Sorb, or scrubber, plays a critical role in rebreather diving, as it is responsible for removing carbon dioxide (CO2) from the diver’s breathing gas. Small granules or pellets absorb exhaled CO2 and allow oxygen to pass through. This chemical process allows rebreathers to recycle exhaled air, limiting gas consumption and allowing longer dives.
DAN’S NEW OFFICIAL PODCAST, The DANcast, delivers safety insights through engaging conversations from across the dive industry. This series blends practical knowledge with personal stories to inform and inspire the dive community.
Though I believe rewilding coral reefs is a valuable approach, it requires a strong, established foundation of good old-fashioned marine conservation. I view reef rewilding as a tertiary marine conservation strategy that we should attempt only after the fundamentals of an effective marine conservation strategy (often anchored with a well-managed marine protected area) are in place.
DAN has introduced the Research Grant Program, designed to push the boundaries of dive safety through innovative research. The program will support studies that develop robust theories and empirical evidence that contribute to safer dive experiences.
Most of our experiences in digital photography are somewhere between one end of a spectrum and the other. Underwater photographers often make an either/or distinction when describing how we shoot, ignoring that it is really a continuum.
Any child predisposed to a love of nature will likely find their way to natural environments, which happened early and fortuitously for Linden Wolbert. When she turned 1 year old, her family moved to an old farm in Pennsylvania, not far from where George Washington crossed the Delaware River during the Revolutionary War.
Van Morrison dropped his 34th album, Born to Sing: No Plan B, in 2012. David Fleetham, now 48 years into his career as a professional underwater photographer, reflects on that sentiment when explaining how underwater photography has subsumed his life.
The high seas have long represented a frontier of wild adventure — a place where people took significant risks and untold fortunes were waiting to be snatched from the jaws of a capricious ocean.
I am a 57-year-old male who is planning to undergo a laparoscopic Nissen fundoplication for refractory gastroesophageal reflux disease (GERD) and a hiatal hernia. Is the procedure considered an absolute […]
Reef Environmental Education Foundation (REEF) has a long history of connecting the dive community to marine conservation. Through the Volunteer Fish Survey Project (VFSP), REEF has empowered divers to contribute valuable data for more than 30 years, transforming recreational dives into opportunities for scientific research and ecosystem protection.
