(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.

Following the first international workshop on the economics of ocean acidification organized by the Centre Scientifique de Monaco and the International Atomic Energy Agency in 2010, a second international workshop was held in November 2012, which explored the level of risk, and the resilience or vulnerability of defined regions of the world ocean in terms of fishery and aquaculture species and economic impacts, and social adaptation. This report includes the findings and recommendations of the respective regional working groups and is the result of an interdisciplinary survey of ocean acidification-sensitive fisheries and aquaculture.

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.

Thomas Jefferson envisioned a nation of citizens deeply involved in public life. Today Americans are lamenting the erosion of his ideal. What happened in the intervening centuries? Daniel Kemmis argues that our loss of capacity for public life (which impedes our ability to resolve crucial issues) parallels our loss of a sense of place. A renewed sense of inhabitation, he maintains —of community rooted in place and of people dwelling in that place in a practiced way—can shape politics into a more cooperative and more humanly satisfying enterprise, producing better people, better communities, and better places. The author emphasizes the importance of place by analyzing problems and possibilities of public life in a particular place— those northern states whose settlement marked the end of the old frontier. National efforts to “keep citizens apart” by encouraging them to develop open country and rely upon impersonal, procedural methods for public problems have bred stalemate, frustration, and alienation. As alternatives he suggests how western patterns of inhabitation might engender a more cooperative, face-to-face practice of public life. Community and the Politics of Place also examines our ambivalence about the relationship between cities and rural areas and about the role of corporations in public life. The book offers new insight into the relationship between politics and economics and addresses the question of whether the nation-state is an appropriate entity for the practice of either discipline. The author draws upon the growing literature of civic republicanism for both a language and a vantage point from which to address problems in American public life, but he criticizes that literature for its failure to consider place. Though its focus on a single region lends concreteness to its discussions, Community and the Politics of Place promotes a better understanding of the quality of public life today in all regions of the United States.

Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.

Managing Ocean Environments in a Changing Climate summarizes the current state of several threats to the global oceans. What distinguishes this book most from previous works is that this book begins with a holistic, global-scale focus for the first several chapters and then provides an example of how this approach can be applied on a regional scale, for the Pacific region. Previous works usually have compiled local studies, which are essentially impossible to properly integrate to the global scale. The editors have engaged leading scientists in a number of areas, such as fisheries and marine ecosystems, ocean chemistry, marine biogeochemical cycling, oceans and climate change, and economics, to examine the threats to the oceans both individually and collectively, provide gross estimates of the economic and societal impacts of these threats, and deliver high-level recommendations. - Nominated for a Katerva Award in 2012 in the Economy category - State of the science reviews by known marine experts provide a concise, readable presentation written at a level for managers and students - Links environmental and economic aspects of ocean threats and provides an economic analysis of action versus inaction - Provides recommendations for stakeholders to help stimulate the development of policies that would help move toward sustainable use of marine resources and services

The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases in pH and carbonate ions and an increase in bicarbonate ions. The consequences of this overall process, known as "ocean acidification", are raising concerns for the biological, ecological, and biogeochemical health of the world's oceans, as well as for the potential societal implications. This research level text is the first to synthesize the very latest understanding of the consequences of ocean acidification, with the intention of informing both future research agendas and marine management policy. A prestigious list of authors has been assembled, among them the coordinators of major national and international projects on ocean acidification.
