The Marine Abyssal Zone

Main Ideas About The Marine Abyssal

• 1500 to 10,000 Meters Deep
• Temperature is 2 to 3 degrees celsius
• Scarce Food and Sunlight

Hello, my name is Daedra. I am a ninth grade student from Central High School. This is my webpage for Mr. P's Class on the Marine Abyssal Zone, which is the deepest part of the ocean!

The Abyssal Zone is approx. 1500 to 10,000 meters deep, which is the deepest part of the ocean! No human would be able to survive that great of an amount of pressure. Our heads would probably explode! The Abyssal Zone is very cold since it is so deep and is reached by very little sunlight. The temperature is usually 2 to 3 degrees celsius! Brrr! There is very little food, therefore very little marine abyssal wildlife. Some organisms that are included are the lantern fish and the coelcanth. The coelcanth was once believed to be extinct by many scientists. It was later found in the abyssal zone of the Indian Ocean. Most of the organisms that live in the abyssal zone are only a few millimeters long due to lack of food and sunlight. The organisms only are able to eat what is left over from other animals, such as sharks and whales.

The floor of the abyssal zone features vents formed by spreading tectonic plates which release hydrogen sulfide and other minerals which are consumed by bacteria. Sometimes lava even comes up through the vents but is cooled very quickly because of the cold temperatures.

At this point there are no environmental issues, but no one really knows because it is too deep to explore. The pressure is just too great! But it is an interesting biome because of the species in the zone and the different facts from history about them.
