Characteristics Of The Ocean Zones From The Deep Sea

The euphotic zone or more commonly known as the sunlit zone is home to over 90% of all marine life, this includes plankton, sea horses, stingrays, and many more beautiful aquatic animals. The euphoric zone extends 600 feet below the surface because this is as far as the sun light will go below the surface. The sunlight that penetrates the water is bright enough to support photosynthesis, making it the only zone where plant life can grow. This zone is the smallest of all three ocean zones. The second largest is the disphotic zone

The Tidal zones consist of splash zone, high water neap tide, low water neap tide, high water spring tide, low water spring tide, mid tide level and the splash zone and sub littoral zone. All of these tidal zones can be determined by which indicator organisms/animals are living there. For an example the splash zone is the highest of all zones and the organisms that are generally living there are noddiwinkles. If you spot a lot of honeycomb barnacles and blue-grey periwinkle’s then you are most likely in the high water tide zone and water only covers this zone at high tide. White tube worms are indictor organism the mid tide level zone and is covered by water for half of the day. There’s also the low tide zone which is engulfed in water for the majority of the day expect at low tide, you can determine this zone by finding indicator organisms such as sea squirts. The final tidal zone is the sub literal zone and this is always under water the indictor organism’s living here are brown tubeworms and striped girdled chiton.

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

Scientist in order to measure the depth of the ocean use “Bomb Sounding” this is where they throw TNT into trenches and from the echo that it gives the scientist than approximate its depth. “Recent expeditions such as the HADES project in the Pacific suggest that fish are not found below 27,560 feet. But the hadal zone extends to 36,000 feet”, (Cock-Starkey 9). The development of the “DeepSea Challenger” allowed the ability for scientist to travel down the trench to collect rocks, sediments,and biological samples. Scientist from Scripps Institute Oceanography, University of Hawai’i, and Jet Propulsion Laboratory all joined in into the DeepSea Challenger setting their research on marine biology, microbiology, astrobiology, marine geology and geophysics. Living in the deepest part of ocean surfaced thoughts of marine life being non-existent because of the lethal conditions it has , but past findings of marine life as deep as 27,560 feet shook scientist. Marine adaptation has grown because of the frequent findings of marine life such as the following: Frilled Shark (5,000 ft), Giant Spider Crab (estimate 1,000 ft), Atlantic Wolffish Pair (1,600 ft), Fangtooth Fish (16,500 ft), Six-Gill Shark (8,200 ft) and etc. All these deep sea creatures have adapted to low oxygen levels and the lightless depth of the

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

In ocean studies, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone.

Each of these layers decreases in sunlight and temperature as depth increases. On average, sunlight fades away in seawater at approximately 200 meters deep. With no sunlight to heat the water, temperatures plummet at depth, leaving the water at Challenger Deep just a few degrees above freezing. On top of having no sunlight and near freezing conditions, the deep sea also possesses pressure unlike anywhere else on earth. Opposite to climbing a mountain and experiencing a decrease in pressure, in the ocean pressure increases the deeper one goes, due to the weight of the water above. At Challenger Deep, the weight of nearly 7 miles of water above causes the pressure to reach 8 tons per square inch (About the Mariana). In spite of these brutal conditions, life still has found a way to thrive at these great

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 marine deep biome starts at about 100 feet deep in the ocean and ends at around 5000 feet. The location is slightly in between the euphotic and disphotic ocean zones. Because of the little light that enters the disphotic zone, the organisms there, rely on the zone above for food. In the upper part of the marine deep biome, photosynthesis occurs, allowing producers to thrive and eventually be eaten by lower located organisms. Some examples of producers that can be grown by process of photosynthesis are phytoplankton, seaweed, and algae. Without the sunlight, there would be no way for deeper sea life to survive. A couple of those lower organisms are shrimp, mollusks, and zooplankton; which are all herbivores. Carnivores, which feast on these

have Previously watched many ocean documentaries. One I found particularly interesting was David Attenburgs bio luminescent documentary, (I'll try to provide a link to it) This one, is also by him and I'm seeing some repeated scenes. In our course material it wasn't mentioned much, as far as the textbook goes. The creatures of the deep have large eyes and strong large jaws. I was surprised to hear how large the hairy angler was, I had always assumed angler fish where small, about the size of a prawn. I was surprised at there being walking sea urchins, they look very strange. The mushroom coral looks to be a coral that could be used to repopulate the planet in case the coral there went extinct. I find it pretty amazing that there are such large

In the temperate oceans, characteristic stratification of the deep ocean layer and the surface of the ocean break down, through the seasonal change of fall into winter. The layers of the ocean mix and upwelling is performed. The stratification of the surface ocean re-stabilizes, when the spring season heads into summer. Phytoplankton blooms as a conclusion of this.

The mid night zone should be explored by scientist to learn more about the ocean's unusual area. I think this because the vast mid night zone makes up 90 percent of our ocean. In this zone, the mid night zone, there are an abundance of hydro thermal vents that we are not able to go near. (hyrdo Thermal Vents-an opening in the sea floor out of which heated mineral-rich water flows.)

The plants down at the bottom of the Mariana Trench don’t get sunlight so they use the minerals from the sand to grow. The people that made it down to the bottom of the mariana trench were brave and ready to do anything. They were brave enough to kill a bear without any weapons. They had ice in their veins because

Another abiotic factor that helps the formations of different zones would be the tidal movement (aerial exposure) effecting the sea life shore community. The tidal zones we found at Siren’s Rocks are the sublittoral zone, low tide, mid tide, high tide and supralittoral zone. These are all on the data recorded by us at the rocky shore we researched.
