CAVE DIVING TRAINING with CHRISTIAN HUEMER of AUSTRIA

During Monday, January 16th, 2012 I met Christian Huemer, Age 28, of Austria along with his beautiful girlfriend at their hotel they were staying in Playa Del Carmen.  I was picking them for their week's stay at my Condo building La Costa in Puerto Aventuras.  Christian was taking the complete cave diving training course.  I had a second student scheduled, but he had family problems occur the day before and had to drop out.  We stopped at the MAYA MALL for them to grocery shop at the Sorianna's Grocery store so that they had plenty of items to make their stay in the condo comfortable.  Later in the evening we reviewed all of Christian's paperwork and I presented the orientation of the course and materials for his training.

The next morning, Tuesday January 17th, we met at his condo and I presented about an hour of lecture material then we took his equipment up to Cenote Chac Mool at my bodega that I share with Natalie Gibb and Dennis Weeks.  We spent three hours reviewing the equipment configuration philosophies that take place in today's cave diving along with transforming all of his equipment into a complete Hogathian cave diver - meaning there are choices to consider that are practical and smart and not the military style of one way or no way gear configuration.  

We had lunch in the Puerto Aventuras marina at DOS CHILES Restaurant and then we went back to my Chac Mool bodega to get our equipment.  For our first dives we did open water skills such as laying a guideline, follow a guideline with eyes closed, share gas/touch-contact, reeling up a guideline along with a steady dose of gas/air valve shut downs with the double tank manifold, etc.   We performed a dive upstream and another dive downstream.   Christain was really good and his attitude was delightful as he learned everything quickly and performed his skills with precision.

During the course structure and performance, Christian performed a total of 22 cave dives totaling in 1232 minutes of bottom time.  Our dives included Cenote Chac Mool,  Cenote Dos Palmas, Cenote Taj Mahal, Cenote Zacil Ha (Carwash), Cenote Minotauro, Cenote Tux Kapaxa, Cenote Coop One, Cenote Calavera (Temple of Doom), Cenote Calimba (the Grand Cenote), Cenote Chan Hol, Cenote Dos Pisos and the Grand Cenote diving through the Cuzan Nah area and way beyond.  With his skills we practiced at least seven out-of-air/touch-contact scenarios, three lost line drills, 24 jumps or gaps, 14 permanent "T" intersections and 23 minor restrictions.  In addition, we performed air/gas valve shut down drills every dive, out-of-gas "S' drills every dive session and continuous, contant work on hovering, buoyancy control and swimming/finning techniques.

Cristian's attitude was excellent and understood the difference between Smart & Safe ...and...dumb and dead.  It was a great pleasure to dive with Christian.  I have no doubt that he and his girlfriend will return to the Riviera Maya for more adventures.

DPV CAVE DIVING WITH ALEX DUPONT of SAO PAULO, BRAZIL








During the week of January 1st, 2012, I had the great pleasure to teach the six day SUBMERGE DPV cave diving course for ALEX DUPONT of SAO PAULO, BRAZIL.  We began the training on Tuesday morning, January 3rd, 2012 with our first session at CENOTE MANATI at Tankah Beach located about 8 kilometers north of Tulum.  We performed skills with becoming familiar with the machines such as slowing down, banking, loop to loops, etc. while using one machine and than progressing with towing a second machine.
We performed a variety of emergency procedures such as sharing gas, towing a machine and diver and propeller failure.

The four hour session was very valuable to Alex as his confidence grew as his skills driving the machine while in an open water environment grew and grew.  The greatest aspect of CENOTE MANATI is this 300 meter spring "run" is identical to a large cave passage but has no top.  A perfect beginning in learning how to operate the SUBMERGE DPV in the "overhead" environment.

That afternoon we performed our first cave dive using the SUBMERGE DPVs at CENOTE CHAC MOOL traversing to CENOTE PASCAL 3300 feet upstream.  It is a 23 minute run to reach this cenote. My personal "best" time is 19 minutes.

On Wednesday, January 3rd, we performed DPV dives at CENOTE DOS PALMAS of SISTEMA DOS OJOS.  We were able to get almost 2500 feet upstream from the west cenote of DOS OJOS.  Our Wednesday afternoon was at SISTEMA TAJ MAHAL diving to CENOTE BUENA VISTA and then we took the machines to "THE CITY of AGRE"  Room and beyond.  On our exit portion of these dives we practiced the "out-of-gas" share-gas drills while running the machines along with "towing" procedures.

On Thursday, January 4th, 2012 we dived at CENOTE JAILHOUSE driving our machines downstream into the massive saltwater passages.  That afternoon dive was at CENOTE CHICKIN HA diving downstream from CENOTE X'TABAY and making it to "THE CHAPEL" Room of SISTEMA PONDEROSA and back. 

On Friday, January 5th we added a second DPV to be towed and carried two stage bottles as our main gas supply with our double tanks on our backs to be used only in an emergency.   We entered at CENOTE DOS PALMAS and made it to almost the far end of the LSD AREA of SISTEMA DOS OJOS.  We calculated we got close to 13,000 feet from CENOTE DOS PALMAS.

On Saturday, January 6th we dived at CENOTE WHITE RIVER, which is now part of SISTEMA SAC AKTUN.  We made it, as planned, to CENOTE PACKAL.   For a short second dive we motored downstream to visit an ancient Mayan pot and a large animal skeleton.  On the return, we practiced sharing gas while running the machines in open large areas of the cave.

For our GRADUATION DIVE on Sunday, January 7th we entered at CENOTE DOS OJOS EAST, practiced all of our pre-dive rituals and then we motored to CENOTE  TIKIM ICH where we dropped our first stage bottle and our first DPV machine.  From that cenote we motored with our second machine and second stage bottle to within 600 feet/90 meters of "THE PIT".  We swam the distance and Alex was in "AWE" of the exit view. My only complaint was the EJIDO JACINTO PAT has now extended the roadway all the way to "THE PIT" and eliminated the 125 meter hike thus making THE PIT easier in accessibility.   Personally, I think that is great but I questioned whether this will make the odds of a deep water fatality more accessible.  Who knows?   What is....is what is!   While we were doing our SAFETY STOP we watched a three person side mount cave course begin their dive along with two cavern tour dive groups of two person teams exit the cenote using the "rope system" with a new wood platform constructed bridging the cenote land gap on the southern end of the cenote.
Our exit portion of this three hour dive went flawless as everything I planned out prior to the dive was religously followed by Alex, as expected, as we had NO problems and pure fun enjoying these SUBMERGE machinces tow us back to CENOTE DOS OJOS EAST.

In review, I was impressed with Alex and his abilities to safely navigate the machines the nearly 10,000 feet distance to "THE PIT" and return.   He graduated from the six day training with a new vision of equipment configuration and the SAFE use of the SUBMERGE DPV machines.

New Cave May Yield Secret Passage

Sun Herald

Sunday June 25, 2006

Frank Walker

JENOLAN Caves last week grudgingly yielded up a 350 million-year-old secret when Sydney adventurers discovered a new cave that could be the missing link in a complex underground river system.
A joint team from the Illawarra and Sydney University speleological societies broke through a previously blocked underwater tunnel to emerge into a cave no human had ever seen before. It was the first cave found in the underground network in 42 years.
The first through was diver Michael Collins. "It was awesome to emerge into a space no living being had ever seen before," he said.
The explorers had pushed further than anyone before along the southern extent of the caves.
They headed downriver from Barralong Cave, diving through sumps - parts of the cave that were underwater.
The team came to a narrow passage that had been blocked by boulders. An earlier team had cleared the rocks but had to stop because the water had turned into a virtual mud custard.
This time the water was clearer and Collins and Jason Cockayne spent two hours underwater trying to probe through the passage.
"It was like being the first man on the moon - no footprints, no sign of anyone ever being there before," Cockayne said.
As the first man into the cave Collins had the right to name it and decided to call it Captain Cook's Cavern.
The divers risked being buried in sand as they dug shifting sand, mud and boulders to clear a passage wide enough to drag themselves through.
They finally emerged into the cave, 10 metres high and three to four metres wide, which could be up to 100 metres long. Walking along the cave, they hit a rockfall.
"There are a lot of rocks that have fallen from the roof and it is hard going but we think the passage goes on further. We have to go back to try again," Collins said. "It gives such a feeling of pride and achievement to make a breakthrough like this."
Team leader Keir Vaughan-Taylor said it was a major discovery.
"Cavers have been searching for generations trying to find this missing link in the underground river system," he said. "The new cave contains sparkling chocolate-coloured flowstone due to unusual mineralisation."
There are 22 caves in the Jenolan system. The first to be discovered was Lucas Cave in 1860.

JENOLAN'S MISSING LINK

The 100-metre long cave could be the missing link in the two kilometre long Jenolan
underground river system.
Bizarre crystal growths, helictites, are gnarled fingers of stone made from calcite crystals growing along a tube formed by a slow leak of water.

Trapped cave diver died doing what she loved most

The Age

Tuesday March 1, 2011

By FARAH FAROUQUE. With MEGAN LEVY

HER delight on embarking on yet another cave-diving adventure is captured on the social networking site Twitter. ". . . fabulous! Can't wait to get underground," Agnes Milowka declared on Friday.On Sunday, however, something went awry for the accomplished Melbourne-based diver as she went exploring at Tank Cave, a seven-kilometre maze of passageways near Mount Gambier in South Australia. Worried members of her diving party reported her missing to police at 1.45pm.Her body ��� trapped about 600 metres from the entrance of the subterranean cave system��� has since been found, but retrieval remains hazardous and may take as long as five days, SA police said yesterday. The police are being helped in the operation by members of the Cave Divers Association of Australia.Ms Milowka had ventured into Tank Cave before, describing it as "a spiderweb gone wild" and "a joy to dive". Superintendent Trevor Twilley said police would not be able to determine what went wrong until they recovered and tested Ms Milowka's equipment. There are reports that she separated from her diving buddy before she disappeared in deep water.Ms Milowka, 29, who had worked as a stunt diver on James Cameron's 3D diving film Sanctum, was aware of the risks she took as a cave diver, an activity well deserving the epithet "extreme sport".No more than 1000 Australians are believed to actively engage in the pursuit at any one time. Adventurer Jacques Cousteau was among the pioneers of the modern sport.Ms Milowka began cave diving in 2005 and had completed more than 500 dives when she died. On her personal website, which is emblazoned with the motto "PASSION . . . DARING . . . ADVENTURE", she revealed that diving generally had been "at the very centre of my existence" since 2002."You dive often enough and for long enough, and you will find that the age-old saying 'Whatever can go wrong will go wrong' is not a cliche but a hard and fast reality," she blogged last year in a prescient post titled, "When things go wrong underwater.""People often freak out when I start talking about cave diving and they assume that the most dangerous and scariest moments I've experienced underwater have been in caves. In fact, my scariest in-water moment was not inside a cave system but in open water . . ."Stephen Newton, principal at Caulfield Grammar where she attended high school, yesterday described Ms Milowka as a "wonderful contributor" who had excelled in sport and studies. She was a house captain, champion school rower and was a finalist in the statewide VCE achiever award.Her website says she holds the current penetration record for a woman diving in Australia, and had dived extensively in Florida in the US.In March last year, in another cave diving misadventure, Melbourne doctor Robert McAlister died in a sinkhole at Mount Schank near Mount Gambier.

Body of missing cave diver found in Co Galway

Updated: 10:49, Wednesday, 7 September 2011
The body of a cave diver who went missing in an underwater cave in Co Galway has been found this evening.

1 of 1Alarm was raised yesterday
Alarm was raised yesterday
The body of a cave diver who went missing in an underwater cave in Co Galway has been found.
Artur Kozlowski, a Polish man in his 30s, failed to resurface after diving in caves near Kiltartan, north of Gort.
A spokesperson for the Irish Cave Rescue Organisation said that Mr Kozlowski's body was located and secured at the known limit of the cave, at a distance of 850 metres from the entrance and at a depth underwater of 52 metres.
Mr Kozlowski was an experienced diver. It is understood he went diving in the Pollonora cave at 3pm yesterday afternoon and had enough oxygen to last until 9.30pm last night.
The search began when he did not resurface and another experienced diver went into the caves at 11pm.

Cave Diving is Insane

By Rocky Thompson on May 6th, 2011

A cave diver on an expedition supported by National Geographic set a record depth of 636 feet while in pursuit of exploration of a cave in New Zealand. He realized his breathing had become erratic at the great depth and began slowly creeping back to the surface. Cave divers are insane. Say what you want about wingsuit flying or being a bike messenger in New York, this is the most dangerous thing in the world - it’s not like you can just hold your breath and swim to the surface when things go wrong. Much of this particular cave is still unexplored. I hate to say it, but why don’t they just use a tiny unmanned submarine

The Golden Rule of Diving

By , About.com Guide July 6, 2011

I was guiding a cave dive in Chan Hol Cenote when one of the divers signaled rapidly with his light - emergency! What could be wrong? Before the dive we had completed the standard equipment check and had reviewed the dive plan thoroughly. The first ten minutes of the dive had been absolute bliss. We floated through snowy white passageways and happily pointed out intricate formations to each other. All appeared calm and under control until the diver gave me the emergency signal. Imagine my confusion when he held up his air gauge, which indicated a nearly full tank of air.

The Lost Art of the Controlled Descent

By , About.com Guide September 27, 2011

During the first day of the Intro to Cave Diving Course, my student dumped all the air from her buoyancy compensator and sank like a bowling ball in her double tanks. Kicking and flailing as she sank, she reminded me of the victim of a mob hit, weighted down and tossed overboard to swim with the fishes. She landed heavily on the loosely-packed bottom sediment, creating a mushroom cloud that quickly reduced the visibility to zero. (Skip ahead to learn 6 Steps to a Controlled Descent).

3D studio finishing cave diving, filming at Indian Ocean for latest movie


cave diving
3D Production company PassmoreLab has finished its filming for its latest science film “The Extreme Nature of Bats” after several months of filming at the Indian Ocean.
The film deals with the myths, truths and dark legends of bats. In order to make this possible, the crew went into a cave diving expedition to explore three bat species, the megabat, free-tailed bat and vampire bat.
Aside from their shoot at the Indian Ocean, the crew traveled to several parts of the world to film the bats in their natural habitats.
The production of the film started in October last year in Texas. The crew filmed the free-tailed bats at one of the state’s biggest caves. There are about 12 million Mexican free-tailed bats residing in the cave.
The crew then traveled to Romania to explore the myths of bats and the proceeded to Mexico to film the vampire bat and at the Indian Ocean for the megabat. Lets just hope the women wore sports bras on this epic adventure!!

Sanctum: Making the 3-D Cave Diving Adventure (Yes, a Gigantic Fish Tank Was Involved)

3-d-camera-film-sanctum--475 Photograph courtesy Universal Pictures

SANCTUM EXTREME ADVENTURE CONTEST: Share your best adventure story and photo for a chance to win great prizes! Find out more here.


Alister Grierson,
director of the new adventure film Sanctum, had never donned flippers and an oxygen tank before he signed on to join 3-D pioneers James Cameron and Andrew Wight's underwater thriller about a cave diving expedition gone wrong. The premise (which Wight describes in this interview): The world’s largest cave system is being mapped by divers when a tropical storm dislodges rocks that block the entrance. The team, which includes two tagalongs who are not experienced cave divers, is forced to find another way out, if they can survive. This study of human behavior under pressure is something that fascinates Greierson, who made his first film Kokoda about a WWII invasion in Australia, to great box office success. Here Grierson gives a fresh take on the submersive, high stakes world of cave diving and how they replicated it for the film (yes, a 130-foot fish tank was involved).—Mary Anne Potts
ADVENTURE: What did you know about cave diving before this movie came along?
Alister Grierson: Very little. It’s one of those sports you hear about, but usually you only when someone dies in a cave. Then you say to yourself, why the hell were they down there?
Tell us about going diving for the first time?
It was before pre-production had begun. We all agreed I needed to get into a cave to have the experience and translate that for the film. But I wasn’t a diver at all, so I had to learn to scuba dive. I did a two-day intense course with John Galvin, who wrote the screenplay. He’s a master diver and he taught all the actors to drive. On day three they put me in the cave in a place called Mount Gambier in South Australia.
It must have been shocking to go from learning to dive one day to dropping into a cave the next?
I have always been adventurous and keen to try new things. So I was willing. I was very confident that it would be safe, that they wouldn’t push me to do anything too risky. I mean cave diving is inherently risky, but I knew I had a good team to look after me. I picked up on the diving pretty quickly.
Take us through your first dive, as if we were actually there.
Every cave is different. The South Australian cave system is very unique; the area is dairy farming land. It’s like Swiss cheese under there. Cows are often found having fallen through.
There’s a big hole, like a man hole, that goes through the Earth like 20 meters. And you get out and you prepare and you put your wetsuit on. Experienced cave divers wear drysuits because it’s so cold. First you lower all your diving gear down through the well and into the water. They set up an A-frame and they lower you down into the manhole. That’s the most confronting bit. Then you break through then it’s like an underground lake, about the size of an Olympic swimming pool. It was big, very big. The roof of the cave is a couple meters above the water level.
Then you enter the water?
You get into the water, and it’s freezing cold and pitch black. So you turn your lights and go under. The first thing that hits you is the clarity of the water—it’s crystal clear. And that’s really quite stunning. It’s really a surreal environment. It’s pitch black and only your lights are guiding you. It’s kind of like you are diving a river. You are negotiating estuaries and tubes and trying to get a sense of the ancient space.
And it’s beautiful. And as Andrew Wight describes, you get a sense of flying. There’s no noise. When diving in the ocean, there’s not the ambient crackle sound. In a cave, the sound of your own breathing becomes hypnotic.
I was struggling just to learn how to dive, let alone really enjoying the moment. But I think I understand why these guys are driven to do this. It’s really interesting and different. The guys who really go hardcore, like the expedition leader in our film, want a great personal challenge.
So everything went smoothly on your first cave dive?
Well, I did have one panicked moment. We’d been gone for two days on our expedition. I was tired so I volunteered to be the first person to get out of the cave. The last thing we had to negotiate was this body tube, which was like 80 feet long. So I am squirming, worming through this thing, and suddenly I hit this wall of rock. There’s only one way out of here, and I think, Oh no, there’s been a cave collapse! Then I was really starting to panic. I thought, We’re screwed! But what happened is that there was this ledge and I went under it instead of over it. And so just for that brief moment I was totally in this headspace of being in a collapsed cave. So I kind of get it.
You experienced the basic premise of the movie—the terror of having the entrance blocked.
Yes. I’m not sure if I am ever going to be a cave diver. I like the idea of doing more diving, and looking at reefs, though.
As much as this film is about extreme adventure, there seems to be something universal in these relationships? I like doing stories about real people in real scenarios. Obviously this was a fictional event, but it examines people under pressure and how they respond. In these disaster-style movies, you try to find a hyper-realized version of life. You are sort of telescoping the life experience into 12 hours, or whatever it is, and so it becomes almost operatic in scope. Some people respond well in those crisis moments. Other people don’t.
Watching the characters evolve is fascinating, you practically forget about the whole 3-D aspect.
That’s our strategy and Jim’s [James Cameron’s] philosophy. First of all, it’s got to be a comfortable experience for the audience. Secondly, it’s about immersing them in the world of 3-D and getting hooked into the story. And the cave environment works really well for that.
Can you tell us about shooting on location compared to shooting in the 131-foot tank?
What we realized really quickly is shooting on location in caves is really hard. Obviously there are safety issues, but the logistics are really hard. Like water temperature, for example. Even in a drysuit, the longest you can stay in the water is really 90 minutes. So if you are lucky, you could shoot two blocks of 90 minutes a day to do it. And that’s just too restrictive on finishing a film.
So you built a set?
We rebuilt the cave in the tank, flooded it, built ceilings over, then shot it at night to replicate the feeling of complete darkness. And then we could heat the water, which is the biggest asset. We had people in the water for 12 hours a day.
We had to keep the water clean. That’s the other thing about caves, they silt up really quickly. You’ve just got millenia of dust that settles on everything. So as soon as you move it, it makes the visibility zero. So we would bring in our own silt so that we could filter it out and clean it as we needed to, depending on the shot.
And most important it was safe. We taught all our actors to dive using rebreathers. So for all intents and purposes they were cave diving. It was that much safer. We could control the environment that much better. We had safety divers always at an arm’s length.
These actors had pick up a lot of new skills. Diving, yes, but rappelling, rock climbing, BASE jumping?
They all went for it. When they read the script, then would have known that it would have a lot of work. They love learning that stuff, but also it’s a way into their character, it’s something they could grab on to. With Alice [Parkinson, who plays Victoria], she loved all the climbing stuff and the abseiling stuff it was a way for her to understand what her character was all about
But Rhys [Wakefield, who plays 17-year-old Josh] did all the hard work. He did the climbing, ropes, the leaping, and the underwater stuff. The final thing he does in the movie, with breathing the bubbles along the ceiling of the cave. He did that himself. He did a lot of training to do it. I tried it, too, and I gave up. It’s really quite serious because as soon as you go into it, your head fills with water, it goes right up your nose. It fills your ears, it’s really disorienting. Then you have to move along the surface of the roof. And you really have to breath that air. He was really impressive.

GARY WALTEN “DID IT RIGHT!”

By Steve Gerrard, Puerto Aventuras

It seems like every six years you get a few folks who want to change things for the better. I have been reading with interest the comments made by various people about changing the cavern tour line at Cenote Taj Mahal (Maha) by removing the three permanent “T” intersections that have existed since its inception. First, I wish to make it clear that I agree that there should be no permanent “T’ intersections for a cavern diving “”tour” line as it is considered complicated. One continuous single line is the simplest and safest manner to follow. However, mother nature presents situations that we, as people, need to adapt to make things work in the safest and best way.

Gary Walten of Akumal served as the National Association for Cave Diving (NACD) Safety Officer during the early and mid 1990’s and installed the current cavern tour line that exists in this popular dive site. As with every cenote, each one presents unique physical characteristics that challenges the rules we establish as a Safe diving community. The rules we accepted are the following:

1. Natural daylight.

2. No Decompression.

3. No restrictions.

4. Maximum depth: 100 feet/30 meters.

5. Linear distance: 200 feet/60 meters.

The cavern zone of Cenote Taj Mahal (Maha) was first explored during the winter of 1995 by Nancy DeRosa and her brother Wayne Nefzger. The first “official” cavern tour was performed that spring with Beth Exley (Sheck Exley’s younger sister) and Mary Ellen Eckoff (Sheck’s former wife and best friend) and me as the cavern tour guide. What made the dive rather unique was an avalanche of percolation that we created near the area known at Bil’s Hole. Since then I would say that a minimum 40,000+ divers during 17 years have participated enjoying this cavern tour dive. There has never been an accident though I would not be surprised that there have been many incidents.

The cavern zone is basically shaped as an oblong hour glass configuration. You begin the dive from Cenote Taj Mahal (Maha) and enter a huge room with a large air dome named the “Points of Light”. The natural light is provided by three holes in the ceiling and the entranceway. On cloudy days you have basically no light from the two smaller holes in the ceiling. The dive continues with a traverse to a second cenote known as Cenote Sugar Bowl at a depth of 12 feet/4 meters. It just makes it with within the established rule of 200 feet/60 meters linear distance. The dive continues back down a steep slope staying within the established rules with two more openings to natural daylight (Bil’s Hole and a unnamed smaller hole into Cenote Esmeralda) forming a loop back to Cenote Sugar Bowl. To make this cavern tour dive enjoyable and be able to view everything safely he had to create three permanent “T” intersections. Two of them in the “Points of Light” room and one in open water at Cenote Sugar Bowl. Despite the established rules for safe cavern tours, Gary created the three permanent “T” intersections so that everyone could safely view and enjoy this unique cavern dive zone. As a reminder, two of the three “permanent “T” intersections are located in “open water”.

Please view the map:



As you can view the map of this unique configuration I cannot see a better way to place the permanent guidelines for this cavern dive. Despite all the good intentions to make this dive safer and better, I strongly suggest to leave it as it is as Gary Walten “DID IT RIGHT”.

Exploring the Secrets Underwater Caves through the Eyes of Expert Cave Diver

Posted: Mar 19, 2011 |Comments: 0 |
Not all of us can that easily take onto cave diving. It is limited to the adventurous and the brave because it is considered on of the most dangerous sport. Because of the risks involved and the fear factors, most of us do not get to explore the mysteries of the under water caves and the hidden beauty of these caves. One needs to be well trained to before he or she can delve deep into the dark underwater caves. One cannot expect to become a cave diver with their experience of their vacation snorkeling.

Cave diving requires you to be licensed before you can dive into an underwater cave. You can get these licenses from approved cave diving associations before you can take your plunge. Before certifying you and giving you the required license, cave diving associations will train you in cave diving safety measures and in basics of cave diving. As a cave diver, you will be using a number of gadgets and you need to learn how to handle them. Cave diving courses will train you in these as well. Though cave diving is very exciting, not all of us are ready to take the risks or spend time and money involved in training themselves.

If you think that you are missing out a great deal because of all the hassles involved, don't worry, you can explore the secrets of under water caves through the eyes of expert cave divers in the form of cave diving video or cave diving film. These videos are films are shot by fixing underwater cameras on to the expert cave divers and you get to see all that they see through the camera though without having to go through all the complications. A well-shot cave diving video can take you close to real under water cave diving experience. Such videos will ensure that you do not miss such tranquil beauty only few are lucky enough to see. You do not have to subject yourself through hours of training to enjoy the beauty of the underwater caves anymore. You do not have to spend hundreds of dollars to explore the underwater caves.

Underwater cave diving video will not only help those who cannot take the risks involved but a cave diving film that follows the trails of an expert diver can also serve as an useful resource for amateur cave divers and beginners. They will be able to learn more about the dangers of underwater cave diving and about handling difficult situations that shroud underwater cave diving.

You just need to spend a meager amount of money to acquire this precious resource. All that you need to make sure is that you find a cave diving video of a top expert in this field so that you ca n get the best of the cave diving film that you buy. You can find one of the best cave diving video of this decade at Acavediverstory.com.

Roman Statues Found in Blue Grotto Cave

Italy's famed Blue Grotto sea cave was once decorated by Roman statues of sea gods, surveys reveal.


By Rossella Lorenzi Mon Sep 28, 2009 05:15 AM ET

blue grotto statue Dating to the 1st century A.D., Italy's Blue Grotto cave was used as a swimming pool by the Emperor Tiberius (42 B.C. - 37 A.D.), and newly found statues there depict sea gods. This statue is the Greek god Triton.
Vasco Fronzoni |
A number of ancient Roman statues might lie beneath the turquoise waters of the Blue Grotto on the island of Capri in southern Italy, according to an underwater survey of the sea cave.
Dating to the 1st century A.D., the cave was used as a swimming pool by the Emperor Tiberius (42 B.C. - 37 A.D.), and the statues are probably depictions of sea gods.
"A preliminary underwater investigation has revealed several statue bases which might possibly hint to sculptures lying nearby," Rosalba Giugni, president of the environmentalist association, Marevivo, told Discovery News.
Carried out in collaboration with the archaeological superintendency of Pompeii, the Marevivo project aims at returning the Blue Grotto to its ancient glory by placing identical copies of Tiberius' statues where they originally stood.
Celebrated for the almost phosphorescent blue tones of the water and the mysterious silvery light flowing through fissures in the rocks, the Grotta Azzurra, as the cave is called in Italian, is one of the top attractions in Capri.
The island was the capital of the Roman empire between 27 and 37 A. D., when Tiberius made a permanent home there to take advantage of the mild climate and its seclusion.
Dividing his time among 12 villas and orgiastic feasts, the emperor used to bath in the almost hallucinogenic blue light of the cave, swimming among naked boys and girls.
The story goes that those who displeased him were thrown into the sea from a rock near his Villa Jovis. Perched 1,000 feet above the sea with Mount Vesuvius's cone in the distance, this was the most magnificent of his residences on the island.
The Blue Grotto might have been equally amazing. In 1964, archaeologists recovered three statues from the sea bottom. One sculpture depicts the sea good Neptune, while the other two statues each represented the Greek god Triton, who was the son of Poseidon (Neptune, for the Romans).
According to the archaeologists, the position of the Tritons' shoulders (the arms are missing) would suggest that the marine creatures were blowing into large seashells as if they were trumpets.
Triton was known to carry a twisted conch shell, on which he blew to calm or raise the waves.
The recovered sculptures confirmed an account by Roman scholar Pliny the Elder (23 A.D. - 79 A.D.), who described the sea cave as populated by a Triton "playing on a shell."
Now on display at a museum in Anacapri, the three statues have provided a glimpse of the original setting of the Blue Grotto.
According to the reconstruction, a swarm of Tritons headed by Neptune might have lined the rocky walls of the cave. Bathed in the magic light of the grotto, the statues stood with waters at their knees.
During the Marevivo survey, aimed at finding the original bases of the three statues, divers found a total of seven bases at a depth of 150 meters (492 feet). This suggests that at least four other statues lie on the cave's sandy bottom.
"The sculptures were all placed at the same level. It is likely that other statues will come to light as the project continues with new underwater investigations," diver Vasco Fronzoni told Discovery News.
The Grotta Azzurra's reputation as a natural paradise was seriously threatened last month. The cave was closed twice due to fears that its waters had been contaminated by raw sewage.
Aimed at returning the grotto to its full ancient glory, the Marevivo project is also expected to pave the way to a more strict controls to preserve the natural wonder.
"By next summer, tourists to the Grotta Azzurra will enjoy a really unique experience," Giugni said.

Man rescued from cave shares his story

Posted: Jun 20, 2011 4:37 PM Updated: Jul 18, 2011 6:12 PM

HUNTSVILE, AL (WAFF) -
An experienced cave diver is recovering after spending 30 hours in a cave last month.
In May, 52-year-old Dirk Siron was pulled to safety after he fell about 25 feet in a Southern Tennessee cave.
Dozens of rescue crews rushed to save his life. Siron said it happened so fast.
"I just remember falling and then seeing blackness," he said.
The fall inside Sinking Cove Cave left Siron with broken bones and a story to tell. A caver for 16 years, Siron has scaled hundreds of high places and crawled his way through low ones including the cave that almost took his life.
"I've done that cave more times than I could count," said Siron.
But it took one more time and one false move to turn a routine caving trip into a major rescue operation in May. On the way out of the cave, Siron was latching equipment when, as he said, "without looking, I apparently pulled the wrong end of the rope."
He fell 25 feet-it was like falling from a two story house.
"When I fell I was upset with myself mainly because I knew that I was hurt and that there were going to be a lot of people coming and I didn't want any of them to get hurt," said Siron.
The same thrills that draw people to the cave-seven drops, tight crevices, twists and turns-are the same reason why it was a challenge for rescuers to pull him out.
After 30 hours with dozens helping, Siron was safely carried to a waiting helicopter. After that entire ordeal, Siron said he wants to get back to caving as soon as possible.

On March 13 the Southern Florida chapter of The Explorers Club will hold its next monthly meeting in Fort Lauderdale. Chapter members Casey McKinlay and Jarrod Jablonski will give a presentation titled “Exploring the Flooded Cave Systems of San Men Hai, Guangxi Province, China.”
At the invitation of the Chinese Government, the multinational Global Underwater Explorers team recently completed its fourth expedition to the remote karst region of south-central China. The GUE team included Jablonski and McKinlay plus Australia chapter member Steve Trewavas.
According to an e-mail from chapter secretary Beth Jones, “Their mission was to explore, map and unlock the underwater mysteries of San Men Hai, which is located within the massive Fengshan Karst National Geopark.”
“The mysterious underwater rivers, world-renowned dry caves and breathtaking pinnacle karst landscape presented formidable logistical challenges for the GUE team as they worked to physically connect the massive, flooded underwater cave systems, map the flooded chambers and gather water-quality and water-flow data in an effort to support the Chinese government’s pursuit of UNESCO World Heritage site designation in addition to baseline measurements necessary for future protection of these unique and vulnerable natural resources.”
The Explorers Club, founded in 1904, is an international multidisciplinary professional society dedicated to the advancement of field research and the ideal that it is vital to preserve the instinct to explore. Since its inception the club, which is headquartered in New York, has served as a meeting point and unifying force for explorers and scientists worldwide. The club’s members have been responsible for an illustrious series of famous firsts, such as first to the North Pole, first to the South Pole, first to the summit of Mount Everest, first to the deepest point in the ocean, first to the moon.
To RSVP for the March event at Tropical Acres Steakhouse, e-mail Beth Jones. The cost is $32. A cash bar opens at 5:30 p.m. and dinner is served at 6:30 p.m. with the lecture to follow

HISTORY OF THE LINE ARROW

History of the line arrow
« Thread Started on May 22, 2009, 5:12am »


"THIS WAY OUT" is the message a directional marker conveys. Dry cavers were using directional markers in the maze of tunnels that constitutes a cave system long before there were cave divers. Being lost in any cave is a terrifying experience but being lost in a water-filled cave with a limited air supply is very likely a fatal error. "This Way Out" must be unambiguous to the extensively trained cave diver attempting to feel his way to the exit in a severe silt-out situation.

There are several basic rules that are necessary for a safe cave dive. One of the most important of these rules is that there must be a continuous guideline to the surface. Silt (unconsolidated sediment) is found in all underwater caves. When suspended in water, silt may reduce the visibility to effectively zero in a matter of seconds and may persist for several hours or days. Common causes of silting are the downward-percolation of ceiling silt caused by the diver’s exhaust bubbles; water turbulence by diver movements; and, wash-down caused by heavy local rainstorms.

The early cave divers in Florida saw the benefit of using directional markers on the guideline. Lewis Holtzendorff came up with the idea of folding a triangle of tape around the line to form an arrow that would point the way out of the cave. These tape arrows were called "Dorff" markers in Lewis’ honor. There were a couple of problems with tape arrows: they slid along the line and they were difficult to feel in a silt-out. What was needed was a standard arrow that was simple, inexpensive, and easy to attach to the line but resistant to being dislodged.

Sheck Exley asked Forrest to lead a discussion group at a National Speleological Society-Cave Diving Section (NSS-CDS) workshop to come up with an idea for a better arrow. Several ideas were tossed around, but most were deemed impractical, including one that was close to today’s line arrow. After the meeting, Roger Werner had drawn an idea for arrows on the blackboard, but Forrest felt it would not stay on the line because the slots Roger drew were straight out to the sides.

Reflecting upon Roger’s idea, Forrest made some prototypes and tried them in caves. After several combinations of slot angle and relative hole shapes, he eventually formulated the current design. He hand-made several hundred arrows that were sold through the Branford Dive Center in the scuba gear section. The arrows soon became very popular and Steve Hudson of the cave rope company, PMI, asked Forrest’s permission to make a mold of one of the hand-made arrows in order to mass-produce them.

In the mid-1980’s, Forrest Wilson stopped designing cave diving equipment and gave permission for anyone to copy his designs. Cave diving equipment manufacturer, Dive Rite, bought the entire production run of the PMI line arrows. A few years later, Dive Rite tried to order more arrows, but to their dismay found that the injection-molding house had sold the original mold as scrap. They successfully tracked down the buyer and had more arrows made.
Dive Rite eventually bought the mold only to find that it was worn out. In 1993, Dive Rite produced a new line arrow mold, which is now kept in an injection-molding house in Jacksonville, Fl.
Today many companies around the world manufacture "Line Arrows". They have become a tool used not only for cave diving but for wreck diving as well.

It is Mr. Wilson’s line arrow design that is used universally today.

Warning: Cave diving is a hazardous activity that may be undertaken with relative safety only with specialized cave diving training, specialized equipment, and skill performance. Please seek out an accredited and qualified cave diving educator before considering engaging in this activity.
Cave Diving in France: Tea and Medals

The Dordogne/Lot area is one of the greatest cave diving areas in the world. The three rivers, Dordogne, Lot and Céle in the central, southern region of France offer over a dozen classic cave dives including some of the longest and deepest "siphons" in the country, if not Europe: Emergence du Russel; La Doux de Coly; Trou Madam; Gouffre de Cabouy; Gouffre de St Sauveur; Fontain de St George; Oeil de la Doue are some of the evocative names given to these sites that are peppered throughout the region.

These dive sites however, are not the squalid, claustrophobic "grimness" or "misery" that is often UK cave diving; here there are big, 'friendly', clear-water passages; a different philosophy. "If you can't get twin 15s and a 'Zepp' down then it is, by definition, too tight" my diving companion Andy declares. Summer water conditions in the caves are a comfortable 15 degrees centigrade and vis can be gin-clear, especially around the end of August/ September. Rainfall in the summer is often infrequent and patchy, affecting certain caves with a little milkyness only if rain falls within the catchment area. Many sumps here have navigation lines for 100s of metres and can be accessed almost from the roadside. Summer air temperatures can be in the 30s: perfect for the après-dive "tea and medals" on the terrace of a local cafe.

The Dordogne region has been at the forefront of European cave diving developments and exploration for decades. The depths of Emergence du Russel, for example, were plumbed in the seventies to more than 70m. Toe-curling epic dives have been executed using innovations such as half a dozen 'jumbo rigged' 20 litre cylinders, twin re-breather gear and doubled-up underwater scooters. People have successfully penetrated thousands of metres into these systems, reaching amazing depths of 80 m during dives that have lasted several hours. Some of these adventures are testament to the teamwork of dedicated diving groups whilst others are the achievements of rugged individuals. Martyn Farr's book The Darkness Beckons describes some of the classic milestones achieved by these legends.

The Dordogne has become popular with British tourists and many have bought homes here. In some parts, entirely British communities have developed and there is at least one with an English Mayor: this is somewhat ironic given that this was a part of France that was hard fought over by the French and English in the Hundred Year's War!

Oak woodlands upholster hillsides, often 'reserve de chase' (for hunting), and ubiquitous pale limestone cliffs climb out of deep-cut river valleys. There are plenty of opportunities for the outdoor enthusiast as well as the cave diving. Climbing, dry caving, show caves, canoeing cycling and canyoning are all possible if you are overwhelmed by the logistics (and "kit-fettling") associated with cave diving or just want a bit of variety. There are plenty of information leaflets available for any of the many companies offering these outdoor activities. There are dozens of castles in this area too, as well as the Roman bridge at Cahors and some of the worlds best prehistoric cave paintings.

Europeans from all over have been making regular diving trips here since the 1960s but in recent years some sumps have been 'closed' to divers. In this quiet rural setting cave diving is approaching crisis; teetering on the edge of acceptability. There are often rumours such as that of a Swiss diver being arrested and having all his equipment confiscated for diving at the Saint Saveur site but in several years of diving this area the group I was with had never come across anyone with any first hand experience of access problems. Nevertheless, the Mayor of Marcilihac, the nearest town with jurisdiction over the Le Russel site, confirmed that there is pressure to close the sites. Elsewhere, where there have been rescues in the Dordogne region the local inhabitants end-up footing the bill for police and fire brigade services and in a rural village of 300 people they feel the sting in tax. The other major problem for the future of top dive sites such as Le Russel is that there are plans to extract drinking water (eau potable). This gives Le Russel only a couple of years until it will be closed-off to the diving fraternity.



A Selection of the Dives


Emergence du Russel

Photo copyright Bill Sanderson/Aquaticus Emergence du Russel is a large impressive cave that starts in the bed of the River Céle as a clean washed passage of about 150 metres in length and with a cross-section at least the size of a double garage door. It then splits into two passages: one tunnel stays shallower at about 10 m depth whilst the other runs broadly in the same direction dropping repeatedly until it reaches around 18m. The two passages rejoin (making a nice round-trip for those new to cave diving) and, 300 m from the entrance, the cave takes the first of two dramatic plunges, eventually descending in a spectacular cavernous rift to about 45 m. To swim this far takes a round-trip of getting-on for an hour but for the members of the church of scootering in our party, emblazoned with the words "Forgive me father for I have finned", this is a trifling undertaking. From this point the entrance is getting towards half a kilometre away and the dive is increasingly technical, descending first to about 50 odd metres fairly soon, then, after some time to as much as 77 m before beginning to ascend and eventually entering into another rift that towers to a dry section of cave nearly two kilometres from the start. The whole trip through is a serious expedition of several hours and has been made by only a handful of people ever. In the last year sumps beyond this, running to more than 4 km in total, have been pushed by British divers Rick Stanton and Jason Mallinson.

Trou Madame

Trou Madame is a short walk down a track following a dry tributary river of the Lot to a large cave entrance. This popular cave narrows-down to an entrance pool where you need to stoop. The whole cave system is a series of multiple sumps of varying length, all quite shallow at less than 15m depth and often with overhead pockets of airspace making an excellent training site. This system was explored as early as 1979 to nearly 2.5 km. The scalloped and knarled rock formations make it a favourite for photographers.

Fontain de St George

Fontain de St George is where some of the first penetrative cave dives were achieved in France. It is in the Dordogne Valley, near to Montvalent. The sump pool is large and picturesque, some 30m in diameter, and only a short distance from the car. The cave starts in the bottom of the resurgence pool at about 10m depth and descends at a steep 45 degree angle over a cobble and gravel slope with a low ceiling that hangs-down in a series of ridges giving the impression of gummy, mouth-like gaps. This passage can be a little awkward at times averaging about 2 metres high by 5 m wide but once you escape from it at near to 30 m depth, the passages are wide and open, even cavernous at times. Parts of this sump can be a bit gloomy on account of banks of silt but it gets gradually shallower before surfacing after a third of a kilometre in a chamber called Salle de Lavaur. The second sump passage is spacious and continues for another third of a kilometre before getting complicated by descending to more than 70m then surfacing into dry passage at over a kilometre from the start. Beyond this are more explored sumps that have taken teams of thirty people to push. After several kilometres the waters flowing through the system are known to connect with the show cave 'Gouffre de Padirac': a substantial challenge!



Further information


Serie Bleue maps (1cm to 250m) are useful because many of the sumps are marked on them.

Andrew Ward's (1997) book Underwater guide to the Lot & Dordogne, France (Aven International Publications, Swindon, SN2 2AZ; e-mail: icaver@aol.com; £7 plus Post and Packaging) provides information on the "general idea of the sumps - number, length, maximum depth etc." but by his own admissions has focused on the larger sites with good access and large underwater passages and makes no attempt to give a blow by blow account of "every rock and twist and turn".
Read the interview Andrew Ward gave to SCUBA Travel...

The Darkness Beckons by Martyn Farr superbly encapsulates the history of the great diving advances in the caves of the region and has, this year, entered its third edition. Diadem Books; ISBN 0-906371-87-2. Available from Amazon.com and Amazon.co.uk (30% off).

Guidebooks such as the Rough Guide can be quite useful for those intending to explore more than just the caves. They can also give a handle on accommodation but most good travel agents can easily provide a wide range too.
The Rough Guide to Dordogne & The Lot is available from Amazon.co.uk (20% off) and Amazon.com.

There are several easy to find companies offering canoeing and other activities. We used Kalapca (kalapca@wanadoo.fr; Tel 05 65 30 23 33) on our last trip - based in the Lot valley just down the road from Le Russel.

Deep Blue Diving offer IANTD courses in cave diving, mixed gas and rebreather diving. They run regular trips to the Dordogne region and can be contacted at Deep Blue Diving, Unit 4 Thomas Street, Congleton, Cheshire, CW12 1QU, UK 01260 297998 www.deepblu.co.uk

The Cave Dive Group web-site is another useful point of reference: www.cavedivinggroup.org.uk
Marine Monitoring Team Leader, Dr Bill Sanderson learnt cave diving in the caves and mines of south Wales in the late 1980's. Now more normally accustomed to marine biological monitoring work in the seas around Wales, he accompanied some old cave diving friends on a holiday in France. He is also the author of Dive Sites and Marine Life of the Isle of Man - our September Book of the Month. For more about Dr Sanderson read our exclusive interview.
