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 structure of their shells, their metabolism, or their behavior. Or researchers can go to areas...

Far away from the volcanic CO2 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 even grow. Read more about how reef scientist Laetitia Plaisance uses carbon dioxide seeps to study...

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 vulnerable to human activities – both direct disturbances and small, indirect effects that build up over...

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. Here cool carbon dioxide naturally bubbles out of volcanic cracks in the shallow sea floor and...

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 Life, Ari Daniel Shapiro and researcher Dr. Randi Rotjan of the New England Aquarium, journey to the...
