Course Overview

Due to vital ongoing issues with our oceans, an academic understanding of ocean life across the world has never been more important.

Our Marine Biology degree will provide you with the knowledge and skills needed to make meaningful contributions towards solving current environmental and societal challenges. The breadth and depth of the curriculum allows you to develop a deep understanding of marine ecosystems and the biological principles that govern life in our oceans. 

The programme encourages you to consider the impact of human activity on marine environments, and to explore sustainable approaches to conservation. 
As a graduate, you will be equipped to become an advocate for the ocean, contributing to solutions for climate change, pollution, habitat loss and biodiversity decline.
You will also gain proficiency in laboratory and field techniques, data analysis, and scientific communication, preparing you to tackle global issues such as biodiversity loss, climate change, and other environmental crises. 

Our degree uses ethical, sustainable and innovative approaches to fully prepare you for a range of meaningful careers in areas including marine science, conservation, and environmental management.

Your Marine Biology Experience

Boat work on the Research Vessel Mary Anning, fieldwork on local shores and work in our cutting-edge laboratories are all core parts of the degree. As Marine Biology is so broad, you can tailor your path to be field or lab focused, depending on your interests.
Your first year will deliver a solid grounding in biology, encompassing the diversity of life, cellular and microbial biology, animal behaviour, ecology, evolution, genetics and the importance of the oceans to life on Earth. You will also learn the core skills of scientific writing, and data presentation and analysis.

You will begin to fully specialise in marine biology in your second year, with a range of dedicated modules and a residential field course. Year two contains a substantial amount of fieldwork on local shores, and aboard our research vessel, the RV Mary Anning, equipping you with real-world practical experience and important skills. 

Year 3 allows you to develop advanced skills ready for your career, including surveying, project management and data presentation. You can also choose to undertake an international field course teaching tropical ecology and in-water surveying skills, with past locations including India, Borneo and Puerto Rico. The year will complete with a capstone research project.

This programme includes opportunities to undertake a Year Abroad, offering invaluable life experience. 

This course also offers you the opportunity to spend a Year in Industry, in the UK or overseas, enabling you to gain valuable workplace experience. The University advocates for paid-only placements, which on average have a salary of over £20,000. Unpaid placements are considered on a case-by-case basis. 
The Year in Applied Research enables you to develop advanced research skills. You will be housed in our research groups, on exchange with our partners in Exeter or Aberystwyth, or can be linked with industry, or a combination of these options.

The optional Foundation Year for this programme can give you an exciting introduction to higher education, setting you up with the skills, confidence, and knowledge that you’ll need to be successful in your undergraduate degree. It’s ideal if you need a little more support after further education, or are returning to education after a gap. Following successful completion of the Foundation Year, you will progress onto Year 1 of your BSc.
