Is there anywhere deeper than Challenger Deep?
After all, it was only in 1997 that researchers discovered the Sirena Deep, which is also located in the Mariana Trench, which they measured at 35,210 feet, less than a thousand feet shallower than the Challenger Deep..
How many miles is the Challenger Deep?
200 milesThe distance between the surface of the ocean and the trench’s deepest point—the Challenger Deep, which lies about 200 miles (322 kilometers) southwest of the U.S. territory of Guam—is nearly 7 miles (11 kilometers).
What part of the ocean is the deepest?

What would happen to a human at the bottom of the Mariana Trench?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.
Why did James Cameron explore the Mariana Trench?
The need to explore In response to a girl in the audience who asked if there was more to see in the Mariana Trench, Cameron used a metaphor to emphasize how little of the ocean floor in these deep underwater canyons has been observed with human eyes.
Why is Mariana trench so deep?
The Mariana Trench isn’t really the deep, narrow furrow that the word “trench” implies. Rather, the abyss marks the location of a subduction zone. … One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old.
What was found at the bottom of the Mariana Trench?
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. … While the Mariana Trench may seem like a dark, lifeless pit, it hosts more life than you might think.
Why do deep sea fishes not get crushed by pressure on the sea floor?
Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies, which means they don’t get crushed.
Has anyone been to the bottom of the Mariana Trench?
Explorer Reaches Bottom of the Mariana Trench, Breaks Record for Deepest Dive Ever. The submersible reaches the bottom of the Challenger Deep in the Mariana Trench. Explorer and businessman Victor Vescovo descended 35,853 feet (10,927 meters) into the Pacific Ocean, breaking the record for deepest dive ever.
Is the challenger deep part of the Mariana Trench?
Toward the southern end of the Mariana Trench lies the Challenger Deep. It sits 36,070 feet below sea level, making it the point most distant from the water’s surface and the deepest part of the Trench.
What’s at the bottom of Challenger Deep?
Drazen believes that this is about as deep as any fish can go. If he’s right, there are no fish at the bottom of the Challenger Deep. But there’s plenty more than fish in the sea. Despite the lethal conditions, James Cameron’s dive revealed a plethora of animals at the bottom of the ocean.
Why is the Challenger Deep so deep?
The great depth of the Challenger Deep is due to active steepening of the subducting slab along a zone of weak coupling with the overriding plate in the southern part of the Mariana Trench tearing away from the northern part (Fryer et al., 2003; Gvirtzman and Stern, 2004). … …
What is the deepest place on Earth?
Challenger DeepIn 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.
How cold is the Mariana Trench?
The temperature at the bottom is 1 to 4 °C (34 to 39 °F). In 2009, the Marianas Trench was established as a United States National Monument. Monothalamea have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of 10.6 kilometres (6.6 mi) below the sea surface.
Is there a Megalodon in the Mariana Trench?
It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it. ‘
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.
Do we know how deep the ocean is?
Today scientists know that on average the ocean is 2.3 miles (3.7 km) deep, but many parts are much shallower or deeper. To measure depth they use sonar, which stands for Sound Navigation And Ranging.
How long does it take to reach Challenger Deep?
about 90 minutesPre-expedition estimates put the Challenger Deep descent at about 90 minutes. (Animation: Cameron’s Mariana Trench dive compressed into one minute.) By contrast, some current remotely operated vehicles, or ROVs, descend at about 40 meters (130 feet) a minute, added Stern, who isn’t part of the expedition.
What lives at the bottom of the ocean?
Frilled Shark. Humans rarely encounter frilled sharks, which prefer to remain in the oceans’ depths, up to 5,000 feet (1,500 meters) below the surface. … Giant Spider Crab. … Atlantic Wolffish Pair. … Fangtooth Fish. … Six-Gill Shark. … Giant Tube Worms. … Vampire Squid. … Pacific Viperfish.More items…•
Are there fish in the Mariana Trench?
Meet the deepest fish in the ocean, a new species named the Mariana snailfish by an international team of researchers that discovered it. The Mariana snailfish (Pseudoliparis swirei) thrives at depths of up to about 8,000 meters (26,200 feet) along the Mariana Trench near Guam.
How deep can a human dive before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
