GS 128: Evolutionary History of Terrestrial Ecosystems (EARTHSYS 128, GS 228)

The what, when, and how do we know it regarding life on land¿including plants, fungi, invertebrates, and vertebrates (yes, dinosaurs)¿and how all of those components interact with each other and with changing climates, continental drift, atmospheric composition, and environmental perturbations like glaciation and mass extinction.
Terms: Win | Units: 4

GS 130: Soil Physics and Hydrology

The occurrence, distribution, circulation, and reaction of water at the surface and within the near surface. Topics: precipitation, evapotranspiration, infiltration and vadose zone, groundwater, surface water and streamflow generation, and water balance estimates. Current and classic theory in soil physics and hydrology. Urban, rangeland, and forested environments.
Terms: Aut | Units: 3 | UG Reqs: GER: DB-NatSci, WAY-SMA
Instructors: Loague, K. (PI)

GS 131: Hydrologically-Driven Landscape Evolution

Materials of the Earth and hydrologically driven landscape processes. Topics: hillslope hydrology, weathering of rocks and soils, erosion, flow failures, mass wasting, and conceptual models of landscape evolution. Current and classic theory in geomorphology.
Terms: Win | Units: 3 | UG Reqs: GER: DB-NatSci, WAY-SMA

GS 135: Field and Analytical Methods in Historical Geobiology (GS 235)

Introduction to research methods in historical geobiology. This research-based course will examine how life in ancient oceans, as recorded in the paleontological record, was affected by environmental change, as recorded in the geochemical record. Students will collect paleontological and geochemical data from a measured stratigraphic section in the western United States. In lab, students will learn low temperature geochemical techniques focusing on the cycling of biogeochemical elements (O, C, S, and Fe) in marine sediments throughout Earth history. This is a lab-based course complemented with lectures. Preference will be given to students able to attend a four-day field trip at the end of spring break to measure the stratigraphic section and collect samples.
Terms: Spr | Units: 4
Instructors: Sperling, E. (PI)

GS 135A: Historical Geobiology Field Trip

Field trip to a sedimentary succession of geobiological interest. Students will measure the stratigraphic section, describe fossils and trace fossils, and collect samples for geochemical analysis. Offered over spring break.
Terms: Spr | Units: 1
Instructors: Sperling, E. (PI)

GS 135A: Historical Geobiology Field Trip

Field trip to a sedimentary succession of geobiological interest. Students will measure the stratigraphic section, describe fossils and trace fossils, and collect samples for geochemical analysis. Offered over spring break.

GS 150: Senior Seminar: Issues in Earth Sciences

Focus is on written and oral communication in a topical context. Topics from current frontiers in earth science research and issues of concern to the public. Readings, oral presentations, written work, and peer review.
Terms: Aut | Units: 3

GS 151: Sedimentary Geology and Petrography: Depositional Systems

Topics: weathering, erosion and transportation, deposition, origins of sedimentary structures and textures, sediment composition, diagenesis, sedimentary facies, tectonics and sedimentation, and the characteristics of the major siliciclastic and carbonate depositional environments. Required Lab Section: methods of analysis of sediments in hand specimen and thin section. Field trips. Prerequisites: 1, 102, 103.
Terms: Spr | Units: 4 | UG Reqs: GER: DB-NatSci

GS 163: Introduction to Isotope Geochemistry (GS 263)

Stable, cosmogenic, and radiogenic isotopes; processes that govern isotopic variations. Application of isotopes to geologic, biologic, and hydrologic questions. Major isotopic systems and their applications. Simple modeling techniques used in isotope geochemistry.

GS 170: Environmental Geochemistry (EARTHSYS 170, GS 270)

Solid, aqueous, and gaseous phases comprising the environment, their natural compositional variations, and chemical interactions. Contrast between natural sources of hazardous elements and compounds and types and sources of anthropogenic contaminants and pollutants. Chemical and physical processes of weathering and soil formation. Chemical factors that affect the stability of solids and aqueous species under earth surface conditions. The release, mobility, and fate of contaminants in natural waters and the roles that water and dissolved substances play in the physical behavior of rocks and soils. The impact of contaminants and design of remediation strategies. Case studies. Prerequisite: 90 or consent of instructor.
