For the work on my novel, I’ve been researching breathable gas mixtures for saturation diving.

• Saturation diving
• Argox
• Hydrox
• Hydreliox
• Trimix
• Theoretical considerations on the ultimate depth that could be reached by saturation human divers; Abraini, Risso et al.
• Probing the Limits of Human Deep Diving; Bennett, Elliott et al.
