraka - Lord Krishna's Lost City
For a long time, Krishna's legendary city of Dwaraka was considered to be nothing but a myth.
Sophisticated Vimanas Over Dwarka - Pre-Harappan City That Could Rewrite The History Of The WorldHowever, not so long ago a group of Indian scientists accidentally discovered the lost city of Dwaraka, submerged off the north western coast of India near the Gulf of Cambay or Khambat.
After so many years it turned out that the 12,000 year old city of Dwaraka was not a myth at all, but a real place that existed in the distant past.
"The sea, which had been beating against the shores, suddenly broke the boundary that was imposed on it by nature. The sea rushed into the city. It coursed through the streets of the beautiful city.
The sea covered up everything in the city. I saw the beautiful buildings becoming submerged one by one. In a matter of a few moments it was all over.
The sea had now become as placid as a lake. There was no trace of the city. Dwaraka was just a name; just a memory..." - Mahabharata

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. It forms a brinicle as it contacts warmer water below the surface.
How does a brinicle form?
"Freezing sea water doesn't make ice like the stuff you grow in your freezer. Instead of a solid dense lump, it is more like a seawater-soaked sponge with a tiny network of brine channels within it.
The brinicle that causes destruction resembles a finger and is called "ice finger of death." Image credit: BBC
In winter, the air temperature above the sea ice can be below -20C, whereas the sea water is only about -1.9C. Heat flows from the warmer sea up to the very cold air, forming new ice from the bottom. The salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.
The result is the brine sinks in a descending plume. But as this extremely cold brine leaves the sea ice, it freezes the relatively fresh seawater it comes in contact with. This forms a fragile tube of ice around the descending plume, which grows into what has been called a brinicle.
The ice finger phenomenon evokes a feeling of amazement and as well as fear. Image credit: BBC
Brinicles are found in both the Arctic and the Antarctic, but it has to be relatively calm for them to grow as long as the ones the Frozen Planet team observed," explained Dr Mark Brandon Polar oceanographer, at the Open University.
Caught on film for the first time ever in Antarctica
The unusual phenomenon was filmed for the first time by cameramen Hugh Miller and Doug Anderson for the BBC One series Frozen Planet.
Capturing the event on tape was not an easy task. The crew battled brutal conditions, technical challenges, and even seal attacks.
"Because there have been so few studies on the brinicles, it's really, really difficult to tell when and exactly how they are going to form," Kathryn Jeffs, "Frozen Planet" producer explained. "They do have a tendency to form when the ice is being disrupted, or in extremely cold conditions, which disrupt the inner channels and sets in motion the flow of brine."
The movie was made beneath the ice off the foothills of the volcano Mount Erebus, in water as cold as -2C, a remote volcano in Antarctica.
Rivers under the sea can really exist! The ocean has many secrets, and underwater rivers are one them.
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.
This finding can help scientists to shed more light on how life manages to survive in the deep oceans away from the nutrient-rich waters found close to land.
The undersea river, which is up to 115 feet deep in places, even has rapids and waterfalls much like its terrestrial equivalents.

Scientists from the University of Leeds, used a robotic submarine to study a deep channel that had been found on the sea bed, and found a river of highly salty water flowing along the deep channel at the bottom of the Black Sea, creating river banks and flood plains much like a river on land.
Dr Dan Parsons, from the university's school of earth and environment, said: "The water in the channels is denser than the surrounding seawater because it has higher salinity and is carrying so much sediment."It flows down the sea shelf and out into the abyssal plain much like a river on land.
The abyssal plains of our oceans are like the deserts of the marine world, but these channels can deliver nutrients and ingredients needed for life out over these deserts.
"This means they could be vitally important, like arteries providing life to the deep ocean.
"The key difference we found from terrestrial rivers was that as the flow goes round the bend, the water spirals in the opposite way to rivers on land."
This in not the first time an undersea river has been discovered. Under the sea of Mexico, there is a river called 'Cenote Angelita'- It was discovered by Anatoly Beloshchin and his group of divers.
