“Studying at St Andrews has given me much more than just an education. It has instantly given me the feeling of home and it never ceases to amaze me how much the University cares about the wellbeing of the students. Thanks to the flexibility of the schedules, I was able to engage in other sciences beside biology in the first year, and explore different aspects of the subject in the second year.”

Course details

The MMarBiol in Marine Biology is a five-year Integrated Masters course run by the School of Biology. Students are provided with high-tech equipment, laboratories and expertise to facilitate learning and to develop the skillset of a modern marine biologist. 

In the first three years of your degree, you will take the core modules in biology along with modules intended to prepare you for advanced modules in Marine Biology specifically.   

Alongside biology, in the first year of your studies you will be required to study an additional two subjects. In the second year, you will usually carry on at least one of these subjects, sometimes two. Find out more about how academic years are organised. 

In third year, there is a shift from core, broad-themed modules to more specialised modules that allow students to prepare for their Honours degree. 

In your fourth year, students undertake a year-long research placement in a research institute or in industry away from St Andrews, along with an online module on experimental design. 

The fifth and final year of the Masters degree involves highly specialised taught courses in your chosen speciality and a final- year project and dissertation. 

Centres of research within the School of Biology offer students the experience of working alongside experts and the opportunity to develop their own research in Honours years. 

These facilities include:

  • The Scottish Oceans Institute houses a modern aquarium and laboratories for molecular, developmental and physiological studies of marine systems. The institute is ideally placed on the seashore near sandy and rocky shore ecosystems, grey and common seal colonies, and bottlenose dolphin feeding areas. 
  • The Centre for Biological Diversity has excellent facilities for behavioural, ecological and evolutionary research on animals (including birds and insects) and plants. Many members of the CBD also run active field studies as part of their research, allowing access to field-based projects as well as laboratory studies.
  • The Biomedical Sciences Research Complex offers large multi-group laboratories that are focused on structural biology, molecular microbiology, virology, chemical biology, cell biology and molecular medicine. 

The University of St Andrews operates on a flexible modular degree system by which degrees are obtained through the accumulation of credits. More information on the structure of the modules system can be found on the flexible degree structure web page.

Modules

In the first two years of your degree (known as Sub-Honours), you will take the compulsory modules in biology alongside modules in at least one other subject. 

Typically, you will take core modules during your first two years, and advanced modules during your third, fourth and fifth years (known as Honours).

In first year, modules introduce you to core subject material relevant to all biology degree programmes. Both of the following modules are compulsory. 

  • Biology 1: provides an introduction to molecular and cellular biology. It covers cell diversity and the origins of life, evolution, cellular structures and fundamental processes. 
  • Biology 2: provides an introduction to the diversity of life on Earth and addresses key elements of organismal, behavioural and ecological aspects of life.

In second year, modules are chosen which will best prepare you for Marine Biology, and new topics are introduced in some second-year modules. Students on the Marine Biology Masters course must take the following modules: 

  • Ecology: introduces essential concepts in population and community ecology and how they relate to biodiversity. 
  • Research Methods in Biology: develops essential academic and transferable skills, with major emphasis on problem solving. This is achieved through a combination of interactive lectures, independent data-handling workshops and group work on a mini research project. 
  • The Oceans: introduces basic concepts in biological and physical oceanography, and provides an understanding of how physical processes such as circulation patterns, waves and tides affect plants and animals living in the different ocean biomes. 

Students must also take one of the following modules: 

  • Invertebrate Zoology: surveys the major invertebrate groups, emphasising the diversity of body plans while demonstrating how the common functional requirements such as feeding, reproduction, respiration and excretion are achieved. 
  • Vertebrate Zoology: explores the diversity of vertebrate animals, providing a detailed look at the defining characteristics of the body plans and lifestyles of the key vertebrate group.

In third year, you will continue to specialise in Marine Biology via a wider range of modules covering core topics. Modules that have been offered in previous years include:

  • Biology of Marine Organisms 
  • Ecosystems and Conservation
  • Evolution
  • Field Course 
  • Methods in Aquatic Biology
  • Statistical and Quantitative Skills for Biologists

Students will also take two further modules. Modules that have been offered in previous years include:  

  • Animal Behaviour: A Quantitative Approach  
  • Co-evolution: Living Together 
  • Genes, Cells and Development

In fourth year, students typically undertake an independent 7 to 12-month research placement hosted by an external institute or company. The external placement gives students the opportunity to practise and learn a range of scientific and generic skills, including an element of independent research working outside of St Andrews, and an online module on experimental design. 

During your fifth year you will undertake an Advanced Research Project, and will complete the core module Advanced Topics in Biology. You will also take research-led modules in your chosen speciality. Advanced modules offered in the past include: 

  • Environmental Drivers of Marine Habitats 
  • Fisheries Research  
  • Foraging in Marine Mammals
  • Marine Mammals and Humans
  • Scientific Diving 
  • Tropical Marine Biology
  • Biological Oceanography

The modules above are examples of what has been taught in previous academic years and may be subject to change before you start your course. Please see the module catalogue for more details of each module, including weekly contact hours, teaching methods and assessment.

Teaching

The MMarBiol is taught through a combination of: 

  • lectures 
  • seminars 
  • tutorials 
  • practical classes 
  • field work 
  • research projects

Alongside the development of practical biological skills, students are also given the opportunity to expand on their presentation and IT skills. 

Typical class sizes include: 

  • First year: lectures 250 to 300 students, practicals 80 to 100 students 
  • Second year: lectures 80 to 175 students, practicals 40 to 60 students 
  • Third year: lectures 20 to 140 students, practicals 20 to 60 students 
  • Fourth and fifth year: 5 to 25 students per module

When not attending lectures, tutorials and labs, you will be expected to continue learning independently through self-study. Typically, this will involve: 

  • working on individual and group projects 
  • undertaking research in the library or in PC classrooms 
  • preparing coursework assignments and presentations 
  • preparing for examinations

During first year, Biology modules are entirely assessed by coursework.

During second and third year, most modules are assessed by an equal weighting of coursework and written examinations. 

In fourth and fifth year, most modules are entirely assessed by coursework, while some include written examinations in addition to coursework. 

During the external placement in fourth year, you will be assessed jointly by the immediate supervisor in your host institute or company and a member of staff in the School of Biology. 

The School of Biology aims to provide feedback on every assessment within three weeks to help you improve on future assessments. 

Undergraduates at the University of St Andrews must achieve at least 7.0 on the St Andrews 20-point grade scale to pass a module. To gain access to Honours-level modules, students must achieve the relevant requisites as specified in the policy on entry to Honours and in the relevant programme requirements. To find out the classification equivalent of points, please see the common reporting scale.

You will be taught by leading researchers in the field with an emphasis on research-led teaching. Postgraduate research students who have undertaken appropriate training may also contribute to the teaching of laboratory classes and seminars under the supervision of the module leader.
