Requirements for the Degree—A minimum of 135 units of graduatestudy at Stanford must be satisfactorily completed. An acceptable programnormally consists of at least 45 lecture units in the areas listed following.Up to 18 lecture units in categories 2, 4, and 6 may be satisfied by coursestaken elsewhere if the previous course duplicates an existing Stanfordcourse and the Stanford faculty member responsible for the course concurs.Required courses must be taken for a letter grade, if offered. Students arerequired to attend the department seminars.1. ENGR 202W.2. GEOPHYS 201.3. 12 units of Geophysics lecture courses numbered 100 or higher.4. 12 units of Geophysics lecture courses numbered 200 or higher, takenfrom at least four faculty members with different research specializations.5. One 3-unit lecture course numbered 100 or higher in mathematics,science, or engineering covering mathematical methods, continuumor fluid mechanics, or Fourier/spectral analysis.

6. 9 units of 200-level or higher courses in math, science, engineering,or other quantitative science.7. 6 units of non-Geophysics lecture courses numbered 100 or higher inEarth or planetary sciences, ecology, hydrology, chemistry, or relevantbiology.8. One 3-unit non-Geophysics lecture course numbered 200 or higher inEarth or planetary science, ecology, hydrology, chemistry, or relevantbiology.9. Sufficient units of independent work on a research problem to meet the135-unit University requirement. 12 units must be met by participationin the GEOPHYS 385 series, or equivalent series in other departmentswith approval of the adviser and graduate coordinator. Students areencouraged to participate in the GEOPHYS 385 series from more thanone faculty member or group and relevant equivalent series in otherdepartments.10. Two quarters of quarter-time teaching assistant experience. For moreinformation, see the Geophysics Administrative Guide, section 1.4.1.
