The Spirit of a Dive Show

Along with California Diving News, we publish Dive Training magazine and the diving industry’s trade journal. So as a working member of the scuba industry, I have attended many dive shows. Heck, I was at the Long Beach show way back in its early days on the Queen Mary. Yet, until we took over Scuba Show I never fully understood them. After we purchased the Scuba Show from Kim and Dale Sheckler, and coming into our third year running it I’ve developed a profound appreciation […]

Careers in Diving: Professional Profiles Part 2

Probably the most amazing thing about the jobs people have who work in diving is that their careers are so varied. Pick a type of job, and there is probably someone who specializes in using diving in that job. There are doctors who specialize in diving medicine, lawyers who specialize in diving litigation, archaeologists who specialize in maritime archaeology, and the list goes on in many categories. As we traveled across California (as well as out of state) interviewing and filming professional divers we were […]

Seeing Spots: Studying the Two-Spot Octopus

While two-spot octopuses are not uncommon in Southern California waters, they are usually found tucked away in a crevice. Thus, when I came across one sitting quietly on top of a ledge, I took a photo. I expected the animal to flee when my strobe flashed but it did not. I took another photo and ventured closer. That’s when I noticed there were two octopuses, so well camouflaged they blended into the substrate.  The cephalopods were about eight inches apart, linked by an arm that […]

Your Basic Certification: Licensed to Learn

Like a lot of divers I participate in the diving community in several ways. One way is by serving on the Board of Trustees of the Reef Environmental and Educational Foundation (REEF). REEF’s membership is free, and we welcome anyone who cares to join.  REEF volunteers survey fish populations around the world, including many sites in California. The results are available to anyone that wants to use them, and a lot of scientists put REEF’s data to good use in a variety of ways.  Surveyors […]

Bunny Love: The California Brown Sea Hare

Although the California brown sea hare bears a faint resemblance to a rabbit, it is actually a very large sea slug. A member of the phylum mollusca and class gastropoda, it is a cousin of both nudibranchs and octopuses. Like nudibranchs, brown sea hares are hermaphrodites. Like octopuses, they can produce ink.  The brown sea hare has a reticulated color pattern that resembles that of the two-spot octopus, also found in SoCal waters. And despite the name, these animals aren’t always brown; sometimes they are […]

33rd Annual Avalon Underwater Cleanup February 22

The Catalina Island Conservancy’s 33rd annual Avalon Underwater Cleanup will takes place February 22, 2014. During the event, members of the diving community are invited to help clean the seafloor of Avalon Harbor. This is the only time diving is permitted in the harbor. Over the years, the cleanup has grown to become one of the most popular dive events in Southern California, attracting more than 500 divers who scour several sites to retrieve trash and lost items from the harbor floor. For the second […]

Careers in Diving, Part 1

Diving is an important tool for many people in their work. For some, such as sea urchin divers, it’s their most important tool for getting the job done. For others, such as police divers, it’s just one in a selection of tools. Over the past year, we have done video interviews with 14 different people who are professionally employed in careers that involve diving. We wanted to find out what they do, why they do it, and what they like and dislike about their jobs. […]

The Sequential Life of the California Sheephead

Many marine animals are hermaphrodites. Nudibranchs, for instance. It is thought that being able to mate with any same species creature encountered on the reef gives hermaphrodites a better chance of reproducing.  Many fish, gastropods and plants are sequential hermaphrodites. Instead of having both sexes mature in their bodies at the same time, they start life as one sex and become another later. Protandrous creatures change from male to female. Protogynous creatures change from female to male. According to Wikipedia: “About 75 percent of all […]

Homecoming to California Diving

I have just returned home from Orlando, Florida‚äîwhere I did not go to Disney World. However, I did attend the annual Diving Equipment Marketing Association (DEMA) trade show. This “wasn’t my first rodeo,” as a DEMA show attendee. I’ve been to this event thirty-some-odd times and it’s easy to fall into the “same show, different year” mindset.  But not this year. At this year’s show I felt a buzz of excitement, on the show floor that I haven’t noticed in a few years. What was […]
