Gakkel Ridge. Running between Greenland and Siberia, the Gakkel ridge is the deepest mid-ocean ridge in the world, reaching depths of up to three miles. It's no surprise then that the darkest corners of the Gakkel Ridge remain largely unexplored.
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.
What was found at the bottom of the ocean that was so surprising?
It was a group of female octopuses, of the genus Muusoctopus, guarding clutches of eggs they'd carefully attached to the cracks and crevices snaking across the seafloor. It was odd, but the scientists weren't there to admire the sea life. The scientists had found their mark, but it was covered in octopuses.
What is found at the bottom of the ocean?
But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong. A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong.

How much of the ocean has been explored 2021?
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. That doesn't seem like it could be true. The oceans account for 70 percent of Earth's surface.
How much of the ocean is explored in 2021?

Is there a hidden world in the ocean?
The hidden world under the sea: Scientists find 'parallel universe' of life INSIDE the basalt of the oceanic crust. A parallel universe of life exists hidden beneath our planet's ocean floors and could help us search for life on other planets, new research claims.
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.

There's as much water inside the earth as there is in all of the oceans. Down beneath the mantle is the core, but it's in the mantle that you'll find our secret sixth ocean.

Which part of Earth is still undiscovered?
Antarctica is a continent that's mostly uninhabited and filled with unexplored areas. Most scientists and researchers who spend time in Antarctica inhabit areas around research stations because the extreme landscape is largely unlivable.
Is there life under the sea?
Researchers have recently found living microorganisms thriving below the Oceanic floor, deep in Earth's lower crust in volcanic rocks. “The lower ocean crust is one of the last frontiers of the exploration for life on Earth,” explained microbiologist Virginia Edgcomb.May 8, 2020

What did scientists find at the bottom of the Atlantic ocean?
A gigantic freshwater aquifer is hiding under the salty Atlantic Ocean, just off the northeastern coast of the United States, a new study finds. This aquifer may contain about 670 cubic miles (2,800 cubic kilometers) of slightly salty water (we'll explain its slight saltiness later).
How much of the ocean has not been discovered 2020?
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.
