Deep-Ocean Exploration Technology

深海探索技术

Description

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

Assessment Prompt

Can your child 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?
