Working hours and conditions

Working Hours

In research and higher education, you would usually work regular hours, Monday to Friday. As a field researcher you would work variable or irregular hours, involving periods at sea or on location at a fieldwork station.

Conditions

As a marine scientist you would split your time between working in a laboratory, fieldwork on sea-going vessels, and time in an office. You may also need to monitor experiments for long periods in a laboratory. You would need to spend time writing up and recording your research. You may travel internationally to sites of scientific interest.

A diving certification may be required.

How to become an Marine Scientist?

Entry Level Education

Marine scientist are often biologists, but marine scientists may also have degrees in other scientific areas such as chemistry, geology, physics or ecology. To get into these courses you usually need to gain your senior secondary school certificate or equivalent. English, mathematics, chemistry, biology and physics would be appropriate subjects to study prior to university.

In order to work in research or academic roles, you would need a bachelor's degree at minimum, a master's degree for advancement, and a PhD for individual research or teaching.

Job outlook

  • 1 2 3 4 5

Employment of marine scientists is projected to grow slower than the average for all occupations.

More marine will be needed to study the impacts of human population, climate change and other factors on marine environments, coastlines and the sea bed. However, because much of the funding for this research comes from government agencies, demand for marine scientists is likely to be limited by budgetary constraints.
