Understanding the potential consequences of rising ocean carbon levels and related ocean changes for marine life and ecosystems is a high priority for the ocean research community and marine resource management. In the mid-1990s, two geoengineering proposals to mitigate global warming by carbon sequestration in the deep sea led to

The combined effects of acidification and hypoxia on pH and aragonite saturation in the coastal waters of the California current ecosystem and the northern Gulf of Mexico
Highlights In surface waters the percentage change in the carbon parameters due to increasing CO2 emissions are similar. In subsurface waters the changes are enhanced due to changes in the buffer capacity. Increased anthropogenic CO2 concentrations will expose organisms to hypercapnic conditions. Abstract Inorganic carbon chemistry data from the surface and subsurface
Estuaries may experience accelerated impacts of human-caused CO2
Rising anthropogenic, or human-caused, carbon dioxide in the atmosphere may have up to twice the impact on coastal estuaries as it does in the oceans because the human-caused CO2 lowers the ecosystem’s ability to absorb natural fluctuations of the greenhouse gas, a new study suggests. Researchers from the U.S. Environmental Protection
Biologists discover that female purple sea urchins prime their progeny to succeed in the face of stress

Assess, anticipate, adapt: vulnerability and responses to ocean acidification
There are areas in the United States where marine resources and the communities and industries that depend on them are particularly vulnerable to the impacts of ocean acidification. In three US regions, our understanding of vulnerability is being advanced by coupling ocean and social science data to equip communities and
