  • Cul-de-Sac Snails

    Snails, as a rule, grow up in a rather predictable pattern. As soon as they form their shells, they spend the rest of their development growing bigger and expanding these shells—but these shells just go round and round in circles. There are a few notable exceptions, such as cowries and tube snails, but in general, even these retain some sort …Read More »

    Your Brain as a Primary Piece of Diving Equipment

    It seems that in the past year we have been plagued by a rash of diving deaths, the most recent being the death of a very experienced research diver (over 3000 dives) on the wreck of the El Rey in San Diego the first weekend of the new year. During the past twelve months we have heard of divers who …Read More »

  • Sex on the Beach – Experiencing a Grunion Run, First Hand

    To the uninitiated, a grunion run can be considered the marine equivalent of a snipe hunt. Send some sucker out to a deserted beach in the middle of the night and tell him to wait for high tide when thousands of fish will magically appear on the beach. Yeah, right! Except that, in the case of the grunion, it’s true! …Read More »

  • One of the Cutest Fishes Found All Around the World

    Almost everybody would call snipefishes cute. Perhaps a major reason for this is that the approximately one dozen species of this family Macrorhamphosidae all have big noses. Technically called “snouts,” these protruberances can be as much as a third of the fishes’ entire body lengths and are usually tube shaped. And way at the far end of these snouts are …Read More »

  • The Single Dive Time-Warp

    On a recent dive trip to Catalina Island I was sharing the boat with two basic classes, visiting the island and its underwater realms for the first time. While the kelp was thick, marine life abundant, the water clarity this day left something to be desired. It was an unusually poor day for Catalina with visibility averaging about 20 feet. …Read More »

  • Getting the Edge in Photo Contests

    I had the recent privilege and honor of co-judging the 38th annual International Underwater Photographic Contest conducted by the Los Angeles Underwater Photographic Society. I was quite impressed with the professional standards of the contest handling. But even more impressive was the quality of the entries. There were a total of 1,244 photographic entries coming from underwater photographersaround the world. …Read More »

  • Yukon Update: 9 Months Down and Growing!

    It has now been around nine months since the 366-foot long Canadian destroyer Yukon quietly slipped beneath the surface in the dark of night off San Diego. After nine months, life has arisen from this event into a new birth. If you have not dived the Yukon lately, you are in for a pleasant surprise! The ocean as already begun …Read More »

  • Those Remarkable Bladder Chain Kelps

    All California divers know and greatly admire giant bladder kelp (Macrocystis pyrifera). There is nothing like being 30 feet beneath the surface of the water and looking up in awe at the rays of light filtering down from above, glistening through the golden leaf-like blades of the giant kelp in a kelp forest. Yet the kelp forest is home to …Read More »

  • More, Bigger Abs: Taking Abalone Diving to the Next Level-Tips for Successful Hunting from Seasoned Veterans

    Hunting for abalone is the most common excuse for getting wet in Northern California. These tasty mollusks are quite abundant, and are not difficult to find with a little knowledge and practice. In April of 2000 CDN published a primer for new ab hunters. In this issue we discuss how more experienced divers can come home with more and bigger …Read More »

  • Improve Your Photography: Lighting Angles for Clear Photos

    I once met a photo buyer who was looking for underwater images with “no water in them.” What they really meant was they wanted clear images as if they were taken in air and not underwater. In-air visibility is measured in miles and clear images are easy to achieve. Underwater, this task is more difficult due to water suspended particles. …Read More »
