Readers join an Alvin pilot and scientists in an exciting journey as they voyage down deep to the ocean floor to collect samples and conduct research. Named for Allyn Vine, who helped pioneer deep submergence research and technology for the Woods Hole Oceanographic Institute, Alvin helped in the exploration of the Titanic wreckage in 1986. "Imagine you're the pilot of Alvin, a deep-sea submersible barely big enough for three," the engaging text begins. Cusolito's inviting, "you are there" narration puts readers inside the submersible to discover what one wears, eats, and talks about during a typical eight-hour journey to learn about life inhabiting the deepest realms of our oceans. How do you breathe? What kind of music might you listen to? How do you see when you "enter thick blackness"? The answers to those and many other questions are answered. The voyage down is not without perils: "Fishing nets or anchor chains could entangle Alvin and trap you." On the seafloor, "Eerie spires loom. Black smokers blast scalding water and poisonous, sooty particles from deep inside Earth.

" The digitally created illustrations evoke the dark mysteriousness of the deep ocean and depict the crew as a man of color, a white woman, and a white man. Endmatter explains how Alvin works and describes the author's and illustrator's research. An appealing, exhilarating, and informative vicarious journey of discovery. -- Kirkus Reviews, STARRED REVIEW.
