Storms, Sea Level, and Shifting Seas: Reconstructing Past Coastal Hazards from Marine Archives
Session ID#: 254196
Session Description:
Coastal communities and ecosystems around the globe are highly vulnerable to both event-scale and long-term climate-related hazards imposed by changing sea level, tropical cyclone activity, ocean circulation, and physical seawater properties (e.g., temperature, salinity, and carbonate chemistry). Shifting environmental baselines are driving the continuing degradation of the unique coastal marine ecosystems that help to buffer the impacts of natural hazards. By providing information about where, when, and why coastal marine hazards have occurred in the past, we can better understand the vulnerability of natural and human coastal communities to both long-term environmental change and punctuated natural hazards in the future. This session will focus on applications and development of proxies for reconstructing coastal hazards and related phenomena, including, for example, tropical cyclones, tsunamis, sea-surface temperature and salinity, oscillatory climate patterns and teleconnections, and ocean acidification. We welcome submissions that advance the use of well-established and novel proxy archives to understand the magnitudes, causes, and impacts of event-scale and long-term climate variability on societally relevant timescales (decades to millennia).
