Studying marine biology abroad

What is marine biology?

Marine biology is the study of life in oceans, seas and other saltwater environments. It explores how marine organisms – from tiny plankton to giant whales – live, grow and interact with their surroundings.

This field also examines how ocean systems function and how human activities affect marine life and habitats.

Marine biology draws on subjects like biology, chemistry, oceanography and environmental science. As a student, you might learn how coral reefs develop, study migration patterns of marine animals, or investigate how climate change impacts sea ecosystems.

Your work could take place in laboratories, along coastlines, or out at sea on research vessels.

Why study marine biology abroad?

Learning marine biology in another country gives you the chance to study species and environments you might never encounter at home.

You could observe dolphins in the Mediterranean, explore coral reefs in the Great Barrier Reef, or collect samples from Arctic waters.

By studying in different locations, you gain experience with diverse marine environments and research techniques. You’ll also develop an international perspective on ocean conservation and build connections with scientists, marine parks and conservation groups around the world.

What you will study

Marine biology degrees often combine theory with practical fieldwork. Areas you might cover include:

• Marine Ecology – how marine plants and animals interact with each other and their habitats.
• Oceanography – the physical and chemical processes that shape the oceans.
• Fisheries Science – sustainable management of fish and other marine resources.
• Conservation Biology – protecting endangered species and fragile marine ecosystems.
• Marine Microbiology – studying microscopic organisms that form the base of ocean food chains.
• Climate and the Oceans – understanding how climate change influences marine life and habitats.
• Field and Lab Research Skills – collecting, analysing and presenting scientific data.

Many programmes include research trips, diving opportunities, internships at aquariums, or placements with marine conservation organisations.

Related subjects you might also like:

• Oceanography
• Environmental Science
• Ecology
• Aquaculture
• Zoology

Accreditation

At undergraduate level, most students graduate with a Bachelor of Science (BSc) in Marine Biology or a closely related subject such as Marine Science or Biological Oceanography. Some universities also offer Bachelor of Arts (BA) programmes that include marine studies alongside social sciences or environmental policy.

At postgraduate level, you could take a Master of Science (MSc) or Master of Research (MRes) in Marine Biology, Marine Conservation, or Oceanography. You may choose to specialise in areas like marine mammal science, coral reef ecology, or sustainable fisheries. A PhD is often needed for high-level research or academic work.

Professional accreditation may be available in some regions for marine scientists, divers, or fisheries managers through recognised industry bodies.

Careers

A degree in marine biology can open the door to a wide range of careers. Some graduates become marine ecologists, studying ecosystems and advising on conservation strategies. Others work as fisheries scientists, helping to manage fish stocks sustainably.

Research roles are available in universities, marine research institutes and government agencies, often focusing on topics like ocean health, species behaviour, or climate change impacts. You could also work in aquariums or marine parks, managing animal care, public education programmes and conservation projects.

Some marine biologists choose careers in environmental consultancy, advising industries and governments on protecting marine environments. Others move into marine policy, education, or journalism, raising awareness about the importance of healthy oceans.

Because the oceans connect the entire planet, marine biology skills are valued worldwide – giving you opportunities to work on global projects that protect one of Earth’s most important resources.
