Abstract:

This paper assesses the amount of area and volume retreat, from the maximum expansion phase of the Little Ice Age to date, of glaciers at the head of Valpelline and Valtournenche (Valle d'Aosta, western Alps, Italy) using field survey, air-photo interpretation, analysis of historical records and a geographical information system. The calculated areal retreat value is 42.34%. For the upper Valpelline glaciers, the area declined from 20.13 km2 to 14.78 km2; whereas for the upper Valtournenche glaciers, a loss of 14.78 km2 to 5.8 km2 has been recorded. The estimated ice-volume loss was 0.35 km3.

  • The Annals of Glaciology is a peer-reviewed, thematic journal published 2 to 4 times a year by the International Glaciological Society (IGS). Publication frequency is determined and volume/issue numbers assigned by the IGS Council on a year-to-year basis and with a lead time of 3 to 4 years. The Annals of Glaciology is included in the ISI Science Citation Index from volume 50, number 50 onwards.

    Themes can be on any aspect of the study of snow and ice. Individual members can make a suggestion for a theme for an Annals issue to the Secretary General, who will forward it to the IGS Publications Committee. The IGS Publication Committee will make a recommendation for an individual themed Annals issue, together with a potential Annals Chief Editor for that issue, to IGS Council. The IGS Council will make the decision whether to proceed, taking into account the spread of topics and the overall capacity for publication of pages in Annals.
