The purpose of this study is to study the processes, both active and inactive, which influence the formation, structure and distribution of subalpine heaths in the Abisko Valley and to compare their ecotope with the adjacent birch forest.
La région d'Abisko, en Laponie suédoise, constitue depuis dix ans un espace très intéressant pour l'étude du périglaciaire et en particulier les paléo-climats, la limnologie et l'écologie.

Statistical-empirical modelling of mountain permafrost distribution in the Abisko region, sub-Arctic northern Sweden
Abisko ; Analyse de régression ; Changement climatique ; Distribution spatiale ; Modèle ; Montagne ; Pergélisol ; Périglaciaire ; Statistique ; Suède ; Température du sol
The aim of this study is to quantify lower permafrost limits in the Abisko region by means of independent proxy data (BTS) and statistical analysis. The results serve as a basis for evaluation of climate and environment permafrost relations
Observations on sorted circle development, Abisko, Northern Sweden
Etude du développement des cercles de pierres, près d'Abisko (Suède septentrionale). Présentation et discussion des résultats des mesures effectuées pendant 2 ans, pour suivre les soulèvements par le gel, les tassements au dégel et les mouvements
Altitudinal zonation of selected geomorphological phenomena in an alpine periglacial area (Abisko, northern Sweden)
The objective of this study is the search for an altitudinal zonation of geomorphological phenomena in a small, alpine, periglacial area. Because the Abisko region shows a large altitudinal range, a variety of geomorphological phenomena and a minor
Observations on regional variation in solifluction landform morphology and environment in the Abisko region, northern Sweden

Turf-banked lobes and terraces on the valley slopes and stone-banked or non-sorted lobes at summits show a distinct regional trend of decreasing size from west to east in the Abisko region. Significant correlations with environmental parameters
Glacial erosion in the Abisko Mountains : Kärkevagge and Vassivagge, northern Sweden
This paper discusses direct current resistivity soundings and geomorphological studies of Quaternary deposits in 2 glacial throughs in the Abisko Mountains of northern Sweden. The subject of the fieldwork is the depth of Pleistocene glacial erosion
. Studies were carried out in 1998 and 2003 in the Kärkevagge and Vassivagge. The estimated thickness of Quaternary deposits and bedrock properties are discussed in the broader context of glacial erosion studies in the Abisko area.
