Which of the following is an example of an overhead environment?

• A. Ice
• B. Open water
• C. Coral reef
• D. Breakwater

Answer: (A)

Overhead environments are dives where you can’t reach the surface directly above you. Under ice fits this because you’re under a solid ice ceiling and must exit through a hole or opening to surface. The surface isn’t immediately over you, so you need special planning, lines or reels, and surface support. Open water, coral reef, and a breakwater are not overhead in the same way; you can usually surface directly from where you are, or there’s a clear path to the surface nearby.
