Why study Marine biology at Essex?

At the University of Essex, we take pride in being ranked 7th for biology (non-specific) for overall positivity (National Student Survey 2024, English broad-discipline higher education institutions).

You'll join a community of renowned academic experts, dedicated to researching marine environments and driving significant change. Dr Michelle Taylor, whose recent research expedition to the Galapagos Islands exemplifies the global reach of our academic pursuits; and our team of Marine experts working with leading research organisations such as Centre for Environment, Fisheries and Aquaculture Science (Cefas).

You'll have access to facilities such as our on-site aquarium and the Marine Biology Field Centre, providing an ideal setting for your research projects.

As part of your studies you'll have incredible opportunities for field trips, both within the UK and abroad. Journey to locations like Scotland, Greece, and Indonesia (subject to additional costs), where, in the heart of the Coral Triangle, you will gain hands-on experience in diving and contribute to unique underwater research surveys. Your academic journey at Essex is not just a study; it's an adventure into marine research.

"I was lucky enough to receive an International Experience Bursary to help fund my travel to Tanzania where, as a Research Officer, I led lectures on a variety of topics such as seagrass and mangrove ecology, coral reef fish and invertebrate ID, turtle conservation and butterfly biology. I got to take part in an array of other experiences including: turtle hatching observation with co-partner Sea Sense; a whale watching excursion; sighting hippos on the North of the Island; bird watching walks with a local guide; and beach cleans with the local community."

Take your specialism to the next level

The interaction between people and the planet, our oceans and marine life is an increasingly complex issue, and the question of how to manage our environment presents a global challenge. One that our Postgraduate Students are determined to solve.

Our curriculum constantly adapts to the latest findings in the field, exploring topics like tropical marine oceans, coral reefs, seagrass beds, and mangrove systems. You'll delve into the roles of photosynthetic producers and heterotrophic consumers, understanding ecological processes in tropical marine ecosystems. Additionally, you'll study a career-focused module hones discipline-specific skills, fostering critical analysis, integration, and communication in multidisciplinary research environments.

We offer two standard 1 year courses at Postgraduate Taught level

In addition to this, if you are interested in progressing to PhD level, we also provide a four- or seven-year Integrated PhD in Tropical Marine Biology, in which your first year will be studying at Masters-level, followed by a full- or part-time PhD - giving you a direct route into PhD research study and education.

Why study here?
  • Our Coral Reef Research Unit is the most extensive of its kind in the UK and has study sites across the world's oceans in the Pacific, Indian and Atlantic Ocean.
  • You'll have the chance to network, and be taught by internationally recognised researchers at the forefront of their field, conducting world-changing research across the globe.
  • Our unique multidisciplinary course is designed to deliver advanced theory and facilitate the development of a range of practical and professional skills.

"My postgraduate degree included a 'professional skills' module which was really useful for gaining skills that you might need in academia. It also covered statistics and coding in R, which are great transferable skills for any career in science. Since finishing my degree, I have been running a marine conservation non-profit (set up by myself and a peer from my course) called The Marine Diaries. I also started working as an Environmental Consultant for Orbis Engery, my role involves map creation in ArcGIS, report writing and research."

"When I applied, only two universities in the world were offering PhDs in marine biology on my dream topic: the underwater sounds of coral reefs. Studying at Essex offered me the once-in-a-lifetime chance to study on pristine coral reefs in Indonesia, some of the richest and most diverse coral reefs in the world. I had absolutely no doubt it was the right decision. I am now a Senior Scientific Adviser at Defra, working with policy makers to solve some of the UK's biggest environmental challenges."
