The Last Unexplored Place on Earth: Investigating the Ocean Floor with Alvin the Submersible

Aly Brown takes readers on a real-world adventure aboard Alvin, the famous deep-sea submersible. The book blends vivid narrative with photographs and diagrams to show how scientists explore pitch-black depths, discover hydrothermal vents teeming with life, and recover historic artifacts such as pieces of the RMS Titanic. By tracing Alvin’s major missions from the 1960s to today, the author explains oceanography, marine biology, geology, and the technology that makes extreme exploration possible. Children come away with a sense of wonder about Earth’s last frontier and a call to protect fragile ocean ecosystems.
