about this Topic

erosion Coastal erosion is a national problem, with enormous economic and social consequences that affect all 30 states bordering the ocean or the Great Lakes. The geologic framework of the coastal region must be determined in order to understand the problems that must be addressed to maintain U.S. coastlines and to predict the effects of any mitigation or management plans.

Research Project
National Assessment of Shoreline Change Project
Description: Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow, and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present shoreline changes. There is also need for a comprehensive analysis of shoreline movement that is regionally consistent. To meet these national needs, 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. A primary goal of this work is to develop standardized methods for mapping and analyzing shoreline movement so that internally consistent updates can periodically be made to record shoreline erosion and accretion.

Research Project
National Assessment of Coastal Change Hazards
Description: 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. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.

Maps Showing the Stratigraphic Framework of South Carolina's Long Bay from Little River to Winyah Bay
Description: South Carolina's Grand Strand is a heavily populated coastal region that supports a large tourism industry. Like most heavily developed coastal communities, the potential for property damage and lost revenues associated with coastal erosion and vulnerability to severe storms is of great concern. In response to these concerns, the US Geological Survey (USGS) and the South Carolina Sea Grant Consortium have chosen to focus upon the Grand Strand and immediately adjacent Long Bay as a portion of Phase II of the South Carolina/Georgia Coastal Erosion Study (SC/GCES).

An Overview of Coastal Land Loss: With Emphasis on the Southeastern United States
Description: In states bordering the Gulf of Mexico and the Atlantic Ocean, vast areas of coastal land have been destroyed since the mid 1800s as a result of natural processes and human activities. The physical factors that have the greatest influence on coastal land loss are reductions in sediment supply, relative sea level rise, and frequent storms, whereas the most important human activities are sediment excavation, river modification, and coastal construction. As a result of these agents and activities, coastal land loss is manifested most commonly as beach/bluff erosion and coastal submergence.

USGS Open-File Report 99-559, Stratigraphic Framework Maps of the Nearshore Area of Southern Long Island from Fire Island to Montauk Point, New York
Description: The Nearshore Area of Southern Long Island from Fire Island to Montauk Point, New York was mapped using high-resolution profiling techniques along with surface and vibracore sampling to verify the geophysical interpretations. The goal of the investigation is to determine regional-scale availability of sand as a resource for beach nourishment programs and to investigate the role that inner-shelf morphology and geologic framework have in the erosion and morphology of southern Long Island. Maps derived from interpretation of the subbottom profiles show information on the geometry and distribution of the Quaternary sediments and the underlying Coastal Plain unconformity. This stratigraphy yields a regional framework on which explanations of present (and past) sediment movement, dispersal, and erosion processes are based.

Sidescan-Sonar Imagery of the Shoreface and Inner Continental Shelf, Wrightsville Beach, North Carolina
Description: The geologic framework and surficial morphology of the shoreface and inner shelf off Wrightsville Beach, North Carolina, were mapped using high-resolution sidescan-sonar, bathymetric, and seismic-reflection surveying techniques, a suite of over 200 diver-vibracores, and extensive sea-floor observations by divers. The inner shelf is a sediment-starved, active surface of marine erosion; modern sediments, where present, form a thin, patchy veneer blanketing Tertiary and Quaternary units.

Geologic History of Cape Cod Massachusetts
Description: Cape Cod is a sandy peninsula built mostly during the ice age and juts into the Atlantic Ocean like a crooked arm. Geologists are interested in Cape Cod because it was formed, by glaciers, very recently in terms of geologic time and because of the ever changing shore as the Cape adjusts to the rising sea. This is an online version of USGS geologist Robert Oldale's popular circular.

Publication
Seafloor Sediment Distribution Off Southern Long Island, New York
Description: The late Holocene evolution of the Fire Island barrier-island is linked directly to the geologic framework of the inner-continental shelf. Mapping results show that the modern physiography of the inner-continental shelf off southern Long Island is an expression of antecedent geology and glacial history, as well as oceanographic processes acting on the sea floor during Holocene marine transgression. The upper surface of the Cretaceous strata provided the foundation for deposition of Quaternary sediment and formed the core of a subaerial headland off Watch Hill during times of lower sea level. The modern sediment deposit was formed from erosion of both the headland areas east of Southampton and off Watch Hill and the inner-continental shelf during Holocene marine transgression.
