You can look at some of their data analysis at
<http://cavex-team.org/archive/voronja2005topo.html>. Helps if you
know Russian, but you can still get a lot out of it since part of it
is in English. My online machine translator (Systran) gave a
decently readable translation. The name of the project is Wonderland
2005. The first column of data is from the hydro-leveling
(water-filled tube, basically. See Australian Caver No. 109, pp
10-13 (1986) for an article on the technique.). I'm not sure what
the second column is (it just says survey - maybe using
altimeter). The third column is Suunto ("real" survey, but it
doesn't go all the way down the cave). They averaged the results to
get -2140 m. There is also a profile line plot labeled with some landmarks.
