Ep 19. Volcanoes of the Deep

The NOVA season 26 episode 19, "Volcanoes of the Deep," explores some of the world's most mysterious and spectacular undersea volcanoes.

The underwater geology of the Pacific Ocean is home to an incredible array of nearly 200 undersea volcanoes, often referred to as seamounts. The episode delves into these seamounts, revealing the unique and fascinating worlds that lie beneath the water's surface. Viewers will learn about the cutting-edge technology scientists are using to explore and study these undersea volcanoes.

The episode features interviews with leading scientists in the field of underwater volcanology, who explain just how significant these undersea volcanoes are for our understanding of the planet's geological processes. Viewers will learn how these volcanoes contribute to the Earth's tectonic shifts and generate new oceanic crust, affecting marine life in the surrounding areas.

The episode also details the dramatic expeditions that have taken place to explore these undersea volcanoes. Scientists have deployed remotely operated submersibles to get a close-up view of the volcanoes and collect samples of the marine life that call these environments home. The footage captured by these submersibles is truly breathtaking, showcasing the otherworldly beauty of the seamounts.

The episode doesn't shy away from the risks involved in exploring these extreme environments. Scientific expeditions to undersea volcanoes are often fraught with danger, from equipment malfunctions to toxic gases released by the seamounts. The show captures the tension and excitement of these expeditions, as scientists push the boundaries of what we know about the planet's undersea world.

Overall, "Volcanoes of the Deep" is a fascinating exploration of the mysteries of the undersea volcanoes that dot the Pacific Ocean. The episode is a visual feast, featuring stunning footage of these seamounts and the marine life that surrounds them. It's also a compelling look into the scientific process of studying these extreme environments, showcasing the incredible dedication and ingenuity of the researchers who venture beneath the ocean's surface.
