This dataset is a movie about hydrothermal vents at volcanoes in the deep sea, formatted specifically for NOAA's Science On a Sphere. Viewers experience virtual dives to underwater volcanoes spewing hot water and learn that life can thrive near these extreme environments. We visit vents at a hotspot volcano, at a volcano on a convergent boundary, and at a volcano on a divergent boundary - the mid-ocean ridge. The movie highlights the Pacific Ring of Fire, interweaving global datasets with imagery of the seafloor obtained from deep-diving vehicles.
