When was the 5th ocean discovered?
The fifth ocean was first recognized by the National Oceanic and Atmospheric Administration (NOAA) and given the name “Southern Ocean'' by the U.S. Boards on Geographic Names in 1999.
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean.
National Geographic decided to designate the Antarctic waters as its own ocean (instead of merely southern parts the Atlantic, Indian and Pacific) to bring awareness to, and promote conservation of the waters. But also because of its unique attributes, which scientists and geographers have long recognized.
The IHO published the third edition of Limits of Oceans and Seas (S-23), the global authority on the names and locations of seas and oceans, in 2000. The third edition in 2000 established the existence of the Southern Ocean as the fifth world ocean.
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase 'Seven Seas' is uncertain, although there are references in ancient literature that date back thousands of years.
Earth has a sixth ocean, a new study suggests, but not where you can see. It's hundreds of kilometres below the surface. The international study published in Nature Geoscience says this vast reservoir of water is located in the so-called transition zone between the upper and lower mantle at a depth of 410 to 660 kms.
95% of the ocean is unexplored and has never been seen by human eyes. You might be asking yourself: Why is that? First of all, ocean exploration technology is relatively new.
But a new study published in Nature Geoscience suggests there is a sixth ocean spanning the globe around 400 miles beneath the surface, at a boundary layer between the Earth's upper and lower mantle.
The ocean formed billions of years ago.
Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean.
In modern times, the seven seas refer to regions of Earth's five oceans—the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans.
Do oceans cover 1/3 of the Earth?
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water.
Earth may have been a water world 3 billion years ago. Calculations show that Earth's oceans may have been 1 to 2 times bigger than previously thought and the planet may have been completely covered in water.
Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
The Earth has finally attained popular recognition for its fifth ocean, with a decision by the National Geographic Society to add the Southern Ocean around Antarctica to the four it recognizes already: the Atlantic, Pacific, Indian and Arctic oceans.
The new ocean extends in a ring from Antarctica's coastline to 60 degrees south latitude, according to National Geographic, and differentiates from other oceans in its designation by current, not by continent.
Yes, Y e s , the Arctic Ocean is the coldest ocean, even colder than the waters surrounding Antarctica. Since the Arctic ocean always has sea ice even during summer, the temperature of the surface is relatively constant near the freezing point of seawater.
The waters of the Pacific Ocean comprise the world's largest heat reservoir, by far, and it is the warmest ocean, overall, of the world's five oceans. (The other oceans are the Arctic, Antarctic and Indian Oceans.)
A “supercoolometer”, a device that sounds like it should be used to measure hipsters, has found the coldest seawater on Earth, under Antarctic sea ice.
8th & Ocean is an American reality series about a group of models living in Miami, Florida that premiered on MTV on March 7, 2006. The series aired for ten episodes, ending its run on May 9, 2006. The creators of 8th & Ocean are also responsible for Laguna Beach, a show also airing on MTV.
The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface. Try to refrain from imagining expanses of underground seas: all this water, three times the volume of water on the surface, is trapped inside rocks.
Is the ocean ever ending?
While the ocean seems vast and unending, it is, in fact, finite; as the climate continues to change, we are learning more about those limits.
Sea level along the U.S. coastline is projected to rise, on average, 10 - 12 inches (0.25 - 0.30 meters) in the next 30 years (2020 - 2050), which will be as much as the rise measured over the last 100 years (1920 - 2020).
Currently, less than ten percent of the global ocean is mapped using modern sonar technology. For the ocean and coastal waters of the United States, only about 35 percent has been mapped with modern methods.
“By 2050, moderate flooding — which is typically disruptive and damaging by today's weather, sea level and infrastructure standards — is expected to occur more than 10 times as often as it does today,” said Nicole LeBoeuf, NOAA National Ocean Service Director.
The crime spree is being called a real-life "Ocean's Eleven" and seemed to be ripped from the pages of a Hollywood script. The group is comprised of acrobats, strong-men and electronics experts -- the type of dream team George Clooney would assemble in the movie.

No more fish
The world's oceans could be virtually emptied for fish by 2048. A study shows that if nothing changes, we will run out of seafood in 2048. If we want to preserve the ecosystems of the sea, change is needed.
One of the biggest challenges of ocean exploration comes down to physics. Dr. Gene Carl Feldman, an oceanographer at NASA's Goddard Space Flight Center, explains that the ocean, at great depths, is characterized by zero visibility, extremely cold temperatures, and crushing amounts of pressure.
Earth may have been a 'waterworld' without continents 3 billion years ago, study suggests. Around 3 billion years ago, Earth may have been covered in water – a proverbial "waterworld" – without any continents separating the oceans.
Why do they say 7 seas?
The ancient Romans called the lagoons separated from the open sea near Venice the septem maria or seven seas. Most current sources state that “seven seas” referred to the Indian Ocean, Black Sea, Caspian Sea, Adriatic Sea, Persian Gulf, Mediterranean Sea, and the Red Sea.
Today we feature the Dead Sea, situated between Israel and Jordan, and forming part of the border between the two countries. The Dead Sea is fed mainly by the Jordan River, which enters the lake from the north. Several smaller streams also enter the sea, chiefly from the east.
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins.
Drinking seawater can be deadly to humans.
Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.
In fact, 65% of our planet remains unexplored, most of which lies beneath the oceans. Literally anything could be down there, and we wouldn't know.
When the ice melted, sediments formed huge river deltas on top of the shelf, and fresh water got trapped there in scattered pockets. Later, sea levels rose. Up to now, the trapping of such “fossil” water has been the common explanation for any fresh water found under the ocean.
Don't worry. The oceans aren't going to dry up. At least not any time soon, so no need to add it to the list of things to worry about. But, what would our planet look like if they did?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.
Currently, the most favored explanation for where the Earth got its water is that it acquired it from water-rich objects (planetesimals) that made up a few percent of its building blocks. These water-rich planetesimals would have been either comets or asteroids.
Challenger Deep is the deepest point in the world ocean. Located within the already-deep Mariana Trench in the western Pacific Ocean, the actual deepness of Challenger Deep strains the imagination. We'll take a look at some bizarre ways to consider this depth, but first we'll explore why Challenger Deep...is deep.
How far underwater is it dark?
Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic zone exists in depths below 1,000 meters. Sunlight does not penetrate to these depths and the zone is bathed in darkness.
The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
Scientists were astonished after they found a rare 'warty' octopus and 'zombie' sea sponge in deep sea footage. The video, which was captured by marine explorers in the US, showed two profoundly rare sights from underneath the ocean surface.
The Gerlache Strait lies off the west coast of the Antarctic Peninsula, in the large band of ocean around Antarctica that has been reclassified as the Southern Ocean by National Geographic cartographers. The strait would once have been considered part of the Pacific.
The Southern Ocean, also known as the South Polar Ocean (and formerly the Antarctic Ocean), is the body of water encircling the continent of Antarctica.
The Atlantic is expanding by a couple of inches a year. The Atlantic Ocean is getting wider, shoving the Americas to one side and Europe and Africa to the other.
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans. The exact origin of the phrase 'Seven Seas' is uncertain, although there are references in ancient literature that date back thousands of years.
The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.
Despite its size and impact on the lives of every organism on Earth, the ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans.
Scientists have found the sixth ocean on Earth, but it's not on the surface of the planet. By India Today Web Desk: There are five oceans on Earth: the Atlantic, Pacific, Indian, Arctic, and Southern Ocean.
What will be in the ocean at 2050?
The amount of plastic in the ocean is expected to double in the next 15 years, and by 2050 there could be more plastic than fish in the sea (by weight). There are giant plastic islands floating on the ocean surface, and beaches around the world are increasingly littered with plastic rubbish even in the Arctic.
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
Some geographers point to the Age of Discovery and suggest that the seven seas represent the Atlantic, Pacific, Arctic, and Indian Oceans, as well as the Mediterranean Sea, the Caribbean, and the Gulf of Mexico.
It's often said that 95% of the Earth's ocean floor is unexplored. The National Oceanic and Atmospheric Association (NOAA) puts that figure at more than 80%.
There are various reasons why someone may develop a fear of the ocean. A bad experience with water may lead to a fear response and phobia. For instance, if you nearly drowned while swimming in a lake or saw a shark in the ocean, you may develop an intense fear. Phobias can also develop without any experience or trauma.
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
