Dive into the world of Alvin the Submersible, as award winning journalist Aly Brown shares the stories of what lies beneath the waves, including lost hydrogen bombs, underwater volcanoes, storied shipwrecks, and hundreds of new species. Humans have explored the far reaches of the globe, from the top of Mount Everest to Badwater Basin--a stretch of land 282 feet below sea level. But for most of our time on this planet, the ocean has been a huge mystery. It's only in the last 50 years that scientists have really started studying the ocean floor, with the help of one amazing creation: Alvin the submersible. A deep-sea vessel that can sink miles below the surface with three people inside, Alvin and its crew have uncovered a treasure trove of information in the last 50 years. From tracking down lost hydrogen bombs to exploring underwater volcanoes known as black smokers to capturing footage of the Titanic's watery grave, there's so much waiting to be discovered beneath the waves! Join award winning journalist Aly Brown as she dives into the wonders of Alvin's world and see for yourself what lies in the last unexplored place on earth!.
