AB: Glaciological observations were done on McCall glacier in Alaska in May, 2004. Snow and ice core sampling were done by a hand auger at 7 points along a line from a basin in accumulation area to a ridge. From this sampling a thickness change of firn layer was obtained, by which the formation of internally accumulated ice layer was outlined. Internal ice layers were detected by GPR (Ground Penetrating Radar), by which distribution of snow accumulation in the accumulation area was observed. By an image recorder, snow accumulation was observed everyday in a year. The maximum accumulation was about 1 m cm in snow depth, but it was all melt and the surface mass balance was negative in the accumulation area in 2003-2004.
