Description
Summary:The terminus of Bunde Glacier (name used here for the first time), situated at 80 25 N, 93 45 W on northwestern Axel Heiberg Island, Canadian Arctic Archipelago, was observed and photographed in 1955 and 1983. Comparison of the photos indicates that there has been no appreciable advance or retreat during the 28-year span, as the terminal moraine appears to have remained practically unchanged. The possibility exists that Bunde Glacier retreated or advanced after 1955 but re-advanced or retreated to occupy its 1955 position by 1983. This situation marks a departure from the observation that glaciers in most parts of the world are in retreat. En 1955 et 1983, on a observé et photographié le front du glacier Bunde (c'est la première fois ici que l'on utilise ce nom), situé par 80° 25' de latit. N. et 93° 45' de longit. O., sur la partie nord-ouest de l'île Axel Heiberg dans l'archipel arctique canadien. Une comparaison des photos révèle qu'il n'y a pas eu d'avance ou de retrait notable durant cet intervalle de 28 ans, vu que la moraine terminale semble n'avoir pratiquement pas changé. Il est possible que le glacier Bunde ait reculé ou avancé après 1955, puis avancé ou reculé à nouveau en 1983, pour occuper la même position qu'en 1955. Cette situation signale une divergence par rapport à l'observation que sur la plupart de la planète, les glaciers sont en recul.
