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...
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,...
Boring sponges get a bad rap. Their own name betrays them, announcing to the world that they are unexciting, ordinary and quite frankly, boring. However, if ever a misnomer existed, this is it. 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...

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...
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...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
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...
