Bachelor of Science in Geological and Environmental Sciences

The major consists of five interrelated components:

  1. Earth Sciences Fundamentals—Students must complete a set of core courses that introduce the properties of Earth materials, the processes that change the Earth, and the timescales over which those processes act. These courses provide a broad foundational knowledge that can lead to specialization in many different disciplines of the geological and environmental sciences.
  2. Quantitative and Analytical Skills—Students must complete adequate course work in mathematics, chemistry, and physics or biology. In addition, they learn analytical techniques specific to the Earth sciences through the laboratory component of courses.
  3. Advanced Course Work and Research—Students gain breadth and depth in upper-level electives and are encouraged to apply these skills and knowledge to problems in the Earth sciences through directed research.
  4. Field Research Skills—Most GES courses include field trips and/or field-based projects. In addition, students must complete at least six weeks of field research through departmental offerings or through a faculty-directed field research project that involves learning and application of field techniques, field mapping, and the preparation of a written report.
  5. Communication Skills—To fulfill the Writing in the Major requirement, students take a writing-intensive senior seminar (GES 150), in which they give both oral and written presentations that address current research in the earth sciences.

The major requires at least 80 units; letter grades are required in all courses if available. Students interested in the GES major should consult with the undergraduate program coordinator for information about options within the curriculum.

Additional courses in Geophysics, EESS, and ERE may be counted towards the elective units if they allow a student to pursue a topic in depth; these options should be discussed with an adviser. A maximum of 3 elective units may be fulfilled by GES 192, 197, 198, or advanced seminars. Honors research (GES 199) may fulfill up to 4 elective units.

FIELD RESEARCH

Field research skills are a critical component of the undergraduate curriculum in GES. The conventional and most straightforward way for undergraduates to meet the field requirement is to take the two GES courses (GES 105 and GES 190) that are offered every year:

By taking GES 105 and two iterations of GES 190, GES undergraduates develop the broad experience and confidence necessary to go out and evaluate a geological or environmental geology question by collecting field-based data. The main goal is that, upon graduation, GES undergraduates will be able to plan and execute independent field research.

It is also possible to customize GES 190 or substitute non-Stanford courses to allow flexibility in fulfilling the field requirement. One or two GES 190 requirements can be satisfied through customized courses with two possible approaches:

  1. The first approach involves working on a project during the summer with a graduate student or professor. This may fulfill one GES 190 requirement. To receive credit for GES 190, a proposal must be filed at the end of Winter Quarter with the field program committee which evaluates it for suitability.
  2. A second approach is to take a modified version of an existing field-based course such as Stanford at Sea/Australia/Hawaii. This may also fulfill one GES 190 requirement.

In both cases, to receive credit for GES 190, a proposal must be filed at the end of Winter Quarter with the field program committee which evaluates it for suitability. Students subsequently enroll in GES 190 with a specific instructor or their faculty mentor who evaluates the final report from the fieldwork.

GES 190 can also be satisfied by enrolling in a single four-to-six week geology field camp offered by another institution. This externally administered experience can substitute for two GES 190 courses, subject to approval by the Undergraduate Curriculum Committee.

COGNATE COURSES

Many courses offered within the School of Earth Sciences, as well as courses in other schools with a significant Earth sciences component, may be used in satisfaction of optional requirements for the Geological and Environmental Sciences degree. Undergraduates should discuss the options available to them with the undergraduate program coordinator; graduate students should discuss options with their advisers.

The following courses outside the School of Earth Sciences are particularly applicable:

HONORS PROGRAM

The honors program provides an opportunity for year-long independent study and research on a topic of special interest, culminating in a written thesis. Students select research topics in consultation with the faculty adviser of their choosing. Research undertaken for the honors program may be of a theoretical, field, or experimental nature, or a combination of these approaches. The honors program is open to students with a GPA of at least 3.5 in GES courses and 3.0 in all University course work. Modest financial support is available from several sources to help defray laboratory and field expenses incurred in conjunction with honors research. Interested students must submit an application, including a research proposal, to the department by the end of their junior year.

Upon approval of the research proposal and entrance to the program, course credit for the honors research project and thesis preparation is assigned by the student's faculty adviser within the framework of GES 199; the student must complete a total of 9 units over the course of the senior year. Up to 4 units of GES 199 may be counted towards the elective requirement, but cannot be used as a substitute for regularly required courses.

Both a written and oral presentation of research results are required. The thesis must be read, approved, and signed by the student's faculty adviser and a second member of the faculty. In addition, honors students must participate in the GES Honors Symposium in which they present their research to the broader community. Honors students in GES are also eligible for the Firestone medal, awarded by Undergraduate Advising and Research for exceptional theses.
