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...

Far away from the volcanic CO 2 seeps, the water is unaffected and a healthy coral reef flourishes with a diversity of coral species. Closer to the seeps where the water is acidic, the corals barely...

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...

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...

Branching corals, because of their more fragile structure, struggle to live in acidified waters that surround the volcanic CO 2 seeps of Papua New Guinea. Read more about how reef scientist Laetitia...

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...

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...

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 that are less fragile and better suited to life in...

Fossil fuels that power our cars, homes, and businesses add carbon dioxide (CO2) to the atmosphere. The ocean absorbs large portions of this CO2 and acts as a buffer against climate change . But, Dr...

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...
