Oggetto: [EKPP] EKPP French cave exploration
The EKPP (European Karst Plain Project)  pushed the Doux de Coly on August,
22 to 5675 mtr (18618 ft) distance to air.
The dive started in the morning of August,22 at 7:03 am and lasted 18 hours
21 minutes. The divers Michael Waldbrenner and Reinhard Buchaly surfaced in
the morning of August, 23 at 1:24 am.
675 meters of line were added and surveyed from their  5000 mtr endpoint of
the last year.
Both divers used a double RB80 rebreather configuraton with 2x 20 liter
backmounted bailout cylinders (trimix 16/80). Three drive stages were used
with 2x trimix 22/70 and 1x 16/80 and five magnum Gavin scooters per diver.
All rebreathers were fitted with a custom counterlung optimized for the
depth of the cave.
Lighting was with a 18 Watt HID with a custom made reflector powered by 20
Ah Nicads.
The dive started with a visibility of 15 to 20 meters ( 50-65 ft). Due to
heavy rainfalls two days ago the vis reduced after approx. 1000 m (3300 ft)
distance to initally 4 meters (13 ft) , then 2 meters ( 6 ft) visibility.
Luckily the vis improved again after 2300 meters (7500 ft) to the starting
vis.
Again at 4500 mtr (14700 ft) the vis went down, but it improved after
further 200 meters.
When reaching the endpoint of the last year at 5000 meters (16400 ft) it was
expected that the cave would continue the downslope. But it stayed at a
level between 65 and 60 meters (213 - 197 ft). The cave got smaller at 5300
meters (17400 ft) where the tunnel ended in a T. Choosing the way to the
right, the now smaller and silty tunnel went in eastern direction til the
line was tied off at 5675 mtr.
Bottom time was around 8 hours. The decompression took place in the shaft
300 meters from the entrance. Total deco time was about 9 hours 15 minutes.
Additional time was spent travelling the shallow part and entering and
exiting the habitat for the last three hours of deco. Water temp is around
12,5° C.
Both divers felt well after the dive, and after a good sleep jogging the
next morning showed no lung problems.
A more detailed description of the dive and the team effort will be placed
on a website in a few weeks.
We want to thank our great DIR support team for their excellent work.
We had a lot of fun within the team and enjoyed the dives.
Reinhard Buchaly and  Michael Waldbrenner

Hai notizie certe che e' un bluf....
A me sembrava decisamente ironica come introduzione. :o)
Il record e' stato fatto, eccome!!!
Tato

quest'anno il record.
Se per te 5000 metri di penetrazione sono un giretto...
Quest'anno si sono solo *spinti* un po' oltre battendo un record gia'
loro in quel sito.
Se a qualcuno interessa il report dello scorso anno:

Oggi sono andato all'Ikea per comperarmi una mensola.
Non l'ho trovata e sono uscito con un salmone.
Sono tornato a casa, l'ho aperto e, vaffanculo, era da montare!

 L'ironia non e' il tuo forte eh ?
e' colpa dell'offuscatore. ;-)
