New Mexico Tech's Department of Earth and Environmental Science offers BS, MS, and PhD degrees in a broad range of earth sciences. The department incorporates five strongly interacting graduate programs-- Geology, Geochemistry, Geophysics, Hydrology, and Geobiology -- in association with an integrated undergraduate major in Earth Science featuring options in Environmental Geology, Geochemistry, Geology, Geophysics, and Hydrology. The department also administers a cross-department undergraduate degree in Environmental Science.
The department has 20 faculty members, of which six are in geophysics, four in hydrology, and ten in geology and geochemistry. In addition, the department has 30 affiliated research and adjunct faculty who are actively involved in research and/or teaching. Many of these are from the New Mexico Bureau of Geology and Mineral Resources, which is located on campus, but they also come from industry, national laboratories, and other organizations. The IRIS PASSCAL Instrument Center and EarthScope USArray Array Operations Facility, two major NSF-funded seismological facilities, are also housed on campus and administered by faculty of the geophysics program.
