Maug’s Caldera: A Natural Laboratory

Season 8 Episode 3 | 26m 43s | Video has closed captioning.

In the remote Pacific, the Maug Islands rise out of the sea. Formed by an ancient volcano, shallow hydrothermal vents are found close to corals here. 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 lab for scientists studying the impacts of ocean acidification on coral reefs. A coproduction with Open Boat Films.
