Coastlines are dynamic, ever-changing systems that involve the interactions of the ocean, the atmosphere, and the geological processes on the land. California is located along a young, active coastline with many forces acting to shape the beaches and rocky cliffs that attract visitors worldwide. This course endeavors to explore the local shoreline with the goal of learning how all of the competing forces shape what we see. How and why do local beaches change during the year? Where does the sand come from and how has development changed the coastline? What does the future hold for the low-lying coastal areas along central California? Students will monitor beach profiles, install citizen science monitoring stations, and learn about the environmental effects on the coastline from sand mining, coastal development, and sea-level rise.
