My stay in Jules’ Undersea Lodge started in March 2023. The habitat, secured to the bed of a 30ft-deep lagoon in Key Largo, Florida, wasn’t the most comfortable hotel I’ve spent time in, but then I wasn’t there for a holiday. I’m a biomedical researcher and I was there as part of a scientific mission called Project Neptune 100.
The main aim was to research the mental and physical impact on the human body of living in increased atmospheric pressure – 70% higher than at the surface. It was also to study what happens when you leave someone alone in a confined environment for 100 days. The data might have all manner of applications – for future missions to Mars, for example.
