Full carbonate chemistry at the site of calcification in a tropical coral

Coral reefs are made up of massive calcium carbonate skeletons. A new study, published in Science Advances on January 16th 2019, reveals insights into the calcification process that leads to the formation of these skeletons. Elucidating coral calcification is key to a deeper understanding and better predictions of how and why coral reefs respond to environmental changes such as ocean acidification.
