MG41A:
Response of Coastal Sedimentary Systems to Anthropogenic Alterations and Climate Change I


Session ID#: 11369

Session Description:
Coastal environments, located at the interface between terrestrial and marine processes, are becoming more vulnerable due to climate change and human activities.  These dynamic sedimentary systems operate through a series of feedback loops responding to natural and anthropogenic alterations. The responses of these systems vary widely over a range of spatial and temporal scales, and may be observed as geomorphological changes and/or preserved within the sedimentary record.  Increasing our understanding of how these systems respond, or have responded in the past to natural and anthropogenic changes will be critical to the future sustainability of valuable coastal ecosystems.  

This session will broadly address sedimentation, and sediment dynamics of coastal systems such as estuaries, beaches, marshes, and wetlands with a focus on the linkages between how environmental and sedimentary process are preserved within the geologic record. Emphasis will be placed on how these coastal systems respond to natural changes (e.g. climatic, tectonic, sea level, episodic storms) and anthropogenic alterations to the system, and how these changes influence sedimentary dynamics and ultimately are preserved within the geologic record. We encourage submissions that highlight these linkages through studies utilizing high-resolution geophysics, sediment and stratigraphic analyses, field observations, and modeling among others.
