Part of Lake Forest Open Lands' Three-Lecture Series, Great Lakes, Great Issues. Coastal geologic change occurs across time from minutes to millennia and is driven by a variety of processes, including waves, water levels, and ice. Dr. Theuerkauf will explore these processes and dynamics of coastal geologic change along Western Lake Michigan. The mechanisms and implications of coastal change will be discussed as well as the technology and instruments utilized in this work, such as drones, sonar, and sediment coring. The talk will culminate with a discussion of how this research is used to improve coastal management and assess climate change. Dr. Ethan Theuerkauf, Illinois Coastal Geologist, University of Illinois
