BA in Earth Sciences

A major in earth sciences requires the completion of 15 courses approved by the department with a grade of C or better in each of the required earth science and required related courses. In addition, the student must pass an approved summer field course. The earth sciences major is intended to provide the student with a broad earth sciences background in preparation for further, more specialized graduate study or entry-level professional employment.

Required Earth Sciences Courses

  1. CAS ES 101 or 105 or 140 or 142 or 144 or GE 104
  2. ES 302 or 351
  3. ES 360, ES 371; at least three of ES 222, 301, 317, 331, 333, and whichever of 302 or 351 is not taken above
  4. At least two ES courses at the 400 level or above, exclusive of CAS ES 401, 402, 491, 492

Students must also take CAS ES 500 or, with prior approval from the director of undergraduate studies, an equivalent summer field course. In addition, students are encouraged to enroll for one of the following pairs of courses: CAS ES 401, 402; ES 491, 492. Graduation with honors in the major requires successful completion of ES 401 and ES 402. With approval of the Departmental Honors Committee, substantial summer fieldwork may in some instances be combined with either ES 401 or ES 402 as a basis for the honors thesis.

Required Related Courses

Mathematics requirement: CAS MA 123 and MA 124 or CAS MA 127 or CAS MA 129. Chemistry requirement: CAS CH 101, 102, or CAS CH 111, 112. Physics requirement: CAS PY 211, 212 or CAS PY 251, 252.

CAS BI 107 may, in very rare circumstances, be used to satisfy earth sciences major requirements with prior written approval of the director of undergraduate studies.

Cooperative Program with Boston College

This cooperative program permits degree candidates at Boston University to pursue courses in areas of fluid mechanics and geophysics at Boston College. Cross-registration is designated by the symbols XAS (for undergraduate students) and XRG (for graduate students).
