Thinning Arctic ice may cause drifting research stations to be placed on firm ground or artificially-made platforms, the head of Russian Meteorological Centre said on Thursday.
"We have to think about using some... constructions, instead of blocks of drifting ice as platforms," Alexander Frolov said.
Russian and Soviet polar scientists have used drifting ice stations in the Arctic Ocean since the 1930s.
A new Russian drifting polar station started work in September 2009. However the ice it was placed on has begun to break up and the station will be removed in June.
