The flow velocity of about 2500m/year was obtained for the Shirase Glacier (70°S; 39°E), East Antarctica, by the analyses of aerophotographs taken in 1969 and 1975. Thicknesses of icebergs near the termini of the glaciers located along the Soya Coast were also obtained from the shadows on aerophotographs. These data made it possible to estimate the amount of discharge of ice more accurately than ever made. The total discharge from the Mizuho Plateau area across the Soya Coast is estimated at approximately 8.9×(10)^9t/year, which comprises 7.4×(10)^9t/year from the Shirase Glacier and 1.5×(10)^9t/year from other glaciers and the ice sheet.
