Open-File Report 50 presents and describes a database of geochronological information for coastal deposits of the US Atlantic and Pacific coasts, as well as for sites from the Pacific coast of South America. This database represents a synthesis of nearly forty years of study conducted by John F. Wehmiller and students in the Department of Geological Sciences, University of Delaware, as well as many collaborating colleagues.
Caught in a federal-state funding standoff that one Delaware official said could put lives at risk, widely used public tide and weather monitors at more than 10 Delaware River and Bay sites face shutdown by September.
The National Oceanic and Atmospheric Administration posted the shutdown notice with little fanfare for its local Physical Oceanographic Real-Time System (PORTS) sites. Few outside of river and bay maritime interests were aware of the threat on Thursday.
Marshes reduce storm flooding, filter contaminants out of water and provide habitat for birds, fish and other wildlife. However, these environmentally critical areas have decreased in extent along the coast in recent decades, and UD researchers are working to better understand the factors that affect marsh stability—especially in the face of sea level rise.
