Used Rebreather Scrubber Disposal

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.

Rewilding Coral Reefs 

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 Research Grants

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.

Close-Focus Wide-Angle Photography

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.

Linden Wolbert

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.
