DIVE DEEPER

Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and...
Close to the volcanic CO 2 seeps, the vast diversity of corals that exists in less-acidic waters is replaced by a "monoculture" of boulder corals. These are less fragile and better suited to life in...
Far away from the volcanic CO 2 seeps, a healthy coral reef flourishes with a diversity of coral species. Closer to the seeps where the water is acidic, the corals barely even grow. Read more about...
Scientists predict that ocean acidification will impact communities around the world. One of them is the Suquamish Nation , an American Indian tribe on the Puget Sound, in the Pacific Northwest...
Much of the carbon dioxide we emit into the atmosphere ends up in the ocean. As CO 2 levels rise, seawater becomes more acidic. This change in chemistry poses a serious threat to marine organisms...
Corals are not only found in shallow tropical waters, but in cold, dark, deep areas of the sea. Amazing coral forests are found at depths of 60-3,050 meters (200-10,00 feet). They support an...
GEOMAR scientist Armin Form works at his lab during a long-term experiment on the effects of lower pH, higher temperatures and "food stress" on the cold-water coral Lophelia pertusa . In a previous...
Closest to the seeps, where the pH is lowest and the water is most acidic, corals no longer grow. Instead there are sand, rubble and seagrasses that are able to survive. Read more about how reef...
Coral reefs are beautiful, vibrant ecosystems that house roughly one quarter of all marine species and provide billions of dollars in products and services to humans each year. But they are also...
How do we know ocean carbon dioxide levels are rising and pH is decreasing? By taking measurements of seawater over many years. This graph shows rising levels of carbon dioxide (CO 2 ) in the...
