SCUBAnauts

Q4 2023

FOR MORE THAN 20 YEARS the nonprofit marine science education program known as SCUBAnauts International (SNI) has introduced young people ages 12 to 18 to informal science education through underwater exploration. While many youth organizations exist in the dive industry, this group’s scientific rather than recreational nature and its strong foundation in dive safety give SNI a unique identity.

Wolf-Eels

Q4 2023

ASK DIVERS IN THE PACIFIC NORTHWEST what makes for a great dive, and most will agree that a wolf-eel (Anarrhichthys ocellatus) is involved. There is something about the face of an adult wolf-eel staring at you from its den that turns an ordinary dive into a great one. The specific conditions don’t matter. Cold temperatures, terrible visibility, or strong currents are easy to forget when a wolfie — as we call them locally — appears. 

Healing Without Worry

Q4 2023

AFTER I SPENT ALMOST 20 HOURS in a hyperbaric chamber over five days, life there had grown tedious. The last 15 minutes, however, were not only exciting but highly instructive. I learned that if you don’t know what you’re doing, don’t touch anything or do anything without first asking permission.

Commercial Diving Safety

Q4 2023

FOUR SCUBA DIVERS BECAME TRAPPED and died while working in an offshore pipeline in 2022. This incident was a harsh reminder that commercial diving is a “hazardous occupation that presents many dangers that far exceed the risks in sport diving,” as highlighted in The Simple Guide to Commercial Diving. The typical risks in recreational diving, such as decompression sickness and pressure-related injuries to the ears and lungs, are still present, but commercial divers regularly face additional hazards — such as zero visibility, contaminated water, and pressure differentials — all while simultaneously operating industrial tools. 

Freediving Risk Assessments

Q4 2023

THE RAPID GROWTH OF FREEDIVING in the U.S. brings a positive light to a sport that is mentally healthy and physically inspiring but has little tolerance for error. Shallow-water blackout and respiratory barotrauma are the most feared consequences of freediving, but they can be minimized with training and good safety practices. 

Slow and Relaxed with Good Technique

Q4 2023

MY DIVE BUDDY AND I planned to do a longer than usual dive one Saturday morning at Madison Blue Spring State Park in Lee, Florida. For several years and more than 100 cave dives together, we had built up our experience as a team and our time spent in this specific underwater cave system in northern Florida. We had slowly extended the duration and distance of our dives in this labyrinth of underwater tunnels that weaved throughout the karst limestone of the park, increasing our familiarity with the system while also practicing the skills that we had learned and continued to build on to be safe cave divers.
