The Case for Managed Open Water Disposal of Sediments Containing Low Levels of Dioxin
Between 6 and 8 million cubic yards of material is dredged annually from the 240 miles of federal channels and approximately one million linear feet of berthage of the Port of New York/New...
Geological Assessment of Offshore Sand Deposits
The United States Atlantic and Gulf of Mexico continental shelf contains large numbers of surficial sand deposits. The search for sand resources for metropolitan construction and coastal...
An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...
The Physical Evolution of a Wetland Restoration
Since European colonization, San Francisco Bay has lost 95 percent of its original wetlands. The success of recent efforts to restore wetlands throughout California and the U.S. cannot...
New Directions for NOAA/NS&T Program: Historical Reconstruction of Sediment Contamination Using Dated Cores
Sediment cores sampled in coastal and estuarine areas can be used to reconstruct historical trends in sediment contamination. The sediment cores have to be undisturbed in order to obtain...
Responses of Benthic Macrofauna to Phaseout of Sewage Sludge Disposal in the Inner New York Bight
From 1924 through 1987, sewage sludge was dumped at the '12 mile site' 22 km off northern New Jersey in the inner New York Bight. Inputs in the early 1980s were,...
Beach Erosion in the Town of Jupiter Island: Causes and Remedial Measures
St. Lucie Inlet, located on the lower east coast of Florida, was cut across a barrier island in 1892 and jetties were constructed on the north and south sides of the inlet in 1926 and...
A Study of the Impact of the Dumping of Spoil on Beach Processes
The amenity value of beaches along the North East coast of England is reduced because of the continuing practice of dumping colliery spoil directly onto the beaches for dispersal by the...
Sediments and Quaternary Study of the Coastal Lagoon of Unare (Venezuela)
The coastal Lagoon of Unare is located in the N.E. of Venezuela (62? 12' - 65? 25' W/10? 04' - 10? 08' N), it is 26 km long and 6 km...
3-D Modelling of Suspended Sediment Transport
A three-dimensional finite difference model has been developed for the numerical simulation of the physical process of horizontal and vertical convection, horizontal and vertical diffusion...
Shore Protection Conflicting Objectives in Decision Making
Shore protection, in an era of rising sea levels and declining sediment budgets, is emerging as a priority item in coastal management. Yet to the traditional conflict between man and nature...
Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...
Coastal Erosion in Ghana: Causes, Patterns, Research Needs and Possible Solutions
The pattern of coastal erosion in Ghana is described. The causes for spatial differences in the erosional rates on the shoreline are identified as coming from a combination of natural...
Reactivation of the Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) Facility
The Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) was run by the Environmental Protection Agency (EPA) from 1974 to 1988. This open-air tank was used to test...
Results from Selected Oil-Spill Response Research
Recent large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil-spill response capabilities. The Minerals Management Service...
Coastal Dune Blowouts?Dynamics and Management Implications
New approaches to coastal dune management have been advocated recently, including dune grading and dune destabilization. A management concern in the case of destabilization involves the...
Ecological and Geomorphic Impact of the Destruction of a Coastal Sand Dune System in a Sand Spit
Two main effects of the destruction of the coastal dunes at the sand spit of Estero de Punta Banda, (B.C., Mexico) were studied comparing unaltered and altered adjacent zones, The amount...
Environmental Impact of a Power Plant: A Case From a Coastal Area in Venezuela
These are the results of a eight years study in which the ecological effects of Planta Centro power plant were assessed. Many aspects were included in this study, but we concentrate here...
Mercury-Contaminated Sludge Treatment by Dredging in Minamata Bay
To eradicate Minamata disease, caused by sewage containing methyl mercury accumulating in fish and shell-fish through the food cycle, a large-scale sediment disposal project was conducted...
