GEOPHYS 90: Earthquakes and Volcanoes (EARTHSYS 113)

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

GEOPHYS 104: The Water Course (EARTHSYS 104, EARTHSYS 204, GEOPHYS 204)

The Central Valley of California provides a third of the produce grown in the U.S., but recent droughts and increasing demand have raised concerns about both food and water security. The pathway that water takes from rainfall to the irrigation of fields or household taps ('the water course') determines the quantity and quality of the available water. Working with various data sources (measurements made on the ground, in wells, and from satellites) allows us to model the water budget in the valley and explore the recent impacts on freshwater supplies.

GEOPHYS 148: Machine Learning and the Physical Sciences (CME 215, GEOPHYS 248)

This course provides a survey of the rapidly growing field of machine learning in the physical sciences.

Students have the opportunity to apply this emerging methodology to their own research interests across all fields of the physical sciences, including geophysics, climate, fluids, or other systems where the same technique applies. Students develop individual projects throughout the semester. Recommended Prerequisite: Calculus (e.g. Math 21), Differential Equations (e.g. MATH 53 or PHYSICS 111) or equivalents.

GEOPHYS 190: Near-Surface Geophysics: Imaging Groundwater Systems

Introduction to geophysical methods that can be used for imaging and characterizing groundwater systems. Recurring periods of drought and flooding in California have led state and local water agencies to search for ways to capture flood water and use it to recharge (refill) the over-pumped groundwater systems. The course this year will be structured around analyzing a new geophysical data set to identify optimal locations for recharge. The data set: 26,000 kilometers of electromagnetic data, acquired with a helicopter-deployed system, which image the groundwater systems of the Valley to a depth of ~300 m. We will analyze these data to find optimal sites for recharge by mapping out the variation in sediment type and identifying pathways for flow. Pre-requisite: CME 100 or Math 51, or co-registration in either.

GEOPHYS 228: Modeling Earth (GEOPHYS 128)

Most problems in Earth Science are dazzling and beautifully complex. Abstracting from this natural complexity to identify the essential components and mechanisms of a natural system is perhaps the most important, but commonly overlooked, task for developing testable mathematical models for Earth and Environmental Science. This course focuses on conceptual model development, rather than addressing the variety of formal mathematical techniques available for the analytical analysis or numerical simulation of a model. Recommended Prerequisites: CME 100 or MATH 51 (or equivalent)
Terms: Win, Spr | Units: 3-4

GEOPHYS 236: An Introduction to Quantitative X-ray Microanalysis (EPS 216, MATSCI 236)

This course will introduce students to the theories and techniques involved in measuring and quantifying the chemical composition of solid materials using X-ray spectroscopy. The course will be largely focused on electron beam instruments including scanning and transmission electron microscopes (SEM-EDS and TEM-EDS) and Electron Probe Microanalyzer (EPMA-EDS; EPMA-WDS), with the laboratory component consisting of a combination of instrument training and data collection on multiple electron beam instruments, coupled with in-lab exercises covering the methods associated with the evaluation, processing, and presentation of X-ray data. Students will also learn to utilize multiple cutting-edge data quantitative spectroscopy software packages. The goal of this course is to provide graduate students with the tools required to make informed decisions when designing projects that involve understanding the composition(s) of solid materials at the nano- and micro-scales. Introduce students to the theory and technique behind determining the chemical composition of solid materials using X-ray spectroscopy. (CROSS-LISTED WITH EPS 216 and GEOPHYS 236)

GEOPHYS 237: Evolution of Terrestrial Planets (EPS 238)

Despite forming in the inner solar system from broadly similar starting materials, Mercury, Venus, Earth, Mars, and the Moon each represent a unique outcome of the planetary formation process. Processes occurring deep inside planets drive the evolution of planetary crusts and atmospheres, which both control planetary habitability. This course explores how geophysical approaches such as gravity, topography, seismology, heat flow, and magnetism provide insight into the thermal and chemical histories of each rocky world. We cover how planetary scientists study ancient processes such as core formation, impact cratering, magnetic field generation, mantle convection, and tectonics by a combination of spacecraft measurements, modeling, and laboratory analyses of extraterrestrial materials. Recommended prerequisites: PHYSICS 41, 43, and MATH 51 or CME 100, or instructor consent.
