Surviving Carbon Monoxide Poisoning While Solo Diving

Few people were diving in the freezing ocean around St. John’s, Newfoundland, Canada, in the winter of 1986. I still had my Poseidon Unisuit, which I had used for several years of commercial diving in British Columbia in the late 1970s.

Pay attention to local marine life bulletins and announcements. The best ways to mitigate jellyfish envenomation risk are to wear full exposure suits and avoid jellyfish when they are prevalent in the water.

A Little Detail

I TAKE A GIANT STRIDE off the back of the boat and splash into a cascade of tingling, magical bubbles. The sea’s embrace is chilly; I can feel the 74˚F water through my 5 mm wetsuit and thick 4 mm hood. My vision clears as the …
