Bachelor of Science (Marine Science)
Marine Science encompasses the study of marine life and environments, how they are formed and evolve, and how they are affected by human activity. Topics covered in this programme include marine biology, earth science, chemistry and experimental physics, mathematics, statistics, oceanography, meteorology, botany, geology and microbiology.
The degree in Marine Science is a four-year degree leading to a BSc (Hons). At the end of the degree, you will have improved your knowledge about the marine environment and will have developed your thinking and practical and personal skills, enabling you to undergo further academic training in a wide variety of scientific disciplines or begin your career. Marine Science is a broad area and the programme aims to help you find what speciality you prefer to study by introducing the subject in a general way at first and allowing you to follow your particular interests later on.
At present, University of Galway is the only Irish university offering this degree programme and it now has the highest concentration of marine scientists of any institution in Ireland. Research ranges from fundamental understanding of the marine ecosystem to very applied activities involving close co-operation with industry and state agencies. The 3,000 square metre Martin Ryan Marine Science Institute houses most of the teaching and research activity in Marine Sciences at the university. MRI Carna carries out applied research in Carna, County Galway.

Mode of study
This year is a foundation year to ensure that all students have the background needed for more advanced material. The staff teaching science subjects (Biology, Chemistry, Physics) will not assume that all the class have studied the subject in their school-leaving qualification. There are additional supports to help students like SUMS - the mathematics support centre at University of Galway.
Students are able to select from a range of appropriate science modules, alongside core marine material in modules like Fundamentals in Aquatic Plant Science, Introduction to Ocean Science and Invertebrate Zoology (many invertebrate groups are exclusively or mostly marine).
This year continues the balance of core (e.g., Marine Habitat) and optional modules. This is also the year where it is possible to participate in an Erasmus exchange or apply for one of the College of Science and Engineering’s study abroad opportunities).
The 4th year includes a major research project carried out with an academic supervisor. This helps develop deeper knowledge alongside skills in project management and data evaluation. Also in this year there is a module (Field Skills in Marine Science) structured around experience on one of the Marine Institute’s research vessels. There is a free choice of optional modules, including a module in ocean politics.

Glossary of Terms
- You must earn a defined number of credits (aka ECTS) to complete each year of your course. You do this by taking all of its required modules as well as the correct number of optional modules to obtain that year's total number of credits.
- An examinable portion of a subject or course, for which you attend lectures and/or tutorials and carry out assignments. E.g. Algebra and Calculus could be modules within the subject Mathematics. Each module has a unique module code eg. MA140.
- Some courses allow you to choose subjects, where related modules are grouped together. Subjects have their own required number of credits, so you must take all that subject's required modules and may also need to obtain the remainder of the subject's total credits by choosing from its available optional modules.
- A module you may choose to study.
- A module that you must study if you choose this course (or subject).
- Required Core Subject
- A subject you must study because it's integral to that course.
- Most courses have 2 semesters (aka terms) per year, so a three-year course will have six semesters in total. For clarity, this page will refer to the first semester of year 2 as 'Semester 3'.

What Our Students Say
Alina Madita Wieczorek | 4th Year Marine Science
I moved from Germany to Galway to study Marine Science as I wanted to study in English and as close to the Atlantic as possible. The first year of the course focused on giving the same background knowledge to all students. During the second and third year I gained in-depth knowledge in many different areas of Marine Science as the course is truly multidisciplinary. I more and more realise now that this is one of the more important if not the most important aspect of my studies in Univerisity of Galway as it enables me to link up topics from different areas such as how ocean physics influence the biology of our oceans. My favourite part of the degree was the research project in year four where the lecturers hand over to you. In this period I picked up many valuable skills, which are of great help to me now. At the moment I am doing a bursary in the Marine Institute. I hope in the future to do research around marine environmental issues and acquire a PhD in this area.
