Flying Deep: Climb inside Deep-Sea Submersible ALVIN

This nonfiction account follows a day aboard Alvin, a deep-sea submersible. The vessel descends about two miles to the ocean floor, where its pilot works with scientists. At the seafloor, the scientists gather samples and carry out research. The book also notes Alvin’s role in locating the Titanic, framing the trip as an exploration of the deep ocean and the work conducted there.
