The World Of  Fishes: A Primer for Divers

Fish fanatics. That term is an apropos way to describe a lot of divers. Those of us that fit the description love the seemingly endless variety of shapes and colors found in fishes. We are fascinated by their antics and the ways some species blend into their environment while others standout. We get a charge out of learning about and watching their courtship rituals, displays at cleaning station, the challenge of trying to identify and photograph them, and so on and so forth. But ask […]

Our Changing Oceans: California’s Marine Ecosystems in Flux

Divers have a front row seat to witness the profound changes that occur in our ocean world. Back in March I wrote a little piece about the seasonal changes we all enjoy each time our planet takes a lap around the solar system. This issue is about the longer term, and perhaps, more persistent changes that are happening to our California reefs. Outside of the annual changes in our seasons there are multiyear weather patterns that occur regularly, but not predictably. The most well known […]

Suit Yourself: What You Need to Know — Thermal Protection for California Diving

The rich California coastline offers a bounty of marine life and a range of dive locations to suit every diver. We’ve got kelp beds, rocky reefs and wrecks. We’ve got offshore islands reachable only by boat, and we’ve got some spectacular shore diving, too. We can hunt and collect our dinner, or capture stunning images with a camera. In other words, we’ve got options. When it comes to equipping ourselves with the proper exposure protection needed for safely and comfortably exploring our decidedly temperate waters, […]

It’s Just a Phase: California’s Quick-Change Artists

Newborns of many species — horses, kittens and elephants for example — look like miniature versions of their parents, although they are universally a lot cuter. It is, of course, a great advantage to be cute as cuteness might help a mother bond to its young and lessen the odds of animal parents abandoning their young should they misbehave. Other animals start out looking nothing like their parents and may go through one or more developmental phases before assuming the final “you look just like […]

In Memoriam: California Diving Great Bob Cranston

The California diving community lost one of its greats recently, when on June 2, 2016, underwater cinematographer Bob Cranston died. He is remembered both for his cinematic achievements and as a pioneering shark diver. Bob Cranston, Underwater Filmmaker By Howard Hall It was the winter of 1993 and the weather was clear and calm at Catalina Island. But there was some current running through our dive site. “Do you think we can do this?” I asked Bob. Bob laughed and said, “Yeah, I think it’s […]

Diving Medicine is Different: DAN and the UCSD Diving Medicing Clinic

A dentist is a doctor the same as psychiatrists and proctologists are doctors. But these doctors have vastly different areas of expertise. There are times when our healthcare needs can be met with a visit to our “family doctor,” a general practitioner who specializes in providing comprehensive health care. And then there are times when we might need to consult with a specialist. For us divers, this might include a consultation with or examination by a diving physician — one who is trained in undersea […]

The Dive Tribe is Gathering: Why You Should Join Us at the Scuba Show

By Cathryn Castle Human beings are tribal by nature. We tend to seek the company of people with whom we share common bonds. Whether we’re connected through a common language or philosophy or passion, we experience a sense of comfort and ease when we’re with “our tribe.” For some folks, it’s mountain climbing or stamp collecting, but for us, it’s getting out on — and under — the water as scuba divers. When we see that little red and white dive flag bumper sticker on […]

The Business of Passion– The Diving Industry, Seen Through a Show

If you had a chance to sit in on casual conversation with a group of dive industry executives, you might hear someone comment about how the diving business is run by hobbyists. By that, they mean people who fell in love with diving and found a way to make a living at it. The conversation usually winds up with the group wondering how much farther along diving would be if it was run instead by a solid collection of business school grads. They stop short […]

Going Pink in the Deep Blue: Scuba Divers Unite to Fund Breast Cancer Research

Dive into the Pink
Dive into the Pink

By Allison Vitsky Sallmon   In 2003, I was many things — 33 years old, a postdoctoral fellow at a Boston-area university, a veterinary researcher, a scuba diver, and a workout fanatic. What I wasn’t, was someone with a lot of free time. So on the October day that I placed my hand on my left breast and found a distinct mass, I was more annoyed than frightened. Still, instinct told me to get it checked, so I made an appointment at the student health […]
