Could anyone posting information about bad air in a Mendip cave please include the barometric pressure for the time of the trip and a summary of the pressure for a couple of weeks before.  This information is available from: http://www.mendipweather.org.uk - the site shows the current weather and the last 30 days.

July 2008, Poor air in Swildons Hole; noted Sunday 20th.

10:40am-12:00pm
Barometric pressure: 997

Pressure in preceeding weeks >=1005-1010

Suggest reason for poor air is recent heavy rains washing in organic detritus which is now rotting in situ.

No reason to stay away; merely pointing out that the air in the cave isn't pure and wholesome - it won't kill you or nuffin*. In fact, come to think of it, there's nothing wrong with the air in the cave whatsoever, unless you happen to like running everywhere and prefer not to be out of breath while doing so.

Bad air in Cuckoo Cleaves on Thursday 24th July evening.  Seemed to be a problem at the bottom of the ladder even though there was a draught and by the bottom of the climb we turned round and had difficulty getting out.  It's really dangerous at the moment.

For the record (Because Mendip Weather Station not working):
Pressure approx 1016Mb and it has been quite windy over past week (i.e. pressure has not been constant).

I suppose this was the group who went down Cuckoo Cleeves before us yesterday -- group of 4/5? They told us as we went in that the air wasn't great. We got down as far as a streamway (it didn't seem very far on the way in, I hadn't been in the cave before) before deciding that the air really was quite bad. Getting out was a real struggle, very unpleasant. Certainly the worst air I've experienced in a cave.

I'd recommend being careful with this cave, especially if more than one group is going through it on the same day.

Sunday 12th October 2008:

4 of us experienced bad air in Swildon's Shatter Series in the U-tube/Junction Chamber area.

We were all breathing very heavily and with me being in Junction Chamber on my own was feeling unwell/faint. Good efforts by all for evacuating the area as quickly as possible  :thumbsup:

Afterwards I was informed that it was the worst time of year for this part of the cave due to the decay of vegetation.
Think it's worth passing on the message as it was a scary experience for us. A note has been left on the board in the Wessex hut.

Following a recent trip to Compton Ochre Mine I wish to report that the members of our club that visited found that the lock was broken and so was the gate.
Could someone pass this on to the powers that be.

Many thanks

Just left a message for Les, Thanks Mark. I for one would love to find out who did this, obtaining access with a CSCC key is so simple too.

Not a problem. I'm just sorry that through my amazing secretary powers I gave you all the message about two weeks too late. Completely disorganised T**t am I.

Bad air in Manor Farm, Saturday 8th Nov 2008.

Around entrance to NASA gallery but in the main streamway. Rain had been heavy for the previous 2 days so I guess the silt / poo combination had been stirred up.

Both myself and 3 clients experienced gasping for breath and dizzyness, so made a hasty retreat upwards. One client ( a smoker so this may not be related to the air quality) was having to stop frequently to catch his breath.

Bad Air in Cuckoo Cleave (July 2009)
« Reply #21 on: July 04, 2009, 07:43:33 pm »
Went in on Thursday (03/07/09) with a friend and were both endurance runners so were fairly fit however we realised that we were breathing heavy and after resting for five minuets we were still panting. We also used one of those wind resistant matches that normally light like a flare but this just fizzled! We were stumbling and slurring our speech, but when we came out I recovered pretty quickly but my friend has had a 48 hour head ache. Thought Ill give the heads up.

I wonder why Cuckoo is the most common bad air cave,
there must be something different about it.
If we could figure out what, then just maybe, we could glean an inkling in CO2 in general, in caves on Mendip.
I have never noticed a problem in Yorkshire caves.
This is surely a university type project awaiting a university type.

There never used to be a problem when we were digging, banging the bottom of the cave years ago. One theory i have is the gates don't have open holes for the locks like they did have (GB is another similar case) it may be only a small air way but it is the only change that is obvious.

A bat access hole was created into the GB blockhouse when the gate hole was blocked. The bat access hole is actually larger than the original hole in the gate so I don't see that change as being material with CO2 levels in GB. Don't know about Cuckoo though.
