Today, when you execute planned decompression stop dives using mixed gas and multiple gases, with open-circuit or closed-circuit hardware, in the caves of Florida, Russia or Mexico, the wrecks of Scapa Flow, the Great Lakes or Truk, the abandoned flooded mines of Finland and South Africa or the walls of Palau—whichever of the alphabet soup of agencies trained you in this kind of diving—you will be carrying the same equipment, configured in one of a few recognised, accepted and well-tried ways, and using similar combinations of gases, decompression tables and procedures. Simon Pridmore has the story.

Maërl is one of those species that is indicative of clear, clean waters. Whilst it is known locally as Scottish coral, maërl is not a coral, but it does have a hard, bone-like structure. It is actually algae, and its beds can be quite common in a huge number of locations, from the Mediterranean to Scandinavia. Lawson Wood shares his insights and photography of this special species.
It made headlines worldwide. Five Italian divers died in a cave in the Vaavu Atoll in the Maldives. On behalf of DUIKEN magazine (the biggest diving magazine of the Netherlands and Belgium), editor Patrick Kranenbroek spoke with Laura Marroni, CEO of DAN Europe, and Sami Paakkarinen, a member of the Finnish recovery team.
During her study of blacktip reef shark behaviour in Tahiti, ethologist Ila France Porcher came across a sick male shark, steadily growing thinner. As she brought extra food and medicine to him, she noticed other sharks showing a remarkable awareness of the situation not normally expected of sharks.
In Magdalena Bay on the Pacific coast of Baja California, recent warming of the seas is affecting and amplifying one of the most spectacular events in nature: Mexico’s marlin run. Silke Schimpf reports.
In March 2024, underwater photographer Patrick Kranenbroek was visiting Saronde Island in Sulawesi, Indonesia. Here, Anke Andree, the managing director of Blue Bay Divers at Saronde Island Resort, told him that she also owned and operated a dive liveaboard for the past 14 years: KLM Sunshine. “We want to start exploring new dive areas south of Lembeh,” she said. “Would you like to join? We’re going all the way to Bolsel.” One year later, the time had come. The Lembeh – Bolsel – Lembeh trip began, and Patrick was on board.
Located in the Coral Triangle, South Halmahera offers divers some of the most biodiverse reefs on the planet. Here, Pierre Constant visits Sali Kecil to explore this underwater paradise.
The idyllic islands of the northern Maldives, located in the Indian Ocean and far from the tourist crowds, are more untamed than their southern counterparts. Here, the ocean seems wilder, and underwater wonders await. Underwater photographer Kadu Pinheiro recounts his expedition adventure there.

The winners of the international Lens Beyond Ocean (LBO) Photo Competition 2026 have been announced by the organisers of the Malaysia International Dive Expo (MIDE), which hosts the contest. The winning images were displayed at the expo, which took place at the Malaysia International Trade and Exhibition Centre (MITEC) in Kuala Lumpur from 5 to 7 June 2026.
From PortMiami to Honolulu and the Gulf of Oman, growing evidence suggests some corals are thriving in places long considered unsuitable for reef-building species, challenging assumptions about what healthy coral habitat should look like.
Returning to the Malaysia International Dive Expo (MIDE) after an absence of several years was something of a revelation. X-Ray Magazine has proudly supported the show as a media partner since its inaugural edition in 2006, but having local representatives in Southeast Asia meant I had not attended personally for quite some time. That made this year's 20th anniversary edition all the more eye-opening.
A major victory for shark conservation has been won for the Red Sea. After years of pressure from environmental groups and marine conservationists, Egypt has prohibited shark fishing in the Red Sea, which is one of the most important marine ecosystems on Earth.
Technical divers removing ghost nets from an offshore wreck between Sicily and Tunisia captured what may be the first diver-filmed underwater footage of an adult great white shark in the Mediterranean.
Researchers have confirmed the identity of a World War II submarine wreck in the Kuril Islands, resolving a decades-old mystery surrounding the loss of USS Herring and its crew of 83.
More than 300 amphorae recovered from a 5th to 4th-century BC shipwreck off Calabria may help archaeologists reconstruct ancient wine-trade networks across Magna Graecia and the wider Mediterranean.
Divers around the world are carrying an extraordinary archive of marine biodiversity on their cameras and hard drives—and many may not realise just how important their photographs could be.
Italian prosecutors are seeking dive equipment, cameras and records from the Maldives as investigators attempt to reconstruct the fatal cave dive that claimed six lives in May.
Researchers have identified a previously unknown mechanism that shows how extreme ocean heat can disrupt the microscopic structures corals use to breathe.
In the open ocean, there is nowhere to hide. Far from reefs, caves, or seaweed, countless marine animals drift through clear blue water, exposed from every direction. Above them is sunlight. Below them, darkness. Predators may approach from any angle. For life in this vast transparency, survival depends on a single challenge: how not to be seen. And so evolution has produced some of the strangest forms of camouflage on Earth.
A week of coordinated search and recovery operations in the Maldives has concluded following the deaths of five Italian divers and a Maldivian rescue diver in a flooded cave system in Vaavu Atoll.
In the dim, blue waters of the ocean’s twilight zone, long, transparent ribbons drift through the darkness. Some pulse softly with bioluminescent light. Others trail delicate tentacles, like threads of glass. They are the mysterious siphonophores—creatures that are not just one animal; they are an entire colony, living as a single being.
The ocean appears vast, open, and full of life, but in certain regions, something essential is missing. There is no colour to mark it, nor sound to warn of it, and no boundary to be seen. Yet, within these waters, oxygen has thinned to the edge of survival. These are the oxygen minimum zones.
The wreck of the US Coast Guard Cutter Tampa, lost with all hands during World War I, has been discovered off the coast of Cornwall, bringing closure to one of the service’s deadliest losses.
