TO FIND THE FIRST DESCRIPTION OF A LARVAL PEARLFISH in the wild, I had to search back to the early 1980s annals of blackwater diving and Christopher Newbert’s account of drifting 40 feet down a lighted downline tethered to a dinghy bobbing on a night sea somewhere off the Kona, Hawaiʻi, coast. The story appeared […]
TRITON BAY, INDONESIA, was one of the last places I visited before the COVID-19 pandemic struck. Looking back, part of me wishes I would have been there instead of at home when the world turned upside down and international dive travel became almost impossible. An extended sabbatical in the middle of bustling hordes of fish […]
Just before sunrise I make a cup of strong Indonesian tea and feel the familiar rush of anticipation that always builds when I dive where no one else has. From the liveaboard’s top deck I squint at a string of islands— just green dots from here — that stretch offshore from the Fakfak Regency …
“Pura vida!” our dive guide, Sergio, exclaimed with a relaxed smile. Eight dive buddies, Sergio, and I just had an incredible experience: A 35-foot-long whale shark swam a few feet over our heads at one of the better-known dive sites at Cocos Island, Costa Rica. It silently came and went, seemingly carefree, like a giant spotted apparition sliding out of sight into the deep blue.

I WAS 13 YEARS OLD THE FIRST TIME I WENT SCUBA DIVING. My family was on a trip to Cancun, and my dad took me and my sister, Carrie, who was 11 at the time, for a scuba lesson. We did a low-risk resort-style dive, going no deeper than 25 feet. But we loved the […]
DAN EMERGENCY SERVICES RECEIVED A CALL via satellite phone from a liveaboard anchored off a remote island in the Galápagos. A DAN member was concerned about their bunkmate exhibiting symptoms following the day’s dive activities. The diver had completed four dives that day. Although she began to show symptoms following the second dive, the inexperienced […]
SURFACE MARKER BUOYS (SMBS) AND DELAYED SURFACE MARKER BUOYS (DSMBS) are common and essential safety devices. These brightly colored, inflatable tubes, sometimes called safety sausages, are critical pieces of equipment that divers should take on most dives. Divers most often use them as signaling devices to mark their locations below the surface and alert boat […]
IN THE PREVIOUS ARTICLE, we settled on the recommendation that equipment used to control any breathing gas mix containing 25 percent oxygen and above at typical scuba cylinder pressures should be designed and considered suitable for oxygen use. Possible debates aside, we’ll examine what oxygen cleaning means. How often should gear be oxygen cleaned, and […]
