Ian Hendy: The course here at the University of Portsmouth for Marine Biology is a three-year degree. And the course is accredited with the Royal Society Biology. This is actually very important because it gives a really good firm accreditation for seal of approval for our degree.  

In our first year, they'll be based at the town campus where they have lots of lab facilities looking at microbiology and DNA extractions. But down here at the Institute of Marine Sciences, we have a large vessel where we could do some deep sea benthic trials. We have a smaller vessel where we can map seagrass habitats and kelp forests using sonar. We have oyster restoration and we also have coastal development and looking at habitat fragmentation and restoration.

The placement opportunity is an optional module. This could be locally, nationally or actual fact international as well. All governments have called for a climate crisis. Students can potentially find themselves in jobs such as charities, non-government organisations, working towards sustainability of restoration, benthic taxonomists, looking at impacts of oil spills, and you could also work in the research industry as well. So there's a whole breadth of jobs you could find yourself doing.

Living in Portsmouth, particularly in Southsea, is a lovely place to live. We're surrounded by the Solent. You have the Isle of Wight right next to you, we have Langstone Harbour and Portsmouth Harbour. So for a marine biologist, it's a dream.

India's experience studying BSc (Hons) Marine Biology

India, a student on our Marine Biology BSc course, talks about her experiences on the programme as a first year.

Why did you choose to study Marine Biology at the University of Portsmouth?

India: I've always been really passionate about marine biology. I love the facilities that are available. I got a tour of the labs. I enquired a little bit about additional support and things too, because I have a disability myself. When they told me about the services, about ASDAC (Additional Support and Disability Advice Centre), I thought that seemed really good and it seemed a lot better than other universities I'd looked at.

What is your favourite thing about the Marine Biology course?

India: My favourite aspect of the course has been the practical side. Since I've been here I've done about five practical lab sessions. They've really given me a lot of skills as a scientist.

After you graduate, what are your plans for the future?

India: I've been quite interested in deep sea ecology for a while so I find the deep ocean really interesting. Another area that I'm really interested in is also sustainable fisheries and aquaculture.

What would you say to convince someone to study Marine Biology at the University of Portsmouth?

India: Something that I've noticed since I've been here is how amazing the lecturers are. I think that the amount of support available at the university is exceptional really, but I'd also say that the facilities are amazing and in terms of science, there are some really great labs and great lab equipment.

Careers and opportunities

Marine biology is the study of the organisms, plants and animals that make up the world's saltwater ecosystems. It's a vital area of science when it comes to protecting our oceans and seas - marine biologists aim to better understand marine environments and to investigate the factors that alter marine ecosystems, both natural and man-made.

On this BSc (Hons) Marine Biology degree, you'll learn about a wide array of marine organisms, from phytoplankton to cetaceans, and how to protect the oceans and their delicate ecosystems against the growing threats of climate change, habitat destruction and resource exploitation.

You’ll conduct fieldwork in a range of intertidal habitats, including rocky shores, estuaries, saltmarsh and mangroves, and become an expert in diverse and rich marine ecosystems, from coral reefs to the deep sea.

When you graduate, you'll be ready for a career in a range of marine science areas, such as conservation, resource management and aquaculture, or to pursue academic research, lab work, field work or policy making.

You could also continue your studies at postgraduate level. Many graduates go onto study MRes Science or MSc Applied Aquatic Biology.


You'll also be able to apply to be a Registered Marine Scientist and you'll meet some of the academic requirements to become a Chartered Marine Scientist. And you'll be eligible to apply for Associate Membership of the Royal Society of Biology, which includes access to exclusive grants and awards.

I think that the amount of support available at the University is exceptional really, but I'd also say that the facilities are amazing and in terms of science, there are some really great labs and great lab equipment.

How you'll spend your time

One of the main differences between school or college and university is how much control you have over your learning.

We use a blended learning approach to teaching, which means you’ll take part in both face-to-face and online activities during your studies.  As well as attending your timetabled classes you'll study independently in your free time, supported by staff and our virtual learning environment, Moodle.

A typical week

We recommend you spend at least 35 hours a week studying for your Marine Biology degree. In your first year, you’ll be in timetabled teaching activities such as tutorials, lectures, practical classes and workshops and external visits for about 11 hours a week. The rest of the time you’ll do independent study such as research, reading, coursework and project work, alone or in a group with others from your course. You'll probably do more independent study and have less scheduled teaching in years 2 and 3, but this depends on which modules you choose.

Most timetabled teaching takes place during the day, Monday to Friday. You may occasionally need to go to University and course events in the evenings and at weekends.

Term dates

The academic year runs from September to June. There are breaks at Christmas and Easter.
