Salmon Run

IN THE ADAMS RIVER IN BRITISH COLUMBIA, huge flows of sockeye salmon swim upstream to complete their life cycle, marked by the compelling need to return to their birthplace to spawn. Their unique journey from the ocean to their freshwater birthplace to reproduce is riddled with obstacles and dangers.

More Than Colorful Coral

I’M ALWAYS AMAZED at what people will do for love. My girlfriend, who is terrified of the ocean, announced that she wanted to learn to dive and then accompany me on a trip to Raja Ampat, Indonesia. I was thrilled. We come from different backgrounds and always look for activities we can do together.

Freediving Fins Reinvented

IN THE 1900s UMBERTO PELIZZARI was a young diver from Busto Arsizio, Italy, who was making headlines by breaking world records in constant weight and variable weight freediving. Needing an edge against his archrival, Francisco “Pipin” Ferreras, he sought advice on fins from a friend who was knowledgeable about innovative freediving equipment: Valerio Grassi, founder of Omersub.

Blame the Ballast

MARITIME TRANSPORT HAS MORE TO DO WITH CORAL DISEASE than you might think. Just like most animals, corals can get diseases. Researchers first recognized coral disease in the early 1970s. It has increased over time and become a significant threat in many areas of the world.

Recovering Color in Underwater Photography

IMAGINE SCROLLING THROUGH SOCIAL MEDIA posts or flipping through your favorite dive magazine. Your eye catches a photo of the most pristine waters you have seen. The sun is peeking through the surface, beautifully illuminating coral in pops of color in every direction. A diver overhead perfectly balances the composition.

BEFORE THE INTERNET WAS AVAILABLE, people read print magazines to learn about scuba diving — how to do it, what gear to buy, and where to go. For 51 years, from 1951 to 2002, the king of the genre was Skin Diver magazine. The undisputed queen of cover photography for Skin Diver was Geri Murphy.

Best Practices for Disinfecting Dive Equipment

AFTER THE INITAL SCARE AND LOCKDOWNS FROM COVID-19, divers soon started to explore ways to safely get back into the water. Disinfection has always been a consideration in diving, but we needed new standards to allay fears of uncontrolled transmission of infectious diseases.

Slow and Relaxed with Good Technique

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.

Freediving Risk Assessments

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.

Michael Lombardi: Immersed in Science

FISHING AND BEING ON THE WATER with family while growing up influenced Michael Lombardi to study marine biology. He and a friend got certified to dive during his junior year of high school, thinking it would be a useful tool for his desired field. Lombardi had no idea what professional diving meant or where it would take him.
