Maug's Caldera: A Natural Laboratory A Co-Production with Open Boat Films
changing seas

This episode takes viewers into an area of the remote Pacific, the islands of Maug. Formed by an ancient volcano, shallow hydrothermal vents are found close to coral reefs inside the submerged caldera. 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.

Duration: 26 minutes and 46 seconds

Episode Number: 803
