Large amounts of pollutants and natural disasters have been released into coastal and marine waters, wreaking havoc on the ecosystem and ecology. Pollution and habitat loss caused by humans have had and continue to have a significant impact on worldwide coastal and estuarine ecosystems. More than 80% of all marine pollution originates on land, with the majority of it coming from industrial, agricultural, and urban sources. Coastal and marine pollution is caused by human activities such as offshore oil and gas extraction and maritime oil transportation. Many of the world's estuaries and coastal zones are experiencing eutrophication, hypoxia, and other negative consequences as a result of anthropogenic activities. As a result, it's vital to avoid and regulate coastal and marine pollution, as well as build improved monitoring protocols and systems to aid in the understanding of spatial and temporal changes in coastal water quality. Recent technological advancements in coastal and marine seawater quality monitoring, such as real-time data collecting via data buoys, large-scale remote sensing intervention, automated data collection, and so on, are critical for comprehending real-time data and its influence on the environment.

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

This book describes critical environmental issues that face coastal ocean and Great Lakes areas, including eutrophication, habitat modification, hydrologic and hydrodynamic disruption, exploitation of resources, toxic effects on ecosystems and humans, introduction of nonindigenous species, global climate change and variability, and shoreline erosion and hazardous storms. These issues can be approached through science activities (including research, monitoring, and modeling) discussed in this book and through coordination among federal agencies.

"In its resolutions 57/141 and 58/240, the General Assembly decided to establish a regular process under the United Nations for global reporting and assessment of the state of the marine environment, including socioeconomic aspects, both current and foreseeable, building on existing regional assessments. In its resolution 71/257, the Assembly recalled that the scope of the first cycle of the Regular Process focused on establishing a baseline and decided that the scope of the second cycle would extend to evaluating trends and identifying gaps. The programme of work for the period 2017-2020 of the second cycle of the Regular Process includes the preparation by the Group of Experts of the Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects, of the second World Ocean Assessment, building on the baselines established by the First Global Integrated Marine Assessment (first World Ocean Assessment). In its resolution 72/73, the Assembly decided that the Group of Experts should proceed on the basis of a single comprehensive assessment. The present document was prepared by the Group of Experts in accordance with those decisions"--Summary.

This is the first report of the Circumpolar Biodiversity Monitoring Program (CBMP) to summarize status and trends in biotic elements in the arctic marine environment. The effort has identified knowledge gaps in circumpolar biodiversity monitoring. CBMP is the cornerstone program of Conservation of Arctic Flora and Fauna (CAFF).

The World Ocean Assessment - or, to give its full title, The First Global Integrated Marine Assessment - is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.

World Seas: An Environmental Evaluation, Second Edition, Volume Two: The Indian Ocean to the Pacific provides a comprehensive review of the environmental condition of the seas from the Indian Ocean to the Pacific. Each chapter is written by experts in the field who provide historical overviews in environmental terms, current environmental status, major problems arising from human use, informed comments on major trends, problems and successes, and recommendations for the future. The book is an invaluable worldwide reference source for students and researchers who are concerned with marine environmental science, fisheries, oceanography and engineering and coastal zone development. - Covers regional issues that help countries find solutions to environmental decline that may have already developed elsewhere - Provides scientific reviews of regional issues, thus empowering managers and policymakers to make progress in under-resourced countries and regions - Includes comprehensive maps and updated statistics in each region covered

This volume deals with problems related to monitoring, analysis and modelling of coastal regions, including sea, land and air phenomena. Bringing together papers presented at the Sixth International Conference on Environmental Problems in Coastal Regions, the book focuses on ecological and environmental problems and the issues of water quality. The book will be essential to researchers, engineers and professionals involved in the field of Coastal Environmental quality and the related challenges to monitoring and controlling Oil Spills. Topics of interest include: Remote Sensing; Ecology and the Coastal Environment; Water Quality Issues; Wetlands; Sediment Problems; Coastal Restoration; Atmospheric Aspects; Sea States Forecasting; Modelling of Trajectory and Fate of Spills; Bioremediation; Detection, Prevention and Clean-up Measures; Erosion Problems; Management of Risk; Preservation of Pristine Coastal Areas; Estuarial Problems; Floods; Climate Change and the Coastal Environment.
