Bachelor of Science (Earth and Ocean Sciences)

The Bachelor of Science (Earth and Ocean Sciences) at University of Galway is a four-year honours undergraduate degree that explores the interconnected dynamics of the Earth’s structure, history and processes together with the physical, chemical and biological workings of the oceans, equipping students to understand global change, natural hazards and sustainable management of Earth systems. It suits students who are passionate about geoscience, oceanography, climate systems, environmental fieldwork and research-driven solutions to pressing planetary challenges such as climate change, natural resource sustainability and coastal processes.

Curriculum structure

Year 1 – Foundational Earth & Ocean Sciences:

In Year 1, students begin with core modules such as Earth & Ocean Sciences for Society, The Earth: From Core to Crust, Biology, Chemistry and Physics that introduce the basic principles of the Earth’s structure, surface systems and oceans alongside fundamental natural science. This foundation provides an integrated scientific perspective on how geological and oceanic processes shape and sustain the planet. Practical laboratories and introductory lectures build essential research, analytical and fieldwork skills.

Year 2 – Introducing Oceanography and Earth Processes:

In Year 2, students move into more focused topics including Introduction to Ocean Science, Earth Surface Landforms & Processes, as well as modules in Zoology and Botany & Plant Sciences, supported by Scientific Writing Skills and Field Skills. This year strengthens observational and data-collection skills while expanding understanding of surface geology, coastal environments and biological components of Earth systems.

Year 3 – Applied Earth and Ocean Science Techniques:

The third year integrates advanced Earth and ocean science modules such as Geological Structures and Maps, Physical Oceanography, Sediments and the Sedimentary Record, Palaeontology and Evolution, Minerals, Magmas and Metamorphism, and Hydrology, as well as Environmental and Marine Geophysical Remote Sensing and Applied Field Hydrology. Students gain hands-on experience through field trips and geological mapping while learning to analyse physical and chemical systems across terrestrial and marine environments.

Year 4 – Advanced Research & Specialist Exploration:

In the final year, students deepen their expertise with modules such as Global Change, Advanced Fieldskills and Earth Observation and Remote Sensing, and choose from advanced options such as History of Life, Economic Geology, Biophysical Interactions in the Ocean or Applied Field Hydrogeology alongside a Final Year Project. This year emphasizes independent research capability, advanced fieldwork — including potential ship-based oceanographic field skills — and interdisciplinary understanding of Earth-ocean linkages.
