No doubt you've both seen the Wikipedia entry for this?
The ambitious project to establish a permanent church or even a monastery on Antarctica surfaced during the 1990s. A charity named Temple for Antarctica (Храм - Антарктиде) was approved by Patriarch Alexius II and received donations from across Russia. They organized a competition for the project that was won by architects from Barnaul P.I. Anisifirov, S.G. Rybak and A.B. Schmidt.
Maybe it's this charity or the Russian Orthodox Church which is supporting Father Georgy.
The article mentions 20 years experience rather than 20 years residency. It would be interesting to find out which. Maybe the Temple for Antarctica charity could cast more light on this.
