To clarify for non-divers, the 62ft depth where this is located isn't considerably deep. Recreational divers regularly reach that. For comparison, the Navy's original SEALAB[1] habitats from the 60's were deployed at around 200ft and today's commercial saturation divers can work at depths of up to ~1000ft [2]. The fact they're staying there for long periods is significant, as well of course is the type of research and training they're doing. Saturation diving is common in the oil and gas industry. Sometimes they bring workers up in a sealed, submersible hyperbaric chamber and keep them at pressure in between dives to avoid wasting time decompressing after each work shift. Accidents can be gruesome[3], and accordingly the pay is considered good (e.g. US$1400/day). Here are other submerged habitats you can read about; there are even underwater hotels, restaurants etc. at shallower depths that you can visit: https://en.wikipedia.org/wiki/Underwater_habitat#Historical_underwater_habitats https://en.wikipedia.org/wiki/Underwater_habitat#Historical_... --- [1] https://en.wikipedia.org/wiki/SEALAB https://en.wikipedia.org/wiki/SEALAB [2] https://en.wikipedia.org/wiki/Saturation_diving#Depth_records https://en.wikipedia.org/wiki/Saturation_diving#Depth_record...
