Book Synopsis Effects of Trawling and Dredging on Seafloor Habitat by : National Research Council
Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Book Synopsis Caractérisation et traitement de sédiments de dragage contenant des polluants métalliques by : Franck Marot

This book was released on 1998 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette étude est d'évaluer les possibilités de décontamination des vases de dragage polluées par des métaux lourds et de déterminer leur devenir après traitement. Les travaux portent sur des sédiments d'estuaires et de canaux prélèves sur différents sites français. Dans un premier temps, les caractérisations physiques, chimiques et minérales de ces produits ont montré des pollutions complexes et parfois très marquées. Les études de spéciation menées par une succession de séparations physiques, d'observations binoculaires et d'analyses au microscope électronique a balayage et a la microsonde, ont permis de déterminer pour chaque sédiment, les principaux porteurs de métaux (microsulfures, précipitations de carbonates, adsorptions sur des grains d'oxyde de fer, particules anthropiques,...). A l'issue de ces travaux, des essais de traitement physique et physico-chimique visant à concentrer ces porteurs sur une fraction pondérale réduite, ont été effectués. La flottation a conduit aux résultats les plus prometteurs. L'efficacité de cette technique de tri est cependant très sensible à la nature des collecteurs chimiques utilises et seuls des tests d'optimisation sont en mesure de parfaire leur choix. Par ailleurs, selon les objectifs de décontamination fixés, des séparations gravimétriques ou densimétriques complémentaires peuvent permettre d'affiner le traitement. Dans un troisième temps, le devenir des matériaux traités a été étudié sur le plan du comportement mécanique. Avec des fractions fines souvent importantes, la consolidation de ces produits est très lente. Pour prédire son évolution dans le temps, une étude expérimentale a été menée en centrifugeuse sous macrogravité. Les degrés de consolidation atteints en fin d'essai (90% après un temps équivalent de 900 jours) et les tassements mesures (70% de la hauteur initiale) ont montré la lenteur et l'importance du phénomène étudié.

Download or read book Contaminated Sediments: written by Marianne Olsen and published by Nordic Council of Ministers. This book was released on 2019-07-09 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nordic Council of Ministers have recognized the need to compile the knowledge of sediment remediation strategies and to evaluate different remediation approaches. The objective of this report is to give a status of regulatory framework and sediment management within selected Nordic countries (Norway, Sweden, Finland and Denmark). In addition, the report gives a short overview of international knowledge on remediation approaches, techniques, and materials. Governance and regulatory instruments in dealing with contaminated sediments vary between countries. Of the countries presented, only Norwegian environmental authorities have implemented a national strategy for remediation of marine contaminated sediments. A Nordic database of clean-up projects and long-term monitoring would improve the exchange of knowledge between the Nordic countries.

Book Synopsis Sediment Risk Management and Communication by : Damià Barceló
Download or read book Sediment Risk Management and Communication written by Damià Barceló and published by Elsevier. This book was released on 2007-03-12 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: In dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase.
