What Does a Marine Biologist Do?

Have you ever dreamed about spending your days under the sea? Perhaps you’ve wished you could become a fish or a whale so you’d never have to leave the ocean.

If this sounds super fun, then you may have a keen interest in Marine Biology, which is the study of living things in the ocean.

What does a Marine Biologist do?

This career covers a lot of ground...err…water, so grab your snorkel and flippers and let’s dive right into the world of Marine Biology.

The Study of Marine Biology

The word “marine” refers to saltwater environments. So a Marine Biologists does not work with lakes, streams, or rivers.

A Marine Biologist can work with anything in the ocean or the wetlands, or any place that saltwater and freshwater mix. They make discoveries involving the tiniest of bacteria, all the way up to whales, sharks, and turtles.

The BIG Stuff

For example, this career may find you mapping the migration pattern of a species of whale, or the number of sharks that inhabit a particular region, or even how dolphins communicate under water.

The Marine Biologist may look for large creatures in deep sea trenches, along coastlines or the middle of the ocean. They can also work in aquariums so they can study these animals up close.

The Tiny Stuff

PlanktonEven though we can’t see them without a magnifying glass or a microscope, the ocean is filled with teeny tiny animals, plants, and plant-like algae. These are called “plankton,” and they are essential to life in the sea.

Plankton is a food source for many sea creatures. By studying these micro-organisms, the Marine Biologist can figure out which fish or whales are in the area (many whales only eat plankton). This type of algae can also tell the Marine Biologist if the ocean is healthy. Too much plankton, or too little, can be a sign that the ocean is unbalanced.

What Do I Need to Be a Marine Biologist?

While you are in school, you will also want to focus on subjects relevant to Marine Biology including biology, physics, chemistry, and mathematics.

As part of their job, a Marine Biologist may collect and analyze biological data, study plant life, identify animal species, research environmental effects, communicate findings to the public, and much more. Along the path to being a Marine Biologist, you may also decide to focus your study on a particular group of animals.

Although a bachelor’s degree in Marine Biology is sufficient for many related jobs, a Ph.D. is usually required for independent research and university teaching if you choose to go that route.

With a lot of work and a real love of all things “oceany,” you may one day become a Marine Biologist. Who knows? You may even discover a new species.
