What is the dark zone in the ocean?

The bathyal zone or bathypelagic – from Greek βαθύς (bathýs), deep – (also known as midnight zone) is the part of the open ocean that extends from a depth of 1,000 to 4,000 m (3,300 to 13,100 ft) below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.

Why is the dark zone in the ocean important?

The deeper you go, the darker the water gets. That’s because sunlight cannot penetrate very far under water. Sunlight is needed for photosynthesis. So the depth of water determines whether photosynthesis is possible.

How much of the ocean is the dark zone?

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. “Abyss” derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness. It covers 83% of the total area of the ocean and 60% of Earth’s surface.

What animals live in the midnight zone list?

How deep is the midnight zone?

between 1,000 and 4,000 meters
The aphotic zone is further subdivided into the bathypelagic zone (or midnight zone) between 1,000 and 4,000 meters, the abyssopelagic (or the abyss) between 4,000 and 6,000 meters, and the hadopelagic zone (or hadal zone) 6,000 meters and deeper.

How cold is the midnight zone?

39°F
The temperature never fluctuates far from a chilling 39°F (4°C). The pressure in the bathypelagic zone is extreme and at depths of 13,100 feet (4,000 meters), reaches over 5850 pounds per square inch!
