ESYS 10. Introduction to Earth SystemsFor non-majors and prospective Earth Systems majors. Multidisciplinary approach to how the Earth works as a system, utilizing the tools of geology, biology, and economics to understand global change on all time scales. Topics: origin of the solar system and earth, paleoclimate and climate modeling, ocean-atmosphere circulation, extinction and speciation, energy and mineral resources, economic attitudes and the environment. Case studies: acid rain, hunger and food, policy and the environment. ESYS 110. Geosphere(Same as Geological and Environmental Sciences 120.) Geological processes, from local to global, affect people and civilization. The reverse is also true; civilization is beginning to influence the geosphere. The processes experienced at the earth’s surface (catastrophic earthquakes, volcanic eruptions, and longer term atmospheric and climate changes) are linked to what goes on in the earth’s deep interior. How geochemical, geophysical, and biological processes interact over time scales ranging from 4.5 billion years to the nearly instantaneous. Topics: the origin and evolution of the atmosphere and oceans, heat flow and global tectonics and how they have changed over time, geochemical cycles, climate change, catastrophic impacts, and the roles played by organisms. Prerequisite: Geological and Environmental Sciences 1 or 2. ESYS 111. Biosphere(Same as Biological Sciences 117.) The biological causes and consequences of anthropogenic and natural changes in the atmosphere, oceans, and terrestrial and freshwater ecosystems. Topics: glacial cycles and marine circulation, greenhouse gases and climate change, tropical deforestation and species extinctions, and human population growth and resource use. Prerequisites: Biological Sciences or Human Biology core or graduate standing in any department. ESYS 112. Anthrosphere: Human Interactions with the Earth and Environment (Same as Economics 155.) The economic sources of environmental problems and the alternative policies for dealing with them (technology standards, emissions taxes, and marketable pollution permits). An evaluation of the policies addressing regional air pollution, global climate change, water allocation in the western U.S., and the use of renewable resources. The connections between population growth, economic output, environmental quality, and human welfare. Prerequisite: Economics 50. ESYS 189. Field Studies in Earth Systems(Same as Biological Sciences 206, Geological and Environmental Sciences 189.) For advanced upper division undergraduates and graduate students in Earth Systems, Biological Sciences, or Geological and Environmental Sciences. Field-based, focusing on the components and processes by which terrestrial ecosystems function. Topics from biology, chemistry, ecology, geology, and soil science. Lecture, field, and lab studies emphasize standard field techniques, experimental design, analysis of data, and written and oral presentation. Small team projects test the original questions in the functioning of natural ecosystems. Admission by application, see Time Schedule. Prerequisites: Biological Sciences 141 or Geological and Environmental Sciences 160, or equivalent. ESYS 210. Senior Seminar in Earth SystemsFocus is on communication skills, oral and written. Each student presents results of the Earth Systems internship in an oral presentation and leads a follow-up round table discussion subsequent to talk. Group project analyzing local environmental problems requires an Earth Systems approach. Peer reviews of internship papers as required. (WIM) |
