Marine Biologist as a Career – Marine Biology Career Paths

How To Become A Marine Biologist?

Did you ever stand on the shore and wondered what treasure is hidden in the deep blue sea? Where are the waves coming from, and who are the neighbors of the jellyfishes or the shells? Did you ever have the urge to dive in and explore the depths? – if you have, then a Marine Biologist job is perfect for you.

The term “marine biologist” is applied in many disciplines and jobs in the marine sciences. Though many biologists study both which deal with the study of marine life, and also deal with the physical properties of the sea, Marine biology or Marine science is the study of the environment and all aspects of life in the sea. This includes marine animals, plants, and other organisms, including both vertebrate and invertebrate, in shallow seas, deep oceans, and the laboratory. The main aims of marine biology are to understand the marine world better and to comprehend and predict changes in ecosystems affected by natural disturbances and human. So a marine biologist might be a biological technician, ichthyologist, microbiologist, systems analyst, fishery biologist, marine mammalogist, or a mathematician.

Marine Biology Fields That You Can Choose

This is a broad-ranging career. You could go into academic research, fieldwork, laboratory work, consulting, outreach, or policymaking. You can choose from any of the following-

Although most roles require good research and scientific skills, specializing in a particular area, even a strong technical skill, is usually required for career progression – whether in coastal management,  invertebrate biodiversity, fisheries biology, reef ecology, or marine pollution.

There are a number of marine science-related undergraduate and postgraduate degrees, but the key to having a successful career in these streams is by having relevant experience, either voluntary or paid. To prove your commitment and to develop your skillset, you need to be constantly on the lookout for opportunities and seize them at the right time as there is a lot of competition for jobs in this field.


To become a marine biologist, you’ll need to focus on a marine-oriented degree such as:

  • Marine biology
  • Marine biology and coastal ecology/oceanography
  • Marine science
  • Ocean and earth science
  • Oceanography

You can enroll in programs like Bachelor of Science in Marine Biology, Master of Science in Marine Biology, Certificate courses in Marine Biology, Master of Philosophy (M.Phil.) in Marine Biology. Doctor of Philosophy (Ph.D.) in Marine Biology according to your qualifications and eligibility.

If your undergraduate degree is a broader-based science degree, like botany, zoology or microbiology, you need to do postgraduate in the marine-related study.

Careers in marine biology are often research-based and, while it’s possible to study marine biology undergraduate degree and enroll in a semi-employed position on a conservation science project or go straight into volunteering, postgraduate study is required for better career prospects.

Postgraduate degrees range from Tropical coastal management to Masters in tropical marine biology and aquatic ecology and conservation. To have your career options open, studying more general science-based undergraduate degrees is suggested, after which you can specialize in your Master’s degree.

If you’re following an academic path in marine geochemistry or chemistry oceanography, ocean and earth science, and behavioral ecology, PhDs can be advantageous. Marine research organizations and universities conduct Ph.D. programs, and you may be able to undertake your studies on a part-time basis while working. The selection of a supervisor is essential. It’s better to select someone who is working in the specialist area that interests you.
