Graduate Program

Most of the Earth–from surface to core– is made up of crystalline material (minerals), but with important minor components of water-rich fluids and magmas which are responsible for the destruction and creation of new minerals. Together these ‘earth materials’ – and the processes responsible for them coming into being – have shaped Earth for over 4.5 billion years. We will explore the properties of earth materials including their atomic structure, their physical and chemical stability, and the basic principles that govern the chemical composition, occurrence, structure, and classification of minerals. A portion of the course will be devoted to the study of other terrestrial bodies (e.g., Mars and the Moon) and meteorites that make up the primordial building material for planets that we see today.

Most introductory courses to chemical oceanography cover a variety of topics that are only related because they are under the broad umbrella of chemical oceanography. Some of these topics include the carbon dioxide and inorganic carbon chemistry, salinity, marine nutrients, dissolved gases and organic constituents. Similarly, most discussions of climate change and chemical oceanography only touch on ocean acidification. This course seeks to provide the same broad prospective to conventional chemical oceanography courses but will interweave the unifying theme of climate change into these numerous and diverse topics.

PREREQUISITES: CHEM 131, MATH 161

A course on modern methods for estimating models, and their uncertainty, from observational data in the Earth sciences. The course emphasizes concepts in parameter estimation, time series analysis, and statistics, using matrix inverse methods. Examples are taken exclusively from environmental science datasets: sea-surface temperature, precipitation and river flow, ground vibration, the chemical composition of sea-floor samples, etc. Problem sets and weekly computer exercises provide theoretical foundations and adequate practice needed for proficiency in data analysis.

PREREQUISITES: First two courses in the MATH 140 or MATH 160 calculus sequence

This course introduces the theoretical foundations of seismology: the study of (an-)elastic vibrations, the sources that generate them and the planetary interiors through which they propagate. It plays a leading role in addressing key scientific questions involving our planet's dynamic systems and other terrestrial planetary interiors, providing direct constraints on planetary structure and its composition from crust to core. We will cover fundamental concepts of elasticity, stress, strain, seismometer design, the derivation of the seismic wave equation and its application to describing the full seismic spectrum. In addition to learning theoretical fundamentals, we will explore frontier applications in computational and planetary seismology e.g., (i) earthquake detection and location on the Earth, Moon and Mars, (ii) Auto-adaptive imaging in 1D, 2D & 3D, and (iii) extracting deterministic waves from

The atmosphere helps to maintain habitable temperatures on our planet's surface, shields life from destructive cosmic and ultraviolet radiation and contains gases such as oxygen and carbon dioxide, which are essential for life. In this course we will work toward an understanding of several important questions. What is in the Earth's atmosphere? What are the sources and sinks of the most important gases in the atmosphere? How does the atmosphere affect the Earth's surface climate? What is the role of photochemistry in atmospheric composition? How does the atmosphere interact with the land and oceans? How has human activity affected the atmosphere? Registration for recitation is required at the time of course registration.

This course investigates Geobiology, the study of the interactions between the biosphere (living organisms and their products) and the geosphere (atmosphere, hydrosphere, lithosphere, cryosphere). In the first part of the semester, the class will explore how the geopshere's chemical and physical processes influenced life and evolution and how life influenced the Earth system during roughly the last 4 billion years. This will be done mainly through the reading and discussion of seminal papers. The second part of the semester will focus on students' investigation of specific geobiology topics, like microbial weathering of minerals, biomineralization, the role of different microbial metabolisms in elemental cycling, the ocean redox history and its relationship to the origin of life itself. In addition to learning geobiology fundamentals, students will learn how to undertake a scientific literature search, read and understand scientific material, brainstorm and develop new ideas and write a final research paper.

Time is at the heart of the Earth and Planetary Sciences. Without quantitative knowledge of absolute or relative time, no discipline with a historical perspective could function. The goal of this course is to provide students with an overview of the fundamental geochemical tools that are used for establishing quantitative timescales of Earth and Planetary processes. By integrating concepts of radiogenic isotope geochemistry, diffusion kinetics and analytical geochemistry, this course will explore the principles and applications of geochronology, thermochronology and geospeedometry. Students are expected to have a general knowledge of mineralogy, petrology and basic thermodynamics prior to taking this course. Instructor permission required for undergraduates.

Over the last few decades, numerical biogeochemical models have provided new insights into the marine carbon cycle, its contribution to past climate change, and its potential responses to future climate warming. In this practical class, students will build simple biogeochemical models-ranging from "box" models of marine microbial ecosystems to three-dimensional nutrient cycling models-and design experiments to address climate change hypotheses. They will also be taught to analyze output from state-of-the-art climate models used by the Intergovernmental Panel on Climate Change. Students will not only learn invaluable programming skills, but also gain a deeper intuition of the ocean carbon cycling and its role in the global climate system.

PREREQUISITES: MATH 165 or equivalent, EESC 212

Global atmospheric models are critical research and policy tools used to understand and predict the weather, climate change, and air pollution. This course provides an applied introduction to the physics, chemistry, and numerical methods underlying simulations of the spatial and temporal evolution of mass, energy, and momentum in planetary atmospheres. Topics include: finite-differencing the equations of atmospheric dynamics, radiative transfer models, numerical methods for solving systems of chemical ordinary differential equations, parameterization of small-scale processes, surface exchanges, inverse modeling, and model evaluation techniques. Assignments focus on the implementation and application of simple models by students. Students will also gain experience using state-of-the-science models of atmospheric chemistry and/or climate in a final project of their choosing.

The physical circulation of the ocean controls the uptake and redistribution of heat and carbon dioxide from the atmosphere, so is a critical regulator of global climate. This course will provide a comprehensive and quantitative treatment of the physics that underlie ocean circulation. The dynamical equations that govern circulation will be introduced early in the course, then applied and simplified to understand the force balances that explain the major circulation regimes of the ocean: surface wind-driven circulation, gyres and western boundary currents, and the deep thermohaline circulation. The course will then explore how these circulation regimes also shape the biology of the ocean, and interact with atmospheric circulation and the global climate system. The course will involve solving and manipulating differential equations, and a background understanding of these methods is required. However, no previous oceanography experience will be assumed.

PREREQUISITES: PHYS 121, MATH 165

Most courses in stable isotopes highlight the analytical techniques and classic examples of applications of stable isotopes. However, the stable isotope investigations in this course will stress the fundamentals of stable isotope models, along with their underlying assumptions, guided by several classic applications. Not only will we learn the equations used in these pioneering applications, but we will set-up and derive these equations. The goal of this course is to equip students with the knowledge needed to both dissect as well as manipulate traditional stable isotope models so that they can analyze their data in the most appropriate and intelligent fashion.

PREREQUISITES: CHEM 131-132 and MATH 161-162

The goal of this course is to provide an overview of the equilibrium and kinetic processes that govern the elemental and isotopic composition of rocks and minerals. The course will be divided into two broadly equal components. In the first part, the fundamentals of thermodynamics, phase diagrams, and selected examples in earth systems will be explored. The second half of the course is devoted to understanding the non-equilibrium case for earth materials; diffusion in minerals and melts is emphasized. Students are expected to have a general knowledge of mineralogy, petrology, and very basic thermodynamics prior to taking this course.

The Earth's climate is changing in a potentially fundamental way because of human activity. In this course we will look into Earth's climate history in order to gain a better understanding of how the climate system works and what we can expect from Earth's climate in the future. During its history, the Earth has gone through periods that were much warmer as well as periods that were much colder than today. By examining the geological record of the environmental conditions, we can gain insights into how key parameters such as greenhouse gas concentrations, insolation and positions of the continents influence the climate system. The students will also learn how different paleoclimate indicators work and practice working with paleoclimate data.

This course will explore the ocean-climate system from a geological perspective, with particular emphasis on the past 65 million years of Earth’s history. At the beginning, we will learn about the ocean-climate connection today. Then, we will explore how physical, chemical, and biological aspects of ocean and climate leave characteristic imprints in marine sediments and what are the tools available to scientists to extract and read such clues. Finally, we will assess the role of oceanic processes in the global climate by exploring past climate regimes, including past greenhouse periods, rapid climatic perturbations, and transitions to cooler climates. This class has no specific prerequisites, but some coursework in earth sciences, oceanography, and/or geochemistry might be helpful.

We will discuss basin classification schemes, isostasy, flexural and thermal subsidence, effects of mantle dynamics, basin stratigraphy, and techniques used to study sedimentary basin evolution. By determining how sedimentary basins develop and fill, we will better understand the tectonic and eustatic controls on subsidence and surficial processes.
