On our marine biology course you dive into a fascinatingly complex world of whales, coral reefs, fish, deep sea trenches, coastal lagoons, sea ice, and tropical seagrass beds. The vast majority of life on earth is found under the sea; but exactly how much remains unknown, since there is so much still to be explored.
At Essex, we take you on a journey of discovery from the poles to the tropical reef systems of the Pacific, Indian and Atlantic Oceans. We work on ecosystems from estuaries and coastal environments to oceanic systems, and on conservation and resource management.
You gain an expert knowledge of marine biology through study of essential core modules and the flexibility to specialise in the areas that interest you most, including:
The major types of marine communities, including aquatic mammals and fish
Direct and indirect human impact on the marine environment
Coral reefs, seagrass beds and mangrove systems
Marine and freshwater taxonomy and biodiversity
Diving and snorkel-based practices
Your independent research project allows you to develop your own interests. Previous topics have included shellfisheries and water quality, turtle ecology in Greece and coral reef conservation strategies in the Caribbean and Indonesia.
There are numerous opportunities to go on field trips as part of this course, although please note that these may be subject to additional costs. These are provided against the relevant modules under the "Structure" tab.
During the field trip to Wakatobi Marine National Park in Indonesia, our students are able to participate in underwater lectures:
Why we're great.

100% of our Marine Biology students expressed overall satisfaction with their course (NSS 2020).
Study abroad
Your education extends beyond the university campus. We support you in expanding your education through offering the opportunity to spend a year or a term studying abroad at one of our partner universities. The four-year version of our degree allows you to spend the third year abroad or employed on a placement abroad, while otherwise remaining identical to the three-year course.
Studying abroad allows you to experience other cultures and languages, to broaden your degree socially and academically, and to demonstrate to employers that you are mature, adaptable, and organised.
If you spend a full year abroad you'll only pay 15% of your usual tuition fee to Essex for that year. You won't pay any tuition fees to your host university
Placement year
Alternatively, you can spend your third year on a placement year with an external organisation. This is usually focussed around your course, and enables you to learn about a particular sector, company or job role, apply your academic knowledge in a practical working environment, and receive inspiration for future career pathways.
If you complete a placement year you'll only pay 20% of your usual tuition fee to Essex for that year.

The aim of this module is to provide a view of how a fundamental understanding of plant processes can impact on the production of plants for the 21st century. Learn the essential processes and constraints on plant growth and development, and explore how innovative technological approaches in plant sciences may provide real solutions to our future predicted global food shortage. You’ll look into key aspects of plant physiology such as different photosynthetic mechanisms, and modern approaches to manipulating plant performance and growth.
Estuarine and Coastal Ecology Field Module (Assessed in Following Year)
This module concentrates on the relationship between biological diversity, and aspects of water chemistry and habitat structure in different coastal environments situated along an estuarine gradient. We will be using the Colne / Blackwater estuary complex as our field site.
Human activity is resulting in an ever-accelerating rate of extinction of biodiversity. Many species in the tropics are becoming extinct even before they have been described by science, while many more are threatened worldwide, including in the UK. Considering the need for biodiversity conservation, you work alongside some of the key employers in the sector including Essex Wildlife Trust and the Environment Agency. Topics include sustainable fisheries and agriculture, climate change, environmental law and captive breeding and re-introduction.
You’ll gain an insight into biology and ecology of tropical coral reef systems. By explaining the nature of the connection between coral reefs and tropical biomes, we help you gain a thorough understanding of the ecological functioning of coral reef systems. We explore the biology of coral reef systems, the landscape ecology of tropical coastal marine systems and examine the importance of the threats to these systems and the options for management.
Coral reefs are overexploited, threatened by multiple anthropogenic stressors and in need of protection through appropriate management. Develop practical skills in coral reef monitoring, assessment and research. Receive training in scuba diving, species identification, and scuba- and snorkel-based assessment and monitoring techniques. Learn how to design, implement and report on scientifically robust underwater research. You have the opportunity to undertake a speciality field-course and can be awarded a Coral Reef Research diver certification from the Profession Association of Diving Instructors (PADI).
