OTEC: At the Brink of Commercial Reality?
The development of ocean thermal energy conversion (OTEC) has traditionally been a question of technological feasibility and economics. Recent research and design developments, however,...
A Benthic Environmental Evaluation Protocol for a New Municipal Marine Outfall
Concurrent with siting studies to relocate a 72 mgd secondary outfall diffuser in deep water (200 meters), the Municipality of Metropolitan Seattle initiated a three year baseline study...
REMOTS?: Reconnaissance of Benthic Environments
REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling...
Using Multi-Attribute Analysis to Establish Marine Pollution Research Priorities
The paper discusses how techniques like multi-attribute analysis, when used in workshops or surveys, can be most effectively applied to enriching the informational basis for future agency...
Chronic Marine Pollution: A Maine Case Study
The State of Maine has adopted the concept of cumulative impact in assessing the environmental impact of coastal development projects and resulting discharges to coastal waters. In the...
New Tools for Economic Evaluation of Channel Deepening Projects
The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from...
Quantifying Chemicals in Coastal Environments
Because management and regulation is largely based on numerical chemical data, understanding of the process, products and limitations of environmental chemical analysis is critical for...
Caribbean Coastal Marine Productivity (CARICOMP): A Regional Laboratory Network
The CARICOMP (Caribbean Coastal Marine Productivity) project began with a workshop in 1982. Marine scientists from 12 Caribbean nations gathered to consider the factors controlling the...
Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...
Dispersion of Coal Particles at the Sea Floor
Due to coal unloading, certain quantities of this material arrive at the sea floor, and may pollute the beaches. This study provides a theoretical analysis and numerical simulations of...
California's Fourteen Years of Coastal Zone Management
California's Coastal Zone Management Program has been considered the flagship of the nation; yet large questions remain as to whether the program can protect California's...
Albemarle-Pamlico Sounds: Issues, Resources, and Management (
The Albemarle-Pamlico Sound complex, located in northeastern North Carolina, is the third largest estuarine complex in North America and the second largest in area in the United States....
Nearshore Sand Sources for American Samoa: An Alternative to Using Beach Sand
Using a combination of geophysical techniques, in situ observations, and sampling by scuba divers, we investigated along the south shore of Tutuila Island, American Samoa, for nearshore...
Northwest Regional Coastal Study: An Integrated Approach
The Northwest Regional Coastal Study as proposed consists of: (1) identification of problems; (2) inventory of available information; (3) prioritizing problems and study areas; (4) conducting...
Movement of Nonaqueous Liquids in Groundwater
Evidence from field sites indicates that when nonaqueous liquids, such as organic solvents and gasoline, are released into the subsurface environment they tend to remain as a separate...
Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...
Plastic Concrete Cutoff Walls
The studies revealed that plastic concrete can be prepared having a coefficient of hydraulic conductivity that is less than 1 multiplied by 10** minus **7 cm/sec. The shear strength of...
Automated Permit Review for Hazardous Waste Surface Impoundments
The United States Environmental Protection Agency has proposed to develop automated permit review for RCRA hazardous waste surface impoundment facilities. The review automation will consist...
Thickened Slurry Disposal Method for Process Tailings
Common practice in the disposal of process tailings consists of impounding the wastes as thin slurries or suspensions in diked containment areas. Such a procedure poses problems relating...
