Deepest point of ocean

The vast world’s oceans hold unprecedented mysteries, among them being deep trenches. Ocean beds have valleys, plateaus, flatlands, and mountains, similar to the earth’s surface. Such features have led to the deepness of the world’s oceans, most of which haven’t been explored. The trenches are created when shifting tectonic plates slip below other plates. Bottom Line These depths go up to several kilometers as the underwater features are believed to be more enormous than what we see on land. Areas that go more than 200 meters or about How Are Ocean Trenches Formed? Ocean trenches are formed by the subduction process where tectonic plates converge. It may involve two or more plates, and the denser plate is subducted beneath the lighter one. This leads to the bending of the seafloor and the lithosphere, creating a long and narrow V-shaped depression. The oceans are the deepest in the world and are located in every ocean basin worldwide. Ocean trenches are located in the hadalpelagic zone, the deepest layer of the ocean. The aura in the ocean trenches is composed of minimal or no sunlight, intense pressure, and frigid temperatures. However, some unique species still thrive in the deepest parts of the ocean. The deepest point in the ocean is the maximum depth that can be defined, and here are the ten deepest points of the world’s oceans. 1. Mariana Trench (Challenger Deep) The trench is located in the western Pacific, between Australia and Japan, and runs to a depth of 10.91 k...

On the deepest dive ever made by a human inside a submarine, a Texas investor found something he could have found in the gutter of nearly any street in the world: litter. Victor Vescovo, a retired naval officer, made the unsettling discovery as he descended nearly 35,853ft (10,927 meters) to a point in the Pacific Ocean’s Mariana Trench that is the deepest place on Earth, his expedition said in a statement on Monday. His dive went 52ft (16 meters) lower than the previous deepest descent in the trench in 1960.

Photograph: HANDOUT/Reuters Vescovo, the Dallas-based co-founder of Insight Equity Holdings, a private equity fund, found the manmade material on the ocean floor and is trying to confirm that it is plastic, said Stephanie Fitzherbert, a spokeswoman for Vescovo’s Five Deeps Expedition. Why is plastic being demonised? Since the 1950s, 8.3bn tonnes of plastic has been produced. Plastic is seen as a versatile, indispensable product, but the environmental impact is becoming more stark. Plastic is now so pervasive that recycling systems cannot keep up and the leakage into the environment is such that by 2050 plastic in the ocean will outweigh fish. In 2017 scientists found plastic fibres in tap water, and plastic has been found in the stomachs of sea creatures in the deepest part of the ocean. Most plastic waste ends up in landfill sites or leaks into the natural...

Martin Luther King Jr.: The iconic civil rights leader There are deep realms on our planet that seem almost extraterrestrial. Translucent fish flit back and forth while strange, flower-like crinoids sway in the water. But of all the submarine canyons and trenches out there, what are the deepest, darkest spots in each of the world's five oceans? © ratpack223 via Getty Images A digital rendering of the Mariana Trench, the deepest place in the Pacific Ocean and the world. The deepest place in the Pacific Ocean (and on Earth) is the Mariana Trench. The trench's deepest point is the Challenger Deep near the U.S. territory of Guam — a plunge that's almost 36,000 feet (10,973 meters) below the water's surface, according to a 2019 study published in the journal Earth-Science Reviews. The deepest region in the Atlantic Ocean is the Milwaukee Deep in the 27,585-foot-deep (8,408 m) axis of the Puerto Rico Trench. Coming in at 23,917 feet (7,290 m) deep is a nameless region at the bottom of the Indian Ocean. The Southern Ocean (also known as the Antarctic Ocean) goes all the way down to 24,229 feet (7,385 m) in the South Sandwich Trench, and the Arctic Ocean goes down to 16,000 feet (4,877 m) deep at Molloy Deep in the Fram Strait. Such areas are far from the reach of the sun and may appear to be nothing but gaping mouths of impenetrable darkness. But what do scientists know about these final frontiers? The Mariana Trench The Mariana Trench is a 1,580-mile-long (2,542 kilometers) ocea...

The waters of the Southern Ocean favor the growth of diatoms and other single-celled plants. Krill are the most important organism in the higher food chain. Animals on the sea bottom include hydrozoans, corals, sponges, bryozoans, sea spiders, isopods, polychaetes, eelpouts, sea snails, rat-tailed fishes, codlike fishes, hagfish, and skates. Southern Ocean, also called Antarctic Ocean, body of Physiography The Southern Ocean covers 8,479,000 square miles (21,960,000 square km), and it holds 17,226,000 cubic miles (71,800,000 cubic km) of water. It has an average depth of 10,728 feet (3,270 metres) and a maximum depth of 24,383 feet (7,432 metres) in the South Sandwich Trench, southeast of the island of South Georgia.

The snailfish — of the genus Pseudoliparis, which resemble a ghoulishly large tadpole — was a small juvenile that has greater capabilities of living at such depths, the opposite of other deep-sea fish. They were found in the Izu-Ogasawara Trench south of Japan during a two-month voyage by a joint Australian-Japanese scientific expedition. The record-breaking discovery was part of a decadelong study into the world’s deepest fish populations that was carried out by the University of Western Australia and the Tokyo University of Marine Science and Technology. “We have spent over 15 years researching these deep snailfish; there is so much more to them than simply the depth, but the maximum depth they can survive is truly astonishing,” Alan Jamieson, the director of the Minderoo-UWA Deep Sea Research Centre, said in Days after the fish were filmed, the team collected two snailfish ( Pseudoliparis belyaevi) in traps set 26,319 feet (8,022 meters) deep in the Izu-Ogasawara Trench. Snailfish caught at depths of around 8,000 meters in a trench off Japan in the Pacific Ocean. University of Western Australia and Japan In remarkable footage released Sunday, a number of translucent, scaleless fish with winglike fins and eel-like tails can be seen swimming in a black abyss, illuminated by a spotlight cast from a baited camera. It wasn't immediately clear how big the fish were. “In other trenches such as the Mariana Trench, we were finding them at increasingly deeper depths just creeping...

Resting at a depth equivalent to about 17 Empire State Buildings stacked top to bottom, the Factorian Deep was discovered in 2019 by American explorer and entrepreneur Victor Vescovo, as part of his Five Deeps Expedition to map the deepest points of the world's five oceans. Vescovo personally piloted a submersible named "Limiting Factor" (for which the Factorian Deep was named) to the bottom of the Atlantic Ocean's South Sandwich Trench – an undersea canyon that spans roughly 600 miles (965 kilometers) of seafloor between South America and Antarctica. The trench crosses the 60th parallel south, an invisible circle of latitude that is 60 degrees south of the equator, separating the Atlantic and Southern oceans. Vescovo's expedition mapped the entire length of the South Sandwich Trench for the first time ever, uncovering the Southern Ocean's new deepest point just south of the 60th parallel. And now, the Factorian Deep has been documented for the first time on a seafloor map. In a new study, published June 7 in the journal Scientific Data, an international team of researchers included the Factorian Deep in a sprawling new map of the Southern Ocean's undersea mountains, canyons and plateaus. The massive map is a joint effort of the International Bathymetric Chart of the Southern Ocean (IBCSO), which began charting the Southern Ocean in 2013, and the Nippon Foundation-GEBCO Seabed 2030 Project, which aims to map the entire global seafloor by 2030. The new map draws from more t...

As part of the Data published in Geoscience Data Journal shows the deepest point of the Indian Ocean at 7187m, within the Java Trench, and the deepest point of the Southern Ocean at 7432m, within the South Sandwich Trench. Prior to the Until now, there had been a lack of high-resolution data available for the Indian Ocean and Southern Ocean and there was considerable doubt as to the Located just north of the Antarctic continent, the South Sandwich Trench spans both the Southern and Atlantic oceans. It had not been thoroughly explored prior to the FDE mission and is the only subzero hadal zone (deeper than 6000m) in the world. The FDE survey produced the most accurate mapping of the South Sandwich Trench to date, using a modern multibeam sonar system. The new survey has shown that the deepest point of the trench is Meteor Deep at 8265m and is located within the waters of the Atlantic Ocean. The recently named Factorian Deep, located at the southern end of the trench, is 7432m deep...
