aquanauts
Deep-sea habitat residents
Aquanauts are people who work or live underwater for extended periods, typically in underwater habitats or research stations.
The term parallels astronaut, substituting water for the cosmos.
Aquanauts conduct marine research, test diving equipment, or explore ocean environments that require prolonged submersion beyond what standard diving allows.
The aquanauts spent two weeks living in the undersea laboratory studying coral reef ecosystems.
