Sunlight Zone Layers

The Many Layers of the Ocean
With the ocean taking up over 70 percent of Earth it has been broken down to layers in order to classify the ocean depth and the components in each section that vary by location. The components in each layer are caused by many factors including sunlight, temperatures, weather, and many other factors that can vary from location.
The first layer is the Sunlight Zone which is located at the depth of approximately 200 meters. The Sunlight Zone is hit with the most amount of light from the sun which causes temperature changes based on location and seasons. (Layers of the Ocean, 2008) With high exposure to winds which moves the heat in the water and cause currents and waves which is strongest at the surface (Ocean's Vertical Structure Background, n.d.) of the Sunlight Zone. At the base of the Sunlight Zone is the start of the thermocline region at which the temperature dramatically decreases. (Layers of the Ocean, 2008)
The next layer is the Mesopelagic Zone, also known as the twilight zone, which is …show more content…

The Bathypelagic Zone has a constant temperature of 39 degree Fahrenheit and ranges from 1,000 to 4,000 meters, and has no sunlight that is able to penetrate to this depth which is why it is also known at the midnight zone. There is light that comes from the animals that live at this depth. The Abyssopelagic Zone it completely black and it at freezing temperatures. This zone ranges from 4,000 to 6,000 meters and account for almost two-thirds of the ocean floor. Very little marine life is able to live at this depth due to the weight of the water above them. The Hadalpelagic Zone is the deepest zone in the ocean and ranges from 6,000 to 10,911 meters, which is the depth of the Mariana Trench. There are some small single-celled organisms that are able to survive at this depth. (Layers of the Ocean,

Hastings Point Lab Report

1610 Words | 7 Pages

This adaptation is to retain moisture using a special structure – the operculum – which can be sealed when the snail is not eating to retain moisture within the shell. This is used especially between the high tides, as water only reaches this high zone at these times. Another factor associated with the supralittoral zone is harsh wind conditions, which was observed at Hastings Point where the temperature indicated a 12% increase in average temperature between the littoral and supralittoral zones. The black nerites adapted behaviourally to survive these conditions. To do this,

Factors Affecting Nashville's Physiographic Regions

767 Words | 4 Pages

On a sunny day, the land absorbs heat from the sun more quickly than the water does. The air over the land becomes warmer as some of this absorbed heat is radiated back into the air. The warmer air begins to rise, and the cooler air over the water moves in to take its place. At nighttime when the sun goes down, the land cools off quickly, but the water does not. The water radiates some of its stored heat into the air, and this warmed air begins to rise.

Robert Ballard's Accomplishments

2006 Words | 9 Pages

Mapping out the ocean floor enabled to Ballard to observe where he should travel to in order for his trip underwater to be safe. He was able to map out the obstacles that could be in his way and disrupt his explorations. With the investigation of unknown species, Ballard was able to observe their lifestyles and extracted information that could be essential to his research besides the abandoned shipwrecks. “On one of his most famous expeditions, Dr. Ballard and a team of scientists traveled to the Galapagos Islands in 1977 and discovered hot springs on the ocean floor called hydrothermal vents” (Education through Exploration).

The first one that the beluga will pass through is called Epipelagic Zone or the "Sun Light Zone". When a beluga dies it gives nutrients and food to all the animals and life that is there. The second layer it goes through is called the Mesopelagic Zone or the "Twilight Zone". Many of the beluga isn 't left by then but the nutrients of other fish and the beluga still continues to float to the next layer of the ocean. The third layer of the ocean that the beluga falls through is called the Bathypelagic Zone also known as the "Midnight Zone".

The Abyssal Plains In The Atlantic And Indian Ocean

90 Words | 1 Pages

Abyssal plains are generally flat areas of the ocean basin, that are usually found at depths of 13,000-16,000 ft. Abyssal plains are believed to be flat because they are overlaid with sediments that have been drained off the surface of continents for thousands of years. On the abyssal plains, the sediment layers have hidden any deviation that may exist in the rock of the ocean floor under them. In the Atlantic and Indian Oceans the abyssal plains are usually bigger in length compare to those found in the Pacific Ocean.

Hydrothermal Vent Habitat

1824 Words | 8 Pages

Mid-ocean ridges are sub-surfaced mountain ranges located at the boundaries between the tectonic plates that make up the Earth’s crust (van Dover, 2000; Tivey, 2007; Martin et al., 2008). As the plates are pulled apart by tectonic forces, hot soft rock from the deep Earth emerges to fill the fissure. As the generated ocean crust laterally moves away from the spreading-axis, the age of the crust and the depth of the sediment cover increase systematically (van Dover, 2000). Therefore, different types of hydrothermal vents occur at different areas of the ultramafic sea floor. The simplest of these are the columnar sulfide chimneys at the East Pacific Rise (EPR).

The documentary “Shallow Seas” provided me with a lot of detailed information about the marine life that appears in the shallow seas. Shallow seas are near the equator. Therefore, these seas are comprised of warm tropical waters and contain the majority of marine life, such as biomass and fisheries. The film educated me about the unknown marine life that appears in the shallow seas.

Ocean V. Space Exploration The ocean covers more than 70% of the Earth, yet we’ve explored only around 5% of it. This means there is so much more to explore in the ocean. The one reason we haven’t explored as much of the ocean is because of space. Space is wildly more popular, and has proven its worth with many advancements.

Why Did James Weddell Sail So Far South?

753 Words | 4 Pages

Introduction On February 20, 1823, the British sailor James Weddell (1787-1834) and his crew reached 74,15 degrees south, the furthest south any men had ever been in the history of the world until then. In doing so, they had sailed deep into an unknown sea. At that moment, Weddell decided to turn back, despite having an open ocean before him. To this day, this feat is still the reason why James Weddell is remembered; because the sea he discovered is nowadays called the Weddell Sea.
