MY FELLOW DIVERS WERE ECSTATIC AFTER A TWILIGHT DIVE on the Okinawa wreck near Pompano, Florida, in early June 2019. I was shooting wide angle and hadn’t paid much attention to small creatures during the dive, but they had found the holy grail for macro photographers: nudibranchs — in this case, regal sea goddesses (Felimare […]
WHEN IT COMES TO THE OCEAN, we know when to go and when to stay away. If it is standard practice to check conditions before a dive, shouldn’t we ask […]
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 […]
If the diver is symptomatic and you are rendering care, then you need to treat the symptoms. Give them the highest concentration of oxygen available, and get them to definitive health care and treatment. Remember that many conditions show symptoms that may mimic DCS. Just because someone was diving does not mean they have a dive-related illness. When creating your emergency action plan, note the location of the nearest emergency room or where and how to access local emergency services.
