Ocean Acidification and Shellfish
Ocean Acidification and Shellfish explores the escalating threat of increasingly acidic ocean waters on shellfish populations and marine ecosystems. With rising carbon emissions, the book examines how altered ocean pH levels directly impact shell formation, growth rates, and overall survival of various shellfish species. This decline has far-reaching consequences, affecting marine food webs, coastal communities, and aquaculture industries that rely on these creatures. Focusing on the chemical processes and the biological impacts on shellfish at different life stages, the book uniquely investigates depth-related variations in acidification effects, often overlooked in other studies. It progresses from introducing the fundamentals of ocean acidification and historical trends to analyzing physiological mechanisms affecting shellfish, dedicating chapters to specific species like oysters and clams. Mitigation strategies, including reducing carbon emissions and developing resilient shellfish strains, are also discussed. Drawing from diverse scientific literature and incorporating case studies, the book emphasizes the urgent need to address ocean acidification to protect marine biodiversity and ensure the sustainability of shellfish harvesting. This comprehensive analysis makes it a valuable resource for marine biologists, policymakers, and anyone concerned with environmental science and the future of our oceans.

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.
Guide to Best Practices for Ocean Acidification Research and Data Reporting
The ocean presently takes up one-fourth of the carbon dioxide emitted to the atmosphere by human activities, thereby increasing ocean acidity. While our understanding of the possible consequences of ocean acidification is still rudimentary, both the scientific community and the society at large are increasingly concerned about the potential risks associated with ocean acidification for marine organisms and ecosystems. The number of scientists involved in ocean acidification research grew rapidly over the past few years and will continue to rise with the launch of new coordinated national programmes. Students, young researchers, and established scientists inexperienced with the intricacies of the seawater carbonate chemistry and perturbation experiments will enter the field and will benefit from guidelines and standards for ocean acidification research. The European Project on OCean Acidification (EPOCA) and the Intergovernmental Oceanographic Commission (IOC) initiated the process that led, after an open community review, to the production of this guide.
