Great Carrier Reef

A decommissioned aircraft carrier, the USS Oriskany, is stripped down and sunk off the coast of Florida, transforming from a retired warship into the world's largest artificial reef.

For the kid who lines up toy ships and asks how things actually get built and taken apart, this book follows a real vessel through its second life underwater.

• Big idea: Something built for one purpose can be transformed to serve another — endings can become beginnings.
• Vibes: Fascinating, hopeful, and grounded in real engineering and marine science.

• are curious about ships, machines, and how big things are built
• love ocean animals and underwater ecosystems
• enjoy real-world STEM stories with detailed illustrations
• are starting to think about caring for the environment

• Real-life connection: Have you ever seen a reef, an aquarium, or pictures of the ocean floor? What lived there?
• Story & problem-solving: Why do you think the team of scientists and engineers had to prepare the Mighty O so carefully before sinking it?
• Imagination: If you designed an artificial reef, what shape or materials would you use?
• Big ideas: Why do you think turning an old ship into a reef helps ocean animals?
• Feelings & empathy: How do you think it felt for the people who once worked on the Mighty O to see it become a reef?
