Experience
Benefit from fieldwork, near and far
My favourite memory was Costa Rica. I went with a few lecturers on a research project for two weeks of roaming the beaches, the mangroves and going hiking and collecting samples.
The experiences Ashley gained during her degree has led her to wanting a career in research, with a particular interest in eco engineering.
- data and sample collection and analysis in varied marine habitats
- experience using scientific equipment and technology
- scientific writing and reporting, preparing you for careers in research and conservation
- teamwork in challenging and dynamic field conditions
- problem-solving in real-world ecological research
The years I spent at the University were some of the best of my life, both personally and ‘professionally’. The quality and diversity of the content taught is really good, but it’s the people that have made my experience incredible. I learnt from some of the best researchers in the field, passionate about their work and teaching, always there to push and encourage you to follow your passion and try new things, as well as from the other equally passionate students with whom I made some of the strongest friendships to date.
“The main reason I chose this uni is because they have a massive emphasis on fieldwork and getting your hands dirty – the most fun part of it.”
Facilities to support your learning
I learnt so much on my course, everything from practical skills conducting ecological surveys in the field, taxonomic knowledge of marine organisms through to data analysis and report writing. I also had the opportunity to learn skills in commercial diving, power boating, first aid and sea survival, which I wouldn’t have had the chance to undertake had I chosen to study my undergraduate degree at another university.
Expand your horizons with a research expedition
- taken part in cetacean surveys aboard the University yacht, Take The Helm, between Plymouth and the Isles of Scilly
- carried out assessments of south-west UK fish nurseries, catching, identifying and measuring juvenile fish in a number of key estuary sites
- spent two weeks on a field course in North Sulawesi (Bunaken and Bangka islands) where they learned about the biodiversity of coral reefs and how to monitor them
- enjoyed a week in the Azores, collecting data to assess the relative abundance of different colour forms of Clouded Yellow butterflies.
I felt very fortunate to have the opportunity to be taught about coral reefs by experts while directly observing the reef. I don't think many learning experiences can top that.

Hop aboard the University's own yacht, Take the Helm, and discover what it's like to take part in a four-day marine mammal survey.

Learn from experts
The good thing about the University’s location is that Plymouth is home to a number of marine organisations (the Marine Biological Association, Plymouth Marine Laboratory, Shark Trust, etc.), which provide countless opportunities for volunteering, collaborations and networking. For me, two separate bouts of volunteering at the MBA led to further research positions overseas through connections and referrals.

“Come down to Plymouth and see the University – and especially the Marine Station. Speak to the subject ambassadors and ask as many questions as you like. We love to talk about our degree. And then, take a walk around Plymouth, especially the Hoe. This is a city that has everything within walking distance. It’s beautiful and has so many opportunities for volunteering and work experience within the marine biology field.”
Careers
Plymouth makes you more passionate about the ocean and studying here kept me on the right path. I wanted to be by the ocean, I wanted to dive, I wanted to surf and I wanted to study with the best marine biologists in the country. Plymouth was fantastic for me and I will always love it.

Why you should do a placement
I think that the human aspect of a placement year, which allows you to grow and mature, is just as important as the professional skills you acquire. Get out there, learn about marine biology topics, learn about yourself, and come back to uni with a better idea of who you are and where you are heading!
