Download or read book Oil in the Sea III written by National Research Council and published by National Academies Press. This book was released on 2003-03-14 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
Download or read book Conservation of Marine Resources and Sustainable Coastal Community Development in Malaysia written by Muhammad Mehedi Masud and published by Springer. This book was released on 2019-07-26 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses a timely and compelling emerging issue related to the conservation and sustainable use of marine resources and the sustainable development of the coastal community. Marine protected areas (MPAs) make a remarkable contribution to the protection of marine communities by providing sustainable livelihoods, deriving financial benefits from the development of fisheries and tourism, as well as by restoring ocean productivity and preventing further environmental degradation. These areas have been considered the cornerstone of a blue economy due to their substantial economic, social and environmental contributions. However, MPAs around the world are severely hampered by a multitude of issues and challenges such as inefficient management, poor socioeconomic conditions and environmental degradation due to human activities, overexploitation of marine resources, degradation of water quality, massive waste production and climate change. These are the main obstacles to economic, social and environmental sustainability. Hence, a collaborative management approach and an integrated management policy framework is urgently needed for the economic, social, political, cultural, technological, and ecological development of coastal communities.

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.

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 Anthropogenic Litter written by Melanie Bergmann and published by Springer. This book was released on 2015-06-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.
Download or read book The Economics of Fishing written by Rögnvaldur Hannesson and published by Economics of Big Business. This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fishing industry's critical dependence on the natural environment makes it very different from other economic sectors. The industry comprises everything from operator-owned small boats to large corporations operating fleets of high-tech trawlers or purse seiners processing their catches into finished products. All however exploit a common resource. This book provides an introduction to the economics of the fishing industry and the role of fisheries in the world economy. It focuses primarily on capture fisheries, although the discussion brings in wider acquaculture for comparative analysis. Trade in fish products and how it has developed is highlighted, as well as the main rules governing the fish trade. The basic concept of sustainable yield is explained and how economically optimal exploitation is used to avoid overexploitation. The book discusses the variability of fish stocks and uses case studies of some spectacular stock crashes that have occurred. The law of the sea is explained and how the movement of fish stocks across ocean boundaries has meant the development of government and inter-governmental bodies to manage international fisheries. At the heart of this management lies the quota system and the book outlines how it works and how, controversially, such quotas have become transferable and have acquired elements of private ownership. The regulation of the fishing industry is shown to be fundamental to prevent the possible total depletion of fish stocks, yet political pressure from the industry and from pressure groups can make the industry less efficient than it could be. Wider questions about whether fisheries management should only be about food production are also considered. The book offers readers a comprehensive and rigorous guide to the economic considerations motivating the industry and highlights the environmental challenges facing the sector as global consumption of fish continues to rise.

Download or read book Marine Protected Areas written by National Research Council and published by National Academies Press. This book was released on 2001-06-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the ocean-and the resources within-seem limitless, there is clear evidence that human impacts such as overfishing, habitat destruction, and pollution disrupt marine ecosystems and threaten the long-term productivity of the seas. Declining yields in many fisheries and decay of treasured marine habitats, such as coral reefs, has heightened interest in establishing a comprehensive system of marine protected areas (MPAs)-areas designated for special protection to enhance the management of marine resources. Therefore, there is an urgent need to evaluate how MPAs can be employed in the United States and internationally as tools to support specific conservation needs of marine and coastal waters. Marine Protected Areas compares conventional management of marine resources with proposals to augment these management strategies with a system of protected areas. The volume argues that implementation of MPAs should be incremental and adaptive, through the design of areas not only to conserve resources, but also to help us learn how to manage marine species more effectively.
