Deep-Ocean Exploration Technology
Explain how crewed submersibles (Alvin, Deepsea Challenger) and remotely operated vehicles (ROVs) allow exploration of the deep; describe acoustic seafloor mapping using sonar and why only ~25% of the ocean floor has been mapped at high resolution; explore why the deep ocean is harder to explore than the surface of the Moon (pressure, cold, darkness, communication difficulties); survey astrobiology missions targeting ocean worlds in our solar system
Suggested ages 13–14

Assessment prompt
Can Deep-Ocean Exploration Technology explain why more of the Moon's surface has been mapped in detail than Earth's ocean floor — what makes deep ocean exploration so much harder than looking at the Moon?
