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,...
Coordinating Fishery Management and Habitat Conservation
The 1986 and 1990 amendments to the Magnuson Fishery Conservation and Management Act strengthened the role of regional fishery management councils (councils) and NMFS when commenting on...
Potential Benefits of Harvest Refugia in Channel Islands National Park and Channel Islands National Marine Sanctuary
Waters surrounding the California Channel Islands are managed for many diverse, and apparently conflicting, uses. Generally, activities are permitted that do not threaten long-term resource...
Evolution (1980-1990) of Ammonia and Dissolved Oxygen in Guanabara Bay, RJ, Brazil
The UFRJ is located on an island of Guanabara Bay and the Institute of Biology has been developing systematic studies on the bay. A synthesis of these studies and their different methodologies...
Pre-Operational Considerations for Marine Finfish Aquaculture: Site Selection and Allocation in British Columbia
Marine fish farming is a new component in the complex mixture of coastal resource uses in British Columbia. To ensure that the marine finfish aquaculture industry develops within an environmentally...
An Analysis of Modeling Techniques in Pollution Management of Natural Water Systems
This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study...
Water, an Endangered Ecosystem; the Assessment of Chemical Pollution
The pervasive nature of water and its accessibility to mankind leaves it open to a variety of man-induced changes ranging from diversion of water flows to heavy metals pollution. The abuses...
The Use of IFIM for Evaluating Effects of a Flow Alternative on Fish Habitat in a River System with Competing Water Demands
The Instream Flow Incremental Methodology (IFIM) was used to evaluate instream fish habitat in the Platte River in central Nebraska. The IFIM analysis presented herein incorporates 1)...
Evaluation of Alternatives for Providing Minimum Flows Below TVA's South Holston Dam
TVA is in the initial phases of a project to provide minimum flows in the South Fork Holston River below South Holston Dam. The purposes of the minimum flows at South Holston are to enhance...
A Water Budget Approach to Instream Flow Maintenance
Storage reallocation is a current issue at many Federal water storage facilities that have hydroelectric generation. Allocation of storage to support instream flows is one of the changes...
Instream Flow Needs Below Peaking Hydroelectric Projects
A method has been developed to assist in the determination of instream flow needs below hydroelectric projects operated in a peaking mode. Peaking hydroelectric projects significantly...
Mercury in Fish and Water in New Impoundments?A Review of the Literature
Evidence to date indicates that only one metal, mercury, systematically bioaccumulates to ecologically significant concentrations as a direct result of impoundment. This bioaccumulation...
Harrisburg Hydroelectric Project?Water Quality Issues
The Harrisburg Hydroelectric Project is a proposed 34.4 MW hydroelectric facility on the Susquehanna River near Harrisburg, Pennsylvania. The project will consist of a 16.5 ft high gated...
Thermal Regimes at Tailwaters of Hydroelectric Dam
Continuous temperature data were collected in the field for periods of approximately two weeks in Center Hill Tailwater. These data were analyzed to determine the warming rates and travel...
