Deep in the Ocean

Deep in the Ocean

Deep Underwater Imagine a trip to the deepest part of the ocean. What would you expect to see? Would it be dark or light? Would it be warm or cold? Would you find strange new animals and plants?

Sunlight warms the surface, or shallow parts, of the ocean. Plants and animals that need sunlight and warm water live there. Deep in the ocean, other animals live in water that is cold and dark.

Diving Deep in the Ocean The deep ocean is freezing cold. The weight, or water pressure, of very deep water can harm you. Sport divers wear air tanks for safety. Deep divers wear a special diving suit. Scientists ride in a small submarine called a submersible.

Oceanographers Scientists who study the ocean are called oceanographers (oh-shuh- NOG-ruh-furs). They often live for months on a ship. Some study what a sea animal eats and where it lives.

Using Satellites for Tracking Satellites can help to track sea animals' travels. Scientists tag some animals. A satellite can track the signal from the tag. The signal shows where the animal goes.
