Oceanauts
Oceanaut (n.) An oceanaut is a person who lives and works underwater for scientific research purposes. 1 Oceanaut had to survive in an underwater condition, which is considerably different than living on ground. There were a few snags when oceanauts first started diving. Conshelf project, led by Jacques Cousteau, was an underwater project where oceanauts lived underwater to conduct research on marine life and human behavior in an underwater environment. 2 The oceanauts involved in this was one of the earliest of their kind, so they were constantly being monitored for health anomalies. Due to lack of air down in the water, they had to get accustomed to breathing in air manipulated specifically for oceanauts. At first it was changing the oxygen to nitrogen ratio for a higher nitrogen ratio, then having helium mixed with oxygen instead of nitrogen. 3 This was done to prevent them from getting sick. Even though air is fine on ground, in underwater where everything is under pressure, breathing in air was too dense for them. These discoveries showed of human life in underwater will be difficult while also showing how there is a possibility of it, once more technology improves and there is proper research conducted.
