Antarctic Record (Aug 1975)
A Steam-Operated Drill Used by the 14th Japanese Antarctic Research Expedition (1972-1974)
Abstract
A steam-operated drill similar to that of S. M. HODGE was used to measure 10m snow temperature at Mizuho Plateau, East Antarctica, in 1973/74. The average drilling time for firn was 22 min (depth 10m, diameter 3cm, firn temperature about -20℃).
