The contribution of geoelectrical investigations in the analysis of periglacial and glacial landforms in ice free areas of the Northern Foothills (Northern Victoria Land, Antarctica)

Auteur(s) et Affiliation(s)



Description :
All periglacial and glacial landforms investigated in the Northern Foothills have a very thin active layer overlying a thin permafrost layer, characterised by electrical resistivities and by different thicknesses. Below this surficial layer, different types of ground ice were detected. These different types of ground ice permitted ice-cored rock glaciers to be distinguished from ice-cemented rock glaciers, subsea permafrost to be identified in some raised beaches, and other interpretations to be suggested about a debris-covered glacier. These reults have been obtained by vertical electrical soundings (VES) during the Italian expedition (1994-1995).
