The seem, we know more about outer space than we do about the deep oceans The Mariana, or Marianas, Trench is a deep-sea trench in the floor of the western North Pacific Ocean.It is located about 124 miles (200 kilometers) east of the Mariana Islands.It is the deepest such trench known on Earth and thus the deepest known point in the ocean. their numbers are so vast that scientists are using the crab clusters meters (approx. Recent studies indicate that by trapping particles from the water, xenophyophores can concentrate high levels of lead, uranium and mercury and are thus likely highly resistant to large doses of heavy metals. Stomata: A tiny pore in a leaf that closes and opens and exchanges gas. As you'd imagine, not many animals you know of live without sunlight. In this study, unexpected microbial ecosystems associated with the hadal trench water were discovered down to a 10,257-m water depth in the Challenger Deep of the Mariana Trench, which is the deepest ocean on Earth. Learn more as the Angler Fish (see illustration),  so called because it uses On average, it has the width of 43 miles or 69 kilometers. In the abyssal zone light does not reach, therefore the entire trench is in complete darkness. Read here to learn more about the Mariana Trench. In 1860, Charles Wyville Thomson, wanted to make a boat trip to conduct oceanographic studies. Until now, scientists knew more about Mars than the … A snailfish collected from the Kermadec Trench in the southwest Pacific Ocean. The deepest part of the ocean is called the abyssal zone. It stretches for more than 1,580 miles (2,540 km) with a mean width of 43 miles (69 km) and is part of the western Pacific system of oceanic trenches coinciding with subduction zones. Following the first descent was the Japanese Kaiko in 1996 and Nereus in 2009. In the abyssal zone light does not reach, therefore the entire trench is in complete darkness. Located in the Pacific Ocean, the Mariana Trench forms a large crescent-shaped depression in the sea bed in the vicinity of the Mariana Islands, after which the trench is named. extremes by having different proteins which are adapted for life under It seems impossible that any life — animal, plant, or even microbial — could live or flourish here, and yet the Mariana Trench is home to a large variety of rare and unusual wildlife. It's a geological feature so massive, so vast and so imposing that it makes Mount Everest look like a mole hill by comparison.

Since these creatures seldom migrate and are slow to creatures from the deep show an incredible At areas like the Mariana Trench (or the Marianas Trench; both spellings are commonly found) the water temperature ranges from 34-39 degrees F (1-4 degrees C).-The Editors (Photo credit: Paul Yancey) The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world’s oceans, including the deepest spot of all: the 36,000-foot-deep Mariana Trench in the northwest Pacific Ocean. Like other oceanic trenches, the Mariana Trench has been proposed as a site for nuclear waste disposal in 1972, in the hope that tectonic plate subduction occurring at the site might eventually push the nuclear waste deep into the Earth's mantle, the second layer of the Earth. 12, 2019 — Research that reveals what lies at the bottom of the deepest part of the ocean -- the Mariana Trench. Pelagic On December 21, 1872, he sailed on the HMS Challenger, a modified warship for the voyage carrying everything from fishing gear to microscopes. It also contains the deepest known point in any ocean. The reason why no living plants exist there is because there is extremely little to no sunlight that is required for photosynthesis. Examples of fibers from trench amphipods (Lauren Brooks / … Large single-celled lifeforms, called xenophyophores, live in … a bioluminescent (life light) protrusion to attract its prey. Another interesting characteristic of these deep sea creatures is The thermocline varies in thickness from about 1,000 feet to 3,000 feet. After some thought you might have asked yourself a serious question. Here we present a sonar generated compilation image. The Mariana Trench is the deepest known submarine trench.It is also the deepest known location on Earth itself. Temperatures hover right around freezing. Earthquakes also trigger mudslides that carry debris down. fish, and so on. Fahrenheit), and the highest any animal can withstand  is 50° Also, the deeper you go in the ocean the colder it gets. Below this point water cools more slowly. and highly pressurized; its floor features hydrothermal (hot water ) vents formed by spreading If you want to explore the depths of the ocean, you may want to go to the deepest part: the Mariana Trench. Challenger Deep in the Mariana Trench is very cold, makes it the largest habitat for creatures on the planet Earth. The highest temperature bacteria can withstand is 113° Celsius (235°  The  temperature around the vents known as biogenous "ooze". Garbage from all over and even lost fishing nets can sink their way down in to the dark. Four descents into the Mariana Trench have been completed. When surface plants die, their decomposing contents fall until they hit the bottom of the ocean, or any floor-like area for it to decompose. I'm sure you can imagine how cold it … deepest part of the ocean is called the abyssal zone. Root: Roots hold the plant in the ground and take up water and minerals. I'm sure you can imagine how cold it gets, around 34 degrees Fahrenheit (1 C).

The Also, as our technology advances there might even be  countries debating on who can get to collect it's resources;  this could include precious metals, oil, and unknown discoveries. hydrothermal vents is the Bythograea thermydron, of "Vent Crab" - consumed by other microorganisms, which are in turn, consumed by the A few animals found in the trench include Angler fish,  Tubeworms, Sea Cucumbers, Snailfish, Jelly Fish, Amphipods, Forams, and Sea Dragons. slightly basic. other minerals which are consumed by the barophilic bacteria which are then The water in the trench is very dark.
