The purpose of this paper is to report on glaciological investigations carried out at a single glacier in this region, the Rae Glacier. In 1990 and 1991 field research was completed to describe the physical glaciology of Rae Glacier
and to characterize historical glaciological trends at the site. The glacier has a lag time of 5 to 10 years, which confirms that it is sensitive to climatic fluctuations and responds to changes in mass balance within a very short time. This observation is supported

The Debeli Namet glacier is one of two recent glaciers located in the south western Balkans, (Durmitor Mountain). The glacier is reducing at a rate slower than that of other southern European glaciers. It did not significantly fluctuate in size
in response to temperature increases that occurred at the end of the 20th and at the beginning of the 21st centuries. The A. presents partially revised data accompanied by results related to the glacier’s recent behaviour, its surroundings and climate. - (IKR)
The intent of this work is to : 1) present surface velocities on 15 rock glaciers averaged over 12 years (1983-1995) in the Selwyn Mountains; 2) calculate long-term velocities using rock glacier length and lichen age; 3) compare the velocities

Several factors influencing glacier mass balance vary with slope aspect. Their effects can be measured by either vector analysis of the number of glaciers with each aspect, or Fourier regression of glacier altitude, or size against aspect. Both
approaches are applied here to large data sets from the World Glacier Inventory, for all available regions. Favoured aspect is measured by direction of the resultant vector mean and by the direction of minimum glacier altitude for 51 regions with a total
Variations of italian glaciers between 1980 and 1999 inferred by the data supplied by the Italian Glaciological Committee

The study synthesises the analysis of those data relevant to the variation registred in the Italian glaciers during glaciological surveys carried out by the Italian Glaciological Committee between 1980 and 1999. The last twenty years of the 20th
century were characterized by a phase of general retreat of the glaciers, that followed an advancement phase that took place in the 70s and in the early 80s. The data matrix, which is largely incomplete, includes 335 glaciers. - (NF)

The study has estimated the reduction of the glaciers of Mt Antelao (Dolomites, Italy) from the Little Ice Age (LIA) to today using bibliographic and morphological data as well as modern techniques of data elaboration and processing. - (NF)
A model for sedimentation by surging glaciers is developed from analysis of the debris load, sedimentary processes, and proglacial stratigraphy observed at the Icelandic surging glacier, Eyjabakkajükull.

In this paper, the AA. discuss stable isotope and stratigraphic data from an ice core obtained from a rock glacier at Galena Creek, northwestern Wyoming, USA. They have presented new, independent evidence that the Galena Creek rock glacier
is genetically a temperate alpine glacier. These findings show that the Galena Creek rock glacier, and perhaps many other rock glaciers, are essentially debris-covered glaciers. The AA. suggest that rock glaciers represent an untapped archive of old glacier ice
This paper provides a review and a synthesis of the work done between 1981 and 1995: detailed studies of surface velocity, glacier hydrology and ice dynamics. Small glaciers, such as Storglaciären, are not as sluggish as may be expected but exhibit

Several contentions issues have arisen from rock glacier nomenclature, for example whether the term rock glacier implies genesis from glacial ice or from permafrost. The situation is compounded since rock glacier classification may be based

With the purpose of improving the ice physics underpinning time-dependent glacier flowline models, 3 independent approaches for solving longitudinal stresses in glaciers are discussed and verified by application to Haut Glacier d'Arolla
. The longitudinal stresses play a significant role in determining glacier dynamics on length scales up to at least 2 km and that predictive power of models of glacier flow based purely on the driving stress approximation is therefore subject to significant
