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.
With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process (known as ocean acidification) whereby seawater becomes less alkaline as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. Scientists are concerned that increasing hydrogen ion concentration could reduce growth or even cause the death of shell-forming animals (eg: corals, molluscs, and certain planktonic organisms) as well as disrupt marine food webs and the reproductive physiology of certain species. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Scientists are concerned that increasing hydrogen ion concentration in seawater could alter biogeochemical cycles, disrupt physiological processes of marine organisms, and damage marine ecosystems. This book examines potential legislative action by Congress relating to authorising, funding, and co-ordinating research to increase knowledge about ocean acidification and its potential effects on marine ecosystems.
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 identifi...
This important Research Handbook provides a guide to navigating the tangled array of laws and policies available to counter the ominous threats of ocean acidification. It investigates the limitations and opportunities for addressing ocean acidification under national, regional and global governance frameworks, including multilateral environmental agreements, law of the sea and human rights instruments.

This book critically examines the available literature on oceanic acidification, including a historical review of pH and atmospheric CO2 levels over the millennia; natural and anthropogenic sources of CO2 to the atmosphere and sea surface; chemical, physical, and biological mode of action; biological effects of acidification to marine plants and an
The world's ocean has already experienced a 30% rise in acidity since the industrial revolution, with acidity expected to rise 100 to 150% over preindustrial levels by the end of this century. Potential consequences to marine life and also to economic activities that depend on a healthy marine ecosystem are difficult to assess and predict, but potentially devastating. To address this knowledge gap, Congress passed the Federal Ocean Acidification Research and Monitoring (FOARAM) Act in 2009, which, among other things, required that an interagency working group create a "Strategic Plan for Federal Research and Monitoring of Ocean Acidification." Review of the Federal Ocean Acidification Resear...
Ocean Acidification and Marine Wildlife: Physiological and Behavioral Impacts provides comprehensive knowledge on how decreases in the pH of the world's oceans is affecting marine organisms. The book synthesizes recent findings about the impacts of ocean acidification (OA) on marine animals, covering the physiological and behavioral effects upon marine invertebrates and vertebrates, the potential physiological and molecular mechanism affects, and interactions of OA with other environmental factors. Written by international experts in this research field, this book summarizes new discoveries of OA effects on fertilization, embryonic development, biomineralization, metabolism, immune response,...
Ocean acidification is the process whereby seawater becomes less alkaline (or more acidic). It is a concern to Congress because of the potential harm ocean acidification may cause to marine resources, and resource dependent industries and communities. The chemistry of the Earth's oceans is changing as increasing amounts of anthropogenic carbon dioxide from the atmosphere dissolves into the water. The intent of this book is to guide research and monitoring investments that will improve our understanding of ocean acidification and its potential impacts on marine species and ecosystems. It will further the development of adaptation and mitigation strategies to conserve marine organisms and the resources and services provided by the ecosystems in which they live.
