Un trou dans mon cœur

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 […]

Construire un meilleur équilibre

LA PLONGEE SE FAIT dans un environnement dynamique, à la fois dans l'eau et hors de l'eau. Des situations difficiles et changeantes peuvent survenir même en se rendant sur un site de plongée. Les exercices d'équilibre peuvent vous aider à améliorer votre capacité à maintenir ou à retrouver votre stabilité sur un bateau qui tangue. Le port d'un équipement de plongée modifie la répartition du poids et le centre de [...]

Low-Visibility Diving

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, […]

Laryngospasme et anxiété

Q : Lors d'un entraînement à la plongée en piscine, je n'arrivais plus à respirer après avoir dégagé mon masque avec mon détendeur dans la bouche. Après être remonté à la surface, j'ai pris six à huit respirations sifflantes, puis j'ai pu respirer à nouveau normalement. Il est possible que j'aie inhalé de l'eau pendant l'exercice, mais mon instructeur et moi-même ne nous souvenons pas du moment ni de la manière dont cela se serait produit.

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 […]

The dive proved that this unique cylinder-shaped, carbon fiber and titanium five-person submersible can explore this wreck and was a […]

Short but Beautiful Lives

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 […]

Plus qu'une épaule douloureuse

I REMEMBER SITTING AT MY COMPUTER while thinking about all the ibuprofen I had been popping for the past 18 hours and wondering why I still had the dull, aching pain in my shoulder. Could this be more than soreness from carrying gear back and forth from our shore entry point or exertion from a […]
