- 6. Aquanauts are crucial for advancing _ science, mapping deep-sea ecosystems, and ensuring environmental health by living and working underwater at high pressure. (o…)
- 7. Aquanauts stay long enough for their _ to get used to the underwater environment.
- 9. The term “Aquanauts” is often restricted to scientists and academics, though there were a group of _ aquanauts during the SEALAB program. (m…)

- 15. A special house built underwater where aquanauts eat, sleep, and do science experiments.
- 16. SEALAB I, II, and III were experimental underwater habitats developed and deployed by the United States Navy during the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of _.

- 21. An aquanaut is distinct from a submariner, in that a submariner is confined to a moving underwater _ such as a submarine that holds the water pressure out.
- 22. A _ diver carries their own breathing supply, allowing freedom of movement underwater.
- 24. Aquanauts, astronauts, and SCUBA divers all explore extreme, inhospitable _ using specialized equipment to navigate, but differ in depth, duration, and saturation.
- 25. SCUBA stands for a Self-Contained Underwater _ Apparatus.
- 27. An astronaut is a person trained to operate in the vacuum and microgravity of outer _.
- 28. Aquanauts live in underwater habitats for days/weeks in saturated conditions, whereas SCUBA _ typically operate in shorter, non-saturated intervals, and astronauts operate in microgravity/vacuum.
- 30. The first human aquanaut was _ Sténuit, who spent 24 hours on board a tiny one-man cylinder at 200 feet (61 m) in September 1962 off Villefranche-sur-Mer on the French Riviera.

- 3. Aquanauts are saturated, meaning their bodies have absorbed as much nitrogen or other breathing gas as possible. They cannot immediately return to the _ without long, controlled decompression.
- 8. The word is used to describe a person who stays underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as _. (s…)
