Department of Earth, Atmospheric, and Planetary Sciences

The Department of Earth, Atmospheric, and Planetary Sciences offers a bachelor's degree in earth, atmospheric, and planetary sciences, and master's and doctoral degrees in atmospheric sciences, climate science, geology, geochemistry, geobiology, geophysics, and planetary sciences. In conjunction with the Computational Science and Engineering Program (CSE), the department offers a PhD in computational earth, atmospheric and planetary sciences. The department also participates in the MIT-WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering with doctoral degree programs in chemical oceanography, physical oceanography, biological oceanography, and marine geology and geophysics.

Departmental programs apply physics, chemistry, and mathematics to the study of the Earth and planets in order to understand the processes that are active in the Earth's interior, oceans, and atmosphere, as well as the interiors and atmospheres of other planets. The department also uses the basic sciences to understand the past history of the Earth and planets. By combining the past history with models of present physical, biological, and chemical processes, faculty and students work to develop an understanding of the dynamics of systems as diverse as the global climate system, regional tectonics and deformation, petroleum and geothermal reservoirs, and the solar system.

Research in the department is fundamental in nature, but underpins many of the most pressing societal questions of our time: climate and environmental change; natural hazards; natural resources; the origins of life both on Earth and elsewhere. Much of the research is interdisciplinary, so faculty, researchers, and students commonly cross discipline boundaries. Modern problems in these fields are approached by field measurements, laboratory studies, simulations, and theory. Experimental facilities for training and research are available not only in departmental laboratories such as the Earth Resources Laboratory, but also in MIT's interdepartmental laboratories such as the Center for Global Change Science, Kavli Institute for Astrophysics and Space Research, Lincoln Laboratory, Haystack Radio Observatory and Millstone Radar facility, and the Wallace Astrophysical and Geophysical Observatories, and in cooperating institutions such as the Woods Hole Oceanographic Institution.

Graduate Study

The Department of Earth, Atmospheric, and Planetary Sciences offers opportunities for graduate study and research in a wide range of fields:

  • Atmospheric chemistry
  • Atmospheric dynamics
  • Biogeochemistry
  • Climate chemistry
  • Climate dynamics
  • Computational earth, atmospheric, and planetary sciences (in conjunction with the Computational Sciences and Engineering Program)
  • Geology
  • Geobiology
  • Geochemistry
  • Geophysics
  • Paleoclimate
  • Planetary sciences

Study in chemical, physical, and biological oceanography, as well as marine geology and geophysics, is offered in cooperation with the Joint Program with Woods Hole Oceanographic Institution.

Coursework during the first two years is the usual prelude to a thesis demonstrating that the student is capable of independent and creative research. The department offers the following degrees: a Master of Science, a Doctor of Philosophy, or a Doctor of Science in the field of specialization.

A graduate thesis may have either a theoretical, experimental, or observational focus. Modern laboratory facilities, computers, instrumentation, and extensive collections of specimens and data are available to students. Field study is an essential part of the graduate curriculum in geology, geophysics, and geochemistry, and special arrangements may be made for summer employment and field research on departmental projects and with industrial organizations and government agencies. In atmospheric science and climate studies graduate study includes a mixture of theoretical and experimental studies sharing a common appreciation of the dynamics of the underlying processes.

Admission Requirements for Graduate Study

In addition to the general institute requirements for admission listed in the section on Graduate Education, the department requires preparation equivalent to the curriculum for the Bachelor of Science in Earth, Atmospheric, and Planetary Sciences at MIT for graduate studies in that field. For atmospheric sciences, climate studies, meteorology, and oceanography, the most essential element is a sound preparation in mathematics and physics, supplemented if possible by some chemistry. Students taking their undergraduate work at other institutions are advised to include in their programs the equivalent of the mathematics and physics contained in the MIT undergraduate curricula. If students are not fully prepared in certain of the fields or required subjects, they usually are asked to extend their studies in these areas while pursuing advanced work. The doctoral program can be entered without a Master of Science as a prerequisite.

Master of Science in Earth and Planetary Sciences, in Atmospheric Science, or in Climate Science

The General Degree Requirements for the degree of Master of Science in Earth and Planetary Sciences, in Atmospheric Science, or in Climate Science are described under Graduate Education. An individual program of study and research is arranged to suit the special background, needs, and goals of each student. The program is worked out in detail by the student with his or her personal faculty advisor and a departmental committee. There are no foreign language requirements for the degree.

Doctor of Philosophy and Doctor of Science in Earth, Atmospheric, and Planetary Sciences Fields

In consultation with a faculty advisor and a departmental committee, each student in the department's Doctor of Philosophy or Doctor of Science in an Earth, Atmospheric, and Planetary Science Field program develops and follows a specialized program of study and research tailored to their particular background, needs, and goals. A doctoral candidate's program should be broad and may include formal study in other departments in addition to the specialized subjects that prepare the candidate for thesis research. There is no foreign language requirement for the degree. Thesis research normally begins immediately after successful completion of the general examination by the end of the second year. The general examination is intended to test the candidate's aptitude and preparation for independent research.

Thesis research is closely supervised by one or more faculty members interested in and knowledgeable about the research topic, who are chosen by the student and may be members of other departments. The thesis is expected to meet high professional standards, and to be a significant original contribution to the scientific field.

Upon successful completion of the student's designated program and thesis defense, the student is awarded the Doctor of Philosophy or Doctor of Science in the designated field of earth, atmospheric, and planetary sciences.

Interdisciplinary Programs

Computational Science and Engineering Doctoral Program

The Doctoral Program in Computational Science and Engineering (CSE PhD) allows students to specialize in a computation-related field of their choice through focused coursework and a doctoral thesis through a number of participating host departments.
