This International Marine Science course offers students with a background in marine biology, geology or geography the opportunity to integrate their expertise in the wider marine science context.

The highly interdisciplinary field of Marine Science aims to understand the biology, chemistry, geology and physics of this dynamic system so central to all our lives. It also considers the overarching influence of climate change and how policy can be brought to bear on managing the resources of the ocean as part of the Blue Economy.

The course has two mandatory courses in Oceanography and GIS for Marine and Environmental Scientists, and offers a wide variety of options with maximum flexibility, allowing students to pursue their studies according to their academic interests.

This course also offers students incredible opportunities during their MSc to work extensively with academics in active research groups, often leading to co-authorship on peer-reviewed publications. There are also fieldwork opportunities to Malaysia through the optional Tropical Coral Reefs: Monitoring and Management course which involves a involves a two-week field trip to Malaysia where students are given the opportunity to explore the marine environment whilst learning different techniques for surveying and monitoring coral reefs. Watch our tropical coral reef monitoring video from a recent trip to Bidong Island in Malaysia.

Semester 1 


This course introduces the fundamentals of oceanography, providing an essential foundation at the beginning of the course for students who either do not have a background in the subject area, or whose background is largely limited to marine biology

Applied Research Design and Analysis

The aim of this course is to enable the student to effectively plan and design research and survey projects, devise a sound experimental design, analyse and present data in a rigorous scientific manner. In particular, this course will provide MSc students with an understanding of the theoretical basis of scientific method and with training in the general skills needed for planning a scientific research project. Students will learn about scientific method, experimental design, testing hypothesis, simple data analyses and data presentation, and the legal and ethical principles involved in scientific research. Students will develop skills in simple quantitative statistical methods needed for research projects.

Semester 2

GIS for Marine and Environmental Scientists

The aim of this course is to provide students with a substantial introduction to geographical information systems so that you will be able to understand the theoretical background to GIS and be able to make practical use of a widely used GIS program.

Semester 3


This research project allows you to focus on a specific area of interest, with opportunities to collaborate with businesses and other stakeholders. You choose your dissertation subject, in discussion with your supervisor.


Our Marine Environment and Climate Change programmes prepare our graduates for a career in Marine Environmental Consultancy, Basic Research and Marine Conservation. Employers include Industry, Government Agencies, Universities and NGOs. 

Most recent graduate career moves:

  • Lucy Grindall (2019) is now an environmental Specialist with Genesis Oil & Gas.
  • Georgia Waldram (2019) Has commenced a PhD with Dr Tony Gutierrez at Heriot-Watt University

The International Marine Science MSc takes this approach a step further and will equip our graduates with the skills to operate on an international stage, as marine environmental issues increasingly require attention on a global scale.
