Everything You Need to Know About Marine Biology (The Study of Life in Oceans & Seas)

If you grew up surrounded by (or dreaming of) the the ocean, chances are a career in marine biology sounds pretty amazing. After all, marine biologists study the organisms and ecology of saltwater ecosystems, like the oceans and seas. So getting out on the water is often a job requirement.

And while "marine biologist" isn't typically a job title, that's actually a ​good​ thing. Marine biologists can perform a range of jobs, so you can combine your love of the oceans and seas with your passion for math, chemistry, physics, ecology or even medicine to find the right marine biology job for you.

So put on your scuba gear and get ready to dive in! Here's what you need to know about marine biology, what marine biologists do, and some fun science kits to help you get started.

What Is Marine Biology?

At the most basic level, marine biology is the study of saltwater ecosystems: our oceans and seas. Marine biologists study multiple aspects of sea and ocean life. They might study the plants and animals that live in the sea, from massive kelp forests (dense seaweed forests that span for miles) to playful dolphins. They also study insects and microscopic species found in salt water ecosystems. And marine biologists might combine their work with other scientific disciplines: For example, a marine biologist and geologist might study volcanic thermal vents on the ocean's floor.

What Do Marine Biologists Do?

Like we mentioned, it's rare you'll find "marine biologist" on a job posting. Instead, marine biologists use the skills and specializations they learned in school to do a range of jobs. Those might include:

Marine Biology Research

Universities and other research institutions hire marine biologists to design and conduct experiments. If you're a research marine biologist, you might be heading out on the sea to collect samples or data (also called fieldwork), then running tests or conducting experiments to better understand the samples you collected. You'd also be writing research reports and scientific papers to share what you found.

Marine Conservation Work (a.k.a. Saving the Oceans)

If you're into marine biology, you already know that our oceans and seas are changing – a result of climate change. And marine biologists are important in helping figure out exactly how the oceans and seas are impacted by climate change, and what we can do to save them. If you become a marine conservation biologist, you might give governments or companies advice on the best ways to keep the oceans as clean of pollutants and safe as possible.

Marine Health Sciences

Torn between being a marine biologist or a doctor? Good news, you don't have to choose. Marine biologists can also become doctors or veterinarians to help advance health science. Marine veterinarians might help us understand and treat diseases that affect marine species and marine life. And marine doctors might look into how marine organisms or compounds found in marine ecosystems impact human health (like looking into how a chemical in seaweed, for instance, might be used for medicine).

There are many more career options, too. You could use your marine biology education to become a teacher or professor, work at a zoo or become an ocean engineer.
