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...

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...
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...
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...
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...
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...
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...
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...
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...
Bill Taylor, Paul Taylor, Diani Taylor and Brittany Taylor have more in common than just a last name; they also share a business. The Taylors have been in the family oyster-farming business 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...
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...
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...
Nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that could provide the key to our understanding of one of the biggest threats to coral reef survival: Ocean Acidification...

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...
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...
