Dive training agencies track the number of certifications they issue, but the number of active divers worldwide is still unverified. As dive research grows, identifying the denominator for the dive population is increasingly important.
Planning group travel through a local dive shop can help prevent people from taking advantage of you, because the dive shop has likely researched the vendors they use and may already have experience with them.
What diver isn’t enchanted by an octopus, especially a beguiling beauty with the reputation of an assassin? Even though we searched for legendary blue-ringed octopuses across their territorial waters of the Asia-Pacific, it took five years before we made our first sighting in Lembeh Strait.

Strength training can benefit divers, who need strength to wear and transport heavy gear. Other benefits include greater bone density, increased metabolism, and cardiovascular strength.
As I drove west past Port Alberni on Vancouver Island, British Columbia, on my way to a photo shoot, I watched in disbelief as the temperature gauge in my vehicle rose from 64°F (18°C) to 113°F (45°C). I thought something was wrong with my gauge, but a local radio station reported the same temperature. British Columbia had record-high temperatures throughout the province that week in June 2021.
When I dive in an unfamiliar area, I tell the dive operator I want to start at their best spot — the site with everything. If I get bored with that, maybe I’ll try other sites. If you came to my home turf on the Kona Coast of Hawaiʻi Island and asked me for the site that has everything, I would send you to Ripoff Reef.
It was 2004, the dawn of digital photography, and I was conflicted about whether to shoot film or digital. I had brought housings for both cameras with me to Thailand. Carrying two housings on a dive was ponderous, but I could manage it if I didn’t take two sets of strobes. My solution was to rig both housings with wet connectors called EO pigtails, which went into the regular sync socket, allowing me to connect and disconnect my strobes underwater.
During a recent dive trip to Chuuk, I really wanted to see the San Francisco Maru wreck. I never imagined, however, that I would have a near-death experience immediately upon entering the water.
To clear up any confusion divers may have about patent foramen ovale (PFO), I will share how I explain the condition to patients.
