Abstract

Equilibrium-line altitudes on the White Glacier, Axel Heiberg Island, and the north-west sector of the Devon Ice Cap were shown to be closely related to mean July freezing-level heights at nearby upper-air weather stations. An inverse relationship between July freezing-level heights and mass balance on the Devon Ice Cap was also shown. Reasons for such correlations were suggested and some limitations of the relationship were outlined. Recent lowering of the freezing level in July was discussed in relation to the theoretical 'steady-state' equilibrium-line altitudes in the Canadian High Arctic. It was suggested that positive mass-balance years have predominated over a large part of Northern Ellesmere Island and North-central Axel Heiberg Island since 1963, and some glaciological evidence supporting this hypothesis was given
