The Department of Earth Sciences includes a spectrum of disciplines focused on understanding the processes that influence the tectonics and environment of the planet, on using this understanding to read the record of earth history written in rocks and sediments, and on developing models that can be used to predict future changes due to natural phenomena and mankind's perturbations. Issues of societal concern related to seismic risk, climate change, environmental contamination and other geologic hazards play an important role. Sub-disciplines housed in the department include geophysics, geochemistry, structural geology, petrology, marine geology, sedimentology, physical and chemical oceanography, paleoceanography and paleontology. In recognition of the growing diversity of its programs, the department has recently changed its name from Geological Sciences to Earth Sciences. The department is committed to emphasizing both educational and research programs and views these efforts as complementary.
Instruction is offered on several levels.
These include introductory classes for non-science majors, undergraduate courses that are appropriate for undergraduates majoring in earth sciences or other science and engineering disciplines, and graduate classes appropriate for advanced degrees. A close working relationship exists between students and faculty members. Classes beyond the introductory level are usually small, permitting personalized instruction. Field trips are an important part of the instructional program. The graduate program is closely linked with these research efforts, and both graduate and undergraduate students participate in research projects.
