Has a new ocean been discovered?
As of June 2021, the Southern Ocean—the body of water surrounding Antarctica—is recognized as the world’s fifth. The National Geographic Society for the first time named the Southern Ocean as the newest of Earth’s five oceans. Dive into what it means for conservation—and travelers.
How much of the ocean is discovered in 2021?
According to the National Ocean Service, it’s a shockingly small percentage. Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans.
Do we have a 5th ocean?
National Geographic, one of the world’s pre-eminent and most visible mapmaking groups, has officially decreed the existence of a fifth ocean. Called the Southern Ocean, it’s the body of water that surrounds Antarctica.
When was the 5th ocean added?
Soon after, the National Oceanic and Atmospheric Administration (NOAA) recognized the body of water as the fifth ocean in 1999 after the Board of Geographic Names approved the title, “Southern Ocean,” reports Paulina Firozi for the Washington Post.
How many oceans are there in 2021?
It’s time to update your maps, because the Earth now has a total of five oceans. Though accepted by scientists for some time, the Southern Ocean wouldn’t be found on any National Geographic maps – until now. Cartographers at the National Geographic officially recognised the fifth ocean on World Ocean Day, 8 June 2021.
What is the 6th ocean?
There are currently five oceans on our planet, but researchers have stated that a sixth ocean is forming. In Eastern Africa, lies the Afar Triangle — also called the Afar Depression.
Are there 5 or 7 oceans?
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. The Pacific, Atlantic, and Indian are the most commonly known. The Southern Ocean is the ‘newest’ named ocean.
Who named the oceans?
The ocean’s current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favorable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means ‘peaceful sea’.
Which is the deepest ocean?
Rank | Name | Ocean |
---|---|---|
1 | Challenger Deep | Pacific |
2 | Brownson Deep | Atlantic |
3 | Factorian Deep | Southern |
4 | (Unnamed deep) | Indian |
Is the ocean ever still?
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. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor.
How deep can humans go in the ocean?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
What did we find in the ocean 2020?
Scientists Discover a New Coral Reef
During an expedition off the coast of Australia, researchers aboard the Falkor, a vessel run by the Schmidt Ocean Institute, discovered a massive coral reef pinnacle that reached a height taller than the Empire State Building.
Why can’t we go to the bottom of the ocean?
“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.
What is the newest ocean called?
Starting on June 8, World Oceans Day, it will recognize the Southern Ocean as the world’s fifth ocean. “The Southern Ocean has long been recognized by scientists, but because there was never agreement internationally, we never officially recognized it,” says National Geographic Society Geographer Alex Tait.
Where is the ocean’s deepest point?
The average depth of the ocean is about 3,688 meters (12,100 feet). 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.
Are all oceans connected?
The salty water of the oceans covers almost three-quarters of the Earth’s surface. There are four different oceans on Earth: the Pacific, Indian, Atlantic, and Arctic Oceans. All the oceans are connected to each other. Water is always moving within and between the oceans in currents, tides, and waves.
How many seas are on Earth?
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern oceans.
What’s the five oceans?

- The Arctic Ocean. …
- The Southern Ocean. …
- The Indian Ocean. …
- The Atlantic Ocean. …
- The Pacific Ocean.
What is the smallest ocean?
The Arctic Ocean is the smallest of the world’s five ocean basins. A polar bear walks on the frozen surface of the Arctic Ocean. The freezing environment provides a home for a diverse range of creatures. With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States.
What is the biggest ocean?
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.
Is there a new ocean on Earth?
For the first time in over a century, there’s a new ocean on the map. That’s according to National Geographic, which Tuesday announced that it is officially recognizing the body of water surrounding the Antarctic as the Southern Ocean, making it the fifth ocean alongside the Arctic, Atlantic, Indian, and Pacific.
How does the ocean lose water?
Water evaporates from the surface of the ocean, mostly in warm, cloud-free subtropical seas. This cools the surface of the ocean, and the large amount of heat absorbed the ocean partially buffers the greenhouse effect from increasing carbon dioxide and other gases.
How are oceans divided?
Geographers divide the ocean into five major basins: the Pacific, Atlantic, Indian, Arctic, and Southern. Smaller ocean regions such as the Mediterranean Sea, Gulf of Mexico, and the Bay of Bengal are called seas, gulfs, and bays.
Where is the new ocean?
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.
What was the first ocean on Earth?
The First Oceans of the Hadean
According to the most recent scientific studies, an ancient ocean likely covered the entire planet 150 million years after the formation of Earth, about 4.4 billion years ago. Scientists know this through the discovery of ancient zircon crystals that were dated around this time.
How many sharks are in the ocean?
There are over 400 different species of shark. Some estimates suggest over a billion sharks in the ocean.
Which ocean is coldest?
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
How cold is the bottom of the ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F).
Is the ocean deeper than the sea?
Generally, the ocean is much deeper than the sea even if some seas can be almost as deep as big oceans. To give you a few examples, the depth of the Channel is 174m, the one of the North Sea is 700m and for the Black Sea it is 2,212m.
Who discovered the ocean?
Explorer Ferdinand Magellan named the Pacific Ocean in the 16th Century. Covering approximately 59 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.
Can the ocean freeze?
Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes.
How much pee is in the ocean?
The volume of the Atlantic Ocean is about 350 quintillion liters. That’s 350 and 18 zeroes. If every person on earth had the average amount of pee containing the average amount of urea into the Atlantic, there’d be just 60 parts per trillion of urea in the ocean.
Have we explored the bottom of the ocean?
But reaching the lowest part of the ocean? 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.
What bodies are part of the world ocean?
The five major oceans are the Pacific, Atlantic, Indian, Arctic, and Southern oceans.
How dark is it at the bottom of the ocean?
After the aphotic zone, there’s complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either.
How much of the earth is still unexplored?
Our oceans cover more than 70% of the Earth’s surface, but over 80% of them remain unexplored.
Can you dive down to see the Titanic?
An Undersea exploration company OceanGate Expeditions is giving a chance to dive in the Atlantic to witness and explore the world’s most famous and iconic shipwreck, The RMS Titanic. Fans and tourists can take a voyage to the Titanic in 2021 to witness the extremes of time and pressure.
What happens if you dive too deep?
This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain. Nitrogen narcosis. Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you’ve been drinking alcohol.
What is under the ocean floor?
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.
What was found in the ocean 2021?
Amazed researchers find mammoth tusk 10,000 feet under the sea. In July 2021, scientists discovered a three-foot-long tusk from an extinct Columbian mammoth some 10,000 feet beneath the ocean. Researchers collected the specimen off the California coast.
Is the ocean deeper than we think?
Yep, in a body of water 11 km deep, we humans only get to experience the first 100 metres or so. That’s not including some extraordinary people though, like Herbert Nitsch, who made it to 214 metres down on a single breath. Once we hit the 500-metre mark, this is the maximum dive depth for blue whales.
What is going on in the ocean right now?
Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans.
Where is the new 5th ocean?
National Geographic announced it was recognizing the body of water encircling the Antarctic as the Earth’s fifth ocean: the Southern Ocean.
Are oceans salt water?
Oceans cover about 70 percent of the Earth’s surface and about 97 percent of all water on and in the Earth is saline—there’s a lot of salty water on our planet.
Where did the water in our oceans come from?
After the Earth’s surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries. As the water drained into the great hollows in the Earth’s surface, the primeval ocean came into existence. The forces of gravity prevented the water from leaving the planet.
Has anyone been to bottom of Mariana Trench?
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.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
What lives in Mariana Trench?
- Dumbo Octopus.
- Deep-sea Dragonfish.
- Barreleye Fish.
- Benthocodon.
- Seadevil Anglerfish.
- Goblin Shark.
- Deep-sea Hatchetfish.
- Frilled Shark.
Which ocean is not salty?
The ocean around Antarctica has a low salinity of just below 34ppt, and around the Arctic it is down to 30ppt in places. Thawing icebergs add freshwater – icebergs that have broken off ice sheets formed over land do not contain salt, and the freezing of seawater into ice floes removes more salt.
What ocean is most traveled?
The Atlantic Ocean is the second largest of Earth’s five oceans, the most heavily traveled, and the most intensely studied, principally because of its importance in ship traffic between Europe and North America.
Is sea level 0?
Most people are surprised to learn that, just as the surface of the Earth is not flat, the surface of the ocean is not flat, and that the surface of the sea changes at different rates around the globe. For instance, the absolute water level height is higher along the West Coast of the United States than the East Coast.
Why is the sea salty?
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
What are ocean names?
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. The Pacific, Atlantic, and Indian are the most commonly known.
Where is the Black Sea?
The Black Sea is located at the southeastern extremity of Europe. It is bordered by Ukraine to the north, Russia to the northeast, Georgia to the east, Turkey to the south, and Bulgaria and Romania to the west.
