[IOOS Ocean Acidification Program homepage]  The NOAA Ocean Acidification Program focuses on monitoring the changes in the ocean chemistry, researching potential effects on organisms and ecosystems, and understanding the socio-economic impacts of those changes.

Knowledge from this research will allow to explore adaptations strategies and to better communicate the progress and implications of ocean acidification with scientists, stakeholders, and the public.

Since the start of the industrial revolution, the ocean has silently absorbed roughly 30% of the carbon dioxide that people generate through industry and agriculture.  Now ocean chemistry of the seawater is rapidly changing in a process known as ocean acidification. These changes in seawater chemistry affect animal growth, survival and behavior, and they are depleting the ocean of calcium carbonate, a nutrient vital for shellfish to build shells. Marine organisms with calcium carbonate shells or skeletons – such as corals, oysters, clams, and mussels – can be affected by small changes in acidity. That’s important, because shelled organisms are essential throughout the marine food chain. They are also vital to our economy, as shellfish hatcheries on the brink of collapse just a few years ago, struggle to adapt.

The U.S. Integrated Ocean Observing System, or IOOS, is helping mitigate economic impacts with real-time data that signal the approach of acidified seawater one to two days before it arrives.  An early warning helps hatchery managers take action – such as shutting off intake valves or treating the water – to save crops…
