What is oceanic zone?

What is oceanic zone?

The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (such as the Neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 meters (660 feet), seaward from the coast into the open ocean with its Pelagic zone.

What are the 4 ocean zones?

Pelagic zone

  • Neritic Zone. The Neritic zone lies above the continental shelf.
  • Oceanic zone. The Oceanic zone extends from the edge of the continental shelf over the continental slope to the ocean floor beyond.
  • Epipelagic zone.
  • Mesopelagic zone.
  • Bathypelagic zone.

What are the 3 oceanic zones?

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)

What are the five zones of the oceanic 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 …

What are the oceanic divisions?

Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.

Which is the largest ocean zone?

However, there are a few sea creatures who swim this far down to feed, such as sperm whales. In fact, being fifteen times the size of the epipelagic zone, the bathypelagic is generally regarded as the world’s largest ecosystem.

Which ocean zone is the saltiest?

Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis.

What is the darkest zone in the ocean?

The deepest layer of the world’s oceans gets no sunlight at all. This dark ocean layer is called the midnight zone or the aphotic zone (aphotic means “no light” in Greek). The depth of this zone depends on the clarity or murkiness of the water.

Can humans survive in the midnight zone?

The deepest was almost 11,000 meters (36,000 feet) down—deeper than Mount Everest is tall. To withstand such crushing pressures, the sub’s two-person crew compartment is wrapped in a nine-centimeter (3.5-inch) titanium cocoon. It also carries up to 96 hours’ worth of emergency oxygen.
