Transcript of Oceanic Zone

Oceanic Zone
Oceanic Zone
The oceanic zone is a zone in earth's ocean that begins where the water measures 200 feet or deeper off shore. The oceanic zone contains 65% of the ocean's completely open water and is the region of open sea beyond the continental shelf. The oceanic zone is also home to a wide variety of undersea terrain such as crevices,deep sea volcanoes, and ocean basins. Although it is difficult to, some organisms live in the oceanic zone
Subzones
Oceanic Zone Location
Since the oceanic zone possesses most of the ocean's completely open water, it is found off the continental slopes of the ocean
The oceanic zone is divided into three subzones. Those subzones are the epipelagic,mesopelagic, and bathypelagic
Epipelagic Zone
The epipelagic zone, also known as the sunlit zone, houses most of the wildlife in the oceanic zone, This is because it receives just enough sunlight to support photosynthesis
Mesopelagic Zone
The subzone underneath the epipelagic is the mesopelagic. This zone is often referred to as the twilight zone due to it's little amount of light. The pressure in this subzone is high and can range from 5 to 4 degrees celsius
Bathypelagic Zone
The bathypelagic zone is the zone where 90% of the ocean lies. No light can penetrate this zone and it is often referred to as the midnight zone. The water pressure is extremely intense and the temperatures are below freezing
Animals
A lot of the animals found in the oceanic zone mostly live in the epipelagic subzone. Animals in other subzones must be able to survive in conditions where there is no light. Some of the animals in the oceanic zone include:
Whale
Sharks
Krill
Clams
Hatchetfish
Plants
Just like animals, plants in this zone thrive mainly in the epipelagic subzone. One reason why is because the epipelagic subzone supports photosynthesis. Some plants include:
Phytoplankton
Zooplankton
Seaweed
