Results for GEOPHYS

The physics and chemistry of volcanic processes and modern methods of volcano monitoring. Volcanoes as manifestations of the Earth's internal energy and hazards to society. How earth scientists better forecast eruptive activity by monitoring seismic activity, bulging of the ground surface, and the discharge of volcanic gases, and by studying deposits from past eruptions. Focus is on the interface between scientists and policy makers and the challenges of decision making with incomplete information. Field trip to Mt. St. Helens, site of the 1980 eruption.

Is the "Big One" overdue in California? What kind of damage would that cause? What can we do to reduce the impact of such hazards in urban environments? Does "fracking" cause earthquakes and are we at risk? Is the United States vulnerable to a giant tsunami? The geologic record contains evidence of volcanic super eruptions throughout Earth's history. What causes these gigantic explosive eruptions, and can they be predicted in the future? This course will address these and related issues. For non-majors and potential Earth scientists. No prerequisites. More information at: https://stanford.box.com/s/zr8ar28efmuo5wtlj6gj2jbxle76r4lu

Sustainable Urban Systems (SUS) Project is a project-based learning experience being piloted for an upcoming new SUS M.S. Program within CEE. Students are placed in small interdisciplinary teams (engineers and non-engineers, undergraduate and graduate level) to work on complex design, engineering, and policy problems presented by external partners in a real urban setting. Multiple projects are offered throughout the academic year and may span multiple quarters. Students are expected to interact with professionals and community stakeholders, conduct independent team work outside of class sessions, and submit deliverables over a series of milestones. To view project descriptions and apply, visit http://sus.stanford.edu/courses/.

The purpose of this course is to provide an introduction to the physics, systems, processing, and analysis of ice penetrating radar, preparing students to use it as a quantitative research tool. Target students are graduates or advanced undergraduates in geophysics, glaciology, planetary science, or engineering with an interest in the use of radar to study glaciers, ice sheets, or icy planets.nPrerequisite: EE 142 or EE 242 or PHYS 43 or instructor consent.

The structural and stratigraphic interpretation of seismic reflection data, emphasizing hydrocarbon traps in two and three dimensions on industry data, including workstation-based interpretation. Lectures only, 1 unit. Prerequisite: 222, or consent of instructor. (Geophys 183 must be taken for a minimum of 3 units to be eligible for Ways credit).

Field-, lab-, or computer-based. Faculty supervision. Written reports.

For seniors writing a thesis based on Geophysics research in 196 or as a summer research fellow. Seniors defend the results of their research at a public oral presentation.

Experimental, observational, or theoretical honors project and thesis in geophysics under supervision of a faculty member. Students who elect to do an honors thesis should begin planning it no later than Winter Quarter of the junior year. Prerequisites: department approval. Seniors defend the results of their research at a public oral presentation.

How fast can ice sheets disintegrate? Why do volcanoes erupt? Which processes govern thenoccurrence of landslides? And can we reduce the destructive reach of tsunamis and storm surges?nThe common denominator of what at first glance might seem like disparate systems isnmultiphase flow. The dynamic interactions between multiple solid and fluid phases, such as icenand melt-water; lava and gas; vegetation and waves, give rise to drastic nonlinearities that governnabrupt change. This class explores the role of multiphase instabilities in the onset and evolutionnof extreme events. We will explore the different types of instabilities that arise in differentnmultiphase aggregates and why they might be critical for understanding the nonlinear behaviornof natural systems.

The principles of imaging complex structures in the Earth subsurface using 3-D reflection seismology. Emphasis is on processing methodologies and algorithms, with examples of applications to field data. Topics: acquisition geometrics of land and marine 3-D seismic surveys, time vs. depth imaging, migration by Kirchhoff methods and by wave-equation methods, migration velocity analysis, velocity model building, imaging irregularly sampled and aliased data. Computational labs involve some programming. Lab for 3 units. Offered every year, Spring quarter.
