The "Earth System Science (ESS)" Graduate Program (M.S. and Ph.D.) addresses the growing national, regional, and global demand for trained professionals in Earth System Science and its applications. ESS is an interdisciplinary program aiming to explore, understand and teach the Earth, its relevant complex processes, past and future evolution, and its interactions with society. The program emphasizes a research-oriented, global systems approach to study the atmosphere, hydrosphere, and lithosphere, including their interrelationships and interactions with the biosphere. Emphasis is on the observation and quantitative analysis of the Earth system with human inflicted problems. Students completing the program will be qualified to pursue careers that require knowledge of the basics of Earth system science and the requisite tools.
