Marine Biology

Career Description

Marine scientists are involved in research, analysis and forecasts in relation to the oceans, their life forms and coastal areas. They analyse the sea and its interaction with the land, atmosphere and sea floors and use the information gained to predict changes to the earth’s infrastructure, inform statutory legislation and encourage environmental protection.

Marine biologists perform many varied tasks depending on their area of specialization and the area they are working in. As part of research they could estimate numbers of marine animals, study communities of marine organisms or assess the effect of introduced species. They may develop programs for monitoring pollution and provide information on marine conservation. They will spend time preparing scientific reports and papers. They may also be involved in teaching and giving advice to managers, politicians, primary producers and the public.  


  • keen interest in research
  • excellent oral and written communication skills
  • an analytical mind and a logical approach to problem solving
  • good observation skills
  • to be able to swim and scuba dive
  • to be able to work independently or as part of a team.

Educational Requirements

Students applying for marine biology positions need to fulfill the following marine biologist education requirements:

  • High school diploma or GED
  • Bachelor's degree in biology or related sciences
  • Internship or externship in the field
  • Masters of Science Degree in Marine Biology or Marine Science
  • Doctorate Degree in Marine Biology (optional)

Kaplan is one of the best marine biology schools in the country

Salary Expectations

Life scientists (which include marine biologists) can expect to earn approximately $1200.00 per week (full-time and before tax) depending on their experience and employer.

Future Outlook

The employment outlook in this field is highly competitive. The supply of marine scientists far exceeds the demand, and the number of government jobs (the federal and state governments are important employers) is limited.

Other employers are local governments, aquarium/museums, colleges and universities, and private research laboratories or consulting firms. In fishery science, where the study of fish and marine mammal population dynamics is in the most demand, a strong background in advanced mathematics and computer skills in addition to course work in the animal and aquatic sciences is critical for getting a competitive edge in the job market.

Also, more universities are offering courses and programs in fisheries or wildlife management, another increasingly important aspect of the study of fishes, marine mammals, and sea turtles.


Benefits to becoming a marine biologist is that you get to help the oceans ecosystem and do what you love. Most people become a marine biologist because they love to be in the ocean and study the things that live in it. You can swim and study creatures of the ocean at the same time.
