Name the deepest ocean in the world

On March 25, 2012, filmmaker and National Geographic Explorer James Cameron became the first person to make a solo voyage to the deepest point on Earth. His 24-foot tall submersible, the Deepsea Challenger, reached 35,756 feet (10,898 meters) after a 2.5-hour descent. Unlike Piccard and Walsh's brief visit, Cameron spent more than 3 hours exploring the trench, although his attempts to take biological samples were hampered by technical glitches. Kennedy, Jennifer.

The deepest spot in the Mariana Trench is a valley called the Challenger Deep, located at the Mariana Trench's southern end, according to the National Oceanic and Atmospheric Administration (NOAA). According to NOAA, the Challenger Deep extends about 35,876 feet (10,935 meters) below the surface. That makes it about 7,000 feet (2,100 m) deeper than Mount Everest is tall, NOAA noted. NOAA's estimate comes from a 2021 study in the journal Deep Sea Research Part I: Oceanographic Research Papers, based on data from a 2020 voyage. However, there are many other estimates of the depths of the Challenger Deep. The first crewed mission there, in 1960, returned an estimate of 35,797 feet (10,911 m), according to Guinness World Records. Since then, recent estimates have included 36,069 feet (10,994 m) and 36,036 feet ( 10,984 m). Why is estimating the depth of the Challenger Deep so challenging? "Fundamentally, it is difficult because it is so deep," Cmdr. Sam Greenaway of the NOAA Corps and l...

The ocean is a vast body of water covering around 72% of our planet's surface. Image credit: Alex Stemmer/Shutterstock.com • According to NOAA, there are five ocean basins in the world - Arctic, Atlantic, Indian, Pacific, and Southern. However, there is only one Global Ocean. • The ocean covers about 71% of the surface of the Earth. • As per estimates, 97% of the water on our planet is found in the ocean. • The ocean remains one of the most unexplored places on Earth. Approximately, 80% of the ocean hasn't been mapped or explored. The Arctic Ocean is located in a polar climatic zone characterized by frigid year-round temperatures. Long hours of darkness engulf the ocean during winters and summers are characterized by continuous daylight. The marine habitat of the Arctic Ocean is a fragile ecosystem that is highly susceptible to slight disruptions in weather. Threatened species of whales and walruses inhabit the ocean. Plant life in the Arctic Ocean is scarce except for abundant volumes of phytoplanktons. The Lion’s mane jellyfish and the banded gunnel are among the few species of marine creatures inhabiting the Arctic Ocean’s waters. The ocean bed also hosts petroleum and natural gas fields, polymetallic nodules, and placer deposits. Like other oceans of the world, climate change threatens to adversely affect the marine ecosystem of the Arctic Ocean. As per research, the Arctic might become ice-free by 2040. This transformation would load the Arctic with large volumes of m...

But the deep sea remains largely unexplored. As you dive down through this vast living space you notice that light starts fading rapidly. By 650 feet (200 m) all the light is gone to our eyes and the temperature has dropped dramatically. Dive deeper and the weight of the water above continues to accumulate to a massive crushing force. Any light still filtering down has diminished to appear completely black, leaving only animals and bacteria to produce the light found here. By 13,000 feet (4,000 meters), the temperature hovers just below the temperature of your refridgerator. At this depth, we’ve reached the average depth of the deep-sea floor, a place that may start to get a little muddy. The further we dive down from the surface, the less new food is available, making the fight to survive that much more challenging. Despite these harsh conditions, there is li...

Covering more than 71 percent of the Earth's surface, an incredible 99 percent of the living space on the planet is contained in them. Yet, for all of that, we still know so little, having explored less than 5 percent. We have explored more of the moon's surface than we have the oceans! From the Mid-Oceanic Ridge which divides the Atlantic Ocean into two to the depths of the Challenger Deep at the bottom of the Pacific Ocean, the salty depths of the world's oceans remain a mystery to humanity. Here are the world's oceans, ranked by depth: Pacific Ocean. The Pacific Ocean is not only the deepest ocean, with an average depth of 13,740 feet (4,188 meters), but it also contains the deepest point on the planet, at 36,070 feet (10,994 meters). The Challenger Deep is part of the Mariana Trench, a deep groove in the sea floor where one tectonic plate is being subducted under another tectonic plate. The water here is deep enough to cover the top of Mount Everest miles below the surface! Atlantic Ocean. Coming in as the second deepest ocean is the Atlantic, with an average depth of 12,254 feet (3,735 meters). The deepest part of the Atlantic is the Milwaukee Deep of the Puerto Rico Trench, which lies 28,374 feet (8,648 meters) below the waves. This subduction zone was responsible for the 8.1 magnitude earthquake that struck the region in 1953 and the subsequent tsunami. Indian Ocean. Although the Indian Ocean has a slightly deeper average depth than the Atlantic, at 12,740 feet (3,8...
