Les émissions de dioxyde de carbone (CO2), résultant de la combustion des énergies fossiles par l'activité humaine, renforcent l'effet de serre et provoquent le dérèglement climatique. Alors que la sensibilisation des populations à ce problème planétaire global progresse, l'acidification des océans, qualifiée de « l'autre problème du CO2 », demeure aujourd'hui encore largement méconnue. Cet ouvrage répond aux dix questions clés qui permettent d'aborder les fondements biogéochimiques de l'acidification, les évolutions passées, en cours et à venir, les impacts sur les organismes marins et sur l'homme, et enfin les voies de remédiation. Il puise ses réponses dans des domaines aussi divers que la biogéochimie, l'écologie, la physiologie, l'évolution, l'aquaculture et la pêche, l'économie et la sociologie.

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, foraging, anti-predation, habitat selection, and the social hierarchy of marine animals. This is an important resource for researchers and practitioners in marine conservation, marine wildlife studies, and climate change studies. In addition, it will serve as a valuable text for marine biology and animal science students. - Examines the impacts of carbon dioxide increases in the world's oceans relating to marine vertebrates and invertebrates - Identifies environmental factors, including climate change and pollution and how they increase the negative effects of ocean acidification - Facilitates a better understanding of ocean acidification effects for conservationism and future prevention

This title includes a number of Open Access chapters. This valuable compendium provides an overview of the variables and consequences of oceanic carbon cycling in the context of climate change. The chapters highlight the importance of marine plankton in carbon processing as well as the effects of rising CO2 and temperature in their functioning. Marine ecosystems are being increasingly threatened by growing human pressures, including climate change. Understanding the consequences that climate change may have is crucial to predict the future of our oceans. Rising temperatures and ocean acidification may profoundly alter the mode of matter and energy transformation in marine ecosystems, which could have irreversible consequences for our planet on ecological timescales. For that reason, the scientific community has engaged in the grand challenge of studying the variables and consequences of oceanic carbon cycling in the context of climate change, which has emerged as a relevant field of science. The book is broken into four sections:Understanding the Importance of Ocean BiogeochemistryQuantifying Oceanic Carbon VariablesPhytoplankton and Oceanic Carbon Cycle Ocean AcidificationEdited by a researcher with many years of experience and with contributions from scientists from around the world, this volume explores the most important topics on climate change and oceanic carbon cycling.

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.
