Mariana Trench - The Life Challenges at the Deepest Sea Floor (10KM Below Water Level)


Mariana Trench: The Life Challenges at the Deepest Sea Floor 10KM Below Water Level HD Documentary

The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 metres (36,037 ft) (± 25 metres [82 ft]) (6.825 miles) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.However, some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft). If Mount Everest were placed into the trench at this point, its peak would still be under water by more than two kilometres (1.2 mi).

Mariana Trench: Record-breaking journey to the bottom of the ocean - BBC News

An American explorer has descended nearly 11km (seven miles) to the deepest place in the ocean - the Mariana Trench in the Pacific.

Victor Vescovo spent four hours exploring the bottom of the trench with the risk of his submersible imploding if anything were to go wrong.

The dive was later verified to be 10,972m and Victor became the first person to reach the deepest part of the Pacific Ocean.

The depths of the ocean are one of the most understudied areas in the world. Unfortunately, even in the 21st century, we have not been able to study the seabed in detail. It is located, by the way, thousands of meters below the surface of the water. However, this is where the most interesting and terrifying creatures on the planet live. In today's video we are gonna talk about the most amazing living creatures in the depths of the sea. Tell us in the comments, which of these animals would you like to see live. If you have the courage, of course.

Mariana Trench | Challenger Deep | Deepest Part Of The Planet Earth | AtomsTalk

The Challenger Deep in the Mariana Trench is the deepest known point in Earth's oceans. It is a famous place much-known for its varied sea lives and depth as well as the wonder of the nature below the surface of the earth.

If you cut the famous mountain pick of Himalayas, Mount Everest, off at the sea level and place the same at the marine bottom here, there will be still a couple of miles of water over the top of it. This trench is positioned in the parts of the western Pacific Ocean. It lies to the east of the Philippines. The Mariana Trench is a curved shaped blemish in Earth’s shell that measures more than 1,500 miles long and 43 miles wide on average. In this video let us see a few things including expeditions, difficulties and Mariana trench creatures.

MBARI's Top 10 deep-sea animals

The deep sea—Earth's largest habitat—is home to a host of magical and mysterious animals. As we help our education and conservation partners at the Monterey Bay Aquarium prepare for the exhibit Into the Deep: Exploring Our Undiscovered Ocean, launching in 2022, they were curious to know which denizens of the deep are our favorites? With that question in mind, we gathered five of MBARI’s finest deep-sea biologists—Shannon Johnson, Kakani Katija, George Matsumoto, Bruce Robison, and Susan von Thun—and came up with a list of ten favorites. You might be surprised to see what made our list and what makes these creatures so lovable.

For more than three decades, MBARI researchers have been exploring the deep ocean with remotely operated vehicles, discovering fascinating ways that life in the deep sea has evolved to thrive in this dark, cold world. Our ocean is vast and full of things yet unseen. Every time we set out on an expedition, we are amazed by new observations and we are excited to share ten of those discoveries with you!

Great Animation Shows How Deep Humans Dug Into The Earth

Courtesy of Tech Insider --- Extreme Journey to the center of the Earth - Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples. Most of the technology used for drilling come from advances in the oil and gas industry. Scientific drilling is carried out on land by the International Continental Scientific Drilling Program (ICDP) and at sea by the Integrated Ocean Drilling Program (IODP). Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here.

Like probes sent into outer space, scientific drilling is a technology used to obtain samples from places that people cannot reach. Human beings have descended as deep as 2,080 m (6,822 ft) in Voronya Cave, the world's deepest known cave, located in the Caucasus mountains of the country of Georgia. Gold miners in South Africa regularly go deeper than 3,400 m, but no human has ever descended to greater depths than this below the Earth's solid surface. As depth increases into the Earth, temperature and pressure rise. Temperatures in the crust increase about 15°C per kilometer, making it impossible for humans to exist at depths greater than several kilometers, even if it was somehow possible to keep shafts open in spite of the tremendous pressure.

Scientific drilling is interdisciplinary and international in scope. Individual scientists cannot generally undertake scientific drilling projects alone. Teamwork between scientists, engineers, and administrators is often required for success in planning and in carrying out a drilling project, analyzing the samples, and interpreting and publishing the results in scientific journals.

Humans have reached the moon and are planning to return samples from Mars, but when it comes to exploring the land deep beneath our feet, we have only scratched the surface of our planet.
This may be about to change with a $1 billion mission to drill 6 km (3.7 miles) beneath the seafloor to reach the Earth's mantle -- a 3000 km-thick layer of slowly deforming rock between the crust and the core which makes up the majority of our planet -- and bring back the first ever fresh samples.
It could help answer some of our biggest questions about the origins and evolution of Earth itself, with almost all of the sea floor and continents that make up the Earth´s surface originating from the mantle.
Geologists involved in the project are already comparing it to the Apollo Moon missions in terms of the value of the samples it could yield.
However, in order to reach those samples, the team of international scientists must first find a way to grind their way through ultra-hard rocks with 10 km-long (6.2 miles) drill pipes -- a technical challenge that one of the project co-leaders Damon Teagle, from the UK's University of Southampton calls, the most challenging endeavor in the history of Earth science.
'A ship flying in space:' Earth seen through the eyes of an astronaut
Their task will be all the more difficult for being conducted out in the middle of the ocean. It is here that the Earth´s crust is at its thinnest at around 6 km compared to as much as 60 km (37.3 miles) on land.
Drilling all the way to the mantle would also give geologists a look at what they call the Mohorovičić discontinuity, or Moho, for short. Above this mysterious zone, named for the Croatian seismologist who discovered it in 1909, seismic waves travel at around 4.3 miles per second, a rate consistent with those waves traveling through basalt, or cooled lava. Below the Moho, the waves rip along at around 5 miles per second, similar to the rate they travel through a silica-poor type of igneous rock called peridotite. The Moho typically lies between 3 to 6 miles below the ocean floor and anywhere between 12 to 56 miles beneath the continents.

This zone has long been considered the crust-mantle boundary, where material gradually cools and sticks to the overlying crust. But some lab studies suggest it’s possible that the Moho represents the zone where water seeping down from the overlying crust reacts with mantle peridotites to create a type of mineral called serpentine. This possibility is exciting, Dick and MacLeod suggest. The geochemical reactions that generate serpentine also produce hydrogen, which can then react with seawater to produce methane, a source of energy for some types of bacteria. Or, the researchers note, the Moho could be something else entirely unknown to science.

Mariana Trench (Marianas Trench): The Deepest Place in The Earth

Mariana Trench is the deepest place on earth. The Marianas Trench is full of mysteries. Many of the things are unknown to us. Many scientist have tried to descent on the top of the Mariana trench but, only 12 people have able to do so. The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 metres (36,037 ft) (± 25 metres [82 ft]) (6.825 miles) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. However, some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft). If Mount Everest were placed into the trench at this point, its peak would still be underwater by more than two kilometres (1.2 mi).
At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).

Many people have tried to explore this place. Only 12 people have successfully able to do that. Find below the details of that person.

Mystery Behind Mariana Trench || Most deepest area of the world

The Mariana Trench or Marianas Trench is located in the western Pacific Oceanapproximately 200 kilometres (124 mi) east of the Mariana Islands, and has the deepest natural point in the world. It is a crescent-shaped trough in the Earth's crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide. The maximum known depth is 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.However, some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft).[3] For comparison: if Mount Everest were dropped into the trench at this point, its peak would still be over two kilometres (1.2 mi) under water.

At the bottom of the trench the water columnabove exerts a pressure of 1,086 bars (15,750 psi), more than 1,000 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%, so that 95.27 litres (20.96 imp gal; 25.17 US gal) of water under the pressure of the Challenger Deep would contain the same mass as 100 litres (22 imp gal; 26 US gal) at the surface. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).

The trench is not the part of the seafloor closest to the centre of the Earth. This is because the Earth is not a perfect sphere; its radius is about 25 kilometres (16 mi) smaller at the poles than at the equator. As a result, parts of the Arctic Ocean seabed are at least 13 kilometres (8.1 mi) closer to the Earth's centre than the Challenger Deep seafloor.

In 2009, the Marianas Trench was established as a United States National Monument.

Xenophyophores have been found in the trench by Scripps Institution of Oceanographyresearchers at a record depth of 10.6 kilometres (6.6 mi) below the sea surface. On 17 March 2013, researchers from the Scottish Association for Marine Science reported data that suggested microbial life forms thrive within the trench.
