How deep is the open sea zone?

How deep is the open sea zone?

The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …

How many animals live in open ocean?

Ocean Life Scientists estimate that about one million species of animals live in the ocean. But most of them—95 percent—are invertebrates, animals that don’t have a backbone, such as jellyfish and shrimp.

How many open oceans are there?

There is only one global ocean. Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries – including the United States – now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.

What is the open water zone?

The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas. Epipelagic zone (ocean surface to 200 meters deep). This is the zone in which photosynthesis can occur, because light is available.

Why is the open ocean important?

The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

What animals live in open ocean?

mollusks such as octopus and squid as well as many mammals including species of whales and dolphins. plankton. Whales, sharks, octopus, dolphins, sea cucumbers, squids.

Where are open oceans found?

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths.

What is it like in the open ocean?

The area of the open ocean where sunlight shines through the water is called the photic zone. Most life in the open ocean is found in the photic zone. Animals, protists, plants, and bacteria that float or drift in ocean water are called plankton. They are moved around the open ocean by surface currents and wind.

What creatures live in the open ocean?

At this depth and pressure, the animals most commonly found are fish, mollusks, crustaceans, and jellyfish. Sperm whales will hunt at these depths on occasion to prey on giant squid.

Where are the open oceans located in the world?

The open oceans or pelagic ecosystems are the areas away from the coastal boundaries and above the seabed. It encompasses the entire water column and lies beyond the edge of the continental shelf. It extends from the tropics to the polar regions and from the sea surface to the abyssal depths. It is a highly heterogeneous and dynamic habitat.

Which is the Dark Zone of the ocean?

Bathypelagic zone (1,000-4,000m) – This is a dark zone where water pressure is high and the water is cold (around 35-39 degrees). Abyssopelagic zone (4,000-6,000m) – This is the zone past the continental slope – the deep water just over the ocean bottom. This is also known as the abyssal zone.

Is the open ocean part of the pelagic zone?

The pelagic zone is the area of the ocean outside of coastal areas. This is also called the open ocean. The open ocean lies over and beyond the continental shelf. It’s where you’ll find some of the biggest marine life species. The sea floor (demersal zone) is not included in the pelagic zone.

Which is the most productive zone of the ocean?

There are several zone of environment depends on light intensity, as follows: Photic Zone, a zone where the sunrays still can penetrate the sea, maximal depth is 200 m. It is the primary productive zone in the ocean. Twilight Zone, has little light, not effective for photosyntesis, thus not many plants live here. The depth is 200 – 2000 m.
