The Department of Earth System Science offers a PhD program in a wide range of fields, including water resources; ocean circulation; land use change; sustainable food and water practices; climate, tectonics, and landscape evolution; ocean biogeochemistry; climate and earth system dynamics; soil and environmental biogeochemistry; molecular microbial ecology; and, geostatistics. The size and the breadth of interest of the department's faculty provide numerous opportunities for field-based research as well as laboratory and numerical experiments. We apply the most modern applications of instrumental analysis and spectroscopy to problems in the Earth sciences.
Applications to Earth System Science graduate programs must be received by the deadline of Tuesday, December 6, 2022 5:00 pm Pacific Time in order to be considered for 2022-23 admission cycle. Applications will open in mid-September.
Applicants to the Knight-Hennessy Scholars program must apply to that program by Wednesday, October 12, 2022 at 1:00 pm Pacific Time, and apply separately to the Department of Earth System Science by December 6, 2022.
Before you Apply
Students are admitted to our graduate program specifically to work with an individual faculty member (or two, if co-advised). There is no rotation program in the first year. Therefore, it is important that you familiarize yourself with the research conducted by the departmental faculty (visit Faculty profiles and Earth System Science research groups), and contact individual faculty members to inquire about their research and discuss your background and goals.
Electronic Stanford Graduate Application
Read through the instructions and begin your electronic application on the Stanford Graduate Admissions website. When prompted to select the program to which you are applying, select "Earth System Science PhD" or "Earth System Science MS". Before you apply to our MS degree, be sure to check with your potential faculty advisor to determine whether they accept terminal MS students, since many do not. Please check the admissions FAQ page for more information
Statement of Purpose
Your Statement of Purpose should describe your reasons for applying to our graduate program. Importantly, you should identify one or more potential faculty research advisors and discuss what aspects of their research are of interest to you and/or any research question (broad or specific) that you would like to pursue with them. Include details about your preparation for this field of study, future career plans and goals, and any other aspects of your background and interests that may aid the admissions committee in evaluating your aptitude and motivation for graduate study.
Your statement should be uploaded as a Word or PDF file in the electronic application (it should not exceed 2 single spaced pages ).
The Supplemental Information is part of the online application. You will be asked to identify up to four faculty members with whom you want to work and why. You can simply write N/A if you have less than four names in mind.
GRE and TOEFL Scores
GRE - The general GRE test is optional. After communicating with your potential advisor, if you think that submitting GRE scores will help your case for admission, then feel free to do so. If submitted, scores must be from tests taken within the past five years, and must be reported directly to Stanford from ETS. The Stanford score recipient number is 4704. To facilitate preliminary review of your application, please provide your scores in the electronic form if you plan to submit them. If you have previously applied to Stanford (within the past five years), we have your prior test scores. We do not have a minimum GRE score requirement, and we do not track average scores for admitted applicants.
TOEFL - Applicants whose first language is not English must submit TOEFL scores from a test taken within the last eighteen months. The TOEFL is waived for individuals who have earned a U.S. bachelor's or master's degree from a college or university accredited by a regional accrediting association in the United States or the equivalent of either degree from a non-U.S. college or university of recognized standing where all instructions are provided in English. This exception does not apply if the courses were completed in a country where English is spoken but not all instruction is provided in English. Scores must be reported directly to Stanford from ETS. Your minimum score must be 100 (internet based) OR 600 (paper based). Please see the Graduate Admissions Office website for additional information about required exams. Stanford does not accept IELTS scores.
* Students are strongly advised to take standardized tests (if applicable) no later than mid-October to ensure that scores are transmitted to the department by the application deadline.
Letters of Recommendation
Following the instructions in the electronic application system, arrange for your three letters of recommendation to be submitted electronically. It is required by the University that at least one of the recommenders be a faculty member at the last school you attended as a full-time student unless you have been out of school for more than five years. Letters of recommendation that can speak first-hand about your research training and course preparation will be most helpful. Substitutions for faculty recommendations may include work associates or others who can comment on your potential for graduate work. All letters of recommendation must be received by the application deadline. Applicants are responsible for notifying references of the deadline.
On the ApplyWeb application, list any degree program in which you are currently enrolled, as well as every institution you have attended as a full-time student for one or more academic years. Upload transcripts from every institution you attended as a full-time student for one or more academic years, as well as transcripts from degree programs in which you are currently enrolled.
When submitting official transcripts, use certified electronic transcripts to submit your documents. See details below.
Stanford does not consider transcripts that come from the ApplyWeb application or that have been in the applicant's possession as official. Transcripts submitted by the student as email attachments are also not considered official. Final official transcripts must contain the following information:
- Completion of coursework required for the degree
- Degree earned and date the degree was conferred
- Official stamp, seal, and/or embossed marking from the school
- Transcripts and degree documents that are in a language other than English must be accompanied with an official English translation
- Certified Electronic Transcripts: Secure electronically delivered transcripts that are passcode protected, digitally signed, and properly certified by the issuing institution are required and are sent to us only from the issuing institution or its authorized agent. Send to: firstname.lastname@example.org Transcripts sent as email attachments or by the student will be rejected.
- ApplyWeb CertiFile Service: International and domestic final official transcripts/degree certifications delivery method is via the ApplyWeb CertiFile Service. To submit the order go to your ApplyWeb Applicant Activity Page by clicking on the Review Your Activity link at https://www.applyweb.com/stanford . There is a fee for this service.
- If your institution will be mailing a traditional paper transcript, it must be in an official sealed envelope that is signed and stamped across the envelope flap by the appropriate academic officer at the institution issuing the document. If the envelope has been opened or there is no stamp or signature across the envelope flap, it will not be accepted. Have the institution send it to the address below.
