Environmental Sciences B.S.

Information and Policies

Introduction

The University of California, Santa Cruz environmental sciences (ESCI) major is an interdepartmental, undergraduate-only program. The purpose of the ESCI major is to educate students interested in environmental science problems and issues, with a focus on issues within the physical sciences (as opposed to focusing on biological sciences). The major specializes primarily on the following areas:

Hydrosphere: water resources, water quality, aquatic chemistry, physical oceanography, chemical oceanography, glaciology
Pollution and transport: environmental toxicology, environmental transport/fluid mechanics, environmental monitoring
Global scale environment: climate, climate dynamics, global cycles of water, carbon and nutrients, remote sensing of the environment
Atmosphere: meteorology, air quality, atmospheric chemistry

The core faculty of the major are primarily from two departments, Earth and Planetary Sciences and Ocean Sciences. Faculty from other departments such as Microbiology and Environmental Toxicology and Environmental Studies may also be involved.

In addition to providing comprehensive preparation in the basic physical sciences, and particular breadth and depth in environmental sciences, the curriculum is structured to prepare students for the competitive graduate school and career marketplace. The core of the major includes calculus, physics, chemistry, and core foundational upper-division environmental sciences courses.

Graduates of the ESCI major are expected to continue on to a variety of careers, such as:

Business and industry
Environmental consulting
Governmental agencies at the federal, state, and local level
Non-profit organizations
Research at universities, governmental research institutions, or other scientific agencies
Graduate/professional school in areas such as science, engineering, teaching, law, public health, business

For more information about the affiliated faculty and staff for the major, including areas of interest and facilities, contact e-mails and phone numbers, and how to declare this major, please see our website.

Program Learning Outcomes

The ESCI major has three broad program learning outcomes, each with three specific learning outcomes:

PLO 1: Disciplinary Knowledge Goals

Reservoirs: Understand and describe the properties of the various environmental “reservoirs”, which represent different, interacting physical regimes. For example, a global model might have the atmosphere, oceans, plants and soils as four primary interacting reservoirs.
Processes: Understand and describe the processes governing the properties and evolution of Earth’s physical environment, i.e., the properties and evolution of reservoirs and their interactions.
Application: Apply the knowledge of reservoirs and processes to explain, analyze and predict phenomena within the environmental sciences.

PLO 2: Quantitative Reasoning Goals

Calculation: Utilize mathematical tools (e.g. algebra, calculus) to address questions in the environmental sciences.
Visualization: Interpret and produce visual representations of data in the environmental sciences (e.g. graphs and charts) that conform to disciplinary standards.
Analysis: Use quantitative analysis as the basis for drawing insights and conclusions, while expressing the appropriate assumptions and qualifications.

PLO 3: Written Communication Goals

Mechanics: Write sentences with correct grammar, punctuation, and spelling.
Conventions: Accurately utilize the formatting, stylistic, citation and bibliographic conventions of environmental sciences in the written document.
Organization: Construct paragraphs, sections and an overall document that flows logically and persuasively argues a thesis.

Academic Advising for the Program

Academic advising is available at the Department of Earth and Planetary Sciences (EPS) undergraduate advising office located in the Earth and Marine Sciences Building, and via email at epsadvising@ucsc.edu. The Environmental Sciences undergraduate web pages contain information on all aspects of major advising including: academic planning, upper and lower-division course descriptions, enrichment opportunities in the major like study abroad and undergraduate research, and how to make an appointment with an adviser. Each student should become familiar with the information posted on the website; for further assistance, contact the EPS undergraduate adviser. Transfer students should consult Getting Started in the Major: Transfer Students for more detailed information about academic advising.

Getting Started in the Major: Frosh

This major is not highly sequential or course intensive. Although it is advisable to begin taking courses toward the major in the first year, it is not required. Students begin with general chemistry and mathematics, and an introductory course in physical geology.

Math placement is required for one or more of the foundational courses for this major. For more information, please review the Math Placement website.

Courses completed at a community college or four-year university and/or advanced placement (AP) course equivalencies may be used to fulfill prerequisites.

Every proposed environmental science student will receive emails about advising and first quarter enrollment during the summer. Students with further questions about what to enroll in should email the Environmental Sciences undergraduate adviser.

Within 15 days of receipt of the appeal, the department will notify the student and their affiliated college of the decision. Appeals will be considered on a case-by-case basis and decisions are final. Students may not appeal more than one time.

How to Declare a Major

Students who qualify start the declaration process by creating an academic plan and then scheduling an appointment with the department staff adviser. You must consult with the department’s undergraduate staff adviser to have your academic plan reviewed and approved prior to being able to declare the environmental sciences major. Students should petition to declare the major as soon as they have met qualification requirements and/or reached their declaration deadline quarter, whichever comes first.

Letter Grade Policy

All courses used to satisfy requirements for the environmental sciences major must be taken for a letter grade, with the exception of the following courses, which may be taken pass/no pass: ESCI 195, EART 198 and EART 199 and OCEA 199.

Course Substitution Policy

Relevant courses taken at UC Santa Cruz or other institutions may be substituted for degree requirements by approved petition. Please see the undergraduate adviser for the substitution petition form and more information about this process.

Double Majors and Major/Minor Combinations Policy

Students interested in pursuing multiple majors within the Earth and environmental sciences may NOT declare the following combination of majors:

Environmental Sciences B.S. and Earth Sciences Minor
Any combination of the following: Earth Sciences B.S., Environmental Sciences B.S., Earth Sciences/Anthropology Combined Major B.A.

Should a student choose to double major, they must qualify for and complete the disciplinary communication and comprehensive requirements for each of the majors.

Honors

Honors in the major are determined by a review of grades (typically 3.50 or above) at the time a student applies for graduation. A faculty committee makes the decision based on the quality of all coursework, but especially in the courses required for the major. Extra coursework or independent study as well as more intensive or rigorous coursework and the quality of a capstone project may also be taken into consideration. Highest honors may also be awarded in exceptional cases when a student’s overall grade point average (GPA) is above 3.75 and performance in the senior capstone requirement is equally outstanding. The program reserves the right to withhold honors and highest honors based on other criteria, such as an incident of academic dishonesty.

Honors in the senior thesis are determined independently of major honors, and must be approved by two faculty readers.

No more than one quarter of EART 199 or OCEA 199 may be used as an elective. Lecture/lab combinations count as one course. If a lecture has a lab offered (required or optional), the lab must be passed to count for this requirement.

ENVS 115A and 115L, taken together, are approved as one elective. METX 150 is also allowed as an elective. Up to two courses from other departments may be considered for upper-division elective credit by permission of a faculty advisor. Please consult with an advisor for more details.

Students are encouraged to take more than the minimum number of elective courses and may craft an elective distribution from many areas of specific research and career interests.

Disciplinary Communication (DC) Requirement

Students fulfill the disciplinary communication (DC) requirement through successful completion of either (1) one of the environmental sciences senior capstone seminars (ESCI 191) or (2) a senior thesis based on original research performed by the student (completion of ESCI 195: Senior Thesis is required).

ESCI 191	Capstone Seminar	5
	OR
ESCI 195	Senior Thesis	5

Comprehensive Requirement

All students must satisfy the senior comprehensive requirement. The intent of this requirement is to synthesize knowledge and skills from a student’s undergraduate career. Students should consult an adviser if they have any questions about the timing of their proposed comprehensive requirement activity.

Other capstones will not be considered unless they also satisfy the DC requirement.

Courses that are used to satisfy the capstone may not also count toward fulfilling the upper-division elective requirement.

Satisfactory completion of one of the following capstone course offerings:

Senior Thesis

ESCI 195

Senior Thesis

ESCI 195 requires original research performed by the student. Approval from a faculty sponsor is required prior to embarking on a senior thesis. Completion of the senior thesis is necessary to pass ESCI 195.

ESCI 195 also satisfies the DC requirement.

Capstone Seminar

ESCI 191

Capstone Seminar

Enrollment in ESCI 191 is limited to environmental science majors with senior standing.

ESCI 191 also satisfies the DC requirement.

Planners

The tables below are for informational purposes and do not reflect all university, general education, and credit requirements. See Undergraduate Graduation Requirements for more information.

Students planning a professional career in environmental sciences should take more than the minimum number of courses required for the major, if possible. Four-year students have ample flexibility to take additional electives if they begin with the required courses in their second year. Junior transfers also have flexibility if they have taken most of their lower-division preparatory courses before entry. Further advice can be obtained from the undergraduate adviser and from faculty members.
