This column is adapted from a chapter in my book, Scuba Physiological – Think you know all about Scuba Medicine? Think Again! The chapters in this book were originally written by scientists in the field of decompression research as part of a three-year project called PHYPODE (Physiology of Decompression). My (self-appointed) task was to rewrite their sometimes-complex research in a form accessible to all divers.

Nestled in the mountainous area of Bestwig in western Germany is the Nuttlar slate mine, which offers divers an intriguing opportunity to step into the past. Kurt Storms gives us a glimpse of the underwater passages in the mine.

Rebreather Forum 4 was held on Malta on 20-22 April 2023 in University of Malta's old campus in downtown Valletta. The event was attended by prominent dive industry entrepreneurs and manufacturers and hyperbaric researchers, many of which presented the latest findings in their fields.

If you have ever wondered how dark the earth was before humans discovered fire, then spend some time in the forest. The night arrives shortly after 6 p.m. and the sun rises around 5 a.m. In this period of time, you may feel enveloped by the darkness in this part of South Africa. Andrea Murdock Alpini shares his adventure diving the Komati Springs.

“Rebreather Friendly” dive centres—what exactly does this mean? With emerging technologies becoming more mainstream in the diving world these days, more and more people are making investments in rebreathers. Everyone knows the advantages of these pieces of kit—extended dive time capabilities, reduced gas usage, quieter and less obtrusive to the aquatic world, etc. But are dive operators thinking along the same lines?

Say you are in some far-flung location where it will take quite some time to get to any recompression chamber. What do you do if you get decompression sickness? Get back in the water and recompress?
