Abstract
The mass balances of White and Baby Glaciers, at 79° N on Axel Heiberg Island in the high Arctic of Canada have been monitored more or less consistently since 1960. Photogrammetric estimates of terminus fluctuations are available for White Glacier and its larger neighbour, Thompson Glacier, from relatively frequent photographs dating back to the first recorded image in 1948. In addition, an ice-off (breakup) record of Colour Lake, located between White and Baby Glaciers, is available to 1959. These data series, up to 1997, are presented. While the glacier records show an excess of ablation to accumulation and so suggest warming, the lake ice record and the advance of Thompson Glacier seem to indicate cooling. These records are of special significance because they are indices of conditions at nearly 80° N, where global climate models suggest that warming should be most pronounced. However, the large-scale significance of such local records should, of course, be assessed with caution.
