Study addresses questions and concerns related to limited sand resources along the Louisiana shelf and their implications to long-term relative sea-level rise and storm impacts, using newly acquired geophysical and vibracore data.
Presentation of maps of the seismic properties of North America and the surrounding ocean basins compiled from seismic refraction and reflection data, earthquake studies, and surface wave analyses showing crustal thickness and geologic provinces.
USGS project to understand coastal evolution and modern beach behavior; to identify and model the physical processes affecting coastal ocean circulation and sediment transport; and to identify sediment sources and construct a regional sediment budget.
Presentation that the location of Chesapeake Bay may have been predetermined by a Eocene bolide, an extraterrestrial body, impacting the Earth in the vicinity of the Delmarva Peninsula at high velocity and exploding to create a large crater.
