Earth Sciences (ESCI)
Degree Offered: M.S.
This program is offered in Durham.
The Department of Earth Sciences offers the master of science degree in Earth sciences with options in geology, ocean mapping, and a specialization in geochemical systems. The department also offers the master of science degree in hydrology, and a master of science and a Ph.D. in Oceanography. A Ph.D. in Earth and environmental sciences is offered through the Natural Resources and Earth System Science Program. Students may also pursue a graduate certificate in Ocean Mapping, offered in partnership with the Center for Coastal and Ocean Mapping. Graduate students in the department may conduct research with faculty members in the Department of Earth Sciences; the Institute for the Study of Earth, Oceans, and Space; the Center for Coastal and Ocean Mapping; and the School of Marine Science and Ocean Engineering.
The M.S. Geology option is intended for students with interests in petrology, mineralogy, structural geology, tectonics, geophysics, sedimentology, glacial geology, paleoclimate, glaciology, hydrogeology, stratigraphy, paleontology, low- or high-temperature geochemistry, and isotope geochemistry.
The M.S. Ocean Mapping option is intended for students with interests in hydrography and hydrographic survey technology.
The M.S. Geochemical Systems Specialization is intended for students with interests in all aspects of geochemistry: bedrock, sediment, water, ice, and air with particular emphasis on interpreting and modeling the interaction of these media (e.g., biogeochemistry, air quality, and climate change).
The M.S. in Hydrology is intended for students with interests in fluvial processes, global-scale hydrology, groundwater hydrology, hydroclimatology, surface-water hydrology, water quality, and quantitative hydrology.
An applicant to the M.S. program is expected to have completed one year of calculus and at least four semesters of college chemistry, physics, and/or biology; and to have an undergraduate degree or equivalent in geology, chemistry, physics, mathematics, engineering, or the biological sciences. Students lacking some background in a particular area may be admitted provided they are prepared to complete courses, without graduate credit, in which they may be deficient. The program of study a student wishes to follow and the student's undergraduate major determine the level of preparation necessary. The preparation of each student is determined before the beginning of the first semester in residence in order to plan the course of study. Each entering student is assigned an academic adviser to assist in planning a program of study.
Students in the M.S. programs are required to complete the core curriculum for their respective areas and complete either the thesis or non-thesis option.
Students in the thesis option must satisfactorily complete at least 30 credits, which include the credits accumulated in the core curriculum. Students in this option must complete a master's thesis (6 credits) and give an oral presentation of the results.
Students in the non-thesis option must satisfactorily complete at least 34 credits, which includes the core curriculum, a 2-credit directed research project (ESCI #898 Directed Research), and a written and oral presentation of that research.
