Studying Earth and Ocean Sciences

Course overview

Earth and Ocean Sciences involve the study of the physical and chemical processes that affect planet Earth and its oceans. In this field, you will study topical subjects, such as climate change, natural resources and the management and conservation of our oceans. Four sub-disciplines are involved: geology, geophysics, hydrogeology and oceanography, which, in different ways, look at various workings of our planet, from the atmosphere to the seabed.

Earth and Ocean Sciences subjects are your ticket to a global career market. They offer the opportunity to study some of the most exciting areas in the natural sciences while being able to see at first hand their practical relevance in the world around you.

"..I chose NUI Galway because of the great choice of subjects available through my degree. No other university offers such flexibility for students in this subject area. This becomes increasingly important as you develop during your third level education. There is great interaction between staff and students at NUI Galway. I would definitely encourage those with an interest in science or natural sciences to pursue this course. The standard of education offered here is of the highest quality..."
