Nitrification in a Salt Wedge Estuary
Autotrophic nitrifying bacterial activity and numbers were measured in a salt wedge estuary receiving ammonium-rich effluent from a municipal secondary wastewater treatment facility. Instream...
Current Research Efforts in Determining the Effects of Tributyltin Use in Marine Paints in the Chesapeake Bay Estuary
In the mid-seventies, manufacturers of marine paint began to use a tin-based biocide called tributyltin or TBT. TBT has been found to be very effective in slowing the biofouling process....
A Regional Screening Method for Classifying Pollutant Status of Coastal Waters
A regional assessment method has been developed to classify estuaries on the basis of their pollution severity, enabling resource managers to prioritize clean-up and future research efforts....
A New Approach to Watershed Planning
Public and government concern over possible degradation of water quality and natural resources in the Hood Canal estuary has led to the creation of a unique intergovernment body, the Hood...
Long Island Sound: Issues, Resources, Status, and Management
The Long Island Sound estuary is an unusual and complex estuary which probably serves more people than any other estuary in the United States. In spite of the enormous and varied stresses...
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....
Louisiana Estuaries: Issues, Resources, Status and Management
Louisiana has more extensive estuarine environments than any other state. These estuaries are comparatively young, having been formed in part by the building and destruction of lobes of...
Restoration of Atlantic Salmon to Maine: Overcoming Physical and Biological Problems in the Estuary
By the early part of the Twentieth Century, all native runs of anadromous Atlantic salmon (Salmo Salar) were extirpated from rivers of the United States, with the exception of a few small...
A Prospective Study of the Oyster-Farming in Senegal, West Africa
Various coastal lagoons and estuaries of the region have become oversaline as a consequence of the persistant drought across Sahel. We have monitored the possible consequences of hight...
Special Canada-U.S. Workshop/Panel
Panel members with hands-on-experience in estuarine planning and management are drawn from British Columbia, Washington, Oregon and California. They highlight those factors which they...
Waste Disposal Activities and the Protection of Estuaries and Coastal Waters
The disposal of wastes in the Nation's marine environments raises two fundamental issues: first, the general health of the several types of marine waters - estuaries, coastal...
Restoring of Butcher's Slough Estuary?A Case History
A 30-acre parcel of former lumber and plywood mills occupying original estuary and salt marsh wetlands on the northern edge of Humboldt Bay, Humboldt County, north coastal California,...
Modeling Dilution of Wastewater Outfalls in a Tidal Estuary
Field studies and modeling have been conducted to assess initial dilution of wastewater outfalls in Puget Sound, a fjord-like estuary in the State of Washington. Recent numerical dilution...
Jean Lafitte's Real Legacy and Treasure
The Barataria Estuarine System is part of the Mississippi River which swept back and forth across Louisiana for thousands of years. Barataria Bay no longer receives the enrichment of the...
Remote Sensing of Estuaries and Tide-Dominated Coastal Processes
The recent appearance of low-cost microcomputers with user-friendly software for analyzing satellite imagery is including more estuarine investigators to use satellite data. High resolution...
Remote Sensing of Estuarine Dynamics Using the NOAA Polar-Orbiting Weather Satellites
The Advanced Very High Resolution Radiometer (AVHRR) onboard the NOAA-n series polar-orbiting weather satellites collects data that can be used to estimate surface water temperature and...
Satellites Monitor Eutrophication of Estuaries
In a study on eutrophication of estuaries, NOAA/AVHRR satellite data have been analyzed for the Changjiang River plume and the adjacent coastal areas. The different regimes identified...
Salinity Intrusion Predictions by Analytical Expressions
Salinity intrusion in estuaries has traditionally been predicted by use of physical models and more recently by numerical models. Analytic techniques have seen quite limited use because...
Time Variability of Suspended Material Concentrations in Estuaries
The concentration of suspended materials (SMC) within estuarine systems varies in response to a variety of factors. This variability complicates sampling SMC and establishes particular...
On the Definition of Fluid Mud
Fluid mud is a near-bed, high density cohesive sediment suspension layer which is a common cause of estuarial and nearshore sedimentation. It is noted that for a given sediment-fluid mixture,...
