Berkeley: Department of Earth and Planetary Science The field of Earth and Planetary Science offers a rich variety of research targets and educational opportunities for students. The research carried out in the department, and the courses offered, treat topics encompassing the structure and composition of the earth's solid and fluid cores, the constitution of the earth's crust, the workings of the earth's oceans and atmosphere, and the evolution of the earth and other planets over billions of years. Researchers and students in this field are driven by fundamental curiosity about the past and present states of the earth and planets, seek to understand the origin of earthquakes and mineral resources, the workings of volcanoes, changes in the earth's climate and environment, and the impacts of global changes on society. The tools of Earth and Planetary Science are basic concepts of physics, chemistry, biology, applied mathematics and statistics, and advanced instruments that can be used to characterize geologic processes and materials. These instruments include remotely operated probes of the oceans and atmosphere, spacecraft, seismometers, GPS stations, mass spectrometers, synchrotrons, electron microscopes, and even the traditional hand lens, compass, pick and hammer. Work in Earth and Planetary Science attracts theoreticians eager to apply their conceptual knowledge to "real life" problems, as well as enthusiasts of field work in remote areas of the globe, talented physical, chemical or biological sensor developers, and wizards of computer modeling. The Department of Earth and Planetary Science has a long tradition of posing and answering intellectually fascinating questions about the Earth-asking whether the continents stay fixed or move around, what the history of life has been and why, how the landscape we know has come to be, and why there are earthquakes and volcanoes. Berkeley's Department of Earth and Planetary Science was the first major center of academic geology in the western United States and has been involved in many of these scientific developments. Berkeley geologists made the first detailed study of a major earthquake, developed potassium-argon dating — the most important method for finding the ages of rocks, brought the rigor of thermodynamics into geology, and discovered the evidence that a comet impact killed the dinosaurs. As concern has grown in recent years over environmental deterioration and depletion of resources, our focus has broadened to include matters of urgent social relevance. Many departments at Berkeley are concerned with environmental questions, focusing on policy, management, economics, engineering, and social concerns, but all depend for the validity of their conclusions upon a correct scientific understanding of Planet Earth. It is up to geologists, geochemists, and geophysicists to provide that understanding, and at Berkeley these practical concerns now stand alongside the more academic questions in a double focus of the Department of Earth and Planetary Science. The interests of the faculty cover a broad range of earth sciences. The traditional fields of petrology, mineralogy, mineral resources and structural geology are represented. Solid earth geophysics includes a unique combination of expertise in seismology, mineral physics and geodynamics. Our earthquake and tectonics program benefits from the resources made available through the Berkeley Seismological Laboratory. A vigorous program in geomorphology and surface processes attracts many students. Recently we have added a marine geophysics program, an atmospheric science program and most recently a planetary science program, with links to programs in the Departments of Chemistry, Astronomy, Geography and Environmental Science and Policy Management. Additional resources for research are available through the Center for Atmospheric Science and the Center for Integrated Planetary Science. We are making progress in bringing geology and geophysics closer by making the former program more quantitative and the latter more based in geological observations. Resources for Geochemists include the Center for Isotope Geochemistry and the Berkeley Geochronology Center. Some of our faculty have strong collaborations with the Earth Science Division at the Lawrence Berkeley National Laboratory. The Department of Earth and Planetary Science offers a Ph.D. program as well as a Master of Arts and a Master of Science option, with the possibility of specializing in any of the areas of expertise of our faculty. The department offers the graduate student the opportunity to develop skills in theoretical and experimental analysis, and to blend these skills with careful description in the field and in the laboratory. The central objective of the graduate program is to encourage creative thinking and to develop the capacity for independent and original research.

At these timescales, the study of Earth's atmosphere encompass interactions with the biosphere, and how one species, humans, alter the natural cycles and long-term trajectory of the planet. Atmospheric science is therefore intrinsically interdisciplinary, with chemistry, physics, mathematics, biology, geology, and ecology all core disciplines. The Berkeley Atmospheric Sciences Center is a multi-college unit at UC Berkeley, with the goal to broaden the atmospheric sciences beyond its traditional boundaries to embrace the biogeochemical frontier and the human dimension. The Center facilitates communication and integration across these traditional boundaries. In doing so, we aim to define a new paradigm for investigating changes in the atmosphere by integrating the microscopic mechanisms of chemical, physical, and biological processes with large-scale ecological and geological interactions between the geosphere, biosphere, and oceans, and how these interactions alter atmospheric composition. Our core and affiliate faculty members are drawn from the various core disciplines, but with a common interest in the atmospheric sciences.

Currrent projects: -carbon cycle research—how carbon sinks/sources vary annually and variation of atmospheric gasses. Studying a specific forest in CA, also efforts with NASA in a global flux network 3) John C.H. Chiang Department of Geography Research Interests: I study the dynamics of climate, with a focus on the tropical atmosphere and oceans where I think the most interesting recent advances in the field have originated. Much of my work is motivated in trying to understand the nature of variations in the regional and global climate on seasonal and longer timescales. I am very much interested in developing a theory for how El Nino influences climate over the remote tropics; discovering mechanisms of middle and high latitude influence on the tropical climate; and understanding the coupled interactions of the marine Intertropical Convergence Zone (ITCZ) and cold tongue. Recently I have become intrigued with the problem of climate changes during the Holocene and the last glacial period, and in particular on how the tropical climate and the ITCZ may be involved. I have also worked on the climate-society interface, in proposing a linkage between an ancient indigenous Andean climate forecasting method to El Nino. I use a variety of research tools, from statistical analysis of climate data, to developing simple models, to using more complex models of the atmosphere and ocean. 4) Kurt M. Cuffey---this guy has a good webpage…very eloquent and well thought out description of what he does… Department of Geography and Department of Earth and Planetary Sciences Research Interests: The global physical environment is a vast and complex machine composed of numerous interconnected systems capable of dramatic change over brief intervals of time. A solid understanding of the character and dynamics of this machine can explain a diversity of engaging geographical phenomena, from the aesthetically stunning views on a high Sierra Nevada mountain summit to the devastating loss of life and property resulting from land- slides and floods. The purpose of my scholarship is to design, improve, evaluate, and enjoy such explanations. Two complementary approaches in this pursuit are (1) to achieve a rigorous physically-based understanding of environmental processes and sys-tem dynamics, and (2) to reconstruct the remarkable "natural experiments" of Earth's en-vironmental history. I use both approaches. Constraints on time, technology, and brainpower have forced me, like most scholars, to the bittersweet reality of specialization; my research efforts emphasize environmental change of polar regions, with a focus on glaciologic problems. The choice of polar glaciology reflects the unique and powerful contributions that this subdiscipline makes to en-vironmental change research. Ice core reconstructions of environmental history offer the most comprehensive, varied, and high-resolution view yet achieved of past environments. The ice sheets themselves are a major control on global sea level and albedo, and on high-latitude atmospheric and oceanic circulations, and on physical landscape characteristics. No other topographic features of this size and importance are changeable on such short time scales. I use a quantitatively rigorous and novel blend of geophysical and geochemical techniques to address questions that are important in this context: How have climatic temperature and atmospheric greenhouse gas concentrations covaried in the past? What is the tempo and magnitude of climate changes in polar regions? What determines the isotopic composition of precipitation? How have the great ice sheets changed in the past, and how will they change in the future? How do they flow? How are microphysical processes in ice manifest at the scale of whole glaciers and ice sheets? In addition to these major research themes, I also do some work on biogeography and temperate geomorphology. I very much enjoy the breadth and diversity of scholarship in the Berkeley Geography Department (my home department) and also am affiliated with the Department of Earth and Planetary Science. 5) John Harte Department of Environmental Science, Policy, and Management Research Interests: My areas of research include causes and consequences of climate change with an emphasis on the study of climate-ecosystem feedback processes, theoretical ecology with an emphasis on elucidating relationships between community structure and functional integrity of ecosystems, causes and consequences of declining biodiversity, biogeochemical processes and their disruption, and the role of ecological integrity in human society. Currect project: warming an area of subalpine meadow…measuring changes…positive feedback mechanisms. 6) Robert Rhew Department of Geography Interests: terrestrial-atmosphere exchange of trace gases, atmospheric chemistry and composition, halogen biogeochemistry, stratospheric ozone depletion issues Humans have modified the chemical composition of the earth’s atmosphere through emissions of radiatively and environmentally active compounds. Consequently, our society faces a triumvirate of interrelated global atmospheric chemistry issues: stratospheric ozone depletion, the enhanced greenhouse effect, and the changing capacity of the atmosphere to oxidize pollutants. The primary players in these atmospheric chemistry problems are the trace gases, which account for only a fraction of a percent of the total atmospheric composition. My field of research is trace gas biogeochemistry, which involves elucidating the interactions between the atmosphere, biosphere, pedosphere, and hydrosphere. My work involves laboratory and field-based measurements in different terrestrial ecosystems, such as coastal salt marsh, chaparral, desert, tundra, boreal forest, grassland, and temperate forest. My research seeks to identify natural terrestrial sources and sinks of important trace gases, to quantify their fluxes, and to determine the environmental and biological controls on those fluxes. Recent innovations in measurement technology and analytical design have allowed for the precise and accurate analysis of gases at the parts- per-trillion concentration levels, opening up a wealth of research opportunity to study their biogeochemical cycles. Major questions remain in the global budgets of many trace gases, including the methyl halides (CH 3Br, CH3Cl, CH3I), chloroform (CHCl3), nitrous oxide (N2O), methane (CH4), carbonyl sulfide (OCS), and methyl chloroform (CH3CCl3). Understanding their interaction with the biosphere will require controlled laboratory studies, extensive field work, and novel techniques using stable isotope tracers.
