Pay will vary depending on your qualifications, experience and the type of work you are doing.
- Postdoctoral fellows usually earn between $60,000 and $65,000 a year.
- For permanent positions, and with a PhD, you can expect a starting salary between $60,000 and $85,000.
- With several years' experience and increased performance and responsibility, pay could rise to about $100,000 or more.
What you will do
Marine biologists may do some or all of the following:
- observe marine plants and animals in their natural environment
- study the impact of pollution on marine life
- identify, classify and preserve different types of marine life
- estimate population growth and life expectancy
- plan and run field studies and experiments
- use computer modelling techniques to predict future events in the marine environment
- report the results of their studies in papers for science journals and in commercial reports.
Freshwater biologists do similar work, except that they study plants and animals living in rivers, lakes and ponds.
Skills and knowledge
Marine biologists need to have:
- knowledge of marine science, biology, and chemistry
- research skills
- maths and computer skills
- writing skills, for writing reports and for publications.
- usually work regular office hours, but they may also work longer hours when doing fieldwork
- work in offices and laboratories, and they also work on boats, at sea, or in isolated coastal areas in all weather conditions
- travel to field study sites, and may travel around the country or overseas to attend conferences or training.
What's the job really like?
Drew Lohrer - Marine Biologist
Myth number one – marine biologists work with large animals only
"Some people think we work only with dolphins or whales, but it’s not always large animals like that. I mainly work on creatures that live on the sea floor. I focus on sea urchins, shellfish and worms, trying to understand their roles in the ecosystem."
Myth number two – marine biologists work in glamorous environments
Though the work is important, it's often done in an unglamorous environment. "When I dive, it’s mostly in low-visibility conditions, and my world view is often a patch of mud! However, I do get to go to exciting places like the Antarctic to study coastal systems. It is surreal diving there – the water is crystal clear and the types and amounts of animals you see are just astounding."
Myth number three – marine biologists get to dive all the time
"I don’t get to dive a lot of the time. But, there’s no monotony because I do different things all the time. Within a year, I might write proposals to get funding for what I want to do, then do fieldwork and perform experiments. Finally, I would analyse the data and write up my findings."
