Biological oceanography

Biological oceanography is like taking a really close look at all the animals and plants that live in the ocean! Imagine going on a big adventure under the water to explore all the different creatures and what they do to survive.

Scientists who study biological oceanography use cool tools like special underwater cameras and nets to catch tiny plankton and larger fish. They also take measurements of things like water temperature, saltiness, and how much oxygen is in the water, because these things can affect the ocean animals.

Just like how we need food and water to stay alive, the animals and plants in the ocean also have to eat and drink to survive. So the scientists study what different species of animals like to eat, and also what eats them! Some animals also rely on sunlight to make food through a process called photosynthesis, which the scientists also study.

Sometimes, the biological oceanographers have to go on really big ships to go out to the middle of the ocean to do their research. It's a big job, but it's important to help us understand how to take care of the ocean and everything living in it.
