The Marine Conservation Society (MCS) has downgraded mackerel from a sustainable seafood choice to a cautionary amber rating, urging consumers to switch to herring or Cornish sardines instead.
A groundbreaking study led by Dr. Michael Byrne from the University of Missouri’s College of Agriculture, Food and Natural Resources is pulling back the curtain on why mako sharks, the racecars of the ocean, aren’t venturing where they used to, and it’s all about one critical factor: oxygen.
The issue is that if using Air mode and the Nitrox mode gas has been programmed to something other than air (21%), then that programmed gas is used while diving. This could result in a less conservative dive plan than is appropriate.
Prevention: If using firmware v34, do not use single gas Air Mode. Instead, use the single gas Nitrox Mode with 21% gas programmed.
Updated firmware for Tern and Tern TX will be released Monday April 14, 2025. Please check our website for the newest version.
A study conducted around Andros Island in the Bahamas revealed that some individuals display remarkable site fidelity, choosing to stay close to home rather than embarking on extensive migrations.
The International Association of Nitrox and Technical Divers (IANTD) and Scuba Educators International (SEI) have joined NAUI in embracing the Powered By DAN program.
Through Powered By DAN, dive training agencies incorporate the skills and standards of DAN’s basic life support, CPR, oxygen administration, and other courses into their first aid training.

The blue-lined octopus (Hapalochlaena fasciata) is a fascinating species, known not only for its striking blue markings but also its venomous hunting and self-defence strategies. The neurotoxin it produces is called tetrodotoxin (TTX) and it is incredibly potent—far more toxic than cyanide.
Recent changes in US immigration enforcement have prompted updated travel advisories from Canada, Germany, Denmark and Finland. These nations have warned citizens of an increased risk of detention and secondary screening, particularly for members of the LGBTQ+ community and those with non-standard travel documentation.
Unlock the Depths: Your Buddies brings CCR Divers together for Exploration
Operation CCR is taking place this year from April 19-25, the highly anticipated event will once again bring together divers and industry experts for the most immersive experience.
What to expect:
Once upon a time, when we were drafting and tinkering with the design and editorial profile of this magazine before it was launched, I had already made the observation that American dive magazines focused predominantly on US dive sites, the Caribbean and some Pacific destinations, while European magazines were mainly centred on local dive sites, the Mediterranean and the Red Sea, with the occasional mention of the Maldives or Thailand.
The moment, captured on video by researchers from the Auckland University of Technology, has quickly attracted international attention.
While octopuses are known for their intelligence and problem-solving abilities, such behaviour is highly unusual. Researchers suggest the octopus may have been using the shark as cover, attempting to avoid predators or navigate more efficiently through the water. It is also possible the octopus was defending itself after an attempted predation by the shark.
