The Mariana Trench- Science Report

9. Oceanward of the oceanic trench, the ocean bottom first rises and then levels off to a depth of approximately 3900 m, making the deepest part of the ocean trench about [(1400)(2400)(3500)] m below the bottom of the abyssal plain ocean bottom west of the trench.

In the article “What’s at the Bottom of the Ocean?” authored by Samantha Larson, it states that there is more to see on the ocean floor than meets the eye. David Gruber, the main oceanographer in the ocean exploration team, has discovered hundreds of unknown species and has even helped with breakthroughs in medical research. “The deep sea is a beautiful and foreign place, with many different creatures and geological structures,” Gruber expressed. When he was traveling underwater in the South Pacific, he witnessed tens of thousands of tiny flashlight fish swimming in 20 foot waters. He also discovered that these flashlight fish use biofluorescence to communicate with each other by absorbing blue light and turning

It all started when the shipping container we were riding in from the United States to England fell overboard. It plummeted into the ocean floor and busted open when it crashed into the flattest part of the ocean. We floated up through the three ocean zones to the surface of the ocean. On our journey from the Midnight zone to the Sunlight zone, we saw fascinating ocean creatures and various plants. Starting from the Midnight zone we noticed fewer plants and animals than the Sunlight zone due to its cold temperatures. Most of the animals looked like as if they were to belong here and there was absolutely no sign of plants. But, we also noticed fewer creatures which adopted very well to these cold and freezing temperatures. Most of these temperatures happen in the deep sea trenches, Abyssal plain, and the Continental rise.

Has it ever occurred to you that there is another world among us? Beneath the deep blue sea is a vast landscape with plants and animals abundant. These animals are constantly forced to adapt to survive, showing just how strong and resilient they are. Three of these, however, stand out from the rest with features that allow them to survive in the harshest conditions.

The deepest depths of the ocean are unfathomable, no one knows what creatures lurk down there.

An entire new world, different from our own exists beneath the surface of our oceans. This life is full of color, shapes, sizes, wonder, and even darkness. Much of this life has yet to be explored but we still know that beneath the waves exist the most beautiful creatures and the most bizarre. Magical areas such as the coral reef and mysterious areas such as the depths of the ocean are homes to over 700,000 species that live in the ocean. This includes the eighty percent of the ocean that has yet to be explored. Even though there may be separate oceans on this planet, they are still interconnected by a body of salt water. No area of the ocean is the same, which brings us to the wonderful fact that so many different species are able to flourish

The sea is often perceived as a whole other world that science sometimes struggle to explain, its depths

In this episode of the BBC documentary series, “The Blue Planet: Open Ocean,” we were able to explore the abundance and complications of the open ocean, the pelagic zone. Over 60% of our planet is covered by the ocean, yet the deep sea is largely still unknown. We know more about the moon than what we know about the deep ocean. The temperature and the level of sunlight decrease as the depth increases. The ocean may appear uniform from the surface, but there is several layers to the ocean. The pelagic zone contains the most area of the open ocean. The zone includes everything except for the coastal waters and the sea floor. However, even within this area, there are variation since some part is lifeless with very little amount of organisms and

The Sublittoral is the region of the ocean below the low tide limit and extends all the way to the edge of the continental shelf. This zone is submerged permanently despite the turn of the tides and the intra/interspecific competition for space is extreme. Organisms in this region rarely experience intense sun or air exposure and organisms such as blue

Within explicit texts, "Into the Deep," by Spencer Kayden moreover including, "What's Down There," by Mackenzie Carro, there is a ubiquitous theme concerning the correspondence between humankind and the subterrene ocean. It investigates how we are achieving to find life submerged in the sea using modern technology. It explains that we continue to discover multiple forms of life underneath the shores using research and submersibles. Because of this detail and additional ideas pointed out in both pieces, the two are more comparable than expected.

often will people think of a nautilus, an organism that is a distant cousin of cuttlefish and squid. These organisms have been dubbed "living fossils" and have been on earth for about 500 million years. The nautilus tends to in front of coral reefs, deep in the ocean. The long existence of the nautilus has allowed its mesmerizing spiral shell to be embedded in some rocks and has become a part of the fossil record.

The off-shore marine environment changes intensively with the change in the ocean depth. There are three distinctive zones that can be classified along the depth which is the Epipelagic which extends from the sea surface to a depth of 200 meters, the mesopelagic which extends from a depth of 200 meters to a depth of a 1000 meters and then the Deep sea which extends from a depth of a 1000 meters to the sea floor (Castro & Huber, 2010). The Deep sea can then be divided into a further three zones (Figure 01) Bathypelagic which extends from a depth of a 1000 meters to 4000 meters, Abyssopelagic which extends from a depth of 4000 meters to 6000 meters and then the Hadopelagic which extends which extends from a depth of 6000 meters to the sea floor (Castro & Huber, 2010).

ocean is made up of different layers of varying densities and chemical compositions. During the

The large, beautiful bodies of water are home to an infinite number of strange creatures and bewildering phenomena. Oceans make up about three-fifths of the earth and yet we have little idea about what lies in those darkened depths. There are many mysteries of the oceans that still have no explanation. To start with, scattered around oceans there trenches, incidentally all of them are approximately seven miles deep.

For many years humans have struggled to discover the deepest parts of the ocean and have also struggled with discovering space. We could not go really deep into the ocean, because humans can not withstand the pressure that the ocean produces. But now there is a robot that can reach the ocean floor called “The Benthic Rover”. With that new robot, scientist will be able to record how changes on the surface of the ocean will impact the marine animals below. “What is special about the rover is that we will be able to stay in the deep parts of the ocean for a really long time collecting seasonal changes data” (Engineer Alana Sherman). With Benthic Rover,
