The monster net
“Oh Hello, this is the Guardian. Do you have a moment?”
I was only a few slurps into my morning coffee and my breakfast was about to go cold.
“Sure, how can I help?”
Volunteering for the charity Ghost Fishing UK always threatened to take over our lives and we can safely say it has done just that.
Chair Richard Walker, myself and third trustee and operations officer Fred Nunn, a long-standing friend of about 8 years, all work pretty much full time in addition to our real full time jobs to run this world leading charity.
We have the largest group of Ghost Fishing trained divers in the world, with 70 on our books and 120 on our waiting list. This is in addition to a large pool of surface volunteers who we can call on at any time for help.
It is an incredible achievement and now, as a completely independent charity we are free to do things our way - and the organisation has flourished.
When I first took a bunch of Bristol no.3 British Sub Aqua Club members on a group trip with my small business, WetWellies Caving - my first customers in fact when I started in 2012 - I had no idea it would lead to this!
Much of what we do is self-taught. The skillsets we have adopted over the 5 years of running Ghost Fishing UK have sent many of our brains bulging. Who knew we'd have to write KML files or navigate the .gov website minefields? Risk assessments, mission statements, method statements, articles, training courses, website...you name it!
Many of us are doing things we probably never would have done otherwise and it has been a true rollercoaster. Fred was terribly nervous in front of the camera - now he takes live BBC interviews in his stride.

I had no press training but found myself having to learn the tough way and absorbing any education around the subject that I could.
This was one such occasion. I had written a press release using a template and some excellent educational materials from Class:PR and it went crazy!
After the Guardian, we started to see that a lot of news outlets were picking up our story.
Scuba divers from Plymouth had reported a very long, lost gill net on the popular and very beautiful Hand Deeps reef.
With a few reports and details in hand, we were pretty sure we could find it and deployed two Ghost Fishing UK teams onto the water. We were treated to a nice big hard boat, Seeker from In Deep Dive Centre and a professional crew who are totally on board with the charity.
One team located it and began surveying it.
Luckily, I was in that team so set about the net with my camera, documenting the trapped life in it.

Spider crabs, lobsters, fish and even urchins had got tangled up in the unforgiving gill net which had been fishing around the clock, indiscriminately.
Once surveyed, the team returned with knives, lift bags, stage bottles for lifting gas and a plan.
The net came free from the reef relatively easily and with no damage to the environment.
Once back on board the boat, the 2 hour ‘crab picking’ began.
Each trapped animal was documented according to species and whether it was dead or alive.
Luckily the sun was shining and the In Deep crew waited patiently as we dealt with each animal.
Over 100 animals were trapped in the net and around 80% were still alive and returned to the sea.
The net was measured at over 200 metres long (Fred is very keen on measuring and weighing things accurately) but its owner, not surprisingly, could not be found.
I put my new-found press release writing skills to the test and with a good story to tell, kept my fingers crossed.
BBC Spotlight did two great pieces on the story and we were then contacted by ITV and Channel 4, all keen to come out and film with us in the future.
Our social media lady, Dolly, also set about Instagram and Twitter and the levels of engagement were phenomenal.
It was a huge boost to the team after several months of being unable to dive, never mind head out on a mission and it was fantastic to get this net out of the sea so efficiently after a long time off.

Happy Camping
Covid semi-lockdown
The UK is a bit of a madhouse at the moment, with people flocking to the coast trying to grab some rays.
We've decided to stay local to home in the Mendips and continue prepping the dive wagon for when things are less 'chaotic'.
I once passed comment on a friend's cave diving article about the use of caving lights beyond sumps (flooded passages) and I pointed out that the only real use for a Petzl Tikkina was to find your sleeping bag in a tent in the dark!
So that's what we use them for. Lightweight, using AAA batteries and easy to hang up in the dive wagon for when you need to rummage around in the dark.
Fernand Petzl was a caver and lived close to the Dent de Crolles mountain in the Chartreuse region of France. I've enjoyed phenomenal caving in this stunning region and Petzl, apart from record breaking cave exploration feats, began making caving equipment and then expanded into climbing and skiing gear.
It is one of the worlds most trusted and respected outdoor brands.
Don't forget your fire extinguisher!
Most fires in vehicles are electrical so powder extinguishers are most appropriate. Messy, yes, but they may well save your vehicle and everything in it.
Store it where it is easy to get to from the cab and familiarise yourself with the instructions.
The two camping items that folk seem to always forget are a sieve - and a can opener! Don't rely on ring pulls!
A small chopping board is always handy, kitchen scissors and a decent spatula and set of tongs are always handy.
Don't forget the wine bottle opener and a decent sharp chopping knife is important.
These collapsible washing up bowls are perfect for van camping and are super space savers.
Make sure you get ones with handles to make carrying them around a campsite easier.
I use a mini refillable washing up bottle and a good size ball of metal wire sponge for hard to clean pans.
Don't forget cloths and a tea towel.
In the last blog I showed you the new van curtains which are super cool. But I couldn't seem to find a way of blocking out the large rear window. I've found this blackout blind which can be easily cut to size and I have suckers which I can attach to the window as I don't fancy having velcro stickers over the rear door.
All you need now is a good book, some snuggly fleece throws, sleeping bags (or duvet, as you wish) and some pillows.
And some wine of course!
So far we've camped out on our driveway! Rules: Only allowed indoors for the toilet or more booze! The neighbours didn't bat an eyelid as they are equally as mad. We even brewed coffee and made bacon sandwiches much to the amusement of the morning dog walkers.
Soon I'll be looking at awnings, extensions and comfy ways to get changed in and out of caving and diving gear.
My good friends the Burkeys came up with this 'ingenious' idea for changing in blood curdling weather in the Yorkshire Dales.
Caving instructor and roving cave gear shop Starless River happened to be passing. Tony Seddon leaned out of the window and stated that he didn't know whether to be impressed - or appalled!
Once we are able to head out properly, we'll blog on our adventures, little trips away and much longer road trips with Agnetha.
Who knows when that will be.
But some day soon, I hope...
Abime de Mas Raynal
It occurred to me that I hadn't been to this wonderful cave since about 2003. I was very much looking forward to rigging it this time, rather than being pushed back behind 'some bloke' who always assumed that it was a man's job. Bollocks to that, I say.
Suntan rigging the Mas raynal super direct route on my 3rd ever SRT trip.
In 2002, on only my 3rd SRT trip, I went 'over the edge' and did the main hang or 'super direct' route which is 106 clean metres straight off a rusty iron bar in broad daylight on a single rope.
The only interruption is a re-belay some 30m from the crashing river below.
Abseiling the multi pitch route in the Mas Raynal
The water heads North West to Source du Sorgues and is typically blue and cold.
The multi-pitch route is friendlier and has some snaggy, slimy green slopes on route to the final hang.
It is partially P-hung and partially requires spits and hangers - so it's advisable to take some hangers.
Ashley, my CDG trainee, wanted to do the main hang on 8mm. He rigged it but only ascended it and used our ropes on the way down.

The cave is like Alum Pot on speed. I think it is a little bigger in dimensions but the main hang is about the same.
Sunlight pours down the main shaft and the chilly gloom of the massive side inlet makes for some great silhouette photos.

The church bar
January 2019
Cave & Wreck Night, Netherlands
We always love heading to the Netherlands for Cave & Wreck night.
This event has been running for many years and the venue has grown to now be hosted in a huge church, which is the only venue big enough to take the 400 divers who attend.
What's even more impressive is that behind the altar is a bar!
They don't muck about in the Netherlands!
I’ve spoken here several times and this time Rich Walker and I were a double act, giving a catch up on exploration in Izvor Licanke, Croatia.
Rich has always tried to get up in the pulpit to give his talks but always worried about going up in flames!
It is becoming a tradition to be fed some serious gourmet, multi course meal at JP Bresser’s boathouse and he always raises the bar to show off his culinary skills. Accompanied of course by some serious wine from the caving regions of France.
It’s great to catch up with the GUE gang who come here from all over Europe and listen to inspiring talks about diving projects all over the globe.
View from JP and Anne-Marie Bresser’s boathouse in Netherlands
From cave diving discoveries to wreck documentation, the evening is packed with updates on what the GUE community has achieved in the last 12 months.
The following day, slightly hungover, we were treated to a thai kick boxing session at JP’s local gym, Gym Suppan. I can honestly say it is the most fun I’ve had in ages!
February
The next month I went to give a talk on caving to Bradford on Avon scouts and was treated to a busy church hall full of enthusiastic children asking intelligent questions.
I love inspiring youth to give caving a go and hopefully they’ll be the next generation of cave explorers.
Bradford on Avon Scouts
In March I headed out to a small platform called the Saltire. I was covering their regular medic who had to go home, so bizarrely I was the only person on the helicopter! Apart from the pilot of course – and she was female too!
I’m not sure if women have ever outnumbered men on a North Sea helicopter but it was nice to think it could have been the first time or at least one of very few.
There was only 14 of us on board, basically keeping the place ticking over until the decommissioning process.
International Women’s Day was happening and I was asked by Women Fitness magazine to write an article. I was excited at the opportunity to write for a non-diving, non-caving audience and slightly embarrassed that I was not the typical skinny or athletic type that adorned the glossy pages.
Even as a jump jockey I was always strong and solid and never waif thin enough to maintain a career on the flat.
What the hell, I thought – and I got writing.
Recce Day
Tuesday and D-Day!
It was time to see what Oz and Joe had done with my line reel in the passage Rich and I found last year, and on Oz's advice, to check it really was still going before we threw a big team and trimix at it.
We were very lucky to have Jean Tarrit and Claudine from the CLPA come along to help us underground and they did a great job of getting everything down to the sump's edge in under an hour.
Jean and Claudie
Jarvist and Tim set off into the sump wearing equipment I am too young to have ever seen before....but it seemed to work as they crossed the sump, tidied the line so that it was tight and immaculate and they preserved the visibility well.
Rich and I were to follow about 30 minutes later to give them a chance to rig a ladder to make climbing out of sump 1 much easier and to place a few bolts for ropes and general helpful tatt.
They did a great job and Rich and I kitted up whilst Jean and Claudine went up the ropes to get warm and get lunch.
We crossed the sump easily and had the luxury of walking straight up the ladder fully kitted without breaking sweat and straight down into sump 2.
Chris on the exit of sump 1
We dived to the end of the line, surveying last years new passage again as we went and hit 30m depth and my line reel.
The line had been beautifully laid by Oz and Joe and the reel was well tied off at the end.
I shone my cave hunting torch down the ongoing passage and could see large cave ongoing for at least 20m. Satisfied, we cleaned up and left, very much looking forward to the return trip on Friday, to allow the viz to settle after a couple of days.
Someone else's job - isn't it?
Published 2020
When Justin Hofman showed the world an image of a seahorse clinging to a plastic cotton bud, the world went into denial.
Some people tried to make excuses. They tried to claim it was fake, photoshopped, not real, a lie, an exaggeration.
People didn't want to believe it.
But everyone knew it was real. So real in fact, he took lots of images that day. He simply selected the best one.
“It’s a photo that I wish didn’t exist..." he said. Who can blame him?
Last week, in October 2020, England announced a ban on plastic straws, stirrers and cotton buds.
But does it go far enough?
I organised my first beach clean in 2011 and was shocked that, even after a few hours, most people on the beach hadn't moved. There was so much plastic litter that it took us all day in the sweltering heat to remove it from 100 metres of beach.
When I set up my own business, WetWellies Caving, way back in 2012, I promised from the outset that my business would be as green and environmentally friendly as it could be.
We did all our bookings electronically or by phone - we never posted out paper or spammy leaflets. We re-used drinks pouches and reduce single use plastics as much as possible. We encouraged our cavers to pick up litter both underground and on the way to and from the caves.
But given that WetWellies pretty much worked from home, I thought I'd share with you a few things I do about the house to make a small difference.
I use biodegradeable cotton buds, recycled and plastic free loo roll from Who Gives a Crap and hair products from Soul and Soap.
I buy kitchen bin liners and compost bin liners from BigGreenSmile.com. These are completely compostable and strong enough to take our household waste and leftovers.
I recycle anything that the local council will take away and run anything else up to the local recycling depot. A handy kitchen basket acts as a collecting vessel before we sort it into the recycling buckets outside.
I have lots of re-usable 'bags for life' and try to avoid single use plastic bags.
I have re-fillable bottles of ecover washing up liquid and every couple of months I get re-fills at the local organic supermarket in Castle Cary.
Buying veg at the supermarket is almost impossible without bringing home single use plastic. I try to pick up unwrapped vegetables and this I made easier by using our farm shop 1 mile away, or even better the Friday veg Market in Shepton Mallet.. Tesco already got rid of their own brand of plastic cotton buds and replaced with paper.
Sadly, many types still come in single use plastic wrapping. Another example of a gesture that only goes half way.
A few years ago I was given 'The Self Sufficient-ish Bible' which is full of great ideas to try to do things in a better way for the environment without having to go to extremes. It offers realistic and achievable small changes for normal, busy people.
And finally, I compost any food scraps and offcuts which go into a fully compostable bag which we have trained the local recycling crew to take as well.
I sat down and worked out, roughly, how much single use plastic use I have used in my lifetime.
It is extremely difficult to work out, so I had a go at just working out, approximately, how many shampoo bottles I have got through as an adult.
I moved away from home and lived independently from the age of 16, so I thought I'd start there.
I have always had long hair and get through about one bottle of shampoo every 3 weeks. So:
I used about 17 shampoo bottles a year.
That's 408 single use bottles of shampoo since I was 16.
ONLY shampoo. You can double that figure for conditioner bottles.
Since 2018 I have been using shampoo and conditioner bars with no plastic packaging whatsoever. The downside is that they are more expensive and this is a problem. Single use plastic is cheap. Plastic free products have a low production volume, lower demand and thus, are dearer.
We need to make non plastic options affordable and even cheaper, before we can get everyone onboard with ditching single use plastic.
Now, I work offshore in the oil and gas industry - but before you shout 'hypocrite' from the rooftops, I should point out that I am a medic. Everyone needs a medic and, frankly, the oil and gas industry is not going to cease overnight just because Christine the medic chose a dfferent job.
I'm a Paramedic, actually and also an offshore diver medic. I look after divers in sat chambers and quite often their jobs are repairing leaks, investigating any break in containment and often making oil and gas rigs last longer so that the fulfill their worth before newer ones are built.
The vessel I work on has a very low carbon footprint and everything gets recycled. Nothing gets dumped in the sea - the fines are horrendous and the company looks bad. We even make water on board and there are recycling separation bins everywhere.
Working offshore does give me an insight into an industry not everyone has access to, plus it gave me enough spare time to support my voluntary work as trustee, secretary, photographer, instructor and general dogsbody for the ocean clean up charity, Ghost Fishing UK.
Even though my background is in medicine, I do enjoy learning about the oceans and educating myself more and more about the threats to our blue planet.
I've enjoyed some excellent (and mostly free) online learning to keep the grey matter ticking over.
Why not give it a go?

Caverns Measureless
A good day out…
We met up with Nathan as planned at 10am in the car park closest to the cave. He had brought a friend along to come and help, called Mario. Mario is 25, a new member of the CLPA and was clearly being given some sort of induction involving carrying diving gear half a kilometre in the heat – none of which was his!
Nathan explained that he was the first person to dive the first sump in this cave 15 years ago!
Passing dive grear through the entrance boulder choke - which is full of spiders…
We made it to the entrance with a bit of prickly bush bashing and a shin-bashing dry riverbed. Here, we gathered kit by the entrance and sent Nathan ahead to check that the boulder choke was safe (he was concerned that the winter floods might have caused it to move and become unstable). He called up that it was and we followed, ferrying ten 7 litre cylinders, 5 divers wetsuits, equipment and lead (top tip – unless you are all diving at once, share lead!!!!) fins etc and a bolting kit and rope, in case it was needed for the climb out of the water at the end of sump 1.
Rich and I were to dive first and see how far we could get. It is reported that the winter floods rip the line out of these sumps, so we had plenty of line ready to go in and loads of snoopy loops for belays, if required.

A line was tied off at dive base and water levels were extremely low. We passed all the equipment down the ropes and Rich and I kitted up in 7mm wetsuits and sidemount gear with a little buoyancy and set off into sump 1. This is 70 metres long and has a maximum depth of 21 metres. The sump was crystal clear with a blue tint as many of these Herault sumps have. Nathan followed five minutes behind with the bolting kit and rope.
The line was there…..but very slack and we took in metres and metres of loose line. It had been laid in zig zags across the passage and every belay except one had come free. We tied up the loose stuff as best we could and surfaced in a large air chamber with the reported climb in front of us. A thick rope was already in place, to our relief and we climbed up the rock face to land on a ledge above. We started down the jagged rock through some holes which led to the start of sump 2. Again the line was in place, but this time was much slacker and was combined with old, French washing line. I tried to tie some of it together in case the visibility was decreased on the way home
We flopped into sump 2 and very soon surfaced in a bit of an airbell with the continuation ahead. Annoyingly, this meant a brief excursion above water, crawling on hands and knees and falling face first into the water on the other side of a rock barrier. Rich dived in front and I couldn’t help but giggle through my regulator as I watched this GUE technical instructor, our lord and master, crawling on his hands and knees then wallowing unceremoniously, helmet and all into the water face first, fins waggling in the air. You had to be there……
Rich dived ahead with the line reel and, after a narrow rift, soon came across the end of the white French dive line. It was tied off to a rock spike pinnacle and the line was wrapped around it several times, almost in a statement. Here we go……
Rich tied my line reel into to line and began to pay out line into the rift ahead. It was a narrow, inclined 45 degree rift and I deployed my extreme-tek backup torch to spot the way on. This long, narrow beam hunted out a widening in the passage lower down whilst Rich searched for tie-offs as he went higher. He indicated to me to tie the line off as he went and two belays later, the viz started to go. Ten metres of progression and I could hear, but not see, Rich scrabbling and scraping ahead and not finding anything to tie the line to, he wriggled back towards me. I fended off waggling fins and coiled up loose line, whilst Rich began to reel back in towards me and gave me a thumbs up and ‘turn around’ signal. I pulled a snoopy off a rock and the rock simply broke in two and fell off the wall. The whole cave is made up of porous, fragile and friable rock which simply won’t tolerate interference.
We dived back on thirds and I kicked on ahead looking for a better way on as I simply didn’t believe that this nasty rift could be it. I got ahead of Rich and deployed my extreme-tek cave spotting torch and carefully examined the wall to my right. I noticed a pile of boulders a bit above me and, using Rich on the line as a lighthouse, swam up and over to have a look. I shone my torch down a large, ongoing railway tunnel of a passage which was ongoing as far as my torch could penetrate – at least 20 metres. There it was. The lost way on was stretching out in front of us. I signalled to Rich and he came over to have a look and we stared at each other in amazement.
Then, Rich tapped his watch and I tied two snoopy loops onto the line and built a rock cairn to signal to Joe and Oz where to tie their line off and we set off home.
We surfaced between sumps 1 & 2 to explain to Nathan what we had found. I stumbled over my French in excitement but he got the idea! Nathan had surfaced in the airbell found by the British team 3 years ago and confirmed it as a ‘cloche’ – closed off airbell.
We all dived back to base and Oz and Joe kitted up. I gave them very clear instructions and directions about what we had found and what to look for. We left the line reel for them in between sumps 1 & 2.
Meanwhile, Rich and I got changed into something more comfortable and began hauling gear with the help of Nathan, back up the pitches. We got everything except Oz and Joe’s kit out of the cave by the time they returned.
They had tied into the line at the cairn and set off down the railway tunnel – which Joe declared was far bigger than any railway tunnel he had seen – and laid 36 metres of new line to a depth of 30m where gas reserves turned them around.
Osama and Joe kit up in sump 1
We hauled their gear out and began the soul destroying task of getting kit back to the cars which ended in doing so by torchlight as the moon rose steadily.
The day by far exceeded our expectations and a return trip this week is planned to resurvey sump 2 from scratch, as Nathan does not have proper data - and survey the new line and add some more, having decanted as much trimix into exploration bottles we can, in case it goes deeper.
Nobody wants to do deco in this cave in wetsuits.
![Push [Poŏ SH] - by Rich Walker](https://images.squarespace-cdn.com/content/v1/652d025f8e316238da9f6267/1701721593090-NQBMIM6BSQVV3174KHML/file_1440x1080_014833.jpg)
Push [Poŏ SH] - by Rich Walker
It sounds a bit silly really. To push a cave. A cave is an empty void, and difficult to push in the conventional sense like you would push a car that won’t start. Pushing a cave means, to the cool kids, to extend the limit of exploration. To go further in that cave than anyone has been before. You have to be careful here as it is very easy to sound like you are lost up your own arse. I suppose that would need some sort of pushing to rectify as well.
Kit stash at the bottom of the pitch in Perdreau-Fourmi
The Perdreau Formi is a bit of everything in a cave sense. It starts with an awkward boulder choke at the entrance. For the uninitiated, a boulder choke is a pile of rocks, stuck and hopefully wedged in the passage of a cave. We are fortunate that this choke is normally dry, so we can get through it without dive gear. This often involves some pushing as well, but more like what you would do with a car. Or a turd.
Once you have got past the choke, you arrive in a large chamber at the top of a 45degree slope. The slope is slippery, but manageable. We put a rope on it though and descend down the slope well protected as at the end of the slope is a vertical drop, 20m high. If you were to loose your footing on the slope and fall off, you might be lucky to land in the sump with a splash, but you would probably bang on a few rocks on the way down, and more likely splatter somewhere in the boulder strewn area at the bottom. You might survive, but then you’d be faced with being pulled up the 20m pitch, up the slope and pushed (there’s that word again) through the boulder choke again.
Tim Webber and Jarvist Frost had done a fantastic job sorting out the vertical section of this cave. They had built a system of tensioned lines, pulleys, hauling lines and brakes that would have looked good on a Spanish galleon. Moving the equipment up and down the pitch was considerably easier than the brute force methods we’d employed last year, and made the trip run significantly faster.
Christine kits up in sump 2
The sump at the bottom of the pitch is well lined, and normally clear. We dived it last year and it was a short, but very pretty trip. The walls are white and the water has a blue tinge to it. The passage twists around, through an easy restriction to a maximum depth of 19m, where it comes up steeply into a large airbell.
It takes about 5 minutes to cross this sump, whereby you are faced with a steep wall 3m tall, at about a 70degree incline. The way on is this way. Climbing the wall is precarious, but manageable with small cylinders. The second sump is found on the other side of this wall at the bottom of a couple of round pots.
Tim and Jarvist had been hard at work in the airbell too. They had installed for us a wire ladder to climb the wall, a gear line to clip off bigger cylinders and similar assistance on the descent into sump 2. This was to be critical when we returned later in the week.
Junction formed by Christine in 2011 when she discovered the way on in the Perdreau-Fourmi sump 2
Diving in the second sump, the line is not so good. It is often loose, and many belays have come free, so the first dive this year was to check the state of this line, effect some repairs and to have a quick look to the end of the line laid by Joe Hesketh and Osama Gobara on last years project. Their line was excellent and the reel was there waiting for our return. The line ended at a depth of 29m.
The passage had dropped down 20m from the tie-in on the main line and we had been concerned about the cave heading into deep water. Spending a few minutes looking at the way on was time well spent, as it seemed that the passage levelled off, at least for as far as we could see. This was good news to us - shallow means more time exploring and less decompression.
Christine and I had a chat back at the surface about our decompression strategy. We had expected the cave to head deeper much more quickly than would now appear, which would require a more significant decompression strategy - this in simple terms meant a lot of decompression gas was needed.
Given our look at the end of the line, we decided not to pull in the big decompression cylinders, and stick with a smaller volume of oxygen, for use at 6m, rather than the big cylinder of 50% nitrox for 21m decompression. This was a gamble, but would make the logistics significantly easier. For our return dive to “push” the cave, we had mixed gas for a maximum of 60m in two large 15 & 12L cylinders each, and a small 5L cylinder filled with oxygen for decompression. We were diving in wetsuits, which in 11C water would be a push on a longer dive, but as long as we limited the dive time to an hour, we figured we’d be OK.
New passage from 2011 explorations
On the day of the dive, the gear went in very smoothly with assistance from Jean Tarrit and friends from the CLPA. These people have been so good to us in our efforts here, and never fail to turn up to help out. It’s not always the same people though, so maybe word is getting out ;-) All we needed to haul in was the cylinders, the deco gas and the wetsuits, as we’d left all of the other gear in after the first dive.
Chris and I dived through sump 1 and were ably assisted by Tim and Jarvist, and we pushed and they pulled our heavy cylinders up the rope to the start of sump 2. Kitting up in sump 2 was a bit more awkward, but again our helpers did a sterling job of pushing us into the water ready to dive. The oxygen was handed down, and we set off.
After depositing the oxygen at a suitable place to do the deco, we headed off down the line. This had come loose again and floated into the ceiling (I hate blue polyprop). We missed the junction as it had itself floated into and behind a crack in the ceiling, and we arrived at the old end of the line. Very puzzled, we backtracked, and this time spotted the junction, more visible from the other angle. We still weren’t pushed for time, so we headed off to the end of the line. Pushing on through a patch of low visibility left from our dive 3 days previously, we soon came across the start of Joe and Osama’s line. Junction marked, and away we went, soon reaching the reel that had been waiting a year for our return.
I picked it up, and looked at Chris. She had her survey gear out, and we exchanged an OK and we started to swim. I like to keep the number of tie offs to a minimum, and if possible to have spotted the next one before I leave the current one. This makes the surveyors job much easier, as the line doesn’t wave around, and tying off takes time, slowing down the act of pushing. The cave made this pretty easy, as it soon turned from large open passage into a narrow rift, 2m across at an angle of about 45degrees.
It was probably 20m high in places, pale walls with delicate mineral veins extending from the rock. It was pretty silty, and as usual in places less well travelled, percolation from your bubbles traveling up the walls quickly reduced the visibility, meaning that constant motion is preferable. I put in 6 tie-offs before the reel was empty, a total distance of around 50m. Looking ahead, the rift appeared to get narrower, although probably passable. My gut tells me that there is something else though. Maybe it surfaces at the top of the rift, or perhaps there is another connection we have missed along the new line.
I glance at Christine thimb the dive. She returns the compliment and we head for home, 25 minutes after leaving the airbell. Now it was time to see how well my line was laid and whether it was easy to follow in low visibility. My ability to write the blog says that it was good enough, I suppose.
We got back to the oxygen and given that the dive had not gone anywhere near as deep as expected, decided to not bother with any decompression and get back to the warm. We surfaced at around 40 minutes, with an empty line reel, my knife that I had found after loosing it on the first dive and a full survey of the line we’d just laid. A proper good day out!

We had a great time in Wales recently at the Old Rectory in Llangattock for the 71st anniversary of the Cave Diving Group of Great Britain.
We spent the Friday afternoon diving in a cave called Porth yr Ogof in the Brecon Beacons, to take some visibility measurements and collect some data for our conservation project, Project Baseline South Wales Caves.
On the Sunday, Rich and I joined award winning cave photographer Mark Burkey and his wife Jess for a casual trip into a cave called Ogof Ffynnon Ddu. We played with video shots for an upcoming project and Mark showed me some tips and tricks to get more out of my camera underground – we think you’ll agree the results were stunning!
The secret cave
Before I go into details of our dive here, I should stress that this cave is not for public access and is indeed the water source for the town of Millau. Permission is required to dive here and we obtained this through a friend and a French cave diver before visiting the cave. Illegal dives here are quite likely to spoil ongoing attempts to reach an agreeable solution about diving the source, hence I have withheld its whereabouts.
The plan was to video the cave and as a result, will offer any footage we have to the local speleo activists to use in their quest to demonstrate how important divers are in the protection of caves and scientific hydrological research. At the end of the day, we are the only ones who can actually see what goes on under the water, under the rock, in the dark.
We drove almost 2 hours on nothing but winding roads and stunning gorges until we reached the village and after a little inventive French speaking and some friendly locals, located the source. We parked up but our French guide, Mehdi, was not there. Worried, I made a few calls back home to some friends who knew him but there were no such worries, as he showed up minutes later, having been diving in the Font d’Estremar all day!
We began carrying kit to the cave and we spoke to Mehdi in our best going out French and he spoke to us in pretty good English. He was to dive with us and both Rich and Joe had video cameras.

Due to gas logistics (there are no filling stations down here, so all trimix was pre-filled, as were deco gases – the rest is to be topped off by the compressor, courtesy of the Derbyshire Section CDG) Rich and I dived sidemounted as these were the only ‘backgas’ cylinders we had left which could be used, the rest still full of 15/55 for next week.
So we dived on 60m gas to reach pretty much the terminus of this cave, which ends in a jumbled, jagged breakdown choke at -65m.
The journey there however, was spectacular. Clive Westlake, my ex-CDG mentor was the last person to dive here 4 years ago and prior to that, the last diver had been in the cave no less than 8 years ago. And it showed.
Our exhalation bubbles sent bits of conglomerate and chert raining down on us and wafting past the video cameras. Anything you touched simply broke off in your hand so we dived it with kid gloves. The entrance is a narrow rift and we dropped off our deco bottles as we followed the winding, ‘diaclase’ (maze) to the head of a shaft.
I’ve seen some impressive underwater shafts, some pretty famous, but this was one of the more pretty and intricate ones. Mehdi dived a Megdalon ‘recycleur’ and stealthily crept along behind us, grinning in awe at the view he was presented with, descending above Rich with his double 18W filming lights, above me with my HID… he said it was pretty amazing! The visibility was infinite and sparkling blue.
I saw the line snaking off towards the breakdown terminus and thumbed the dive at 59.9m. We had a nice ascent and Mehdi began chatting to me through his RB and I felt obliged to waffle some crap in French back!!
We picked up our deco gases and Rich filmed Mehdi down some side passage while I wrestled with getting an ali stage clipped off to sidemount 12s, all the while feeling a bit underweighted; I soon realised that this was due to a sticking wing inflator valve which was filling my ‘Scoff-Bag’ at a rate of knots. Giggling at my stupidity for not noticing it sooner, I told Mehdi I was fine and that I would deal with the simultaneously freeflowing regulator later……
Such annoyances don’t spoil a great dive like this though and we surfaced at dusk, waffling in barely coherent Franglais at how good it was and how worth the drive etc etc.
I asked Mehdi if he would please join us for dinner, or a beer at least. One step ahead, he produced a bottle of delicately balanced local white wine which had been cooling in the resurgence all the while!!
We waited for the others to surface and giggled uncontrollably as they had stuck true to form, getting totally lost and taking the wrong line and ending up in some shit-hole about 0.5m high and full of mud, unable to turn around etc. They did make it to the deep in the end but they won’t live it down as it’s not the first time either!
The stars started to come up over the gorge and the white limestone cliffs were lit by the moon and we tore down the gorge after Mehdi who showed us to a very welcome pizza restaurant and made sure we were looked after.
An absolutely awesome dive, great company and a superb evening. Days don’t get much better than this. Thankyou guys.
