Download or read book Ecological Quality Status of Marine Environment written by Gehan Mohamed El Zokm and published by Springer Nature. This book was released on 2023 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this one-of-a-kind book was to provide a critical and in-depth understanding of various AVS-SEM models as predictors for assessing the ecological impact of heavy metals (particularly dibasic cations; Zn, Cd, Ni, Cu, and Pb) on aquatic environments, including the theories underlying these models, descriptive equations, modes of action, methodology, efficiency, applicability, and statistical approaches, as well as comparison with other pollution assessment techniques in the aquatic environments. Metals in interstitial water can be reduced in sediments that co-precipitate with iron (Fe) and manganese (Mn) in FeS or MnS minerals, as well as replace them. This book outlines a system that can be used to track heavy metal contamination in countries with coastal regions that extend over water bodies that are subjected to pollution sources, such as the Mediterranean Basin countries. Moreover, this book will be of great interest to academics, professionals, practitioners, post-graduate students (M.Sc. and Ph.D.), and undergraduates because it gives a clear overview of heavy metal assessment for people interested in environmental studies focusing on the marine environment. It also provides decision-makers with a realistic perspective of the environmental file, allowing them to address environmental issues and directing stockholders to safer locations for environmental activity. From a future perspective, management is advised to overcome the difficulties within that technique, such as accurate handling procedures and different approaches to sampling onshore and offshore. Sequential leaching strategies, especially geochemical fractionation analysis, and knowledge of the interactions and significance of AVS in the marine sector, especially toxicity tests (bioassay) are recommended.

Download or read book Ocean Acidification written by National Research Council and published by National Academies Press. This book was released on 2010-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Download or read book Marine Environmental Quality written by Frederic Muttin and published by John Wiley & Sons. This book was released on 2021-10-26 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding marine pollution and the contamination of coastal environments requires knowledge from a variety of scientific fields. Marine Environmental Quality promotes a multidisciplinary approach to investigations, drawing on not only natural sciences, but also applied mathematics and social sciences. The investigations in this book focus on both organic and inorganic pollutants, firstly in a study conducted in the city of La Rochelle, on the North Atlantic French coast, then expanding the areas under examination to regions of English and Portuguese waters and, lastly, to the Mediterranean Sea. The improvement such research can bring to biomarkers, models and experiments enables equal progress in the quality of seawater in ports and protected areas of coastal regions. The eight chapters of Marine Environmental Quality present many aspects of this research, including experiments with floating barriers, water governance in various areas, sampling sites and sentinel species that act as biomarkers in harbors. Also covered are environmental commitments, both international and local, the risk that marine contamination poses to human health, experimental designs for interactions with microplastics and a study biomonitoring the juveniles of sentinel species. Such results will bring many benefits, to human health, to economic inclusion and to regional development.

Download or read book Coastal Marine Ecosystems of Latin America written by U. Seeliger and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

Book excerpt: Marine Ecosystem Services (MARECOS) is an interdisciplinary study that provides relevant information for national, Nordic and international ecosystem services assessments and valuation in the implementation of marine policy. This report aims to provide suggestions on how ecosystem condition assessments, being based on the Marine Strategy Framework Directive (MSFD), and the HELCOM indicator based assessments for the Baltic Sea, could be used for the assessment of ecosystem services. By describing the potentials of linking data and knowledge describing the status of marine ecosystems and water quality to the values of the services and goods provided, the report offers useful information for policy and decision makers in the domain of the marine and aquatic policies around the Baltic and in the Nordic countries.
Download or read book Oceanography and Marine Environment in the Basque Country written by A. Borja and published by Elsevier. This book was released on 2004-03-03 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Against a background of extensive multi-disciplinary oceanographic investigations over a number of years, together with the long-term establishment of a Society and Institute, extensive information is available from studies undertaken in the estuarine and coastal waters of the Basque Country.The present authors gained access to unpublished literature and reports which, together with a synthesis of internationally-refereed papers, provide a series of scientific overviews of particular subject areas. Teams of researchers (from Basque Institutes and Universities) combine to present the present 'state of knowledge', within a global context, of processes ranging from sub-seabed to air-sea interaction - incorporating data on the associated biology (including fisheries) and pollutant sources and levels. The latter are compared with regional, national and European legislation. The volume is divided into various sections: Introduction; Geography and Oceanography; Chemical Oceanography and Water Quality; Sediment Characteristics, Quality and Chemistry; Biomonitoring; Communities and Ecology; and Overall Assessment.The topics covered include: an historical review of marine research; the impact of human activities, during past centuries; geology, geomorphology and sediments; climate and meteorology; marine dynamics; hydrography; water mass characteristics; contaminants in the waters; microbiological quality; sedimentological characteristics; contaminants in sediments; biomonitoring of heavy metals and organic components, at tissue organism level and using cellular and molecular biomarkers; bacterioplankton and phytoplankton communities; zooplankton communities; benthic communities; seabirds; biodiversity and conservation; recovery of benthic communities; the polluted systems; and assessment of human impacts. On the basis of these syntheses, future challenges for marine research in the Basque Country are identified, in terms of a 'Research Agenda'. This comprehensive text, relating to estuarine, coastal and oceanographic processes at wide-ranging spatial and temporal scales in the southern Bay of Biscay, will be of interest to researchers, engineers and legislators - on a regional basis and within a world-wide perspective.
Download or read book State of the World s Oceans written by Michelle Allsopp and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world’s oceans cover 70% of the earth’s surface and are home to a myriad of amazing and beautiful creatures. However, the biodiversity of the oceans is incre- ingly coming under serious threat from many human activities including overfi- ing, use of destructive fishing methods, pollution and commercial aquaculture. In addition, climate change is already having an impact on some marine ecosystems. This book discusses some of the major threats facing marine ecosystems by cons- ering a range of topics, under chapters discussing biodiversity (Chapter 1), fisheries (Chapter 2), aquaculture (Chapter 3), pollution (Chapter 4) and the impacts of increasing greenhouse gas emissions (Chapter 5). It goes on to explore solutions to the problems by discussing equitable and sustainable management of the oceans (Chapter 6) and protecting marine ecosystems using marine reserves (Chapter 7). Presently, 76% of the oceans are fully or over-exploited with respect to fishing, and many species have been severely depleted. It is abundantly clear that, in general, current fisheries management regimes are to blame for much of the widespread degradation of the oceans. Many policy-makers and scientists now agree that we must adopt a radical new approach to managing the seas – one that is precautionary in nature and has protection of the whole marine ecosystem as its primary objective. This ‘ecosystem-based approach’ is vital if we are to ensure the health of our oceans for future generations.
