Sedimentary characteristics of 228 tsunami deposits, drawn from published accounts, for interpreting prehistorical, historical, and modern tsunami deposits, and for the development of criteria to identify tsunami deposits in the geologic record.
Modified version of paper by F.T. Manheim and A.G. McIntire, Civil Engineering Practice, Vol. 13, No. 1, pp. 35-48 (1998). A new shoreline file has been created for Boston Harbor by digitizing and combining the most recent charts.
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.
This updated global inventory reports on natural gas hydrate recovered or inferred from geophysical, geochemical, or geological evidence. Includes links to world location maps, inventories, references and posters. Also in PDF format files.
Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
Information on video and still photography used to supplement laser altimetry measurements of the coast. The photography is used for recognizing geomorphic and cultural features impacted by storms. Links to photo collections of hurricanes and El Nino.
Airborne scanning laser surveys (LIDAR) are used to obtaining data to investigate the magnitude and causes of coastal changes that occur during severe storms. Links to examples of coastal mapping during specific hurricanes.
Description of three types of severe coastal storm impacts: hurricane impacts on the southeast U.S., extra-tropical storm impacts on the U.S. west coast during El-Nino winters, and 'northeaster' impacts on the U.S. east coast.
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.
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.
Regional studies mapping the seafloor sedimentary character and assessing marine sand and gravel resources around the United States, to inform beach nourishment and coastal restoration, benthic habitat and sediment transport studies
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.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii.
