Invasion of the Zebra Mussels
At first glance, the zebra mussel looked like doom for freshwater users in the Great Lakes: small, hardy, incredibly prolific European mollusks with an affection for freshwater intakes...
Promoting Management Systems Within Organizations
The major effort during the years in which pavement management emerged as an accepted practice was making refinements to the technical models and techniques in the systems. For example,...
Highway Maintenance and Integrated Management Systems
Maintenance management systems were among the first applications of rational management principles and the (then) the new technology of computers to highway operations. Recent changes...
An Integrated Design/Construction Research Program for Infrastructure Rehabilitation
The quality of America's infrastructure today is barely adequate to fulfill current requirements, and sufficient to meet the demands of future economic growth and development. This serious...
An Application of MCDM to Product-Based Pavement Management
The Finish National Roads Administration is currently developing it's organization to be more object-oriented and profit-making. This renewal implies to so called product-approach. In...
Establishing a HSGT System Organization
Most of the attention on High Speed Ground Transportation systems thus far has been devoted to their technological, financial and construction aspects, and this was understandable since...
Status of Contamination in the Coastal United States as Revealed from NS&T Analyses of Surface Sediments
Sediment samples have been collected from more than 300 sites along the coasts of the U.S. since 1984 as part of NOAA's National Status and Trends (NS&T) Program. These samples...
Temporal Trends of Chemical Contamination at NS&T Sites
Recent temporal trends in concentrations of ten trace elements (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) and of five groups of organic compounds (butyltins, tDDT, tCdande, tPCB, and...
The NS&T Intensive Bioeffects Surveys: Design Strategies and Preliminary Results
Intensive bioeffects surveys are conducted in selected areas where chemical data from the National Status and Trends (NS&T) Program indicate greatest potential for contaminant-related...
Production and Decomposition of
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...
Results from Minerals Management Service Funded Oil Spill Response Research 1991-1993
Large oil spills from tankers have reaffirmed the need for continuing technology assessment and research to improve oil spill response capabilities. This paper discusses Minerals Management...
Recovery of Shoreline Ecosystems Following the
High-pressure, hot-water washing was evaluated as one of several countermeasures for cleaning oiled shorelines. This was the primary treatment method for nearly all treated shorelines...
Effects of Estuarine Habitat Quality on Juvenile Salmon: I. Chemical Contaminant Exposure and II. Altered Growth and Immune Function
Some urban estuaries on the west coast of the US are important habitats for several species of juvenile salmon and receive multiple stresses from human activities. Because these estuaries...
Sandy Beach Restoration in Heavily Populated Areas
Urban coastal areas are marked by several conflicts between its use and the conservation of its use and the conservation of its natural features. The Rio de Janeiro State University -...
Traffic and Lead Pollution on Lake Maracaibo's Western Coast
This project focused on Nerium Oleander (NO) (Berberia), an ornamental plant. Chemical analyses (acid digestion and atomic absorption spectrophotometry) of the plant's tissue and the soil...
NOAA, Bioassessment Techniques and the Superfund Process
The National Oceanic and Atmospheric Administration's (NOAA) assessments of SUperfund sites require an evaluation of whether contaminants are present in an aquatic environment of concern,...
Contaminant Trends in the Southern California Bight: The Coast is Cleaner
Data from local, regional and federal coastal monitoring programs were used to assess long-term trends and spatial extent of chemical contamination in sediments, shellfish, and fish of...
Pre-Spill Planning for Natural Resource Damage Assessments
The effectiveness of the natural resource damage assessment (NRDA) process for oil and chemical spills can be improved by planning and coordination among natural resource trustees before...
An Ongoing Field Study to Evaluate the Impacts and Direct Effects of Offshore Dreding Activities on Benthic Organisms
Instrumentation and sampling involve box coring, otter trawling, the use of a towed sled carrying video camera, and a sidescan sonar device. The baseline collection phase of the study...
Studies of Contaminants in Arctic Marine Mammals
Attention has been directed over the last few years to determining the baseline levels of anthropogenic contaminants in Arctic marine mammals. Because of their subsistence value to local...
