Five Italian tourists have died while exploring underwater caves 160ft below the surface in the Maldives.
The group had set off on a diving expedition on Thursday morning to explore the Vaavu atoll, according to local media.
Authorities received reports of the divers' disappearance at around 1.45pm local time after they failed to resurface at around midday.
During the search and rescue operation, their bodies were discovered.
According to initial reports, the five tourists had boarded the 'luxury' Duke of York yacht, a foreign-operated live-aboard diving vessel, and they disappeared near Alimatha, one of the atoll's most popular diving spots.
One of the victims has been named by Italian newspaper Il Messaggero as 51-year-old Monica Montefalcone, a respected marine biologist, TV personality, and professor of Tropical Marine Ecology and Underwater Science at the University of Genoa.
Her 20-year-old daughter, Giorgia Sommacal, also died.
The other three victims have been named as Muriel Oddenino of Turin, Gianluca Benedetti of Padua, and Federico Gualtieri of Borgomanero.
Montefalcone and Oddenino were colleagues at the University of Genoa.
Montefalcone worked at Distav, the Department of Earth Sciences. In the Maldives, she was the scientific director of the island monitoring campaign, according to Italian reports.
Benedetti was an operations manager, as well as a diving instructor and boat captain.
Police have launched an investigation into the tragedy, but the cause of death remains unknown at this time, and no official statement has yet been released.
Local officials said it was the worst single diving accident in the nation of 1,192 tiny coral islands scattered some 500 miles across the equator in the Indian Ocean.

By oxygen toxicity they are referring to excess depth on nitrox.
Nitrox standard mixes are 32 percent or 36 percent; max of 111 feet or 95 feet, respectively, beyond which the partial pressure of oxygen exceeds the safe limit. 160 feet is not an oxygen-toxic depth for air (21 recent oxygen) but their boat was known for providing divers with nitrox. For air the safe limit (the same partial pressure) is about 187 feet in salt water.
The fact they may have been exploring a cave may have made it more difficult to react quickly to early signs of oxygen toxicity - delaying any effort to start an immediate ascent. It’s also a possibility that others delayed their ascent trying to help the one that was incapacitated first.
We probably will never know.............
Mr. Ballen (youtube) had a story about some guy that wanted to cave dive. Might have been this cave. I don’t fully recall it, but the guides with the specialized gear were booked out a few days, but the guy had a plane to catch.
So he used his regular gear. And filmed the entire thing. IIRC he got down to a certain depth, and then just kept sliding down the sloping cave floor to his death. Still alive and conscious and trying to recover I think, but it wasn’t effective and he just kept sliding deeper and deeper.
He didn’t make his flight. And iirc they recovered his camera and it is on the internet now.
“They died doing something they enjoyed.”
I’m pretty confident they didn’t enjoy the dying part...
How about white water rafting?
It was indeed a Mal dive.
Terrible tragedy, completely avoidable. Very poor judgment.
I don’t do out of country “experiences” like this especially if it involves underwater anything. I’m always gobsmacked when people go overseas or to some Caribbean Island and pay lots of money to do something with little to no training and put their lives at risk not knowing anything about that country’s regulations, license requirements, etc. for operators of said experience.
Before diving excursion ask self feel lucky.
Friend who cave dives told me a story some years ago about two brothers diving caves in a Florida spring. They got lost, then spent the rest of their air carving final messages on their scuba tanks. Turned out their lights, and grasped hands...that’s how they found them. I’ll never do caves or wreck penetration.
I’m pretty confident they didn’t enjoy the dying part...
True to both but it was pretty quick.
I’m guessing this is what happened too
