Marine ecosystems are tightly controlled by ocean circulation and rapidly changing in response to climate change. This course discusses the processes that shape and structure ocean ecosystems, with a focus on ocean turbulence and fine-scale dynamics, and climate. The course balances overview lectures, discussion of the current and classic literature on the topic, and data analysis using observations and ocean/climate model outputs. Students participate in seminar type presentations and discussions, and work in group to present a final project based on observational data and/or ocean modeling.

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.

Students will study the chemical and physical processes involved in the sources, transformation, transport, and sinks of air pollutants on local to global scales. Societal problems such as photochemical smog, particulate matter, greenhouse gases, and stratospheric ozone depletion will be investigated using fundamental concepts in chemistry, physics, and engineering. For the class project, students will select a trace gas species or family of gases and analyze recent field and remote sensing data based upon material covered in the course. Environments to be studied include very clean, remote portions of the globe to urban air quality.

This seminar focuses on the science, engineering, policy and ethics of climate engineering -- the deliberate human intervention in the world climate in order to reduce global warming. Climate/ocean models and control theory are introduced. The technology, economics, and climate response for the most favorable climate engineering methods (carbon dioxide removal, solar radiation management) are reviewed. Policy and ethics challenges are discussed.

An introduction to natural (and some society-induced) hazards and the importance of public understanding of the issues related to them. Emphasis is on the geological processes that underlie the hazards, with discussion of relevant policy issues tied to reading recent newspaper/popular science articles. Principal topics: Earthquakes, volcanoes, landslides, tsunami, hurricanes, floods, meteorite impacts, global warming. Intended primarily for non-science majors.

The ocean and the atmosphere control Earth's climate, and in turn climate and atmospheric changes influence the ocean. We explore the circulation of the ocean and atmosphere, their chemical compositions and their interactions that make up the climate system, including exchanges of heat and carbon. We then investigate how these circulations control marine ecosystems and the biological and chemical cycles of the Earth system. The final part of the course focuses on human impacts, including changes in coastal environments and acidification and warming that result from increased atmospheric carbon dioxide. One weekly precept complements lectures.

What makes Earth habitable? How have we unraveled the mysteries of planetary interiors? Using a physics-centered approach, we'll explore a range of captivating subjects in earth and planetary science, including the origin of solar systems, tectonic plates, mantle convection, earthquakes, and volcanoes. You will learn methods to study the inner structures and dynamics of planets, not just Earth, but also celestial neighbors like Mars, Venus, Mercury, the Moon, and even exoplanets.

Humans have profoundly altered the chemistry of Earth's air, water, and soil. This course explores these changes with an emphasis on the analytical techniques used to measure the human impact. Topics include the accumulation of greenhouse gases (CO2 and CH4) in Earth's atmosphere and the contamination of drinking water at the tap and in the ground. Students will get hands on training in mass spectrometry and spectroscopy to determine the chemical composition of air, water, and soil and will participate in an outreach project aimed at providing chemical analyses of urban tap waters to residents of Trenton, NJ.

An exploration of the potential consequences of human-induced climate change and their implications for policy responses, focusing on risks to people, societies, and ecosystems. As two examples: we examine the risk to coastal cities from sea level rise and extreme heat, the scientific bases for these assessments, and measures being planned and implemented to enable adaptation. In addition, we explore local, national and international policy initiatives to reduce greenhouse-gas emissions. The course assumes students have a basic background in the causes of human-induced climate change and the physical science of the climate system.

The course covers concepts related to the chemistry of inorganic and organic materials found in the pristine and contaminated settings in the Earth surface environments, with an introduction to the modern field sampling techniques and advanced laboratory analytical and imaging tools. Different materials characterization methods, such as optical, infrared, and synchrotron X-ray spectroscopy and microscopy, will also be introduced. Field sampling and analysis of materials from diverse soil and coastal marine environments will be the focus during the second half of the semester.

Application of quantitative chemical principles to the study of natural waters. Includes equilibrium computations, carbonate system, gas exchange, precipitation/dissolution of minerals, coordination of trace metals, redox reactions in water and sediments.

Fundamentals of seismology and seismic wave propagation. Introduction to acoustic and elastic wave propagation concepts, observational methods, and inferences that can be drawn from seismic data about the deep planetary structure of the Earth, as well as about the occurrence of oil and gas deposits in the crust. Offered every other year.

This course examines the chemical composition of the oceans and the physical, chemical, and biological processes governing this composition in the past and present. Emphasis on the cycles of major elements including nutrients, carbon, and oxygen, involved in structuring marine ecosystems and regulating Earth's climate on time scales of years to millions of years. Processes and phenomena include oceanic chemical fluxes at the ocean-atmosphere and ocean-sediment interfaces, the interactions of ocean biogeochemical cycles with the physical climate system and biodiversity, and the ongoing anthropogenic perturbations.

This course explores the theory and application of the different ways that the vastness of geologic time is quantified and applied to understanding the rates and sequences of events in Earth history. It focuses on radiogenic isotope geochemistry and geochronology but also will cover other methods such as astrochronology and the geomagnetic polarity timescale. We apply these methods to understanding processes such as the origins of Earth and the Solar System; the causes of mass extinctions and climate change; plate tectonics, magmatism, and super eruptions; animal evolution; and archeology.

Course educates Geosciences and AOS students in the responsible conduct of research using case studies appropriate to these disciplines. This discussion-based course focuses on issues related to the use of scientific data, publication practices and responsible authorship, peer review, research misconduct, conflicts of interest, the role of mentors & mentees, issues encountered in collaborative research and the role of scientists in society. Successful completion is based on attendance, reading, and active participation in class discussions. Course satisfies University requirement for RCR training.
