Plural of aquanaut; multiple people trained and equipped to live and conduct research underwater in deep-sea habitats.
Plural of 'aquanaut' (from 'aqua' plus Greek 'nautes'). The term became established after successful underwater habitat experiments in the 1960s demonstrated the feasibility of extended human underwater residence.
Modern aquanauts aren't just explorers—they're scientists studying undersea geology, biology, and even testing technologies for future space missions, since underwater pressure and isolation simulate space conditions in ways that are cheaper and safer to achieve.
