The Department of the Geophysical Sciences (GEOS) offers unique programs of study in the earth, atmospheric, and planetary sciences. Topics include the physics, chemistry, and dynamics of the atmosphere, oceans, and ice sheets; past and present climate change; the origin and history of the Earth, moon, and meteorites; properties of the deep interior of the Earth and the dynamics of crustal movements; and the evolution and geography of life and the Earth's surface environments through geologic time. These multidisciplinary topics require an integrated approach founded on mathematics, physics, chemistry, and biology.
Both the BA and BS programs prepare students for careers that draw upon the earth, atmospheric, and planetary sciences. However, the BS degree provides a more focused and intensive program of study for students who intend to pursue graduate work in these disciplines. The BA degree also offers thorough study in the geophysical sciences, but it provides a wide opportunity for elective freedom to pursue interdisciplinary interests, such as environmental policy, law, medicine, business, and precollege education.
The principal distinction between the BA and BS programs is the number of 20000-level courses required for the major and their distribution among subdisciplines. Students are advised, but not required, to complete GEOS courses at the 13000 level in their first or second year.
A minimum of six additional 20000-level science courses are required. At least four must be from the Earth Sciences (List A). Up to two may be chosen from Support Courses for the Earth Sciences (List C). Up to two may be chosen from Mathematics and Statistics Courses (List F). One may be a field course.
A minimum of eight additional 20000-level science courses are required. At least three must be from the Geophysical Sciences (List A). Up to three may be chosen from Support Courses for the Geophysical Sciences (List C). Up to two may be from Mathematics and Statistics Courses (List F). One may be a field course. One may be GEOSÂ 29700 Reading and Research in the Geophysical Sciences.
Candidates for the BS in Environmental Science begin their program of study with GEOSÂ 13300 The Atmosphere and GEOSÂ 13400 Global Warming: Understanding the Forecast. Students are strongly encouraged to take these classes before their third year. With prior consent of the departmental counselor, students with the appropriate background may substitute a 20000-level course, which may be taken during or after the third year.
A minimum of four additional 20000-level science courses are required. One must be a GEOS course and one must be a BIOS course chosen from the Environmental Sciences courses (List B). Others may be chosen from Environmental Sciences Courses (List B), Support Courses for the Environmental Sciences (List D), or Mathematics and Statistics Courses (List F). One may be a field course. One may be a GEOSÂ 29700 Reading and Research in the Geophysical Sciences. Three other courses must be chosen from Support Courses for the Environmental Social Sciences (List E). In addition, two other courses must be chosen from Support Courses for Mathematics and Statistics (List F), one of which must be a statistics course.
Students majoring in geophysical sciences must receive quality grades in all courses taken to meet requirements in the major.
The BA or BS degree with honors is awarded to students who meet the following requirements: (1) a GPA of 3.25 or higher in the major and of 3.0 or higher overall; (2) completion of a paper based on original research, supervised and approved by a faculty member in geophysical sciences. GEOSÂ 29700 Reading and Research in the Geophysical Sciences can be devoted to the preparation of the required paper; however, students using this course to meet a requirement in the major must take it for a quality grade. The research paper must be completed by eighth week of the quarter in which the student will graduate.
Students who wish to submit a single paper to meet the honors requirement in geophysical sciences and the BA paper requirement in another major should discuss their proposals with both program chairs no later than the end of third year. Certain requirements must be met. A consent form, to be signed by the chairs, is available from the College adviser. It must be completed and returned to the College adviser by the end of Autumn Quarter of the student's year of graduation.
The department typically sponsors several trips each year that range in length from one day to five weeks. Destinations of trips have included areas as far afield as Newfoundland; the Canadian Rockies; Baja, California; the Caribbean; Italy; and Iceland. The longer trips are designed as undergraduate field courses:
Most of the shorter trips are mostly scheduled in connection with undergraduate and graduate lecture courses. However, the trips are open to all students and faculty if space permits.
Each student will design an individual plan of course work, choosing from a wide range of selections that take advantage of rich offerings from a variety of subdisciplines. The sample programs that appear below are merely for the purpose of illustration; many other variations would be possible. NOTE: Courses that meet general education requirements and are required for the major are not listed.
