This book was released on 2013-03-14 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the coastal human population increases in the United States, there will likely be increasing environmental and socioeconomic pressures on our coastal and estuarine environments. Monitoring the condition of all our nation's coastal and estuarine ecosystems over the long term is more than any one program can accomplish on its own. Therefore, it is crucial that monitoring programs at all levels (local, state, and federal) cooperate in the collection, sharing, and use of environmental data. This volume is the proceedings of the Coastal Monitoring Through Partnerships symposium that was held in Pensacola, Florida in April of 2001, and was organized by the U.S. Environmental Protection Agency's (EPA's) Environmental Monitoring and Assessment Program (EMAP), and the Council of State Governments (CSG). It contains papers that describe various multi-disciplinary coastal and estuarine environmental monitoring programs, designed and implemented by using regional and national partnerships with federal and state agencies, academia, Native American tribes, and nongovernmental organizations. In addition, it includes papers on modeling and data management; monitoring and assessment of benthic communities; development of biological indicators and interlaboratory sediment comparisons; microbiological modeling and indicators; and monitoring and assessment of phytoplankton and submerged aquatic vegetation. There are many components involved in determining the overall impacts of anthropogenic stressors on coastal and estuarine waters. It will take strong partnerships like those described in this volume to ensure that we have healthy and sustainable coastal and estuarine environments, now and in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Current ecological risk assessment methodologies have limited capacity to account for the spatial heterogeneity in Stressors and physical/chemical conditions characteristic of aquatic and estuarine ecosystems. The Shannon-Weaver index was utilized to construct spatial models of benthic macroinvertebrate biodiversity in Chesapeake Bay over several time periods between 1987-2001. These models were subsequently compared to monitoring data for sediment contaminant concentrations and physical/chemical water quality conditions. A series of GIS exercises demonstrated that low values for species diversity were associated with higher concentrations of a diverse array of contaminants as well as physical/chemical water quality conditions. Multivariate regression analysis among a range of contaminant and water quality variables accounted for up to 61% of the observed variation in benthic biodiversity. Collectively, these results demonstrate the numerous challenges for conducting ecologically relevant risk assessments at the ecosystem level, which can be partially ameliorated with quality monitoring data and geographic approaches to environmental assessment.

Download or read book Achieving Nutrient and Sediment Reduction Goals in the Chesapeake Bay written by Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction to Improve Water Quality and published by . This book was released on 2011-09-26 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.

Book excerpt: This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

Dauer and published by . This book was released on 2002 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Benthic macrofauna are an important component of estuarine ecosystems. These organisms are a food source for higher trophic levels including fishes and crabs and birds. Benthic macrofauna affect both the physical and chemical properties of the sediment and the overlying water column, influence nutrient cycling, and are capable of directly controlling phytoplankton biomass in the water column. Because of these characteristics, monitoring of the benthos provides important information for making management decisions in marine systems. Also, the relatively long life span and sedentary nature of these organisms make them good indicators of water quality and the effects of man-made disturbances on aquatic systems. The objective of this study was to develop analytical tools that are capable of classifying regions in Chesapeake Bay identified as having degraded benthic communities into categories distinguished by the type of stress experienced by those communities.
