What is the Midnight Zone?

Back

The Midnight Zone is a layer of the ocean between 1000 to 4000 meters deep, characterized by no sunlight, immense water pressure, and the presence of bioluminescent organisms.

What process do phytoplankton use to absorb carbon from the atmosphere?

Back

Phytoplankton absorb carbon from the atmosphere through the process of Photosynthesis.

Front

What is bioluminescence?

Back

Bioluminescence is the production and emission of light by living organisms, often found in deep-sea creatures.

An Abyssal Plain is a flat or gently sloping area of the deep ocean floor, typically found at depths of 3000 to 6000 meters.

Front

What is ocean acidification?

Back

Ocean acidification refers to the decrease in pH levels of the ocean due to increased carbon dioxide absorption.
