The average depth of the ocean is about 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.
What is the deepest ocean in the world?
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
Have we reached the bottom of the ocean?
2019: Victor Vescovo reached a deeper part of Challenger Deep at 35,853 feet, breaking the record for the deepest dive in DSV Limiting Factor. His dive was part of the Five Deeps Expedition to reach the bottom of every ocean on Earth.
More than 80% of the ocean remains unexplored. And because it’s difficult to protect what we don’t know, only about 7% of the world’s oceans are designated as marine protected areas (MPAs).
Which is deeper the sea or the ocean?
Seas are generally much shallower than oceans, just as they are smaller. Regardless, some seas have great depths, such as the Caribbean, which is the deepest in the world at 7,686 meters—a number significantly higher than the average depth of the ocean.
The Mariana Trench Is the Deepest Point on Earth and We Have No Idea What All Is Down There. The Terrifyingly Deep Great Blue Hole. The Corryvreckan Maelstrom Is a Permanent, Violent Whirlpool. The Remains of a Devastating WWII Battle Lie at the Bottom of the Chuuk Lagoon. The Devil’s Sea Is the Bermuda Triangle’s Twin.
How much of the ocean is discovered?
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.
What is under the sea floor?
Features of the ocean include the continental shelf, slope, and rise. 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.
Ocean salt primarily comes from rocks on 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. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
Are all seas connected to the ocean?
By definition, a sea is a smaller part of an ocean and is typically partially contained by an area of land. Therefore, all seas are found in areas where the ocean and land meet. Seas are typically partially enclosed by land.
What is the biggest in the 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. All of the world’s continents could fit into the Pacific basin.

The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam. Fish living closer to the surface of the ocean may have a swim bladder filled with air.
