Ocean Water Zones

Oceanography

QuestionAnswer
Abyssopelagic zone - Deepest zone -There is no light in the abyss - Temperature of the water is near freezing -Ranges from -4,000m to -6,000m
Bathypelagic zone -Below the mesopelagic zone and is -also known as the midnight zone. -No light reaches the bathypelagic zone -Extends from -1,000m to -4,000 m
Epipelagic zone *Uppermost zone *Often referred to as the sunlight zone. *Enough light for photosynthesis to occur. *From the surface down to -200m depth *Temperatures from 27-104ºF
Hadalpelagic zone extends from 6,000 m to the bottom of the deepest parts of the oceans. The hadalpelagic zone includes deep water trenches and canyons.
Intertidal zone – Area between high and low tide and is subject to harsh environmental conditions. The intertidal zone is also called the littoral zone and is divided into four zones: spray zone, high tide zone, middle tide zone, and low tide zone.
Mesopelagic zone The mesopelagic zone is directly below the epipelagic zone and is often referred to as the twilight zone. This zone ranges from 200 m to 1,000 m (656 ft-3,281 ft). While some light reaches this zone, there is not enough light for photosynthesis to o
Littoral zone – Zone between low and high tide. Also called intertidal zone.
Spray zone The spray zone is a section of the intertidal zone far up on the beach and does not include the high tide zone. This zone will occasionally be sprayed by incoming waves. This zone is covered by water only during unusually high tides or storms.
High tide – The high tide zone is covered by water only during a high tide. As the tide recedes (or goes back to sea), pools of seawater are left to evaporate in the hot sun. High tide is also called the upper mid-littoral zone.
