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.

Vis Island, Croatia

THE CRYSTAL-CLEAR EASTERN ADRIATIC SEA is promising and seductive. The tiny islands, with their rocky beaches, upright cliffs, and hidden lakes, offer a variety of environments and ecosystems that are among the Mediterranean’s most intact and pristine. The southern part of the Adriatic’s Croatian side has steep, rocky plateaus with plenty of bridges, cracks, and caves. The sea has opened gaps in the porous rocks, carving and shaping cathedrals entirely built of limestone.

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.

Una-Una: A Hidden Paradise

Everything changed for Una-Una on July 14, 1983, when a volcanic eruption destroyed the central hub of Indonesia’s Togean Islands in central Sulawesi. Lava covered 90 percent of the island, and thick, black smoke rose into the sky more than 9 miles high. The Indonesian Navy had evacuated all 7,100 inhabitants when the volcano gave signs of its impending eruption, preventing any loss of life.

Commercial Diving Safety

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. 

Healing Without Worry

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.

Komodo Islands Close Encounter

BEING STUNG BY A LIONFISH is like being bitten by a poisonous snake. I found that out the hard way.

Wolf-Eels

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.

Connecticut: From the Shoreline

BETWEEN NEW YORK AND BOSTON LIES HARTFORD, the heartbeat of Connecticut. Visitors there can tour the Mark Twain House, Harriet Beecher Stowe Center, and the Wadsworth Atheneum Museum of Art. Beyond the city, trees and hills make way for fresh and coastal waters teeming with macro life.
