Oxygen sensors, or "cells," which are used in rebreathers have a limited shelf life and need to be replaced every 12 to 18 months. However, new ones are currently not available to the dive community.
In the United Kingdom, oxygen cell manufacturers have been mandated by the UK government to supply cells to the medical industry, leaving the dive community with back orders.
I was greatly saddened by the loss of Lad Handelman, who passed away as a result of a heart attack on the evening of October 26, 2020. Though most people knew him as one of the larger-than-life giants and pioneers of commercial oilfield diving, few knew that he was a key advisor for my magazine aquaCORPS: The Journal for Technical Diving and the tek.Conferences in the early 1990s.
I first discovered freshwater eels in an estuary pool by the sea in Tahiti. There were usually about eight of the thick-bodied creatures, each over two metres long with triangular fins at their gills and vertically flattened tails.
Dry bags. We all need and use these invaluable bags to keep our personal possessions dry during a dive, or to stash wet kit post-dive.
—A rare look behind the making of an iconic image. From conception of the idea to the execution, you will be surprised how little of it was left to chance.
I went to Oman to look at coral reefs that are regenerating from damage caused by cyclone Gonu in June 2007. Divers are just beginning to learn of the Sultanate of Oman; it’s becoming yet another destination to consider. A country with a 1700km coastline extending from the border with the Republic of Yemen in the south to the Strait of Hormuz in the north.
Sea glass has become very popular as a component in jewelry, chimes, sun catchers and ornaments. Tumbled by the ocean waves, sea glass comes from tossed bottles and jars that have found their way to the sea. The sand and surf softens the edges of the broken glass as it tumbles in the waves creating smooth, frosty pieces of sea glass, or beach glass.
The Oldenburg, which was originally named Pungo, was built in 1914 to carry bananas between Cameron and Germany. It was drawn into World War I in 1915, put into German service and rebuilt as a raider ship. René B. Andersen shares the story of the ship and takes us on a dive to the wreck.
As many divers face travel restrictions during the coronavirus pandemic, our contributors highlight the often overlooked or unsung yet intriguing diving that can be found in one's own backyard.
We asked our contributors what their favorite wreck dive was and they answered with tales and images of remarkable wrecks of all sorts and the artifacts found on them, giving first-hand accounts of their experiences on these underwater time capsules as well as glimpses into the history of each wreck.
Outside my window, the South Atlantic lay unbroken—an azure expanse of ocean below and sky above. Three hours after passing the Namibian coast, a lone patch of clouds appeared on the horizon. As we approached, I could just discern patches of green peering through. Atop a narrow ridge, a tiny strip of runway appeared, the sheer drops at each end plummeting to the sea.
Adobe Photoshop is the number one tool for image editing and provides a large number of editing tools and options—far too many of them actually. But the good news here is that, for editing our underwater images, we only need a few.
