Book Description

This book discusses temporal changes in six Asia-Pacific marginal seas and two west boundary currents in the Northwest Pacific. Covering time scales varying from years to decades, it provides a comprehensive review of the long-term changes in various physical variables, including sea level, sea surface temperature, water mass index, current and transport, as well as local issues such as sea ice and tidal mixing, and the processes and dynamics that govern them. The book also examines biogeochemical variables, such as nutrients, oxygen, pH, water transparency, ocean acidification, eutrophication and productivity, and explores future trends. Offering a holistic view of the changes that have occurred in the Asia-Pacific marginal seas and those that are likely to occur in the future, this book will appeal to readers from all fields of oceanography.

Book Description

Coral reefs, which are one of the most productive and biodiverse ecosystems on Earth, serve various important roles, such as providing shelter and spawning grounds to a wide range of marine animals. However, the global decline of hard corals in tropical and subtropical regions is a growing concern. A recent review of the Intergovernmental Panel on Climate Change (IPCC) indicated that only 10%–30% of coral reefs would survive with an increase of 1.5 °C in global warming temperature. Of coral reefs around the world, the coral reefs in eastern Asia face one of the most industrially developed and high population areas in the world. Thus, coral reefs of eastern Asia have been affected by various anthropogenic factors, such as eutrophication, coastal development, anthropogenic pollutants, ocean acidification, disease, and overfishing. Therefore, urgent research is required to determine the levels at which different factors will affect coral health. Besides, we propose a perspective on coral reef (especially those in eastern Asia) conservation under climate change and various anthropogenic activities.

The image is modified based on Figure 1a of Lucey et al. (this Research Topic) and Figure 7b of Niemi et al. (this Research Topic). (A) Graphical depiction of atmospheric warming and increasing atmospheric carbon dioxide (CO2atm), which drives ocean warming, contribute to the decreases in dissolved oxygen (DO), and lowers pH and saturation state index of calcium carbonate (Ω). The partial pressure of CO2 (pCO2) increases due to increasing atmospheric CO2 that is absorbed into the seawater (i.e., ocean acidification), along with other biological processes in the marine environment.

Book Description

Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.

Book Description

Nearly two-thirds of the world's population live in Asia, and many countries in that region are currently undergoing very rapid industrial, agricultural and economic development. The Framework Convention on Climate Change constrains developed countries with regard to their future emissions of greenhouse gases, but recognizes the special needs of developing countries. There is growing appreciation of the ways in which developing countries in the Asian region both contribute to global changes (by altering biogeochemical pathways and cycles) and are themselves affected by those changes. This volume uses the intellectual efforts and findings of the International Geosphere-Biosphere Programme (IGBP) community to provide the first integrated analysis of the interactions between global change and Asian change, giving particular attention to China's role. The book will be of interest to readers in a wide range of academic disciplines (natural sciences and socio-economic) and for those involved in national and international policy development relevant to global change.

Book Description

The Indo-Pacific is fast becoming the world's dominant region. As it grows in power and wealth, geopolitical competition has reemerged, threatening future stability not merely in Asia but around the globe. China is aggressive and uncooperative, and increasingly expects the world to bend to its wishes. The focus on Sino-US competition for global power has obscured "Asia's other great game": the rivalry between Japan and China. A modernizing India risks missing out on the energies and talents of millions of its women, potentially hampering the broader role it can play in the world. And in North Korea, the most frightening question raised by Kim Jong-un's pursuit of the ultimate weapon is also the simplest: can he control his nukes? In Asia's New Geopolitics: Essays on Reshaping the Indo-Pacific, Michael R. Auslin examines these and other key issues transforming the Indo-Pacific and the broader world. He also explores the history of American strategy in Asia from the 18th century through today. Taken together, Auslin's essays convey the richness and diversity of the region: with more than three billion people, the Indo-Pacific contains over half of the global population, including the world's two most populous nations: India and China. In a riveting final chapter, Auslin imagines a war between America and China in a bid for regional hegemony and what this conflict might look like.

Book Description

This encyclopedia adopts a wider definition for the concept of ocean engineering. Specifically, it includes (1) offshore engineering: fixed and floating offshore oil and gas platforms; pipelines and risers; cables and moorings; buoy technology; foundation engineering; ocean mining; marine and offshore renewable energy; aquaculture engineering; and subsea engineering; (2) naval architecture: ship and special marine vehicle design; intact and damaged stability; technology for energy efficiency and green shipping; ship production technology; decommissioning and recycling; (3) polar and Arctic Engineering: ice mechanics; ice-structure interaction; polar operations; polar design; environmental protection; (4) underwater technologies: AUV/ROV design; AUV/ROV hydrodynamics; maneuvering and control; and underwater-specific communicating and sensing systems for AUV/ROVs. It summarizes the A–Z of the background and application knowledge of ocean engineering for use by ocean scientists and ocean engineers as well as nonspecialists such as engineers and scientists from all disciplines, economists, students, and politicians. Ocean engineering theories, ocean devices and equipment, ocean design and operation technologies are described by international experts, many from industry and each entry offers an introduction and references for further study, making current technology and operating practices available for future generations to learn from. The book also furthers our understanding of the current state of the art, leading to new and more efficient technologies with breakthroughs from new theory and materials. As the land resources approach the exploitation limit, ocean resources are becoming the next choice for the sustainable development. As such, ocean engineering is vital in the 21st century.
