"A biographical account of engineer Otis Barton and naturalist Will Beebe's record-setting descent into the deep ocean in their Bathysphere craft, making the men the first humans to witness deep sea creatures in their natural habitat"-- The little-known true story of the first deep dive into the ocean. One June 6, 1930, engineer Otis Barton and explorer Will Beebe dove into the ocean inside a hollow metal ball called the Bathysphere. They knew dozens of things might go wrong. A tiny leak could shoot pressurized water straight through the men like bullets! A single spark could cause their oxygen tanks to explode! No one had ever dived lower than a few hundred feet...and come back. But Otis and Will were determined to become the first people to see what the deep ocean looks like. This suspenseful story from acclaimed author Barb Rosenstock with mesmerizing watercolors by award-winning artist Katherine Roy will put you right in the middle of the spine-tingling, record-setting journey. -- From dust jacket.
