ENV 210 offers an introduction to the scientific and technological dimensions of the nexus of global environmental problems: climate change, the carbon cycle, biodiversity loss, and the provision of food and water. The course will provide the scientific foundations to understand each of these complex environmental problems, first in isolation and then in its interaction with the others. Students will be able to understand major scientific reports on the interacting environmental challenges and assess their possible future trajectories, their potential solutions, and their implications for a growing human population on a finite planet.

Which human activities are changing our climate, and does climate change constitute a major problem? We will investigate these questions through an introduction to climate processes and an exploration of climate from the distant past to today. We will also consider the impact of past and ongoing climate changes on the global environment and on humanity. Finally, we will draw on climate science to identify and evaluate possible courses of action. Intended to be accessible to students not concentrating in science or engineering, while providing a comprehensive overview appropriate for all students.

This course introduces solid Earth system science, quantifying underlying physical and chemical processes to study the formation and evolution of Earth through time. We discuss how these processes create and sustain habitable conditions on Earth, including feedbacks and tipping points as recorded in the geologic record. Topics include stellar and planetary formation, plate tectonics, seismology, minerals/rocks, the geologic timescale, natural resources, the hydrologic cycle and sedimentation, paleoclimatology, and the "Anthropocene." Students will apply these topics to the recent past to assess human impact on the environment.

This course discusses the processes that control Earth's climate - and as such the habitability of Earth - with a focus on the atmosphere and the global hydrological cycle. The course balances overview lectures (also covering topics that have high media coverage like the 'Ozone hole' and 'Global warming', and the impact of volcanoes on climate) with selected in-depth analyses. The lectures are complemented with homework based on real data, demonstrating basic data analysis techniques employed in climate sciences.

Earth records its own history in rocks, chronicling catastrophes like meteorite impacts, gradual processes with outsized consequences such as erosion, and pivotal turning points like global glaciation and mass extinction. Imagine Earth's 4.5 billion year history as millions of overlapping crime scenes with much of the evidence wiped away. In this class, you are the forensic detective, learning the observational and analytical techniques needed to decode the interacting forces that created the planet we know today and learning to recognize what we still do not understand.

Students will learn about climate change, climate projections and mitigation strategies. Student will analyze climate data and future scenario models, evaluate potential climate change and impacts on the Earth system (warming, rainfall), explore mitigation strategies, costs, barriers and benefits (changes in lifestyle, negative emissions, solar radiation management etc.). The course will introduce students to climate data analysis using Jupyter Notebooks.

This course focuses on the relationship between climate and weather events: each weather event is unique and not predictable more than a few days in advance, large-scale factors constrain the statistics of weather events, those statistics are climate. Various climatic aspects will be explored, such as the geographic constraints, energy and water cycling, and oceanic and atmospheric circulation, solar heating, the El Niño phenomenon, ice ages, and greenhouse gases. These climate features will be used to interpret the statistics of a number of weather events, including heat waves, tropical cyclones (hurricanes and typhoons) and floods.

The vertebrate animals that are alive today can all trace their history back to a worm-like organism that lived more than 500 million years ago. Since then, vertebrates have diversified into an incredible number of forms across almost every environment on Earth, and this diversification is recorded in the geological record. This course examines the complex evolution of vertebrates in the context of an ever-changing planet. By the end of the class, students will be able to understand where some of our anatomical features came from, how features of other vertebrates evolved, and how they have changed over the last 500 million years.

Students will gain the foundational tools needed to conduct geosciences research. Python will be introduced and used throughout for data exploration, visualization, and analysis. Topics include applied statistics, experimental design, regression, spectral analysis, and random sampling methods. Lectures will include a mix of theory and programming demonstrations, interspersed with field and lab sessions to collect data from various geosciences topic areas (e.g., ocean and atmospheric sciences, sedimentology, remote sensing).

An intensive introduction to isotopic analyses in the Earth sciences. Students will learn the fundamentals of isotope abundance and isotope ratio mass spectrometry through lectures and laboratory rotations with hands-on training in a wide range of analytical techniques. The course is oriented towards upper-level undergraduate students interested in pursuing laboratory research in geological, biological, and environmental sciences as part of their JP or ST as well as graduate students in the natural and applied sciences.

The study of microbial biogeochemistry and microbial ecology. Beginning with the physical/chemical characteristics and constraints of microbial metabolism, we will investigate the role of bacteria in elemental cycles, in soil, sediment and marine and freshwater communities, in bioremediation and chemical transformations.

This class will introduce students to the modern study of the structure, composition, and evolution of the Earth's interior. We will integrate findings from geophysical observations, laboratory experiments, and computational models to develop a holistic picture of the large-scale behavior of our planet. The course will be divided into four major sections: 1) origin and composition of the Earth; 2) physical and chemical properties of Earth materials; 3) global Earth structure; 4) Earth dynamics. The course will introduce current topics and the latest findings from the scientific literature.

This course covers atomistic modeling fundamentals and the applications to the study of material properties. Topics include intro to clusters, quantum mechanics basics, Hartree-Fock, density function theory, molecular dynamics, and machine learning potential. Each topic contains both theory and hands-on software tutorials of deriving material properties using available softwares (e.g., VASP, PySCF, LAMMPS, DeePMD-kit). Students gain experience applying atomistic modeling to their individual areas of research interest. Individual projects are developed by students throughout the semester.

This course is for those who want to turn data into models and subsequently evaluate their uniqueness and uncertainty. Three main topics are: 1. Elementary inferential statistics, 2. Model parameter estimation via matrix inverse methods, and 3. Time series analysis and Fourier spectral density estimation. Problem sets and computer programming exercises form integral parts of the course. While the instructor's and textbook examples will be derived mostly from the physical sciences, students are encouraged to bring their own data sets for discussion. Prior programming experience in MATLAB is helpful but not required.

The study of the oceans as a major influence on the atmosphere and the world environment. The contrasts between the properties of the upper and deep oceans; the effects of stratification; the effect of rotation; the wind-driven gyres; the thermohaline circulation.

An advanced introduction to setting up and solving boundary value problems relevant to the solid earth sciences. Topics include heat flow, fluid flow, elasticity and plate flexure, and rock rheology, with applications to mantle convection, magma transport, lithospheric deformation, structural geology, and fault mechanics.

The senior thesis (498-499) is a year-long project in which students complete a substantial piece of research and scholarship under the supervision and advisement of a Princeton faculty member. While a year-long thesis is due in the student's final semester of study, the work requires sustained investment and attention throughout the academic year. Required works-in-progress submissions, their due dates, as well as how students' grades for the semester are calculated are outlined below. Additionally, we encourage students to meet with their advisor and/or attend group meetings at least 5 times in the semester.

A survey of fundamental papers in the Geosciences. Topics include present and future climate, biogeochemical processes in the ocean, geochemical cycles, orogenies, thermochronology, Earth structure and mechanics, and seismicity. This is the core geosciences graduate course.

Structure and composition of terrestrial atmospheres. Fundamental aspects of electromagnetic radiation. Absorption and emission by atmospheric gases. Optical extinction of particles. Roles of atmospheric species in Earth's radiative energy balance. Perturbation of climate due to natural and antropogenic causes. Satellite observations of climate system.

Each week, students read one research paper and discuss with faculty. The instructor provides additional information such as the historical context, motivation of research, and impact on the field. The papers selected differ from year to year, with a semester's papers organized around either: a collection of "great papers" that are seminal in the field of AOS; a collection of recent high impact papers; and papers discussing a specific topic. The detailed analysis of the research papers also helps students familiarize with the process of distilling essential results for publication.

Tensor calculus is a language used to describe physical phenomena in fluid dynamics, continuum mechanics, electromagnetism, and general relativity. The course explores the mathematical background for geometrical descriptions of tensors and their calculus. Students need to be familiar with multivariate calculus and partial differential equations.
