Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and...
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...
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...
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...
Coral reefs are bustling cities of marine life, until rising ocean temperatures turn them into ghost towns. Can reefs spring back from devastating bleaching events? In this episode of the Podcast of...
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...
It’s not an easy question to answer. In the lab, scientists can set up a series of seawater tanks with a variety of pH levels to figure out how different species react to more acidic water, observing...

The acidic waters from CO 2 seeps can dissolve shells and also make it harder for shells to grow in the first place. Read more about how reef scientist Laetitia Plaisance uses carbon dioxide seeps to...
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...
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...

For three weeks, the research ship MV Chertan is home-base for the scientific team and will be transformed in a floating laboratory to study volcanic CO 2 seeps. Read more about how reef scientist...
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...
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...

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...
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,...
