Course summary

The MBiol Marine and Freshwater Biology degree at Aberystwyth University is one of only a few nationally to provide you with an integrated catchment to ocean understanding of the biology, ecology and stressors affecting these intimately interconnected ecosystems. This is crucial, given that they support some of the most threatened species and habitats on the planet.

This four-year Integrated Masters offers you the opportunity to combine a BSc with an extra year of study so that you graduate with a Masters-level qualification. The course will develop the breadth and depth of your knowledge of marine and freshwater biology and prepare you to be a subject specialist, with the ability to tackle the global marine and freshwater challenges we face.

Situated on the coast of Cardigan Bay, Aberystwyth is one of the best places in the UK to study marine and freshwater biology. You will have easy access to rocky and sandy shores, estuaries of conservation importance, as well as near-pristine rivers and lakes. Cardigan Bay is also home to the largest residential population of bottlenose dolphins in the UK. 
The first three years of the course will follow the same syllabus as BSc Marine and Freshwater Biology (C164), which is then followed by an additional year of study, after which you will graduate with a Masters-level qualification. This course has attained advanced accreditation from the Royal Society of Biology.

On this course you will develop practical skills in the sampling techniques used in the aquatic environment, the critical analysis of data and literature, and the presentation of your findings to a variety of stakeholders. This will ensure you are well prepared for professional roles that seek to understand and address the various challenges facing marine and freshwater organisms and ecosystems.

To support your learning, you will have access to two research vessels enabling you to gain real hands-on experience of the sampling techniques used by professional marine and freshwater biologists as well as use of our aquarium systems for experimental studies of marine and freshwater organisms.

Fieldwork and practical classes form an integral part of the course throughout. An optional residential two-centre field course in your third year, currently based in Portugal and Scotland, will allow you to immerse yourself in the study of marine and freshwater biology further afield.

The Integrated Masters degree in Marine and Freshwater Biology is designed to develop the breadth and depth of your knowledge, along with the competence and confidence in research methods required to pursue a career as a professional scientist. Marine and Freshwater Biology graduates are equipped with the skills and knowledge to enter a wide range of careers including ecological consultancy, environmental management and conservation, teaching and scientific journalism. The MBiol is also a recognised alternative to MSc for progression to a PhD studentship, and an excellent foundation for a career as a professional scientist.
