Maug’s Caldera: A Natural Laboratory – Full Episode

In the remote Pacific, the islands of Maug rise out of the sea. Here shallow hydrothermal vents are found close to coral reefs. These vents emit levels of CO2 that can be expected in the world’s oceans by the end of the century, making these waters a natural laboratory for scientists studying the impacts of ocean acidification on coral reefs.
