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.

Examines the use of stable isotope measurements to investigate important biogeochemical, environmental, and geologic processes, today and over Earth history. Introduction to terminology, basic underlying principles, measurement techniques, commonly used analytical and computational approaches for analyzing data, followed by a review of typical applications of the isotope systems of carbon, oxygen, nitrogen, and other elements. Lectures by the instructor, problem sets, numerical modeling assignments, student presentations and a final student paper based on readings from the scientific literature.

This course presents a treatment of the physical and chemical processes that shape Earth's surface, such as solar radiation, deformation of the solid Earth, and the flow of water (vapor, liquid, and solid) under the influence of gravity. In particular,the generation, transport, and preservation of sediment in response to these processes is studied in order to better read stories of Earth history in the geologic record and to better understand processes involved in modern and ancient environmental change.

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.

The ocean and the atmosphere control Earth's climate, and in turn climate and atmospheric changes influence the ocean. We explore what sets the temperature of Earth's atmosphere and the connections between oceanic and atmospheric circulations, including exchanges of heat and carbon. We then investigate how these circulations control marine ecosystems and the cycling of chemicals in the ocean. The final part of the course focuses on human impacts, including changes in coastal environments and the acidification resulting from increased atmospheric carbon dioxide.

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.

Minerals are the fundamental building blocks of the Earth. Their physical, chemical, and structural properties determine the nature of the Earth and they are the primary recorders of the past history of the Earth and other planets. This course will provide a survey of the properties of the major rock-forming minerals. Topics include crystallography, crystal chemistry, mineral thermodynamics and mineral occurrence. Emphasis will be on the role of minerals in understanding geological processes. Laboratories will focus on developing an understanding of crystallography, structure-property relationships, and modern analytical techniques.

An Introduction to Earth and Planetary Physics. Planetary formation (accretion, cooling, heat transport) and evolution (mantle convection, deformation, plate tectonics). Rheology, and mineral physics (melting and differentiation). Techniques include gravity, magnetism, seismology and geodynamics, Taught in the context of the terrestrial planets (Earth, Mars and Venus).

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.

A yearlong survey, in sequence, of fundamental papers in the geosciences. Topics in 505 (Spring) include the origin and interior of the Earth, plate tectonics, geodynamics, the history of life on Earth, the composition of the Earth, its oceans and atmospheres, past climate. Topics in 506 (Fall) include present and future climate, biogeochemical processes in the ocean, geochemical cycles, orogenies, thermochronology, rock fracture and seismicity. A core course for all beginning graduate students in the geosciences.

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.

This course provides the chemical background to understand many of today's most important environmental issues. Topics include atmospheric pollution, the ozone hole, the greenhouse effect, ocean acidification, acid mine drainage, and coastal dead zones. Overall, the course focuses on a quantitative understanding of the chemistry of the atmosphere and natural waters. Students will use the chemical equilibrium model Minteq to study specific examples related to water quality issues.

Natural gas phase and heterogeneous chemistry in the troposphere and stratosphere, with a focus on elementary chemical kinetics; photolysis processes; oxygen, hydrogen, and nitrogen chemistry; transport of atmospheric trace species; tropospheric hydrocarbon chemistry and stratospheric halogen chemistry; stratospheric ozone destruction; local and regional air pollution, and chemistry-climate interactions are studied.
