ACCUMULATION RATE ON THE ICE SHEET SURFACE IN EAST QUEEN MAUD LAND, EAST ANTARCTICA
In the East Queen Maud Project from 1981 to 1987,accumulation rate on the ice sheet surface was observed in an extensive inland area by the stake-method. Along a traverse route from Syowa Station (69°00'S, 39°35'E, 21m a. s. l.) to Dome Camp (77°00'S, 35°00'E, 3761m a. s. l.), va...
