Faculty / Undergraduate Programs / Graduate Program / Courses

Understanding global environmental issues such as global warming, stratospheric ozone depletion, and worldwide air pollution requires the cooperation of scientists across many fields. Global change is projected to accelerate through the twenty-first century and will impact the ecosystems that preserve the habitability of the planet. The Department of Earth System Science focuses on the atmosphere, land, and oceans, how these interact as a system, and how the Earth will change over a human lifetime. Earth System Science (ESS) is inherently interdisciplinary in scope, linking oceanography, atmospheric and terrestrial sciences, climatology, hydrology, biology, physics, and chemistry to understand the environment. ESS faculty includes chemists, biologists, ecologists, physicists, hydrologists, geologists, meteorologists, engineers, applied mathematicians, and oceanographers. The wide-ranging expertise of ESS faculty and teaching assistants allows students to learn valuable scientific skills in the classroom, laboratory, and field experiences.

Degrees. The Department offers the B.S., M.S.*, and Ph.D. degrees in Earth System Science, and the B.A. degree in Environmental Science.

*The M.S. is awarded only to students admitted to the Ph.D. program.

Undergraduate Programs

BACHELOR OF SCIENCE MAJOR IN EARTH SYSTEM SCIENCE

http://ess.uci.edu/undergrad/bs

 Earth System Science is an interdisciplinary field of study that combines oceanography, atmospheric science, meteorology, geography, geology, hydrology, and environmental science. ESS students gain an understanding of how individual aspects of the environment interact, including the influence of humans on this complex system.

Examples of important questions in Earth System Science include, but are not limited to, the influence of atmospheric chemistry on climate and air quality, biological controls on the chemistry of the oceans, and physical controls on atmosphere and ocean circulation.

The Earth System Science (B.S.) program provides students with a fundamental understanding of the oceanographic, atmospheric, and terrestrial sciences. This program of study prepares students for careers in science, research, or technical fields. Students learn to apply basic sciences (physics, chemistry, mathematics, and biology) to understand the major processes and systems governing the Earth's climate, biogeochemical cycles, and global change. Central to the B.S. program is an understanding of relevant scientific literature, methods to collect/analyze data, and interpret results in the context of scientific theory. Students will learn to work collaboratively to understand and address complex problems and communicate scientific knowledge.

Through the core course work, students will learn to explain the current and projected future state of the Earth system in the context of past climate change and current human activities. Once the core course work is complete, students are encouraged to focus on a particular area within Earth System Science and to choose electives that build a coherent core of knowledge. Focus areas include but are not limited to climatology, biogeochemical cycles, oceanography, hydrology, terrestrial sciences, and atmospheric sciences.

Earth System Science students are encouraged to become directly involved in research. The Department provides excellent opportunities to learn from and work with recognized experts in the field, while fulfilling degree requirements. ESS 198 may satisfy Department and UCI upper-division writing requirements.

Careers for the Earth System Science Major

Some students go on to graduate school in physical sciences, engineering, or related areas. Others begin careers as research scientists in academic, public, or private institutions (may require a graduate-level degree). Options that may be available are scientist positions in the following roles: environmental policy and planning, environmental consulting, air quality monitoring and assessment, laboratory analysis, scientific research, science education, natural resource management, wildlife management, conservation and environmental protection, and water resource management.

HONORS PROGRAM IN EARTH SYSTEM SCIENCE

The Department of Earth System Science awards honors to students who have completed a customized year-long research program in their senior year. ESS honors students engage in advanced research, alongside faculty, research staff, and graduate students within well-equipped laboratories in Earth System Science. The program involves both conducting original research and communicating scientific findings.

The Honors Program in Earth System Science provides an opportunity for selected students majoring in Earth System Science or Environmental Science to pursue research with faculty in the Department during their senior year. Admission to the program is based on an application normally submitted by the sixth week of the spring quarter during the junior year.

To be considered for Departmental Honors, a student must have satisfied the following requirements:

1.   Completion of all mathematics, chemistry, and physics requirements for the major;

2.   Completion of Earth System Science 51, 53, 55 or Earth System Science 60A-B-C;

3.   Achievement of an overall GPA at UCI of at least 3.3; and

4.   Achievement of a GPA in Earth System Science courses of 3.4.

Students must also demonstrate potential for carrying out research of honors quality, as judged by the Earth System Science faculty member who will supervise their research. Application materials are available at http://ess.uci.edu/undergrad/honors.

Once admitted to the program, students will enroll in Honors Research in Earth System Science (H199A-B-C) and Honors Thesis in Earth System Science (H198).

In the Honors Research series, students will commit 10-15 hours a week to conduct research with an ESS faculty. At the end of each quarter, a written report is required.

In the Honors Thesis course, students will prepare and submit a seminar, poster, and written thesis describing their research. The thesis will be written in the style of a scientific manuscript, with separate abstract, introduction, methods, results and discussion sections. If the thesis is deemed honors quality by the ESS faculty and the student's final accumulative GPA is above 3.3, the student will graduate with Departmental Honors.

MINOR IN EARTH AND ATMOSPHERIC SCIENCES

The science of the Earth as a system has implications for many fields of study. Students interested in understanding how the Earth's systems work can complete the requirements for a minor in Earth and Atmospheric Sciences. The program is primarily designed for students in the natural sciences and engineering who wish to explore interdisciplinary problems and broaden their studies to include the application of their fields to understanding the Earth system.

NOTE: This minor is not available to students in the Earth System Science (B.S.) or Environmental Science (B.A.) majors.

Requirements for the Minor

Earth System Science 51, 53, 55, or Earth System Science 60A, 60B, 60C, plus four electives chosen from the approved elective list for the B.S. in Earth System Science major, at least two of which must be Earth System Science courses.

Graduate Program

The Earth, as a coupled system of atmosphere, ocean, land, and cryosphere, has changed in our lifetime. The observed depletion of stratospheric ozone at high latitudes has been attributed directly to industrial use of halocarbons. Global warming is likely to result from increases in the atmospheric concentrations of greenhouse gases, such as carbon dioxide and methane, which are released by the use of fossil fuel and agricultural practices. These examples illustrate the ability of humans to alter the global environment on the time-scale of decades. Understanding the sensitivity of the Earth's climate system requires a broad base of scientific knowledge, which includes detection, quantification, and prediction of the rates of change of chemical, physical, and biological variables.

The Department's doctoral program is aimed at training new research scientists in the field of Earth System Science. The graduate education provides a comprehensive curriculum, along with opportunities to conduct groundbreaking research. The Department's doctoral-level students are expected to become researchers with a global perspective and broad research skills as well as a high level of expertise in specific areas. Active programs of research are underway in atmospheric chemistry, biogeochemical cycles, and physical climate.

NOTE: Students are admitted to the Ph.D. program only; the master's degree is awarded upon progress to the Ph.D.

Course Requirements. Students must complete a minimum of 10 approved graduate-level courses, including the core curriculum (Earth System Science 202, 212, 224, 226, 228, 240, 266, and 298), with an average grade of B or better. All courses must be approved by the student's advisor.

Residency. Academic Senate regulations specify a minimum period of residence of six quarters for Ph.D. candidates. Enrollment in a minimum of 12 units of graduate/upper-division course work per quarter is required. Registration in every regular academic session is necessary until all requirements for the degree have been completed, unless a formal Leave of Absence is granted by the Graduate Division. All Ph.D. requirements must be completed within 15 quarters in residence (five years), excluding summer quarters. Exceptions must be put to a vote of the Earth System Science faculty. The maximum time permitted is seven years.

Comprehensive Examination. Progress toward the degree and readiness to begin research is assessed by a comprehensive examination covering breadth, general knowledge, and the ability to integrate and use information covered in the core curriculum and other course work. At the end of the spring quarter, the ESS Comprehensive Examination Committee administers the written and oral examinations. The oral comprehensive examination is offered after the written examination and provides an opportunity to clarify questions that arise from the student's performance on the written examination.

Teaching and Seminar. Students are required to complete a teaching assistant training program and to have a minimum of two quarters of experience as a teaching assistant, provided opportunities are available. Students can enroll in Earth System Science 399 while serving as a teaching assistant. Students are also expected to participate in the Earth System Science seminar.

Advance to Ph.D. Candidacy. Following completion of the Comprehensive Examination, those students who receive a recommendation to continue Ph.D. work will pursue research on a potential dissertation topic and then take the Advancement to Candidacy Examination. This oral examination is given by a faculty committee, including extra-departmental faculty. The normative time for advancement for candidacy is two years.

Dissertation. After advancing to candidacy, students are expected to be fully involved in research toward writing their Ph.D. dissertation. Students should keep in steady contact/interaction with their Doctoral Committee. A dissertation based on original research and demonstrating critical judgment, intellectual synthesis, creativity, and clarity in written communication is required for the Ph.D. degree. The dissertation must summarize the results of original research performed by the student under the supervision of a faculty member of the Department. The dissertation will be evaluated by the Dissertation Committee, based on suitability for publication in a peer-reviewed journal of high editorial standards. The dissertation may be a compilation of published papers or manuscripts accepted for publication, so long as the candidate has produced a major proportion of the material independently. The Dissertation Committee approves the format and content, which must meet University requirements for style, format, and appearance.
