According to Emperor Divers, the crew and guests executed emergency protocols swiftly, ensuring that everyone was brought safely ashore. Emperor Divers’ ground team has since been assisting those affected, ensuring they receive necessary support.

In the past couple of years, a string of accidents involving liveaboards, some of which sadly resulted in fatalities, have made headlines in the general press. This magazine did not report on the various incidents at the time, as we did not want to add to sensationalism or unfounded speculation. The incidents involved three liveaboards in the Red Sea and one in the Maldives.

Megalodon, the largest great predatory shark to have ever lived, dominated the oceans millions of years ago during the Neogene period. Despite its fame, much about its appearance and biology remains a mystery since its skeletons, made mostly of cartilage, rarely fossilised. However, this new research offers valuable clues.

The wreck was located approximately 60 miles (~97km) northwest of Whitefish Point in Lake Superior. Utilising Marine Sonic Technology side-scan sonar aboard their research vessel, the David Boyd, the GLSHS team made the initial discovery in late summer 2024. Subsequent deployments of remotely operated vehicles (ROVs) confirmed the ship's identity, revealing that the vessel had broken in two, with the bow section resting atop the stern in approximately 600ft (~183m) of water.

This groundbreaking research documents the behaviour in several oceanic fish species spanning three oceans. It describes the first recorded instances of fish using sharks and other fish to brush and scrape against, with the goal of freeing themselves of parasites.

I am chuffed to bits that Roz has finally received the recognition she truly deserves for her many years of dedicated service to the dive industry. Now lost in the fog of history, the day we first met was at some dive industry function; I believe it was a dive show in the United Kingdom around the turn of the new millennium. Roz has had such a long and storied career in the industry and, despite our long acquaintance, I don’t know the half of it.

The narwhal, often called the “unicorn of the sea,” has long fascinated scientists with its spiral tusk. Traditionally believed to play a role in mating displays or competition, new research reveals that the tusk, actually an elongated tooth, serves a far more dynamic purpose.

A study conducted by researchers from Florida Atlantic University’s (FAU's) Harbor Branch Oceanographic Institute and Canada's Department of Fisheries and Oceans (in partnership with the Inuit communities in Nunavut, Canada) has provided groundbreaking insights into narwhal behaviour. 

Sharks have long been the subject of fascination for scientists and enthusiasts alike and observations in the wild have revealed that their behaviour is far more complex than was previously assumed. But though the fossil record has provided a wealth of information about their prehistoric existence, it has rarely shown anything about their behaviour. 

This mysterious layer of water, between 200 and 1,000 meters below the surface, lies in  almost complete darkness, for the sun's rays can scarcely penetrate that far. Thus it is difficult or impossible to monitor using traditional tools. But while ships, buoys, and satellites can only capture a fraction of what’s happening below the waves, the seals’ foraging patterns can offer a far more expansive view of ocean life. 

Marine biologists are investigating unexplained deaths among great white sharks along the Atlantic coastline of the United States and Canada. Since 2022, at least nine carcasses have washed ashore, with necropsies revealing a common factor: meningoencephalitis, an inflammation of the brain and its surrounding tissues.
