Download or read book Hypoxia in the Northern Gulf of Mexico written by Virginia H. Dale and published by Springer Science & Business Media. This book was released on 2010-04-12 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot s- port marine life, generally manifests itself in the spring. Since marine species either die or ee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational shing in the Gulf. Since 2001, the hypoxic zone has averaged 2 1 16,500 km during its peak summer months , an area slightly larger than the state 2 2 of Connecticut, and ranged from a low of 8,500 km to a high of 22,000 km . To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together represen- tives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Of ce of Science and Technology Policy to conduct a scienti c assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR).

Book excerpt: Since 1985, scientists have been documenting a hypoxic zone, an area of low dissolved oxygen that cannot support marine life, in the Gulf of Mexico each year. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force was formed to bring together representatives from federal agencies, states and tribes to consider options for responding to hypoxia. This book summarises major findings and recommendations with regard to hypoxia in the Northern Gulf of Mexico.

Book Synopsis Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico by : Committee on Clean Water Act Implementation Across the Mississippi River Basin
Download or read book Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico written by Committee on Clean Water Act Implementation Across the Mississippi River Basin and published by National Academies Press. This book was released on 2012-12-31 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most water resources managers, scientists, and other experts would agree that nonpoint source pollution is a more pressing and challenging national water quality problem today than point source pollution. Nonpoint sources of pollutants include parking lots, farm fields, forests, or any source not from a discrete conveyance such as a pipe or canal. Of particular concern across the Mississippi River basin (MRB) are high levels of nutrient loadings--nitrogen and phosphorus--from both nonpoint and point sources that ultimately are discharged into the northern Gulf of Mexico (NGOM). Nutrients emanate from both point and nonpoint sources across the river basin, but the large majority of nutrient yields across the MRB are nonpoint in nature and are associated with agricultural activities, especially applications of nitrogen-based fertilizers and runoff from concentrated animal feeding operations. Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico offers strategic advice and priorities for addressing MRB and NGOM water quality management and improvements. Although there is considerable uncertainty as to whether national water quality goals can be fully realized without some fundamental changes to the CWA, there is general agreement that significant progress can be made under existing statutory authority and budgetary processes. This book includes four sections identifying priority areas and offering recommendations to EPA and others regarding priority actions for Clean Water Act implementation across the Mississippi River basin. These sections are: USDA's Mississippi River Basin Healthy Watersheds Initiative; Numeric Water Quality Criteria for the northern Gulf of Mexico; A Basinwide Strategy for Nutrient Management and Water Quality; and, Stronger Leadership and Collaboration.
Book Synopsis Eutrophication in Coastal Ecosystems by : Jesper H. Andersen
Download or read book Eutrophication in Coastal Ecosystems written by Jesper H. Andersen and published by Springer. This book was released on 2012-03-14 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses on monitoring and modelling of coastal eutrophication, and adaptive and science-based nutrient management strategies. The book is based on selected papers from the Second International Symposium on Research and Management of Eutrophication in Coastal Ecosystems, held 20-23 June 2006 in Nyborg, Denmark.

Book Synopsis An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico by : National Research Council
Download or read book An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico written by National Research Council and published by National Academies Press. This book was released on 2013-12-20 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the Gulf of Mexico recovers from the Deepwater Horizon oil spill, natural resource managers face the challenge of understanding the impacts of the spill and setting priorities for restoration work. The full value of losses resulting from the spill cannot be captured, however, without consideration of changes in ecosystem services-the benefits delivered to society through natural processes. An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico discusses the benefits and challenges associated with using an ecosystem services approach to damage assessment, describing potential impacts of response technologies, exploring the role of resilience, and offering suggestions for areas of future research. This report illustrates how this approach might be applied to coastal wetlands, fisheries, marine mammals, and the deep sea-each of which provide key ecosystem services in the Gulf-and identifies substantial differences among these case studies. The report also discusses the suite of technologies used in the spill response, including burning, skimming, and chemical dispersants, and their possible long-term impacts on ecosystem services.
Book Synopsis Nutrients and Eutrophication in Estuaries and Coastal Waters by : Emma Orive
Download or read book Nutrients and Eutrophication in Estuaries and Coastal Waters written by Emma Orive and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature. The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities. Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water. Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.
Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
