Near the intense volcanic CO 2 vents bubbling from the cracks in the seafloor, the water is so acidic that it dissolves coral skeletons. Read more about how reef scientist Laetitia Plaisance uses...

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...
Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't...
Branching corals, because of their more fragile structure, struggle to survive in acidified waters that surround the volcanic CO 2 seeps of Papua New Guinea. Read more about how reef scientist...
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...
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...
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...

Stare at a tide pool and you will often see a crust of pink coating the bottom. No, this is not bubblegum from some careless teenager’s shoe: it’s a stony kind of seaweed that, like other seaweeds,...
In Ili Ili Bua Bua, Normanby Island, Papua New Guinea, CO 2 bubbles out of intense volcanic vents in the reef. The excess carbon dioxide dissolves into the surrounding seawater, making water more...
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...
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...
