Geophysics (GP)

Geophysics PhD and Masters’ degree programs at Scripps Institution of Oceanography

Students in the Geophysics (GP) graduate program study Earth and other planets to advance our fundamental understanding their origin, composition, and evolution, and explore the implications for life, for the environment, and for society.

The graduate program provides a broad education in the fundamentals of geophysics, alongside research and coursework spanning multiple specializations. Our flexible curriculum and multidisciplinary researchers enable us to welcome graduate students from a diverse range of backgrounds in science and engineering, producing graduates who are well prepared for future careers in academia, industry, or public service.

Our multidisciplinary program offers graduate students a unique hands-on, collaborative learning environment. A core academic curriculum provides the foundation for working on research projects that emphasize observational techniques and the collection of novel datasets linked to testing new theoretical and computational approaches. GP students participate extensively in field experiments, instrument development, laboratory investigations, and shipboard expeditions. Many students take advantage of the opportunity to serve as a teaching assistant at some point during the course of their degrees.

 

Is our Geophysics graduate program for you?

At Scripps you can enroll for either a PhD or Masters (MS) degree. Many PhD students receive an MS on the way to the PhD by completing sufficient units of coursework.  Join us for our annual Pre-Application Virtual Open House on November 17th at 9-10 a.m. (PST) to decide which might be best for you, and why you should choose Scripps. Register for the Virtual Open House here.

Adrian Borsa aborsa@ucsd.edu
Geodesy and the water cycle. Projects use observations of Earth surface deformation and gravity to understand the movement and storage of freshwater in the Earth system. Current studies target mountain watersheds in the Western USA, groundwater in California’s Central Valley, and Arctic permafrost.

Catherine Constable cconstable@ucsd.edu
Geomagnetism. Possible projects include modeling paleosecular variation and linking paleomagnetic records of geomagnetic excursions and reversals to numerical dynamo simulations. Website: igppweb.ucsd.edu/~cathy 

Steven Constable sconstable@ucsd.edu
Marine electromagnetic methods.  Projects include the study of offshore groundwater, marine gas hydrate, tectonic plate boundaries, and pretty well any other geological feature found offshore.  We collect and interpret our own field data, but the lab is also interested in developing algorithms and software needed for data processing and modeling/inversion of EM data.
Website: marineemlab.ucsd.edu

Yuri Fialko yfialko@ucsd.edu
Geodesy and tectonics. Current projects include studies of sub-surface geometry of the Southern San Andreas Fault using space geodetic and seismic data, probing rheologic structure of the Earth using postseismic transients, evaluation of state of stress in seismogenic crust.

Helen Fricker hafricker@ucsd.edu
Glaciology and remote sensing.  Satellite remote sensing (particularly radar and laser altimetry) of the Antarctic and Greenland ice sheets; mostly focusing on the ice shelves, to understand mass loss processes driving changes (basal and surface melting, and iceberg calving).
Website: polar.ucsd.edu

Alice Gabriel algabriel@ucsd.edu 
Computational and theoretical seismology. Projects are available which use high-performance computing and physics-based modeling constrained by a multitude of observations. Application areas range from the seismic cycle in subduction zones and tsunami genesis, to strong ground motion scenarios in complicated settings, to induced seismicity. Projects may involve utilising new methods in terms of numerical discretisation, uncertainty quantification, imaging and monitoring.

Jennifer Haase jhaase@ucsd.edu
The Haase research lab investigates and develops innovative uses of GPS and GNSS technology for sensing the environment and improving understanding and prediction of geophysical processes, including earthquake hazard. New students are welcome to imagine creative investigations of the tropical atmosphere including applications to hurricanes, storm surge, the North American monsoon, convection and convectively generated equatorial waves.
Website: jhaase.scrippsprofiles.ucsd.edu

Gabi Laske glaske@ucsd.edu
Observational seismology. Research projects typically cover aspects of structural seismology. Primary targets are the measurement and tomographic modeling of surface wave dispersion in combination with other seismic observables. Our research projects often involve the collection and analysis of ocean bottom seismic data in the Pacific ocean. 
Website: igppweb.ucsd.edu/~gabi

Matti Morzfeld matti@ucsd.edu
Data assimilation and theoretical geophysics. The research projects are interdisciplinary and revolve around creating new numerical methods (Markov chain Monte Carlo or optimization) and their application across disciplines in geophysics.
Website: igppweb.ucsd.edu/~mmorzfeld

Ross Parnell-Turner rparnellturner@ucsd.edu
Marine geophysics. Possible projects, with sea-going opportunities, will investigate oceanic crustal formation, faulting and magmatism using earthquake seismology and underwater mapping with robots.

Additional Information


Program of Study for PhD

Turner cruise

Students are admitted to the GP curricular group within the Geosciences of the Earth, Oceans, and Planets (GEO) Program based on their interests and the affiliations of their adviser. Each student is assigned a first year advisory committee, comprising their primary advisor and the three person GP departmental committee. Although students may change curricular groups in the course of the year, they must choose which departmental exam they will take. Departmental exams have similar structures among the curricular groups within GEO (a written exam at the end of spring quarter of their first year and an oral exam before the beginning of fall quarter of their second year). The material covered is quite different so students should begin preparing for a particular group's exam from the start. Students are encouraged to begin a research project from the beginning and typically do not hold teaching assistant positions during their first year. Students may change advisers during their first year, but it is important for them to find an adviser by the end of the first year so that they are ready to work on research over the summer and develop a thesis proposal during their second and third years. Students are normally expected to present this proposal at their qualifying exam by the end of their third year.

No single course of study is appropriate to every student in the geophysics curricular group: instead, there is a sequence of foundational classes that each student is expected to complete successfully during the first year, together with a three-quarter seminar sequence on Geophysics Research Skills. Additional graduate class electives or research units (SIO299) under the guidance of a specific instructor provide a minimum of 12 units/quarter required for full-time study. Electivesshould be chosen from the broad range of available topics in consultation with the first-year guidance committee and the student’s advisor to provide breadth of expertise and to support the individual interests of the student. Some students will find it useful to take courses offered by other curricular groups across Scripps or by other departments on UCSD’s General campus.

The content of the foundational courses combined with the research skills acquired during the first year seminar forms the basis for the written departmental examination. A list of graduate classes offered by the GP faculty is provided below.

Students are also encouraged to attend Geophysics and Earth Section seminars for exposure to a broad range of geophysical research topics.


Program of Study for MS

The geophysics master’s degree provides a solid grounding in the fundamentals of geophysics for students intending to pursue professional positions in government, industry, or nonprofit organizations or to apply to PhD programs. Two different degree options are available:


MS Plan I—Thesis

This plan combines course work and research, culminating in the preparation of a thesis. A minimum of thirty-six units of credit is required: twenty-two units are expected from Foundational Courses (see below); and twelve units of research work (SIO299) lead to the thesis. Students should contact a thesis adviser and co-adviser prior to, or as part of, the application process. Students are rarely accepted into the program without this prior consultation. This two-member faculty committee, in consultation with the student and the Geophysics Curriculum Advisor, will select the courses and research topic to be completed in two years or less.


MS Plan II—Comprehensive Exam

This course of study is intended to be completed in a single year and requires a minimum of thirty-six credit units. Twenty-two units are expected from the Foundational Group and the remaining twelve units will be selected in consultation with the student’s faculty mentor and geophysics departmental committee. Students must pass a written comprehensive examination at the end of the spring quarter of the first year, which will cover material in the foundational course work.
