- Опубликовано: 12 ноя 2015
- The Mediterranean Sea is a world of impressive diversity where ocean sunfish and whales live side by side, and colourful corals provide a home for smaller creatures. But human beings have left their mark here for thousands of years: ancient shipwrecks and fighter planes from the Second World War litter the ocean floor, while until recently raw sewage was fed straight into the sea. The impact has been devastating - today the Mediterranean is an ecosystem on the edge. But there is a glimmer of hope as measures to protect the sea from pollution and excessive disturbance are being put into place.
Sandrine Ruiton from the University of Marseille specialises in research on artificial reefs to build up the lost marine biodiversity near cities like Marseille, one of the Mediterranean’s busiest ports. Until recently it was responsible for seriously polluting the surrounding Mediterranean Sea. Christian Petron himself has been instrumental in raising awareness of this ecosystem in dire straights. His own 30-year-old archive footage shows the extent of the pollution in graphic detail.
Both Sandrine Ruiton and Christian are involved in the hugely successful ‘Prado Reef 2006’ project, which is designed to repopulate the local waters by encouraging the colonisation of new reefs. Even old shipwrecks and fighter planes turned into artificial reefs and first indications offer grounds for cautious optimism.
But to be able to accurately assess the success of these artificial reefs, detailed population counts are absolutely essential. But their accuracy is questionable when carried out by divers with conventional equipment - reef creatures are notoriously shy and many are likely to hide at the approach of a noisy diver. So Sandrine Ruiton wants to find out if Frederic can achieve more accurate population counts on these fragile reefs by being less intrusive. His ability to move and behave almost like a fish without any cumbersome diving equipment allows him closer access without frightening the wildlife off.
His first destination is the wreck of an freighter, sunk after world-war 2, closely followed and observed by Christian Petron. The collection of creatures found here are delicate and extremely cautious. But this dive also poses real challenges for Fred: diving in a wreck brings particular dangers with it, especially for a freediver. Nevertheless, he is determined to press on with his attempt to evaluate the state of Mediterranean marine wildlife.
The artificial reef population surveys are only part of the reason why Frederic has come to the Mediterranean. He also works together with Dr. Pierre Chevaldonne, a scientist at the ‘Station Marine D’Endoume/Marseille’. Both are interested in an underwater cave that could be invaluable to modern science.
Organisms and animals that are usually associated with much deeper waters thrive in this deep dark cave. In particular a collection of sponges could be of interest, not just because they provide an endless supply of biomarkers that are very sensitive to environmental changes: they are also highly relevant for modern medicine. Sponges are known to provide AZT (Azido-Thymidin) - currently one of the most used medications for the treatment of AIDS and in the fight against cancer. The sponges generate these substances as dangerous chemical weapons against predators or as a defence against harmful bacteria.
The research team is renowned for their work on sponges, but the breathing bubbles emitted by conventional drivers would collect at the cave ceiling and gradually kill the cave dwellers.
But Frederic’s approach is very different. By holding his breath, he can ensure that the sponges and other cave organisms are not threatened. He is able to explore the cave in detail and report his findings and bring samples back to the research group. This research can provide ground-breaking insights into modern medicine, as well as giving an indication of the health of the Mediterranean waters by examining the sponges’ biomarkers.
Together, Frederic’s involvement in the artificial reef projects as well as the underwater cave exploration are extremely valuable contributions to the quest to document and protect the diversity of Mediterranean marine wildlife. He is in a unique position to access and approach the wildlife, that cannot be replicated by using conventional diving methods, and as such is an incredible opportunity for the scientists to gain a new window to the underwater life of the Mediterranean.

I just love these guys, the FREE divers, they are quite amazing, almost superhuman IMHO. While watching the section in the cave, and rebreathing in the trapped air source inside the cave, it struck me that they "could" take down a couple of air tanks, and release them into that space, thereby providing them with a good source of air replenishment to let them search even further away from that point, while having good air to stock back up on for their return to the surface world. ?
Excellent program. Im a keen scuba diver and its sheer stupidity of the dive operators to allow approx 150 divers on one site. I hope the Mediterranean continues to recover.
an rebreathers are not a thing in the Med..
I don't dive nor do I live anywhere close to saltwater but that doesn't stop me from learning how fragile these places are. I am very happy to see people that are around to look at these places with the main goal as not to change or damage them but in fact to protect and make better the underwater world life.
The world has been taking from these places forever and only a few have worked to give back to these places. Thank you for uploading this program,, it's education for many like myself that have to declare the old adage ,, out of sight, out of mind.
If not for these programs many like myself don't even think about what is going on meters below the waves.
Spectacular documentary! :)
These dudes are crazy, but you have to respect their ability to do this, i would be lucky to even go down and touch the bottom and come straight back up without dying at 50 meters
I am in awe at the abilities of the free divers to make such descents but wonder quite how much loiter time they have before needing to ascend.
The free divers, unencumbered by scuba gear look very graceful, though particularly vulnerable.
Free divers clearly have a masterful knowledge of the science of breathing at depth, and of their own capabilities to be able to achieve what they do, which is something really quite remarkable.
I LOVE THESE SHOWS THERE AMAZING THE FREE-DIVERS ARE ABSOLUTE INCREDIABLE OMG
it s been only 1 min the documentary is ON and i'm already so excited !!!
THIS IS AN AMAZING DOCUMENTARY THANKS VERY INFORMATIVE, THANKS
Impressing, skilled Divers, hope fore more Episodes : )
Woow, so informative
So peaceful to watch
Free diving is way too stressful!
It's acually the exact opposite
Amazing free divers! Great videos!
Woe dude was under 62mins. With only little oxygen on 2nd breath great documentary
Wasn't it dangerous to breath at that depth as seen on 34:00 minute of video?
it takes me about half an hour just to get a victoria sponge in aldi and hes worried about 3 minutes.
Looking for a second time. Hope he didn't done any dangerous dive like that since.
He has a safety diver that means if mart needs air he can get it DUH !
Great documentary! Now can we talk about the mind blowingly enormous amount of chemical warfare agents that have been dumped by the USA all over the plantet...from Okinawa to the Bahamas, the USA has dumped catastrophically huge amounts of sarin, cx, mustard gas etc etc into waters...estimates of 300,000 tons are conservative. So when I hear an American accent talk about the pollution of the Mediterranean by raw sewage...I just think of the barges containing mustard gas that left the USA every month for 10 years and dumped their contents between Florida and the Bahamas.....
And unlike poo...that stuff just forms a toxic gloopy dense mass that kills everything that comes into it...and may eventually come to the surface....well done!
Very deceptive title. The doc concerned exclusively the (relatively murky) sea around France--primarily Marseilles. Impressive free dives, but nothing much else to write home about.
notice the fish :U
Does anyone know why the coral diver would choose corals with polyps on them rather than the coral right next to it that didn't have any polyps on it? Shouldn't they try to find dead corals as not to kill the polyps? Or were the ones without polyps just starting out or do the polyps hide? Anyone who has actual knowledge is love to know more about how these divers pick the corals and how they should pick corals!
Have they ever heard of rebreathers?
Sure they have but the free diving gimmick would have less impact.
No, they have not. They have waited for you to tell them in an anonymous comment on RUclips
Do we actually explore the sea???
The raw sewage segment from France reminded me of how India still is polluting its rivers and waterways with raw sewage every day. Humans have no regard for the planet's oceans, seas, rivers, lakes, ponds, streams, and no respect for the life contained within these waterways. The people who work at conservation don't get enough respect from the multitudes of others.
'Protected and endangered species ' diver proceeds to kick it away from him..
Don't buy red corail !
Please say more it is important to let people know!
is this real???
Yeah they're humans and they practice it for a young age that's why now they can dive realy realy deep in one breath .
Wow
I can argue the government anticipated the coastal waters dying but did it anyway because it's the poor middle class who gets their food from there. The government officials are rich enough to get it elsewhere. The only people hurt are the locals who don't have transportation or means to get food from elsewhere like the rich.
Nice video but deliberately paints all SCUBA Divers in a bad light. Its like free divers are the only ones to be unobtrusive. A good diver is just as environmentally friendly. All I hear is were amazing, were amazing :( Stop banging your drum, its a good subject and film so less propaganda please.
also filming and praising the coral harvester! really biased, otherwise under water is amazing!
Dont foget the 60,000 barrels of nuclear waste barrels dumped offshore by fFance, should be retrieved and used, not let to burn the whole Med sea.
i get what your saying they think they are on the same level as fish when they are not and never will be.
lol 30:29 get da fuck outta here
Jccc 78 okay bye
Duh.
Why are they hating on scuba divers so much? He thinks he can study wildlife on one breath? Very pompous to say. Free divers always hating on scuba lol they jealous cuz they cant afford the gear lmaooooo
little scuba diver is butthurt haha
I'm a freedivier and a scuba diver and I can tell you that my freediving gear is so much more expensive. Just my carbon longfins are worth a small fortune
Top 5 of shitty places to dive LOL. The med is an absolutely horrible diving destination, the worst place I have ever dived and I’ve been diving a lot of places. Probably Ireland or Scotland is worse, just haven’t and will never dive there. Go to the Red Sea if you want spectacular diving that is nearby - otherwise Mexico, Australia, Asia and many other places have spectacular diving
