Geophysical Sciences

Departmental Counselor: Douglas R. MacAyeal, HGS 413, 702-8027
Departmental Office: HGS 161, 702-8101

Program of Study

The Department of the Geophysical Sciences offers unique programs for students who wish to study broad problems of the earth and the solar system. These problems include the physics, chemistry, and dynamics of the atmosphere, oceans, and ice sheets; 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 of life through geologic time. They require modern methods of study founded on the basic sciences of mathematics, physics, chemistry, and biology.

Program Requirements

With proper choice of electives, the degree of Bachelor of Arts with concentration in the geophysical sciences is the normal avenue of approach to graduate work in the department or in other institutions in which geophysics is broadly conceived. The program of study is based upon fundamental courses in the basic sciences, followed by more specialized courses in the geophysical sciences. The core of the program is the introductory sequence, Geophysical Sciences 131-132-133. This one-year course serves a twofold purpose. It presents a unified picture of the earth as seen by modern methods of exploration, and it prepares students for further study in the geophysical sciences. Students interested in taking this sequence should check with the departmental counselor. Students may also enter the program by substituting Physical Sciences 108-109-110 (grade of B or better) for Geophysical Sciences 131-132-133.

Degree Programs.
Several different degree programs have been developed by the Department of the Geophysical Sciences. Four of these programs provide a strong background in the geophysical sciences with special emphasis on (1) mineralogy, petrology, and geochemistry; (2) meteorology, oceanography, and climate dynamics; (3) paleontology and stratigraphy; or (4) solid earth geophysics. Another program offers a broad exposure to the geophysical sciences. Certain areas of the geophysical sciences require a strong background in chemistry, physics, or mathematics. For this reason, students are encouraged to consult with the departmental counselor to develop strong degree programs through the wise use of electives. In addition to consulting the departmental counselor, interested students should examine the Student Handbook of the Department of the Geophysical Sciences.

Students planning to concentrate in the geophysical sciences should take Chemistry 111-112-113 or higher in their first year to satisfy the Common Core requirement in the physical sciences. Geophysical Sciences 131-132-133, usually taken in the second year along with Physics 121-122-123 (General Physics) or higher, is the normal entry into the concentration program, although qualified students (to be determined by the departmental counselor) may begin their study in this area at the 200 level. There are several paths to the bachelor's degree in geophysical sciences. Careful planning is essential because nine courses in geophysical sciences are required for this degree. Due to the complexity of program requirements, all students interested in concentrating in the geophysical sciences should consult the departmental counselor during their first and second years in the College to discuss their programs and to insure that all prerequisites are satisfied.

B.A. with Honors.
The B.A. with honors is awarded to students who meet the following requirements: (1) B average (3.0) in all Physical Sciences Collegiate Division courses, excluding free electives, (2) completion of at least three advanced (300-level) courses drawn from the graduate programs of the Biological and Physical Sciences divisions in consultation with departmental counselor, and (3) completion of an honors paper. Selection of the three advanced science courses must be approved by the departmental counselor.

Cross-Listed Courses.
When a course is cross-listed in geophysical sciences and some other department, that course will be counted, for degree purposes, as a course in geophysical sciences.

Field Trips and Courses.
The department normally sponsors about twelve trips each year, ranging in length from one day to one month and including areas as far afield as Newfoundland, the Caribbean, and California. Most of these trips are designed as undergraduate field courses--Geophysical Sciences 228, 229, 230, and 240--or are run in connection with undergraduate lecture courses--for example, Geophysical Sciences 131--but all students and faculty are welcome to participate if there is room.

Grading.
Subject to College and divisional regulations, and with the consent of the instructor, all geophysical sciences concentrators may register either for regular letter grades or for P/N or P/F grades in any course used in the concentration. Geophysical science courses taken by nonconcentrators may also be taken P/N or P/F, subject to the same constraints. A Pass may be given for work of D quality or better. Any grade conferring course credit may be counted toward the minimum grade point average of 2.0 required for the concentration at the time of graduation.

Sample Program.
The following sample schedule highlights the importance of an early introduction to the fundamentals of mathematics, physics, and chemistry. Classes in geophysical sciences are normally begun during the second year (although exceptions can be made). Geophysical sciences electives, taken in the third and fourth years, include paleontology, sediments and sedimentary rocks, meteorology, oceanography, solid earth geophysics, and field courses. A summer field course (Geophysical Sciences 228) should be taken during the second or third year.
