Marine Biologist

Marine biologists study the origin, structure, functions and behaviour of all forms of life in the sea and connected rivers and lakes, their relationships with each other, and how they are affected by environmental factors.

Marine biologists may perform the following tasks:

  • estimate the numbers of marine organisms and analyse their population features
  • observe the structure of communities of marine organisms and work out the factors influencing this structure
  • assess and advise on introduced species - causes, effects, prevention and control
  • use numerical and statistical skills to design laboratory and field experiments
  • design and carry out environmental impact assessments to work out whether change is caused by natural or human factors
  • develop long-term programs for monitoring environmental pollution
  • provide information and recommendations for the development of marine conservation and harvesting policies, including aquaculture
  • write scientific reports on research and investigations, and more general information for scientific, managerial, political and general audiences
  • provide advice to managers, politicians, primary producers, health care workers and the general public
  • provide research training for students and staff seeking entry to this field.

Marine biologists are required to work both in the laboratory and for extended periods at sea or shore-based field stations. Field work may include working on commercial fishing vessels and small inshore vessels and scuba diving.

It should also be noted that much of the work of many marine biologists involves office work, research, writing of reports and long hours in laboratories. Very few graduates get the ideal job of swimming with dolphins and whales!
