This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
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 publication focuses on the geological framework and sedimentary processes of the Lake Pontchartrain Basin and provides links to interactive tools, regional research, and sediment data in GIS formats for display and analysis.
Topics in Coastal and Marine Sciences provides background science materials, definitions, and links to give a common context for users from a variety of backgrounds. Coastal erosion was chosen as the first topic.
We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
This web site is an outgrowth of an agreement between the USGS and the New England Aquarium, designed to summarize and make available results of scientific research. It will also present educational material of interest to wide audiences.
Overview with links to studies on the effects of human activity on the San Francisco estuary with loss of historic fresh and saltwater tidal marshes reducing habitats, introducing contaminants in waste, and creating dredging problems.
