The National Estuarine Eutrophication Assessment (NEEA) is a tool for evaluating both current eutrophic condition and the effectiveness of management actions aimed at reducing eutrophic condition. Eutrophication is caused by excess nutrients and is expressed by symptoms such as increased ...

Submerged aquatic vegetation (SAV) provides many important ecosystem functions, but SAV has been significantly reduced in many estuaries. We used spatial–statistical models to identify estuarine shoreline characteristics that explain variations in SAV abundance among subestuaries of the Chesapeake Bay and ...

Coastlines worldwide are being altered due to shoreline hardening and stabilization and while highly altered systems are subject to change, variability exists in how shoreline hardening affects benthic communities depending on the landscape features of the system and regional production ...

Salt marsh ecosystems are sensitive habitats that may be susceptible to oil and oil spill mitigation chemicals during clean up. This research project assessed the toxicity of three shoreline cleaners (SLC) in laboratory and mesocosm exposures, determined petroleum hydrocarbon distributions ...

Egg deposition by the intertidal spawning fish Atlantic silverside (Menidia menidia) was compared among six shoreline types (Spartina alterniflora, Phragmites australis, sandy beach, riprap, riprap-sill, and bulkhead) and various substrates. In spring 2010, M. menidia egg density was measured daily ...

Oceanographic features, such as eddies and fronts, enhance and concentrate productivity, generating high-quality patches that dispersive marine larvae may encounter in the plankton. Although broad-scale movement of larvae associated with these features can be captured in biophysical models, direct evidence ...

Stable isotope analysis has become a common tool for mapping trophic relationships, describing foodweb changes, and assessing ecosystem health. Clear interpretation of stable isotopes is facilitated by understanding how environmental factors can affect isotopic values; in estuarine systems, these factors ...

This document is the first annual statistical summary for the Carolinian Province estuaries component of the nationwide Environmental Monitoring and Assessment Program (EMAP). EMAPEstuaries in the Carolinian Province is jointly sponsored by the National Oceanic and Atmospheric Administration (NOAA) and ...

A study was conducted to assess the environmental condition of estuaries in the EMAP Carolinian Province (Cape Henry, VA St. Lucie Inlet, FL). A total of 87 randomly located stations was sampled from July 5 September 14, 1995 in accordance ...

This report presents data generated from samples of water, sediment, and biota collected in the Neuse River, NC during the summer of 1998. The sampling effort is part of a joint study, initiated by the National Oceanic and Atmospheric Administration ...
