By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
Fine-grained material may negative effects on coastal ecosystems. Our studies suggest that the waves and currents of California are adequately energetic to transport fine-grained sediment quickly through near-shore coastal systems.
Characteristics of recent tsunami deposits, with the knowledge we have about the events that caused them, give us ways to recognize ancient deposits of this type and infer characteristics of those ancient tsunamis as well.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
