Researchers Find And Film World’s Deepest Fish In The Mariana Trench

Dec 31, 2014

An underwater voyage, into the Mariana Trench, has found an unidentified species of fish more than 5 miles deep, which is a new record for the deepest fish ever discovered and filmed.

The Mariana Trench is the deepest point on Earth, which is located in the Western Pacific near Guam. It is made up of some of the oldest seabed in the world — over 180 million years old. It was formed by lava from underwater volcanic action. As lava cooled, aged and spread it became increasingly dense and settled. Many attempts have been made to reach to its deepest point, the Challenger Deep. According to the National Oceanic and Atmospheric Association, the water pressure at this deepest part of the trench is equivalent to the collective weight of 50 jumbo jets.

Marine biologists and scientists recently descended towards the Mariana Trench that gave up a creature living in this deepest point on Earth – a snail-fish. The discovery was made during a marine voyage on board the research vessel Falkor of the Schmidt Ocean Institute.

This Hadal Ecosystem Studies (HADES) expedition was led by co-chief scientists Jeff Drazen and Patty Fryer of the University of Hawaii. The researchers sent five deep sea vehicle systems called the Hadal landers for a total of 92 times at specifically targeted depths from 5000 meters to 10,600 meters. The Hadal lander is equipped with a variety of scientific instruments, high resolution cameras and array of small baited funnel traps, which are used to lure and trap small animals.

  • wing-like fins, eel-like tail, and a head that resembles that of a dog

    Platypus of the extreme deep?

    Mariana Trench, least explored

    Perhaps terra firma folk, looking to relocate, will become aquanauts before astronauts; then again, why f**k up one of the last few places unspoiled by humans? Also – how, if at all, do the deep sea critters initially respond to the lander’s light?

  • According to the National Oceanic and Atmospheric Association, the

    collective weight of 50 jumbo jets.

    I very much doubt NOAA said this. It is meaningless and indicative of sloppy journalism. Pressure is force (not weight) per unit area. The “weight of 50 jumbo jets?” Over what area? Over an airport maybe? Sounds like LAX on a normal day, and not a bit like the bottom of the Mariana’s Trench.

    FWITW, the pressure at the bottom of the Mariana’s Trench is 108.6 mega pascals in SI units, 15,750 psi in Imperial units, or if you insist on jumbo jets, and not allowing for the reduction in force due to their being immersed in a denser medium than air, it is very roughly 50 fully loaded 747-400’s stacked on top of each other in a 4′ x 4′ square.

    PS to the above, just what was god thinking, creating fish at the bottom of the deepest part of the ocean? Somewhere where there was no chance of finding them until Adam’s descendents had become smart enough to realize that god himself was nowhere to be found, not even down there.

    If NOAA did say that, you can bet they said it to explain it to a dumb journalist, and would have included a (now missing) unit of area to indicate the pressure!

  • ” FWITW, the pressure at the bottom of the Mariana’s Trench is 108.6 mega pascals in SI units, 15,750 psi in Imperial units ”

    108.6 mega pascals (10^6 pascals/1 mega pascal)(1 atmosphere/101,325 pascals)

    = 1071.8 atmospheres

    Now I can appreciate the pressure!

    It’s from their website. national ocean service: Pressure increases with ocean depth

    Take it up with them. nos.info@noaa.gov
