ES23A:
Implications of Climate Change for Mid- to High-Latitude Coastal Systems

Submit an Abstract to this Session

Session ID#: 6363

Session Description:
Snow, ice and winter storms are important factors affecting geomorphic change in mid to high-latitude coastal systems. For example, ice can erode a shoreline. Freeze/thaw processes can weather rock platforms. Conversely, snow/ice can protect beach sediments from erosion. Changes in storm frequency and/or intensity and/or timing may alter the rate and/or nature of geomorphic evolution in mid and high-latitude coastal systems found throughout Canada and the US, including the Great Lakes. As our climate changes, the roles of snow, ice, winter storms and other controls on coastal geomorphic evolution will change too. For example, less coastal ice may result in more wave energy propagating to shore. Controls like rainfall and vegetation may change. The purpose of this session is to explore the implications of changes in controlling variables on the evolution of mid to high-latitude coastal systems. Papers can focus on systems (e.g., barrier islands) or system components (e.g., dunes).
