The result of 18 year's record (1958-1976) of accumulation and ablation from the Ward Hunt ice rise and of 10 years record (1965-1976) from the Ward Hunt Ice Shelf are presented. The net mass balances on the ice rise for the years 1962-1965 and on both the ice rise and the ice shelf for 1972-1975 are positive. The net mass balances for all other years are negative. There is only fair correlation between the net ablation and the mean summer temperatures at Alert since the ablation rate is sensitive to several other factors, notably the surface albedo.
