NOAA's Ocean Acidification Program prepares us for the impacts of ocean acidification through research and interdisciplinary partnerships.

Ocean acidification has already crossed a crucial threshold for planetary health, scientists say in unexpected finding * More on this story: The scientists warning the world about ocean acidification – ‘evil twin’ of the climate crisis The world’s oceans are in worse health than realised, scientists have said today, as they warn that a key measurement shows we are “running out of time” to protect marine ecosystems. Ocean acidification, often called the “evil twin” of the climate crisis, is caused when carbon dioxide is rapidly absorbed by the ocean, where it reacts with water molecules leading to a fall in the pH level of the seawater. It damages coral reefs and other ocean habitats and, in extreme cases, can dissolve the shells of marine creatures. Continue reading...

Alaska's Emerald Isle and the Changing Seas Around It

The global climate system is complex. In order to unpack such complexity, the WMO State of the Global Climate uses seven Climate Indicators to describe the changing climate. The following site aims to...

Sweeping research cuts in President Donald Trump's proposed budget would target an ocean-monitoring system that scientists say is crucial to predicting tsunami escape routes and hurricane intensity an...

Abstract. The Bering Sea shelf supports a highly productive marine ecosystem that is vulnerable to ocean acidification (OA) due to the cold, carbon-rich waters. Previous observational evidence suggest...
