Global Arc

Introduction to modern geologic field methods, with local and regional problems studied from a residential base camp. One option is the five week University of Houston-Yellowstone Bighorn Research Association (YBRA) course based in Red Lodge, Montana, run by the University of Houston. Alternatively, students may attend field courses offered by other institutions after obtaining approval from the Undergraduate Work Committee of the Department of Geosciences. Financial aid is available through the Geosciences Department.

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).

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.

This class discusses fundamental aspects of Earth's climate with a focus on the fundamental atmospheric processes that render Earth "habitable," and how they may respond to the forcing originating from natural (such as volcanoes) and anthropogenic (such as emission of carbon dioxide and ozone-depleting gases) processes.

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.

Covers topics including origin of elements; formation of the Earth; evolution of the atmosphere and oceans; atomic theory and chemical bonding; crystal chemistry and ionic substitution in crystals; reaction equilibria and kinetics in aqueous and biological systems; chemistry of high-temperature melts and crystallization process; and chemistry of the atmosphere, soil, marine, and riverine environments. The biogeochemistry of contaminants and their influence on the environment will also be discussed. Two 90-minute lectures. Prerequisite: one term of college chemistry or instructor's permission.

This course introduces students to the evolution of life and mass extinctions based on a broad survey of major events in Earth history as revealed by the fossil record. Concepts and techniques of paleontology are applied to all aspects, including colonization of the oceans, invasion of land, mass extinctions and evolutionary radiations. The roles of major catastrophes in the history of life are evaluated, including meteorite impacts, volcanism, climate change, and oceanic anoxia. One three-hour lecture. Prerequisite: One 200 level or higher GEO course.

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 one example: we examine the risk to coastal cities from sea level rise, 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. Two 90-minute lectures, one precept.

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. Prerequisite: CHM 202.

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 are 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. Prerequisites: MAT 104, PHY 103, CHM 201, or equivalents.Two lectures, required spring break field trip, students do lab work as groups on their own time
