Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and...
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...
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...
Scientists don’t often get the opportunity to travel through time. But nestled among the beautiful coral reefs of Papua New Guinea (PNG) is a place that provides a glimpse today of what could be 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...
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...
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...
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...
