How to become a marine biologist + what they really do

How to become a marine biologist

So you want to be a marine biologist. But how do you become one? And what do they really do?

Marine biology is the study of life in the ocean and other saltwater environments. It’s an amazing STEM career path for anyone who’s keen on conservation or passionate about the environment. Below, we’ve answered all your burning questions on how to become a marine biologist, including what to study, the skills you need and where you could end up working.

What skills do I need to become a marine biologist?

To be an awesome marine biologist, you’ll need:

  • A love of ocean life
  • To be good with numbers and statistics (for reporting)
  • The ability to do practical fieldwork
  • Teamwork and communication skills
  • Excellent observation skills
  • To be okay with working outdoors in all conditions

What do I need to study to become a marine biologist?

A degree in marine science or marine biology is super helpful, or even a Bachelor of Science with a major in marine biology or marine science.

Maya Santangelo is an undersea specialist, which means hanging with endangered hammerheads and swimming with great whites is as standard as grabbing a coffee or opening a word doc. Find out more about her STEM journey here.

What does a marine biologist actually do every day?

Research! They look at things like migration and evolution patterns of marine life, the health of marine environments, the human impact on marine animals and reefs, and how to repair damage to ecosystems.

A marine biologist conducts their research through:

  • Collecting specimens and samples from the field
  • Analysing and compiling data
  • Conducting experiments in the lab
  • Writing reports and papers

Common tools they use include cameras, sensors, drones, satellites, collecting nets and yep, you guessed it, scuba gear.

Where can you work as a marine biologist?

Lots of places. A marine biologist usually works in a lab, at sea or at a research station. They can work for the government, private research labs, aquariums, zoos, museums or in academia.

Can marine science jobs be creative?

They sure can. Marine science jobs are critical to keeping our rivers and oceans healthy, but are also an unexpected avenue into a creative career. We’ve got the lowdown on how a ceramicist is helping handfish to breed successfully, and how a CSIRO researcher is tapping in to her Indigenous heritage to track dugong populations.

What’s the average salary for a marine biologist?

According to payscale, the salary for a marine biologist can range from $43k to $106k. The average salary is $58,482.
