| Research Abstract |
Snow surface roughness from coast area to Dome Fuji Station (1000km inland form the coast) on the Antarctic ice sheet was investigated using 3Daccelerometers mounted in snow vehicle and on snow sledge. We clarify the characteristics of snow surface roughness along the traverse route using the data. We also carried our snow stake measurements at 36-stake farm at Dome Fuji Station from 2008 to 2012. Weclarify that the annual surface mass balance (ASMB) at Dome Fuji since 2008 has atendency that annual variation of ASMB becomes large compared to the data from 1995 to2007. We also investigate the influence of solar radiation changes to air temperature on the ice sheet using the meteorological data during the total solar eclipse at November 14, 2003. We found the characteristics of the air and snow temperature variations caused by suddendecrease of solar radiation.
