Geological and Planetary Sciences (GPS) (Geology, Geobiology, Geochemistry, Geophysics, Planetary Science) and Minor

The aim of the undergraduate program is to provide thorough training in the geological and planetary sciences and, wherever possible, to integrate these studies with courses in mathematics, physics, chemistry, and biology taken during the student’s earlier years at the Institute. Active involvement in research, particularly during the summer, is encouraged. For geologists, field work is important because it provides first hand experience with geological phenomena that is challenging to completely explain or to fully understand solely from classroom or laboratory treatment. We offer a major in Geological and Planetary Sciences (GPS) that involves a number of core courses and various electives. We also provide information below on more focused tracks in each of the options, such that you can be awarded a major in GPS with a stated track on the transcript. These tracks are offered in geology, geobiology, geochemistry, geophysics, and planetary science. Electives permit students to follow lines of special interest in related scientific and engineering fields. Those who do well in the basic sciences and at the same time have a compelling curiosity about the earth, climate, and the other planets are likely to find these options of interest, especially if they enjoy grappling with complex, interdisciplinary problems. Many students majoring in the earth and planetary sciences pursue further training at the graduate level, while others take jobs that leverage a strong background in earth science including opportunities in sustainability, risk assessment, and climate policy.

For those students with an interest in geobiology, there are options to either be associated with the Biology and Biological Engineering or the GPS division. This association formally affects some of the course requirements that are needed to satisfy the undergraduate degree. Additionally, a students’ affiliation with one division or another is likely to significantly shape their choice of elective courses and potentially research opportunities. We suggest that any interested students discuss this choice with their adviser and/or contact the option representative in the GPS geobiology option.

It is strongly recommended that students start the GPS major with the Ge 11 sequence in the sophomore year. Because Ge 120 ab may not be offered every year, students in the geology track may also need to take Ge 106 and Ge 120 a in winter and spring term of their sophomore year in order to prepare for Ge 120 b the following summer.

Suggestions of elective courses that fulfill degree requirements are listed below, and include some 200-level courses. While these courses are primarily intended for graduate students, advanced undergraduates may enroll with permission of the instructor.

For students simultaneously pursuing a degree in a second option, courses taken as required courses for that option can also be counted as Ge electives where appropriate. However, courses that count toward the electives requirement in the other option cannot simultaneously be counted toward satisfying the elective requirement in GPS.

The following core courses are required for all GPS option tracks:

1. Ge 1 or Ge 11a
2. Ge 11a, 11b, 11c, 11d
3. A writing class, (at least three units)
4. An oral presentation class (at least three units)
5. Ma 2
6. Ma 3 or Ge/Ay 117
7. Ph 2a or Ph 12a
8. One of: Ph 2b, Ph 12b, Ph 2c, Ph 12c

Courses that cover both writing and presentation, e.g. En/Wr 84, that are at least 6 units may be counted towards requirements (3) and (4) above. Students that elect to use Ge 11a for requirement (1) may substitute an elective for Ge 11a in requirement (2). Assuming 3 units each for requirements (3) and (4), the total core requirements totals 87 units; a writing course such as En/Wr 84 (9 units) would increase this to 90 units.

In addition to the core requirements stated above, the student may design a course of study, in consultation with their adviser, that satisfies the following requirements:

63 units of advanced Science, Mathematics, or Engineering outside GPS.

72 units of GPS elective coursework. The combination of the core requirements and the 135 units of GPS major requirements should total no less than 222 units.

In addition to the core requirements stated above, a GPS major with a Geology track must include:

1. Either ACM 95ab or a full-year chemistry sequence, Ch 41abc or Ch 21abc
2. Ge 106
3. Ge 114
4. Ge 115 ab
5. Ge 120 ab
6. Ge 112 or Ge 125
7. Additional elective courses in Ge or ESE to bring the total number of units to 220, including the core classes.

Typical Course Schedules

Similar to En/Wr 84, Bi 24 satisfies both the writing and speaking requirements, (3) and (4), above. Additionally, for the geobiology track, Bi/CNS/NB 195 or Be/Bi 103a can be substituted for the Ma 3 or Ge/Ay 117 courses for requirement (6) above.

We recommend the students consult with their advisers regarding courses that are used to satisfy requirement (3).

The minors in the GPS Division are intended for non-GPS undergraduates to supplement a major degree with knowledge of earth and planetary science. The requirements for the minor are as follows:

1. Ge 11a
2. Select two of the following courses: Ge 11b, Ge 11c, Ge 11d
3. 27 units of 100-level or higher GPS courses, excluding Ge 109

If the courses selected for requirement (3) above are sufficiently focused in one of the GPS options, students may opt to include a track on their transcript (e.g. Minor in GPS with [option] track). Minor tracks are possible in Geobiology, Geochemistry, Geology, Geophysics, and Planetary Sciences. The courses selected for (3) must be approved by the appropriate option representative in the division. Any 27 units that satisfy (3) may be used to satisfy the GPS minor, regardless of focus.
