Introduction

Do you like sciences but have a hard time choosing which one to pursue? Can you picture yourself performing experiments in the lab, or collecting data in the field, or developing and testing models on a computer? Then Earth Sciences is the discipline for you. It is the study of physical, chemical, and biological processes over a wide range of temporal and spatial scales in earth and planetary systems. 

Our department offers various programs:

   The three specialist programs – Geology, Environmental Geoscience, and Geophysics (offered in collaboration with the Department of Physics) – give students the skills to enter graduate studies and also allows them to become professional “geoscientists in training” after graduation. The Geology specialist program focuses on processes of the solid planetary bodies, including volcanoes, sedimentary environments, mountain building, the formation of minerals or ores, and Earth through time. The Environmental Geosciences specialist program in addition addresses processes related to groundwater and biochemical activities. The Geophysics specialist program allows students to model physical processes in and on Earth and other planets and to apply non-invasive methods of imaging the subsurface, often in 4D (i.e., space and time); targets may range from archaeological investigations to groundwater imaging and mineral exploration, but also include modeling of mountain-building processes and planetary magnetic fields.

   The Geoscience Major program builds on a set of core courses and allows students to select elective courses that match their particular interests. Students have paired this program not just with other science programs but such diverse fields as geography, archaeology, economics, history, political science, or peace and conflict studies. 

   The Geoscience Minor program provides an introduction to Earth science topics and thinking. 

   The new major called “Earth and Environmental Systems” takes a holistic approach to understanding how the Earth system works and how it has evolved over tens to millions and billions of years. This requires understanding the dynamics and interactions of all aspects of the system (solid Earth, ocean, atmosphere, and biosphere) and provides the larger context at a time when climate change, resource consumption and global pollution weigh heavily on people and societies.
