Book Description
Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

Book Description
U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.

Book Description
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.

Book Description
At an increasingly global scale, aquatic scientists are heavily entrenched in understanding the fate of marine ecosystems in the face of human-altered environments. Oil spill disasters, especially large-scale ones like the 2010 Deepwater Horizon tragedy, have left uncertain and indelible marks on marine ecosystems. Impacts of Oil Spill Disasters on Marine Habitats and Fisheries in North America contains independent scientific findings and critical reviews from experts researching the impacts of the Exxon Valdez, Ixtoc I, and Deepwater Horizon oil spills on coastal fishery resources. Comprised of three sections, this seminal work: Details the physiological effects of oil-derived compounds on fishes, presenting results from field and laboratory investigations Addresses the science of assessing the impacts of oil spills and oil response measures on coastal habitats, with an emphasis on salt-marsh ecosystems in the Gulf of Mexico Explores the quantified and potential impacts of oil spills on population and community dynamics of commercial and recreational fishery species Provides newly released results from the 25-year recovery of marine mammals, birds, and fishes following the Exxon Valdez spill Chapters discuss new techniques for collecting and processing blood samples for toxicity testing, new aerial radar techniques for detecting unseen oil on marshes, consequences of oil prevention measures (such as diverting fresh water to estuaries or building sand berms to stop oil) on coastal fishery resources, and non-traditional methods for assessing the herring stock in Prince William Sound, Alaska, USA following the Exxon Valdez disaster.

Book Description
Countering violent extremism consists of various prevention and intervention approaches to increase the resilience of communities and individuals to radicalization toward violent extremism, to provide nonviolent avenues for expressing grievances, and to educate communities about the threat of recruitment and radicalization to violence. To explore the application of health approaches in community-level strategies to countering violent extremism and radicalization, the National Academies of Sciences, Engineering, and Medicine held a public workshop in September 2016. Participants explored the evolving threat of violent extremism and radicalization within communities across America, traditional versus health-centered approaches to countering violent extremism and radicalization, and opportunities for cross-sector and interdisciplinary collaboration and learning among domestic and international stakeholders and organizations. This publication summarizes the presentations and discussions from the workshop.

Book Description
Marine oil spills are no longer considered unavoidable "accidents" resulting from adverse environmental conditions or functions of catastrophic events. More than 80% of all spills are the result of "human error". The focus of the current legal, regulatory, and convention framework affecting the transportation of oil by ship reflects a recent change in public attitude, in which there is an insistence upon protection of the world¿s marine environments, particularly coastal ecosystems. The outcome of such global attention is the creation of significant legal and political motivators for a cultural shift by the oil shipping industry, from an "evasion culture" to a "safety culture". The new safety culture connotes continuous improvement in ship operations and a willingness to adopt the evolving concepts of communication at all levels, better trained and qualified personnel on board ship, emphasis of safety from top down, and proactive institution of safety management systems. Mere compliance with international and national laws is no longer sufficient for future sustainable shipping. These changes and advancements in understanding the science and engineering of oil spills are the focus of this book on Oil Spills First Principles. They are Prevention, based upon adoption of the safety culture, and Best Response, utilizing scientific, technical and environmental data and information. Over the past 30 years, billions of US dollars have been spent in R&D planning, response and clean up of oil spills. All of these efforts have focused on achieving Best Response. The concept of time periods of "Technology Windows-of-Opportunity" for a given response and clean up technology has developed from the leadership and wisdom of researchers and responders from many nations using modeling of the weathering of spilled oil and technology effectiveness. The Windows-of-Opportunity strategy provides a scientific basis for policy and decision-making in oil spill planning, response, and training. A global paradigm shift is needed to more effectively utilize and expedite the application of lessons learned in both prevention and clean up. Recognition of economic, political, and legal benefits accruing from environmental protection is good for business and critical for sustainable shipping.
