ENVS-135 Coastal Geology
Coastal environments are among the most dynamic natural systems. Approximately half (4 billion) of the world's population is located within 100 kilometers of the coast. Understanding how these coastal systems react to sea-level rise, shifting storm patterns, and population growth requires a comprehensive grasp of physical processes that occur on scales ranging from seconds to millennia, and across areas as small as a few centimeters to hundreds of kilometers. By examining the dynamic processes that shape the margins of continents and islands and tracing the recent history of specific shorelines, we can better predict future geomorphic shifts and develop strategies to adapt to changing coastal landscapes and ecosystems. During a required day-long field trip (scheduled on a weekend or school holiday), we will apply classroom knowledge to analyze a diverse group of landforms and to interpret their modern evolution. NOTE: two field trips will be offered outside of class meeting time, and one is required for a significant portion of the final course grade. This course adopts a process-based approach to studying coastal systems, covering a range of topics essential to understanding shoreline dynamics and evolution. Key themes include coastline evolution, focusing on geological forces responsible for erosion, deposition, sea-level changes, glaciation, and biological influences.
