The Epipelagic Zone, also known as the ‘Sunlight Zone‘ is the region of the ocean that sits on the continental shelf. It extends from the surface down to 200 m.
What is the epipelagic zone also known as?
Epipelagic Zone. This surface layer is also called the sunlight zone and extends from the surface to 200 meters (660 feet). It is in this zone that most of the visible light exists.
Why is it called the epipelagic zone?
The epipelagic zone.
The upper part of the ocean where algae can grow is termed the “epipelagic” zone, The prefix “epi” means “upper” and the term “pelagic” means “open-ocean” or “ocean”. In a clear ocean, it may reach a depth of 600 feet.
What is another name for the photic zone?
Photic Zone is the top layer, nearest the surface of the ocean and is also called the sunlight layer.
Is the epipelagic zone the same as the photic zone?
…the neritic and oceanic waters—the epipelagic zone—is where photosynthesis occurs; it is roughly equivalent to the photic zone.
What does epipelagic mean?
: of, relating to, or constituting the part of the oceanic zone into which enough light penetrates for photosynthesis.
What are the 3 zones of the ocean?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
Which ocean zone is called the deep-sea?
Hadalpelagic. The hadalpelagic is the very deepest part of the ocean that includes the ocean trenches. It extends from 19,700 feet (6,000 meters) to the very bottom of the Mariana Trench at 36,070 feet (10,994 meters). Very little is known about the creatures that live at such depths.
What ocean zone is the Titanic in?
The Titanic lies at 3,800 meters or about 12,500 feet. This area of the ocean is known as the Bathyal zone. The average temperature is 39° F. The pressure at this depth is 5,850 pounds per square inch.
What are the 4 zones of the ocean?
There are four ocean zones: the Sunlight zone, the Twilight zone, the Midnight zone, and the Abyssal zone.
What is another name for the sunlit zone of the ocean?
From Sunlight to Darkness
The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.
What is in the abyssal zone?
The seafloor and water column from 3,000 to 6,500 meters (9,842 to 21,325 feet) depth is known as the abyssal zone, or the abyss. Sunlight doesn’t penetrate to these depths, so the waters here are extremely dark, and the animals that live here often use bioluminescence to communicate.
What is photic and aphotic zone?
Zones Based on Depth of Water
Scientists refer to the vertical extent of ocean water as the water column. Two main zones based on depth of water are the photic zone and aphotic zone. The photic zone is the top 200 meters of water. The aphotic zone is water deeper than 200 meters.
Which zone is equal in depth to photic zone?
The photic zone extends from the surface of the ocean to the depth where light is too dim for photosynthesis, on average 200 meters deep. This is similar to the epipelagic zone and sometimes the two are considered equivalent.
What is the name of the zone of the ocean where plankton live?
Planktonic aquatic organisms such as phytoplankton, are shallow water creatures; they are restricted to the photic zone in oceans because growth is totally dependent upon photosynthesis.
What is another name for the mesopelagic zone?
The mesopelagic zone extends from around 200 to 1000 m depth (see Fig. 1.9) and is sometimes known as the twilight zone, because sunlight can still be detected here at low levels.
How much light is in the epipelagic zone?
From the base of the epipelagic zone to a depth of about 850 meters, there is still enough light for a human to see. The second zone between 200 meters and 1,000 meters is known as the “twilight zone”. Some light penetrates as far as 1000 meters down into the ocean.
What is in the sunlight zone?
The sunlight zone is the area between 0m and 200m beneath the surface of the sea and is home to endless quantities of life. The sunlight zone is where microscopic organisms are able to convert the Sun’s energy through photosynthesis.
What is the 3 major zone?
Earth’s climate can be divided into three major zones: the coldest polar zone, warm and humid tropical zone, and the moderate temperate zone.
What is the third layer of the ocean called?
The three main layers of the ocean are the epipelagic zone, the mesopelagic zone, and the bathypelagic zone.
What are the 7 layers of the ocean?
Ocean zones and what creatures live in them
- Sunlight Zone. This zone extends from the surface down to about 700 feet.
- Twilight Zone. This zone extends from 700 feet down to about 3,280 feet.
- The Midnight Zone. This zone extends from 3,280 feet to 13,125 feet.
- The Abyssal Zone.
- The Trenches.
