This nonfiction picture book tells the story of two men obsessed with the sea. Otis Barton, an engineer, and Will Beebe, a naturalist, both wondered what the deep ocean looked like. In the 1930s they worked together to build a diving tank called the Bathysphere that would allow explorers to go deeper than ever before. The dramatic text and mixed-media illustrations chronicle their record-setting dive in increments of 100 feet. A wordless double gatefold captures the blue-black beauty of the ocean at the depth of 800 feet. Roy’s lush illustrations portray the time period, the technical details, and action of the underwater world. Sea life is featured on the endpapers with labels. Readers will not be disappointed in the accuracy and depth of content. The ample back matter includes archival photographs as part of the author’s and illustrator’s notes105Please respect copyright.PENANAJBjz6VWHe0
