Marine Biologist

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

Marine biologists may perform the following tasks:

estimate the number of marine organisms and analyse their population features
observe communities of marine organisms and work out the factors influencing their structure
assess and advise on the causes, effects, prevention and control of introduced species
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
participate in studies aimed at predicting the effects of proposed developments
develop long-term programs for monitoring environmental pollution
manage fisheries
provide information and recommendations for the development of marine conservation and harvesting policies and programs, including aquaculture
write scientific reports on research and investigations, and prepare 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 Ecologist

A marine ecologist studies the interrelationships between marine organisms and their environment.

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

In many cases, much of the work of marine biologists involves office work, research, writing reports and long hours in laboratories. Very few graduates get the glamorous job of swimming with dolphins and whales.
