Earth & Environmental Sciences Theses
Earth Sciences at St Andrews dates to the 17th Century, a rich tradition that shapes our vision for the future: to define the cutting edge of Earth, environmental, and planetary science, and deliver unparalleled student education.
Our research is both curiosity driven, addressing profound questions about the co-evolution of Earth and life, and applied, delivering societal and economic impact. It spans recent environmental change to planetary formation, underpinned by state-of-the-art analytical and field capabilities.
