EAPS Facts

The Department of Earth, Atmospheric, and Planetary Sciences is dedicated to the scientific study of the physical, chemical, and dynamical processes that range from such seemingly diverse topics as plate tectonics to asteroid impacts to tornadoes. EAPS is a multidisciplinary department of the College of Science, requiring the use of mathematics, physics, chemistry, statistics, and computer sciences to research problems; along with state of the art computer and laboratory facilities for calculation, visualization, and experimentation.

The mission of EAPS is to serve the citizens of Indiana, the United States, and the world through discovery that expands the realm of knowledge in basic and applied Earth, atmospheric, planetary and interdisciplinary sciences, learning through education and the dissemination of scientific knowledge, and engagement through the exchange of scientific skills and understanding.

Since 1988, the department has occupied a portion of the six-story addition to the Hampton Hall of Civil Engineering. EAPS occupies limited space on the ground floor, all of the 2nd, 3rd, and 4th floors, and a rooftop observatory with access to rooftop instrumentation platforms. In total, EAPS has 50,449 square feet in the building divided into research labs (48%), teaching facilities (14%), and support operations (38%). Additionally, the Physics Building, houses the EAPS Rock Sample Processing and Research Facility.

The EAPS library is located in the Hampton Building and contains 36,336 monographs and bound journal volumes, 203,000 maps, and an aerial photograph collection. The collections and services of the EAPS Library are available to the entire university community, though this library primarily supports the research and instructional activities of the Department of the Earth, Atmospheric, and Planetary Sciences' faculty, students, and staff.
