STOCKTON RUSH AND HIS TEAM AT OCEANGATE made history on July 10, 2021, when they reached the Titanic — at a depth of approximately 12,500 feet — in Titan, the only submersible of its kind. The dive proved that this unique cylinder-shaped, carbon fiber and titanium five-person submersible can explore this wreck and was a […]
PEOPLE WHO HAVE FILLED scuba cylinders, refilled oxygen cylinders, or boosted a gas mix are familiar with using flexible hoses. Some hoses are covered with a durable rubber or thermoplastic jacket, while others appear even sturdier with a braided stainless-steel mesh on the outside. Correctly specified hoses are rated to pressures of up to 6,000 […]
Q: During dive training in the pool, I couldn’t breathe after clearing my mask with my regulator in my mouth. After surfacing, I took six to eight wheezing breaths and then could breathe normally again. It’s possible I inhaled water during the exercise, but my instructor and I could not recall when or how that would have […]
WEATHER, SILTY SEDIMENT, time of day, or water movement are just a few natural factors among the range of possible causes that can influence the visibility at your dive site. Low-visibility diving can be quite enjoyable, but it depends on the circumstances and your comfort level. Why do people dive in low-visibility environments? Some divers, […]
DIVING TAKES PLACE in an environment that is dynamic both in and out of the water. Challenging and changing situations can happen even while traveling to a dive site. Balance exercises can help improve your ability to maintain or regain stability on a rocking boat. Wearing scuba gear changes your weight distribution and center of […]
I HAVE BEEN A CERTIFIED DIVER since 1986 and have logged hundreds of recreational and technical dives. Since 2014 I have primarily been doing technical rebreather diving with a close group of experienced rebreather divers from Northern California. During the summer of 2019, our group visited Lake Huron’s Thunder Bay National Marine Sanctuary in Michigan […]
Si le plongeur présente des symptômes et que vous lui prodiguez des soins, vous devez traiter les symptômes. Administrez-lui la plus forte concentration d'oxygène disponible et amenez-le à un centre de soins et de traitement définitif. Rappelez-vous que de nombreuses pathologies présentent des symptômes qui peuvent imiter le SCD. Ce n'est pas parce qu'une personne a plongé qu'elle souffre d'une maladie liée à la plongée. Lors de l'élaboration de votre plan d'action d'urgence, notez l'emplacement de la salle d'urgence la plus proche ou le lieu et la manière d'accéder aux services d'urgence locaux.
My buddy and I ascended to 20 feet for our safety stop. As soon as we surfaced I thought I saw the boat moving away from me but quickly realized I was disoriented. It felt like vertigo, but I managed to get on board the boat. I removed my gear and was talking to my buddy when I started involuntarily leaning forward until I lost my balance and collapsed face-down on the deck. I felt paralyzed and couldn’t get up.
In her work, Rachel Lance, Ph.D., focuses on extreme environments, particularly the effects of explosions. “The human body is fascinating, especially when it fails,” she says. “We are not naturally equipped to survive in a deep underwater environment, so I am fascinated with the idea of finding ways to do so anyway. Perhaps it’s my naturally rebellious side.”
