EARTHSYS 104: The Water Course (GEOPHYS 70)

The Central Valley of California provides a third of the produce grown in the U.S., but has a desert climate, thus raising concerns about both food and water security. The pathway that water takes rainfall to the irrigation of fields (the water course) determines the quantity and quality of the available water. Working with various data sources (remote sensing, gauges, wells) allows us to model the water budget in the valley and explore the way in which recent droughts and increasing demand are impacting freshwater supplies.
Terms: Win | Units: 3 | UG Reqs: GER: DB-NatSci, WAY-AQR, WAY-SMA

GS 185: Volcanology (GS 285A)

For juniors, seniors, and beginning graduate students. Eruptive processes that create volcanic deposits and landforms; shield, stratocone, and composite volcanoes, lava dome fields; calderas. Control of magma viscosity and water content on eruptive style. Fluid dynamic controls on the characteristics of lavas and pyroclastic flows. Submarine and subglacial eruptions and interaction of magma with groundwater. Rhyolitic supereruptions and flood basalts: effects on climate and atmospheric chemistry, relation to extinction events. Volcanic hazards and mitigating risk. Geophysical monitoring of active volcanoes. Volcanic-hosted geothermal systems and mineral resources. Those taking the class for 4 units will complete a 3-hour weekly lab that emphasizes recognizing types of lavas and products of explosive eruptions in hand specimen and thin section. Prerequisite: 1, for those taking the course for 3 units; 103 and 104 or equivalent for those taking the course for 4 units.
