The Department of Earth Sciences offers programs of study leading to the following degrees: bachelor of science in geology; bachelor of science in meteorology; bachelor of science in oceanography; bachelor of arts in the earth sciences and bachelor of science in education (B.S. Ed.) in earth sciences with secondary education certification. Oceanography majors must select one of the following options: biological oceanography, chemical oceanography, geological oceanography or physical oceanography. Geology majors may choose options in sedimentary/surficial geology, geochemistry, geophysics or engineering geology.

The bachelor of science programs in meteorology, geology and oceanography are intended to prepare students for admission to graduate school or for professional employment upon graduation.

The bachelor of arts degree in earth sciences is designed to meet the needs of students who want exposure to all of the earth sciences but who do not intend to continue their studies in a particular academic area. However, by selecting additional appropriate courses as electives, it is possible for these graduates to meet the admission requirements of graduate schools in one of the earth sciences or to prepare for employment in an earth science field.

The program leading to the bachelor of science degree in education in earth sciences with secondary education certification prepares students for teaching careers in the secondary schools. The core of the curriculum provides a sound education in the traditional earth sciences areas of oceanography, meteorology, geology, and astronomy. Completion of this curriculum leads to certification in earth and space science. In addition, graduates may teach general science.

Cooperative education programs in the earth sciences provide opportunities for majors to apply knowledge gained in the classroom to the challenges of professional employment.

Millersville University is a member of the Marine Science Consortium, and the earth sciences department actively participates in this program. Several oceanography courses are available through the Consortium. In particular, one course required in the oceanography major (Field Methods in Oceanography) must be taken through the Consortium at Wallops Island, Virginia. For more information see "Marine Science Consortium" in the Special Academic Opportunities section.

The Department of Earth Sciences is an academic affiliate in the University Corporation for Atmospheric Research, and a corporate member of the American Meteorological Society.
